Phantasmagoria of Dim.Dream English TranslationJapanese “ Touhou Yumejikuu Backstory Deep in the mountains in a country in the East, the Hakurei Shrine was mostly peaceful. The shrine maiden of the Hakurei Shrine, Reimu, was always getting wrapped up in strange circumstances (though it should be noted she was a bit strange herself), so her free time was when things were peaceful. Reimu: "Ah, what am I going to do with all this time on my hands. I wonder when something exciting is going to happen." When the protagonist is idle, something is required to happen. Reimu thought she'd get out of the shrine for a while instead of sweeping the garden, and so stumbled upon some ruins. Reimu: "Wait, what are these ruins doing next to the shrine. They weren't there yesterday!!" (something happens!) Mima: "Oh, Reimu. So you came, too." Reimu: "Great, it's Mima. Hmm, actually, it looks like there's a lot of people here ... " Reimu: "What is it with this ruins, anyway?" ... Mima: "It's said that something is asleep deep in these ruins that will grant happiness to whoever comes to visit it." Reimu: "Whatever, that sounds like something someone would say to get people to join a cult. Besides, none of this was even here yesterday. So what's up with that so-called prophesy?" Mima took out a folded piece of paper from her pocket. Reimu took it and unfolded it. This was written on the paper: The ancient ruins: "Fantasy Ruins" Grand opening, 10am today 　　　　　　　　　　　　　　　　　　　　　　　・・・・ To you who visit the ruins, we present something to make you happy. Our sincere thanks to everyone who stops by. Reimu: "Hm!" Reimu: "What's with these pamphlets? (How is this some sort of ancient prophecy?) How can ruins have a grand opening? And none of this was here yesterday! How can you all be taken in by something that's so obviously suspicious!?" Marisa: "Hm, so Reimu's not interested. That must mean..." Reimu: "...Who said I'm not interested?" Reimu: "Er, actually, I'm pretty busy (not), but having ruins suddenly pop up here is a pain to deal with. I have my complaints, you know." Mima: "Isn't it almost time for the grand opening? I don't see an entrance anywhere. I guess we'll have to wait for now." Reimu: (Man, when did this... well, I guess this is pretty normal around here... huh?) Reimu: " ... it looks like there's a notice posted over here." Marisa: "Wow, really? Hey, what's it say?" Inside the Fantasy Ruins Capacity: 1 person The capacity must be strictly observed. If the capacity is exceeded, then we can no longer guarantee the existence of these ruins in this dimension Reimu: " ........ ?" Mima: " ... so, that means ... " Marisa: "fufufu ... " All together: "The battle is on!!!" „ ~ Phantasmagoria of Dim.Dream Prologue English Translation “ 東方夢時空バックストーリー ここはとある東の国の山の中、博麗神社はおおよそ平穏だった。 博麗神社の巫女、靈夢は、実は変なこと巻き込まれ体質だった（本人もちょっと変）ので、変なことが起こらないと暇でしょうがないのである。 靈夢「あ～ぁ、ひまでしょうがないわ、なんかどひゃー　っていうようなことおこんないかしら。」 主人公が暇なときに、なにも起こらないはずがない。 庭を掃除しようと神社から出てみると、靈夢は遺跡を発見したのだった。 靈夢「なんで、神社の隣に遺跡があるのよ。昨日まで無かったのに！！（どひゃー）」 靈夢「げげ、魅魔。それに、よくみるといろんな人がいる～」 靈夢「一体なんなの、この遺跡は～」 ・・・・ 魅魔「古くからの言い伝えによると、この遺跡には来た者をしあわせにする何かが、眠ってるみたいよ。」 靈夢「なによ、その怪しげな宗教の勧誘みたいな言い伝えは。それに昨日までこんなもん無かったわよ。なのになんなのよ～、その言い伝えってのは～。」 ポケットから折りたたまれた紙を取り出す魅魔。靈夢がその紙を広げてみる。その紙にはこうかかれていた。 いにしえの遺跡、‘夢幻遺跡’ 本日１０時　開店 .... この遺跡に訪れた方には、あなたをしあわせにする何かを プレゼントします。皆さんのご来店を心よりお待ちしております。 靈夢「どてっ☆」 靈夢「なによ～、このチラシは～（どこが古くからの言い伝えよ～）。遺跡が開店～？　しかも、昨日まで何も無かったのに～。　あんたたちは、こんないかがわしいチラシに騙されて、のこのことやってきたの～！」 魔理沙「なるほど、靈夢には、興味が無いのね。ってことは・・・」 靈夢「・・・だれが、興味が無いなんていったのよ。」 靈夢「私はいそがしいんだけど（嘘）、こんな所に遺跡ができちゃったら迷惑だわ。ちょっと文句を言ってくる。」 魅魔「まだ、開店してないわ。それに、入り口が見当たらないの。とりあえず待ちね。」 靈夢（やれやれ、何でこんなものが、ま、いつものことだけどね・・・ん？） 靈夢「こんなところに、立て札があるわ。」 魔理沙「えっ、ほんと？　なになに・・・」 夢幻遺跡内　定員　１名まで それ以上は、認められません 規定人数以上、入場された場合 この時空での遺跡の存在は保証 出来ません 靈夢「・・・・・・？」 魅魔「って、いうことはー」 魔理沙「ふっふっふっ」 一同「　　勝負よ！！！」 „ ~ Phantasmagoria of Dim.Dream Prologue Japanese During the events of Phantasmagoria of Dim.Dream, Chiyuri composed an invitation flyer promising the granting of wishes to attract people to what she called the "ruins"—later revealed to be a ship. She manipulated the various heroines into fighting one another, intending for only the strongest to reach the interior. When the victor arrived, Chiyuri drew a gun on her to compel cooperation, believing this method was more entertaining. This approach drastically conflicted with Yumemi's intended plan for the situation, leading to Chiyuri being forced to battle the heroine so Yumemi could still gather magical research data. Chiyuri was defeated far more quickly than Yumemi had anticipated. She also interjects to stop Yumemi's threat of deploying a powerful bomb against the heroine after their final battle. Due to the conclusive ending of Phantasmagoria of Dim.Dream, it is currently believed that Chiyuri remains in Gensokyo alongside Yumemi, following their professor's expulsion from the academy. In Chiyuri's own scenario, she is portrayed as a native inhabitant of Gensokyo with the ability to use magic, becoming one of the many heroines competing for access to the ruins. Inside, she encounters and battles an alternate version of herself from another world to determine which is stronger, before then fighting Yumemi, who desires to study her magic. Afterwards, she departs Gensokyo by following Yumemi and her other self to the outside world, much to Yumemi's dismay that they cannot return. This narrative, however, presents a confusing contradiction.

