水神 哲也

He is a student at St. Eichi Academy. His grades are in the upper-middle range, and he pretends to be an exemplary student, but in reality he is a perverted student who enjoys eavesdropping and voyeurism. One year has passed since he locked up his classmate Yurika Nishimura, a young lady, and took her virginity with an aphrodisiac he bought by mail order, completely training her to be his flesh slave. Now that he no longer feels freshness in her sexual acts towards him, he is seeking a new flesh slave. [From official site]
