三城 刀輝

Touki has the qualities of a Saniwa, a person who judges which god or spirit has taken possession of a miko (Shinto). Because this quality, he can be a vessel for any spirit like Magatsumi, Ayase, or rakshasa (a type of evil spirit). But Rakshasa are a special spirit exclusive for Kamiizumi Family, and since Touki has a blood relative with the Kamiizumi Family, he can awaken Rakshasa's blood. This Rakshasa's blood is the cause for his trauma against forging katana, and feelings of guilt towards murdering his childhood friend. He also possesses the qualities of a warrior (戦人), tailoring to a high combat effectiveness.
