Tell me that a supernatural can never be human, that I should just give up!! You can't do anything about it anyway. You can at least stay in this world......and be here for me, as my friend. I get these scary thoughts. When I'm in that world, I get jealous. I start asking why i have to be like this. I wish everybody could be just like me. I wish they could all just die. See? Just like any supernatural. Ha ha...YOU'RE HUMAN! YOU COULD NEVER UNDERSTAND HOW I FEEL!!!
Mitsuba Sousuke used to attend Kamome Academy's middle-school division before he passed away in a car accident. Before his death, he had previously met Minamoto Kou. Sometime in the past, before entering Kamome, he was bullied for his girlish traits and cocky attitude—thus, he began to mask his personality, holding a passive, caring persona in order to make friends. However, this did not help him achieve his goal, and he mostly faded away into the background of his class and didn't form any close friendships while he was still alive. Due to his lifelong desire to have friends, his soul remained attached to the middle school following his death, haunting the locker rooms and often asking students if they remembered him. Kou confronted him once he was made aware, and together they tried to help Mitsuba fulfill his wish and pass on.
Mitsuba did not remember much from his past, only that he had held a camera that was donated to the photography club. It is later seen that he was part of the said club and often took pictures for the school albums, as noted by the pictures taken of Nene's gardening club. Nene remembers that he was a boy that won many awards for his photographs, but Mitsuba rarely brings it up. While he was still alive, Mitsuba was very close with his mother after his father passed away, though he often teased her for her appearance and style of clothing.
Mitsuba was first introduced through a rumor of a ghost that haunts the middle school lockers, grabbing people as they change their shoes and asking them "Do you remember me?". Kou caught him on the act when he grabbed his arm, and after consulting with Hanako, Kou decided to help him finish his unfinished business so he could move on from the world of the living.
Mitsuba appears after the disembodied hands dragged Nene into the 3rd School Mystery's boundary. The two progress through the Hell of Mirrors together and attempt to find a way to exit or find the Mystery's yorishiro. Mitsuba jeers at and teases Nene, but since she agrees to help him out and is nice to him, he seems to like her. After Tsukasa appears and defeats the Mystery, he attempts to force Mitsuba to consume its heart in order to become stronger. Mitsuba, clearly upset and scared by this, attempts to escape from Tsukasa until Nene tells Tsukasa to stop. Eventually, he does but end up consuming the heart, and assumes the role of the 3rd Mystery, gaining a new outfit and enhanced abilities.
When Kou and Hanako enter the area, Kou is shocked to see his former friend, and attempts to speak with him. However, Mitsuba does not remember Kou, and it is revealed that the Mitsuba in the Hell of Mirrors was created by Tsukasa from part of the old Mitsuba's soul. As a result, the new Mitsuba does not remember his life as a human or his time spent as a ghost. He does, however, have the same personality and even refers to Kou by the same mocking nickname as he did before. Tsukasa tells Mitsuba that he can do anything he wants as a school mystery, and so Mitsuba wishes to become a real human and live a normal life. However, Hanako dissuades him from this, since neither ghosts nor created supernaturals can be allowed to live as humans.
Mitsuba appears as a normal classmate of Kou's, as if his death back in his 2nd year had never happened.
Later, it's revealed that the fake world's version of Mitsuba is actually the one from the real world, having been brought to this world by Mei in order to grant his wish to live as a human. He reveals that he has seen everything that the old Mitsuba experienced, both in life and death, and is jealous of him. He believes that Kou is not actually his friend, and does not want to be. Kou disagrees, and says that he still wants to be his friend, going so far as to say the two could die together in order to prove it.
Alignment:Chaotic Neutral (Mitsuba's main wish is to become a human to fit in with everyone else and to make friends. He even goes as far as making a deal with Tsukasa to help the 4th wonder trap everyone in a fake world and have everyone’s memories erased so he can live his fake life. When Nene and Kou tried to find a way out, he wanted them to forget so he could stay there forever
When Kou was going to take that away from him, he said that he wished that everyone could die so he can finally make friends with everyone. He doesn’t actively want to kill anyone though This went so far that Kou tried to kill himself in order to make Mitsuba feel better. He saved Kou in the end and reluctantly allowed Kou free everyone from the fake world. He doesn't have an issue with siding with Tsukasa's team, but he always makes it a point that he is scared of all of them and doesn't agree with some of their practices)
Durability: At least Wall level, likely Higher (Should scale to the other School Wonders while they are outside of their boundaries. Should scale to Hanako, who as able to take hits from a Mermaid. Mitsuba was able to take hits from Hanako, who was able to cut a tree in half casually) | At least Room level, likely Higher (Should scale to Hanako, who was able to take hits from Teru Minamoto, who has similar strength as Hanako. Hanako has been seen to take kicks from Teru in his fights multiple times)
Intelligence: Extraordinary Genius (While Mitsuba doesn't like fighting, he is able to keep up in fights against Hanako or other supernaturals. This goes as far has helping Nene Yashiro come up with a plan to outsmart Hanako and force him to help destroy the fake world that Shijima Mei created)
Mitsuba has a scarf around his neck that serves to protect him at all costs. This scarf is able to help Mitsuba attack from a long distance and it can even protect him from attacks, even if he can't see them coming. These scarfs are also able to crush a person's soul and completely destroy large chunks of rock
Notable Techniques
None notable
Other
Standard Tactics:
Mitsuba doesn't particularly like fighting so he'll just try to brag about his cuteness. If he were forced to attack, Mitsuba would attack with his scarf to keep the opponents at a distance and crush their soul. As a last ditch effort, Mitsuba will drag you from your current location into another one and seal you in there
Weaknesses: If Mitsuba's Yorishiro gets destroyed, he becomes greatly weakened and will lose control of his boundary. Mitsuba is extremely scared of knives
Trivia
Mitsuba's favorite snack is flan pudding.
His biggest concern is that he can't build any muscles.
The 三 in Mitsuba means three, a reference to his position as No.3.
Though there are no official birthdays, Japanese fans celebrate March 28th as Mitsuba Day, as his name can also be read as 3, 2, 8.
His last name, Mitsuba, comes directly after Minamoto in alphabetical order (as exemplified by the class roster in the Picture Perfect arc) and in the *first term of their junior high year.
He's scared of lightning to the point of crying, but the remade Mitsuba believes Tsukasa is scarier.
Mitsuba's Japanese voice actor, Kobayashi Daiki, and stage actor, Mihara Daiki, both share the same first name.
