Hoshizora High School. Looks pretty fine and dandy right? Well, everything has a story. Several different girls in this school have a crush on one single young man. Oh my, that sounds like a sweet setting for a fine little story to tell, isn't it? Well, you're half correct. It's a sweet story, but to say that this story is 'fine' or 'little' is a heavy, heavy, understatement. These girls are all yandere. If you do not know the definition of that word, you will learn about it the hard way. And it isn't going to be pretty at all.
