A middle schooler in class 1-2, he sits in the back of the classroom next to Takagi-san. He can't handle bitter things like black coffee, secretly enjoys the romance series 100% 𝘜𝘯𝘳𝘦𝘲𝘶𝘪𝘵𝘦𝘥 𝘓𝘰𝘷𝘦, and gets frightened very easily. Does average academically.
Naive and easily embarrassed, he quickly falls victim to Takagi-san's teasing, but his constant failure hasn't broken his drive to get back at her one day.
Though he dedicates considerable effort to devising plans to beat Takagi-san, his training and scheming never seem to achieve anything, and Takagi-san always appears to be one step ahead of him in every challenge he presents her with.
At some point he marries the now-former Takagi-san, having a daughter named Chi between them. After leaving school, he becomes a P.E. teacher, having continued his extensive physical training routines in his previous efforts to beat Takagi-san.