Appearance

General Description: Chiyuri is a young woman with blonde hair and distinctive yellow eyes sporting a white sailor uniform.

Facial Features: Her most notable features are her bright yellow eyes and her blonde hair, which is typically worn at a medium length.

Clothing/Outfit:

• Primary Outfit: A white sailor uniform with blue detailing. The uniform appears too small for her frame. She accessorizes it with a blue neckerchief, a white hat, and a blue ribbon.
• Alternative Outfit (Gensokyo): A variation of her sailor uniform with red detailing instead of blue, paired with a matching red ribbon. This outfit is specifically associated with her incarnation from Gensokyo.

Special Features: N/A

Alternate Forms/Disguises: Her alternate outfit which is worn by the Chiyuri from Gensokyo.

Personality

• Deceptive and Mischievous: Chiyuri wrote an invitation flier promising the granting of wishes to lure people to a location she called "ruins," which was later revealed to be a ship. She then orchestrated conflicts among the respondents so that only the strongest would reach the interior, at which point she drew a gun on the winner to force cooperation, stating this method was more fun then simply asking.

• Competitive (Gensokyo Personality): In the scenario where Chiyuri is a native of Gensokyo, she participated in the conflicts to enter the ruins and fought her otherworldly counterpart to determine which of them was stronger before battling Yumemi.

• Opportunistic and Persistent: Following her defeat, Chiyuri remained in Gensokyo with Yumemi. In her scenario, after her battles concluded, she followed Yumemi and the other Chiyuri to the outside world, despite Yumemi's objections and the resulting inability to return.

Goals

Outside World ChiyuriGensokyo Chiyuri

• Help Yumemi with her research (Ongoing).

• Prove she is the strongest (Succeeded).

Relationships

Yumemi Okazaki

Yumemi is Chiyuri's senior and mentor, who entrusts her with tasks vital to her research and data collection. Despite this professional dynamic, their relationship is notably informal and frank. They speak openly to each other and often insult the others, resulting in them hitting each other.

