Owari No Yandere!(mikayuu)

Yuu and his friends shinoa, yoichi and mitsuba go to this new school called 'owari high'. They thought they'd just go to a new boring school and nothing would happen, but they thought wrong. Instead of their boring school work and learning, they go through tough times trying to find this 'yandere' to save their school from everyone being killed! Who is this yandere?...

Word: A Yandere is a person(girl or boy) that Will fall in love with someone and become obsessed with that person to the point of killing people who get near that person or even killing the one they love so no one else can have them.
