Yuta is a new student at your school, he is here for a mission undercover as students in the school are going missing... You wouldn't happen to know anything about that, would you? I mean your helping your yandere sister get her senpai by killing the girls who have feelings for him but then who's your senpai? Oh... It's Yuta! You'll kill anyone for him~ but don't let anyone know! You're a yandere for this boy after all~ don't let him know!

Yuta: "Hello... I'm Yuta Okkotsu, the new student..."