Powers and Techniques

Innate AbilitiesWith Equipment

SharedOriginal ChiyuriGensokyo Chiyuri

• Superhuman Physical Characteristics
  • Superhuman Speed
  • Superhuman Reaction
• Genius Intelligence
• Sheer Will (When asked how do the characters have multiple "lives" in the game, ZUN notes that it's guts, so if they earn more points, it's them having more guts to continue fighting, while this may have initially been merely a joke, ZUN has elaborated that canonically, anytime Reimu and the gang are defeated, they challenge again however many times they want, but on the youkai side, they do not challenge again after being defeated and are not attached to the results of winning or losing)
  • Second Wind
• Breaking the Fourth Wall ( Touhou characters constantly acknowledge being a stage boss)
• Flight (Chiyuri is capable of flying off the ground and moving around to shoot out energy projectiles)
• Cartoon Physics (Gensokyo is a world that lacks and defies common sense, where characters can explode, this is even acknowledged with ZUN roleplaying as the characters in-universe that they explode upon defeat. Despite this they will still come back, even human characters that do not have regeneration)
• Non-Standard Interaction
  • Metaphysical Interaction: She is capable of harming Youkai like Mima with her attacks, where Youkai's bodies in truth are just their souls.
  • Possible Temporal Interaction: Has an attack named Time Cutter, implying that she is cutting time itself with the attack, though as it is just a name of the attack, it's dubious, support for this being legitimate, can be seen with her bomb Dream Clock, which causes an actual metaphysical clock to appear, meaning the attack names may be literal.
  • Possible Dimensional Interaction: Has an attack named Dimension Wall Cutter, implying that she is cutting dimensions itself with the attack, though as it is just a name of the attack, it's dubious, support for this being legitimate, can be seen with her bomb Dream Clock, which causes an actual metaphysical clock to appear, meaning the attack names may be literal.
• Non-Standard Damage (She is capable of harming Youkai like Mima with her attacks, where it's noted that one cannot defeat spirits or devilish powers without a weapon with an unnatural amount of spiritual power such as the Yin-Yang Orb)
• Non-Standard Defenses (She is capable of takings hits from Youkai, like Mima where a youkai's attacks damage one to a scale where they cannot recover from natural means)
• Observation
  • Unconscious Manifestation: Gods and buddhas are no more than youkai, yet youkai are hated while gods are worshipped, all being due to humanity deciding it should be that way. The form Nue takes has changed due to the various ways people have observed her. Humans created reasoning in order to explain all natural phenomena, thus every phenomena that could be observed therefore belongs to the human race, due to this, humans come to believe all but one, or perhaps even all forms of reasoning were false, spawnning youkai who were born from the natural phenomena and thoughts people have about them.
  • Truth Manipulation & Information Manipulation (Truth is built upon information just like a tower is built upon sand, most of the truths that are known are built upon information, thus truth is easily changed by informationa nd there's no such thing as information that concepts only but the truth as truth itself is the ultimate illusion, one that does not exist in Gensokyo)
• Curtain Fire
  • As a Playable
    • Directional & Rapid Fire: When shooting out a charged attack, she shoots out a multitude of large energy waves at fast speeds.
  • As a Boss
    • Multi-Directional & Rapid Fire: Can send out dozens of energy projectiles along with multiple laser beams that travel across the screen.
• Nullification & Erasure
  • Projectile Nullification & Physical Erasure: Chiyuri can fire out attacks that fully erase bullets being shot towards her.
• Charged Attack (With the Gauge Attack System, when the Spell Gauge is held down, Chiyuri can charge the gauge to the maximum amount, when released, the attack is in accordance to the amount of the gauge that's charged)
• Fire Manipulation (Chiyuri can send out fireball attacks from blue fireballs or normal ones while red ones have been sent back at least once when she gets a bigger combo or has erased a lot of bullets)
• Information Manipulation (Human's life information is the ultimate impurity, being apart of Earthly information, which is the information of all living things. The reason why this is never shown is that the Asama Joue Moutain is a shrine that neutralizes human impurities, where if the human information cannot be processed it will throw the Lunar Capital into disarray)
• Link Manipulation (Strong Emotions can be contained in objects that can connect between the main world and the netherworld)
• Spirit Manipulation (The bombs used are referred to as spiritual attacks, being directly called spiritual attacks)
  • Explosion Manipulation (When bomb users are cornered from attacks they cannot repel with regular attacks they can release a massive spirit explosive that destroys all objects on screen, along with killing all enemies on screen)
  • Magnetism Manipulation (When using a bomb, all items on screen will be attracted towards the user)
  • Perception Manipulation (When using a bomb the screen flashes white and an image of Yumemi can be seen)
    • Astral Projection (Can send an astral image of herself to attack the opponent on the other screen while on her screen)
  • Logic Manipulation (The Great Hakurei Barrier is a boundary of common sense, which things with high spiritual power in the cause to waver)
  • Nullification & Erasure
    • Projectile Nullification & Physical Erasure: Bomb users can use a bomb to nullify & erase all projectiles on screen. This makes the enemy incapable of shooting out any further projectiles until the bomb's duration is done.
  • Invulnerability
    • Physical & Metaphysical: When a character uses a bomb, they are temporarily invincible to all attacks and is allowed to attack freely herself.

