The action takes place in Euphorbia, the magical academy, which can enroll those who have outstanding magical potential.
People put high hopes on the main character Roy Brind, but his laziness led to the fact that the question arose about his exclusion.
Emily, Roy's classmate with high-class magic, refers to Roy as her servant and Diana, Emilia's older sister, and the Academy's chief director, ruled him out.
However, Roy receives a book of hypnosis and his (sexual) revenge against Emilia and Diana begins!
