大友 隆介

A student at a private, F-rank university, he has recently been hired by the Ichinose family as a part-time tutor. However, he is made fun of by his student Azusa and disliked by her mother, Sakiko, and gradually grows resentful of the two. He borrows an accessory-type hypnotic sound wave receiver and remote control from a senior student at his university for monitoring tests. In his frustration, he plans to use it to play a mild prank on the family where he works part-time. [From Official website]