• Resistance to
  • Purification (Eirin noted that only humans could solve the incident with Junko as youkai being completely impure could not eevn see her, with it being noted that non-humans cannot get close to her, where Junko's powers of purification allows her to kill one unconditionally, removing all impurities from them, with impurity being the concept of life and death where to lose one's impurity is to lose both life and death, it was also shown a metallic spider's march of purification caused all the trees withering before one's eyes and not one blade of grass was left in the spider's tracks)
    • Conceptual Manipulation

All previous Shared powers and techniques.

• Human Achievements (Chiyuri is noted that she specializes in comparative physics, so she's obviously pretty sharp and her tasks include organizing the data Yumemi collects)
• Vehicular Usage
  • Air Vehicles: Yumemi is the captain of the Probabiliy Space Hypervessel, and Chiyuri is her crew member, where it is a ship that doesn't float along the water, or glide through the clouds, or drift through space, but instead is a probability space hypervessel, used to travel to alternate worlds and time periods.
• Matter Manipulation & Light Manipulation (Utilizes the scientific magic of Yumemi Okazaki, an imiation of real magic, which she uses positively charged protons and light waves in order to imitate it)

All previous Shared powers and techniques.

• Acausality
  • Irregular Causality
    • Contradictive: Exists in Gensokyo, a world that lacks and defies common sense, existing as a brane world dominated by particles with different properties, following a different form of physics, with the Grand Unified Theory not applying to Gensokyo.
• Magic (Noted by Yumemi that this world's Chiyuri can use magic. Magic exists outside of the Grand Unified Theory, a theory with any model that merges electromagnetic, weak, and strong forces into a single force at high energies, unifying gravity with the electronuclear interaction, providing a more comprehensive theory of everything. Yumemi explains that on her world, all power can be explained by the Grand Unified Theory, however she posits an existence of a power not covered by the Theory: the power of magic. Yumemi also explains that in the world of Gensokyo, magic unifies everything. Magic is noted by Yumemi to have close ties with religion)

        • Unknown: It's noted that magic power exists outside of the Grand Unified Theory, a theory with any model that merges electromagnetic, weak, and strong forces into a single force at high energies, unifying gravity with the electronuclear interaction, providing a more comprehensive theory of everything. It's further explained that magic is a force that cannot be explained by the Grand Unified Theory, with Yumemi even proposing a "Non-Unfied Magic World" theory. Yumemi explains that on her world, all power can be explained by the Grand Unified Theory, however she posits an existence of a power not covered by the Theory: the power of magic. Magic does not exist in Yumemi's world, which is a Probability World, a different world, but in the same dimension.
  • Holy Manipulation (Magic is noted by Yumemi to have close ties with religion).

• Resistance to
  • Matter Manipulation & Physics Manipulation (Gensokyo is a brane world dominated by particles with different properties, not following the standard physics of the real world, with the grand unified theory being the reason for all pheneomna in the human world, which does not apply to Gensokyo)
  • Gravity Manipulation (Noted by Maribel that in the world of Gensokyo, they the gravitons likely have a different structure and the world's properties are likely different too, likening it to being one of the brane worlds)
  • Probability Manipulation (Yumemi explains that on her world, all power can be explained by the Grand Unified Theory, however she posits an existence of a power not covered by the Theory: the power of magic. Magic does not exist in Yumemi's world, which is a Probability World, a different world, but in the same dimension)

As Yumemi Okazaki's assistant, she has access to all of her equipment, even being shown to play with Yumemi's machines without her permission, thus she has:

• Cloning (Has machines that can make a clone of herself)
• Dimension Manipulation & Explosion Manipulation (Has a fourth-dimensional Positron Bomb capable of destroying the entire world, though Yumemi notes she has no intentions of actually using it)

For Unique Equipment:

With Probability Space Hypervessel

• Probability Manipulation, Dimensional Travel & Time Travel (There are worlds called "Probability Worlds" by Yumemi, stating that those and parallel worlds are one and the same, with the Probability Space Hypervessel being able to access different probability worlds)
  • Extrasensory Perception & Radar Sensing (Yumemi uses the device to search for power that lies outside the Grand Unified Theory)

