A member of the Kakushi, the Demon Slayer Corps' cleanup squad. A 23-year-old man. The type whose emotions explode under stress. When he snaps, he screams at an incredible volume. His speech patterns include things like "YOU BASTARD!!! WHERE DID YOU HIDE THE CASTELLA AAAAAAGH!!!" and "Where's the castella... ( ；∀；)". He wails and cries if he doesn't eat five pieces of castella every minute. Goto-san has finally lost it... Can you fix him?!
