底辺用務員復讐洗脳～ナマイキ令嬢催眠～

Aomisaka Academy, a storied and famous school attended only by the rich.
The protagonist, after getting fired from his previous job, finds himself working
as a lowly janitor at the school.
As a fat, middle-aged guy in his forties working at a high school,
he was naturally looked down upon by the elite student body.

Among such students, two girls were particularly harsh in their treatment of him. Asuka Sakura, the strict, and brilliant head of the disciplinary committee, and rich delinquent Reina Todo.