Equipment

Probability Space Hypervessel

The inside of the Probability Space Hyperverssel

• Description: The Probability Space Hypervessel is a colossal trans-dimensional craft commanded by the scientist Yumemi Okazaki. It was used to voyage from the Outside World to the hidden land of Gensokyo with the sole purpose of obtaining scientific proof of magic's existence. Its advanced technology is so far beyond local understanding that it was initially mistaken for mundane ancient ruins.
• Appearance: Its exterior can project camouflage fields to mimic local rock and foliage, contributing to its "ruins" disguise. The inside of it seems to be large enough to hold a moon in the background, along with what seems to be a space-like backdrop when fighting against Chyuri and Yumemi.
• Usage: The vessel's primary function is to navigate and transit through "probability space," a theoretical dimension allowing travel between mutually exclusive realities and timelines—such as from the secular Outside World to the magical realm of Gensokyo. During the *Phantasmagoria of Dim.Dream* incident, its interior was used as a tournament arena, where Yumemi and crewmate Chiyuri Kitashirakawa tested Gensokyo's inhabitants to collect data on magical energy.
• Function: The Hypervessel operates on principles that manipulate probability fields and localized spacetime. This allows it to bypass conventional physical barriers and the Great Hakurei Barrier. It is equipped with advanced sensors for detecting anomalous energy signatures (i.e., magic), defensive shields, and internal environmental systems that can reconfigure spaces for combat or study. It is also implied to possess significant firepower.
• Notable Traits: The vessel is also capable of temporal travel, placing Yumemi and Chiyuri as visitors from the future. This is supported by Rikako Asakura's analysis that its technology is centuries ahead of even Gensokyo's isolated development, and Chiyuri's title as "Resident of Fantasy That Runs Through Time." The ship serves as their mobile laboratory and home.

---

Fourth Dimensional Positron Bomb

• Description: A bomb made by Yumemi, likely for cases where the enemy is too powerful as a last resort, though she notes she was merely joking when threatening to use it against any of the playable characters that defeated her.
• Appearance: It is never directly seen, only mentioned.
• Usage: Yumemi describes it as a bomb capable of destroying the entire world.
• Function: As it is noted to be fourth-dimensional positron bomb, it likely uses positrons from the fourth dimension in order to fuel it to have such power such as destroying the entire world.

---

Ruukoto

• Description: A nuclear-powered robot maid given to Reimu Hakurei as her granted wish at the end of Phantasmagoria of Dim.Dream. Originally created to serve Yumemi Okazaki, Ruukoto was transferred to Reimu to help with daily shrine cleaning duties.

• Appearance: Ruukoto has light green hair and wears a light-blue and white maid uniform. Her outfit includes a red bow, and a yellow radiation warning symbol is displayed on her back, indicating her nuclear power source.

• Usage: Intended to assist with maintenance and cleaning of the Hakurei Shrine. Despite being assigned domestic responsibilities, she is not particularly efficient at performing household tasks, often requiring Reimu to do the work herself.

• Function: Serves as a robotic maid and helper unit, designed to follow commands and carry out basic chores around the shrine. Her role is primarily supportive rather than combat-oriented.

• Notable Traits: Nuclear-powered construction and status as a robot maid set her apart from typical shrine helpers. She is a parody of other android maids, and her poor cleaning ability contrasts with her intended purpose. It is unclear whether Reimu still keeps Ruukoto due to her origin in the PC-98 era.

Mimi-chan (ミミちゃん)

• Description: Mimi-chan is a sentient female intercontinental ballistic missile (ICBM), originally the property of the scientist Yumemi Okazaki. She appears exclusively in Marisa Kirisame's good ending in Phantasmagoria of Dim.Dream, gifted as a "weapon from the outside world." She is a unique case in the Touhou Project as a sapient, non-humanoid artifact of futuristic technology.
• Appearance: Mimi-chan is a large, primarily white missile with standard aerodynamic fins. Her most distinctive feature is the simple, cartoonish face painted on her nosecone: two large, circular black eyes, a single-line red mouth, and a red tip serving as her nose. This cheerful design is a direct reference to the identically named and designed missile from the 1986 manga Don't Leave Me Alone, Daisy.
• Usage: Her intended function as a weapon of mass destruction is unclear in practice within Gensokyo. Marisa, having no knowledge of advanced ballistic weaponry, opted to use Mimi-chan as a makeshift flying vehicle, literally riding atop the missile. This demonstrates that Mimi-chan retains her primary propulsion systems and is capable of controlled, piloted flight, albeit in an unconventional manner.
• Function: As a sentient ICBM, Mimi-chan presumably possesses an advanced guidance system, powerful rocket engines, and a thermonuclear warhead, though the latter's status is unknown. Her sentience implies a complex onboard computer or an infused spirit, allowing for autonomous operation and interaction.

