Psy-min Appli -Akumu no Netorare Game-

Kushida Touya attends a boarding school called Saimei Academy on a solitary island in the sea. One day, he receives an email saying he has qualified to participate in a hypnosis game which simultaneously installs a hypnosis app on his device. Although he tests the app on his sister and realizes it's real, Touya is hesitant to participate in the game that involves taking other people's apps until you are the last one remaining. However, when the student council president strips during a school assembly and claims to have no memory of why she did it, he suspects someone with the hypnosis app is responsible and decides to join the game to protect a girl he's close to.
