Daichi Kitaumekawa

Daichi Kitaumekawa is Satou Matsuzaka's teacher who is renowned for his good looks and nice personality among his students. However, underneath this facade lies a deeply perverted man who takes an interest in Satou, obsessing over her after a school event.

At school, Daichi is considered to be a kind and helpful teacher who demonstrates his concern for his students by speaking to them privately about personal matters and offering assistance in any way he can.