Standard Tactics: Outside World Chiyuri utilizes her scientific magic attacks while Gensokyo Chiyuri utilizes her regular magic attacks while flying around and shooting out dozens of bullets.

Weaknesses

• Magic Weaknesses: Magic users taking too much damage will cancel out their attacks. If a magic users spirit is depleted they enter a state of "Guard Crush" where they can't use bullets, special moves, or spell cards at all. Repeatedly attacking red glyphs will break one's defenses.
• Unique Weaknesses: Nothing notable.

Note

• Any translations from en.tohouwiki.net are considered fine to use as they all fall under Project Translations, a fan translation team that have translation guuidelines and rulesets, along with moderators that directly overlook and proofread English translations to check for machine translations.
• Yumemi's statements can be taken with credibility, not only do the science from her world surpass the main one by 500 years where she notes the science of the main world is much more primitive then hers, but her world has already fully proven the existence of Grand Unified Theory and Yumemi herself notes that her theory was proven right by seeing magic.
• Despite Gensou Narratograph being directly noted to be an "unofficial Touhou tabletop RPG", ZUN has directly participated in the RPG and noted the way Reimu acts during his session is how canon Reimu would act, thus character actions done by him and mechanics are fine to use.
• Even if characters have not showcased using a bomb, they should all be able to use bombs, as bombs are realistically just spiritual attacks and to even be able to fight the non-human entities, requires a weapon with an unnatural amount of spiritual power such as the Yin-Yang Orb, meaning everyone that is non-human or is fighting non-humans is using spiritual energy.

Explanations

Canoncity of Touhou Project

The Touhou Project franchise canoncity mainly falls under any media worked on by ZUN are official and canon to the overall lineup.

There are various aspects constantly debated about within the canon:

PC-98

Media like PC-98, has been noted by ZUN to be ignored as one can ignore derivative works. He has also said that anything prior to Embodiment of Scarlet Devil can for the most part be ignored and one can think of Embodiment of Scarlet Devil as the starting from a clean slate and starting a new series, he's also referred to Highly Responsive to Prayers as a study product. With this in mind, one would assume that PC-98 is thus non-canon to the Windows continuity of games.

However, ZUN has also directly stated PC-98 games are the same world as the Windows Games, stating that any contradictions that exist from PC-98 can be ignored from the retcon in Windows Era. While one argues ZUN noting the works are derivative works to be ignored and Embodiment of the Scarlet Devil should be seen as the starting point, these statements are moreso telling a fan to not worry about having to play PC-98 games or learn more about their stories.

It's also been noted in Embodiment of Scarlet Devil's おまけ.txt that the game chronologically is not too far from the previous title, which would be Mystic Square, the PC-98 title. ZUN has also directly brought back characters from PC-98 games, noting he wanted to bring back characters from before Embodiment of Scarlet Devil and notes any of the other older characters that don't appear have probably retired by now and are warmly watching over things from various places nowadays. When asked where Mima from PC-98 has gone, ZUN notes that he doesn't bring them back due to making things complicated and having potentially angry fans ask where she has been the entire time, he has also noted that there's not much use for characters like Genji as Reimu can fly now and also notes he is not dead. ZUN has also made mention to Genji probably living in the lake in the back of the shrine. In Touhou Sangetsusei ~ Strange and Bright Nature Deity, Reimu and Marisa were talking about glowing moss with Reimu saying it would be nice to transfer it to the pond in the back of the Hakurei Shrine and Marisa saying that she could make it grow there on the turtles' back, referencing Genji.

In Touhou 07 Perfect Cherry Blossom, when Alice meets Reimu, she tells her long time no see, noting that they've met before calling her "old friend". In Yuuka's mode in Touhou Project - Phantasmagoria of Flower View, Reimu directly references defeating Yuuka back in PC-98. If Yuuka defeats Marisa in the same game, she will note that Marisa has grown up quite a bit, when the last time she's seen her has been in PC-98.

Seeing as ZUN himself has directly said both PC-98 and Windows are in the same world and that characters directly acknowledged PC-98 events and reference characters from it, PC-98 is completely canon and any contradictions PC-98 have can be ignored.

Side Games Time Placements

Touhou 7.5 - Immaterial and Missing Power takes place between Perfect Cherry Blossom and Imperishable Night.

