Sensei wa Egoist

A high school setting features several attractive male teachers involved in personal, after-school lessons with a student named Yume. One of them, an English teacher, initially appears charming but is later revealed to be a sadist who has influenced Yume to adopt a submissive personality. He manipulates her through escalating commands and praise. Additional teachers, including a chemistry instructor with a sinister demeanor and a history teacher with a deceptive smile and glasses, also play roles in these private interactions. The series consists of four stories, including *Sensei wa Egotist*, *Sensei no Koibito*, *Sensei no Kai Neko*, and *Sensei wa Egotist in Natsuyasum*, all illustrated by Nana-chan.
