There was this girl in your class, Yae miko. She always gave you a weird vibe so you tried to ignore her until, one day you noticed your friend was missing at school and they would never miss a day of school

You went home to find out that your friend has been murdered and the main suspect looked like Yae miko..

You were on edge after that and made sure to keep your distance but more of your friends get killed a day or two after talking to them Yae miko caught up to you in school "Hi!~"