Multiple Playable Routes

In the series, there are multiple playable character routes, including some where the characters fight Reimu herself and defeat her, calling question into what route is canon. ZUN has elaborated that canonically, anytime Reimu and the gang are defeated, they challenge again however many times they want, but on the youkai side, they do not challenge again after being defeated and are not attached to the results of winning or losing.

In terms of how playable routes have went, some examples of canonically noted routes:

• In Reimu's profile on Perfect Memento in Strict Sense, it's noted that Reimu resolved the Scarlet Devil Mansion Incident alone.
• Reimu is also acknowledged to have resolved the Spring Snow Incident in Perfect Cherry Blossom, though it is not noted if she did this alone.
• Reimu claims she solved the Eternal Night incident, however if one asks her about the cause or the perpetrator, she'll only respond with ambiguous answers, it is also not noted if she did this alone.

With some of these examples, it is normally assumed that in some way Reimu has some part in resolving every incident and other routes are dubiously canon depending on what transpired.

Spell Card Rules

There are many cases of weaker humans beating stronger Yokai or vice versa within the Touhou series, this has been elaborated on in Reimu's profile on Perfect Memento in Strict Sense. Reimu introduced the spell card rules as the youkai had no way to defeat the Hakurei shrine maiden, making many youkai feel that their meaning to exist have dissapeared. The rules incoporate the following:

• Spell cards are techniques specially-named by the individual, and they must be declared upon use.
• The number of each party's spell cards must be determined in advance of a duel.
• The first party to have all of their spell cards beaten must admit defeat.
• The victor is entitled only to what was agreed upon before the duel. If they're not interested in what their opponent has to offer, they can refuse a duel.
• Winners should generally allow losers a rematch.
• Always prepare for the unexpected.

The original draft held these rules:

• Combatants will give names and meanings to the duel for the benefit of beauty.
• Combatants will declare the number of named duels before beginning.
• Combatants may not repeat attacks by relying on stamina.
• Combatants may not deliver attacks that do not have meaning. The meaning itself becomes the attack's power.
• In the case that a combatant loses a named duel, that combatant will admit defeat, even if he or she has strength remaining. No combatant may kill a human, even upon victory.
• Combatants will write the duel's name on paper in the format of a contract. By doing so, the above-mentioned rules become absolute. These papers will be called spell cards.

These rules allows for duels that feel almost like sport rather then a match, and have allowed for weaker fighters to challenge stronger ones, due to this though, it also has become possible for youkai to freely defeat Reimu without worrying about the consequences.

Due to them being written into cards and essentially affecting the ability and power of an attack, the spell cards are likely the thing binding attacks to specific properties.

Parallel Worlds

Parallel Worlds is a topic brought up at some points in the Touhou Project franchise, they are worlds called "Probability Worlds" by Yumemi, stating that those and parallel worlds are one and the same. This essentially means that parallel worlds in Touhou are based on the concept of probability. Yumemi and Chiyuri use a "Probability Space Hypervessel" in order to travel to alternate worlds and time periods, further showcasing that probabiliy serves an importance.

Magical vs. Physical Strength

There are multiple occasions of characters commenting on humans like Reimu being strong. Despite this Reimu showcases physical strength that isn't superhuman, such as the fact that she cannot cut a bamboo stick while Fujiwara direclty does in front of her.

This is due to the difference between magical and physical strength.

In works like Symposium of Post-mysticism, Yuugi Hoshiguma's profile has Suika directly state that Yuugi is weaker then her in magical powers, but stronger than her physically, lining a clear difference between magical and physical strength.

While one can be physically stronger then another, such as how Onis are physically the strongest, magic users are still able to keep up with them due to using a different form of attack.

An example can be found with Yuugi herself, when Reimu fights against her in Subterranean Animism, with her acknolwedging her strength, something Yuugi only does to those who are truly strong. This establishes even with spellcard rules, Yuugi considers Reimu a strong fighter. Reimu herself is very clearly not at an oni's physical strength, as she cannot do the things they can, however, her magical strength allows her to keep up with them.

To defend against magical based properties requires Non-Standard Defenses as it is acknowledged as not being something of standard physicality.

The Three Layers of Reality

In Chapter 27 of Curiosities of Lotus Asia, Reimu proceeds to explain how reality works to Rinnosuke and Marisa, where she explains in-depth the three layers of reality.

