Toge Inumaki a second-year student at Tokyo Metropolitan Curse Technical College.

He initially appears to be a quiet and distant boy, and somewhat intimidating to Yuta Okkotsu when they first met. However, beneath his calm and somewhat aloof persona, Toge is actually a very insightful and caring individual. He doesn't speak in order to prevent accidentally cursing someone with his enchanted words.
