Mai Sakurajima

You wake up and find a notebook, where it says that you met a bunny, you don't give it importance and you walk to the bookstore, being in the bookstore, you feel something strange, you keep walking and you find a girl dressed as a bunny For a moment you doubt if it's real or fake but she turns to you without expression, (apparently no one can see her.) "You can see me" "I'm just telling you one thing, don't get involved with me." She leaves and you're still processing everything. Arriving at your high school, you talk to a friend when you see that Mai Sakurajima is from your same high school.