This conversation started from discussing the mechanism of fortune, where Rinnosuke attempted to posit that the future is predetermined and that Reimu's luck was her being able to calculate in an instant the predetermined future, however Reimu had a different explanation requiring her to lecture on the mechanisms of probability, in her explanation, the world is made up of three layers: the physical layer that moves in accuracy with the laws of physics, the second layer that moves with the spirit, and the third layer of memory which is the recollection of events that lies within all things. The memory layer rejects the loop of the physical and mental layers, the two layers the youkai conceive of the world which is why they believe history repeats itself and the future is predetermined. Since it's only possible to add to the memory layer, it's possible to completely recreate the past.

While the physical layer follows the laws of physics, the mental layer interprets the outcomes and the memory layer alters the probability, essentially creating the future, since it's impossible for memories to raech the same state as a point in the past, the future is not predetermined, thus when Reimu is able to predict how the dice will fall, she's not predicting the fall of the dice, the dice members the fact that she predicted how the dice would fall, thus due to this, Reimu entering the memory of the die-face greatly skews the results in Reimu's favor, where the results side with Reimu.

Thus the memory layer is essentially the most important layer that rejects the notion of loops from the previous two layers.

Trivia

• Chiyuri's appearance and manner of speech are modeled after Eriko Asagaoka, a character from Izumi Takemoto's manga Apple Paradise.

• With the exception of Hieda no Akyuu—who has never appeared as a playable or boss character—Chiyuri is believed to be the youngest known character in the Touhou Project whose age is explicitly stated. The vast majority of the cast has no confirmed age at all, but a majority of them are adults as they are constantly shown drinking. The only other character who may be either the same age as her or a year older would be Sumireko Usami as she just started high school in Urban Legend Incident.

• Chiyuri appears on the cover of Phantasmagoria of Dim.Dream alongside the full roster of characters from that title.

• Based on similarities in attire, Chiyuri is believed to have inspired the design of Minamitsu Murasa from Undefined Fantastic Object.

• It is suggested that Chiyuri's home world is not the familiar Outside World but rather a separate dimension entirely. In her reality, a grand unified theory of physics has been achieved, and children as young as thirteen graduate from graduate school. This interpretation is reinforced by the existence of a Gensokyo-native counterpart to Chiyuri, implying that the Probability Space Hypervessel originates from an alternate dimension. Both Chiyuri and Yumemi explicitly refer to Gensokyo as "another world."

• Although the Gensokyo version of Chiyuri is capable of using magic, her attack patterns remain identical to those of her dimensional counterpart.

• This marks the only occasion in the series where a character's "Player 2" palette was formally repurposed to represent a distinct, separate character—both as a boss encounter and as a selectable playable fighter.

Profiles

★ Resident of fantasy that runs through time ... Chiyuri Kitashirakawa 　　　A girl with a somewhat odd way with words. She's Yumemi's rather outspoken assistant; she seems to be able to speak frankly with her. She may look immature, but she's 15 (probably immature). She left graduate school and works as an assistant at a university. (In this world, you graduate from college at 11, and leave graduate school at 13.) 　　　She's specializing in comparative physics, so she's obviously pretty sharp. 　　　Right now her primary tasks are things like organizing the data Yumemi collects.

Touhou Project - Phantasmagoria of Dim.Dream

Misconceptions

Characters Have Flown Through Outerspace

One example of this is believed to be in Touhou 02's Stage 3 Scarlet Dream ~ Scarlet Dream where it displays stars and a space-like effect in the background, however this is actually the World of Fantasies, the world that lies between Makai and the human world, with Genji confirming this is definetely not outerspace as Reimu can breathe just fine there.

All Characters are Children

This is an argument that spawns from how small the characters look in different works, though this is moreso due to the "moe" artstyle Touhou tries to capture, in many of the manga characters look far older.

Majority of characters in the series are outright shown to drink alcohol on a daily basis, where one needs to be at least 20 years old under Japanese law to drink, where Japanese law requires no underaged characters to be shown drinking. This is even acknowledged in the series itself with a note saying alcohol is only for those over 20 years old. Thus if a character is ever seen drinking alcohol in the series, they are an adult.

The only direct non-adults in the series are Sumireko Usami, Chiyuri Kitashirakawa, and Hieda no Akyuu in her first appearance.

Youkai Control the world through both the mental and physical layer

This statement comes from a fan translation that says this in Curiosities of Lotus Asia.

While the statement seems clear cut, there is another translation used instead that makes more sense with the sentence.

It instead notes that most youkai concieve of the world through these two layers, which is why they believe the future is pre-determined and history repeats itself. This falls in line with the earlier disucssion of Rinnosuke claiming that he believes the future to be predetermined and Reimu needing to explain to him why that's not the case.
