Fuuta Okeya (桶屋 風太 Okeya Fūta) is the protagonist of Spirit Circle who discovers an age long feud between Kouko Ishigami and himself spread throughout his past lives. He has the ability to see ghosts and even communicate with them.Fone is the first of Okeya Fuuta's reincarnations that is introduced. He was born in the Yucatan peninsula during a primitive era, in a Mayan tribe that commits blood sacrifices.
Fone is chronologically Fuuta's second incarnation though. In this life, he and Rei were lovers until the tribe choose Rei to be the sacrifice next for the people. Kouko's incarnation of this time was the priestess name Stona who killed Rei during the ritual and Fone while he attempted to interrupt the ritual. Kouko's incarnation of this time killed him by slicing his head of with a sword.
Vann is chronologically Fuuta's third incarnation. In this life, he is a knight in training set out to become a knight in the Order. His mission is to kill the Raven Hair Witch (Medicine Woman) who was one of Kouko's reincarnation. When he met with her, he felt Fone's hatred deep inside his soul and stab the medicine woman in her guts. Before she died, she slam a hot rock into Vann's face and branded him with the birthmark that Fuuta has on his cheek in present time.
In his later years he finds an infant left by his door, and attempts to bring it to a church, hoping it would provide sanctuary for the babe. Instead the priest tells Vann to raise the child himself, and gives him some bread and sends him away. As he looks at the baby again, he subconsciously recognises the infant to be Rei, but only remembers the name. Seeing as the baby seemed to like the sound of the name, he decides to name her Rei. He cries, not knowing the reason for his tears.
He begins to work and raise Rei as his own, with some help from a farmwoman who helped provide goat's milk and taught him how to raise her. As Rei grows older, she asks what happened to her mother. Vann lies about her mother having passed away, and his lies become more elaborate with time. He spins tall tales about his past, claiming to have been a hero. His days with Rei comfort him more than drinking did and he lets go of his hate for the witch he killed many years earlier. He sells his sword to buy Rei new clothes and sets off with her to find her a husband. Rei recounts a dream where she was Rei from Fone's life, and that she was directed by God to go to Vann's side and comfort him. Vann cries at the story and thinks of how proud he is of Rei.
He travels back to his old home, the Flantyr holding, only to discover it had burnt down. On his way to find Cielo, a man he has decided would be a good husband to Rei, he strikes his head on a rock when he lost his footing just as they reach the village. As he lies dying, he wonders if deserved the happiness Rei brought him, he expresses his love for her and dies with no regrets.
