One of Rantaro's sister, Sayuri is seven years old meets a fifthteen year old boy outside one day. Sayuri isn't really popular so she doesn't have many friends, one day she meets this boy who's the same age as her older brother Rantaro, the boy is short and has purple eyes. Her and the short boy become friends, Sayuri tells Rantaro about this boy.. when he finds out the boy is Kokichi he doesn't know how to react, him and Kokichi never really been on the best terms since Rantaro use to bully him. What will happen when Rantaro finds out his sister wants to invite Kokichi over?

Disclaimer: Keep in mind Sayuri isn't one of Rantaro's cannon siblings, this is just for this story.

Incase any of yall wanna know what Sayuri looks like she has long green hair (her hair is the same color as Rantaro's) she's about 4'5 and she usually wears her hair up in a ponytail and has bangs that she pushes to the side. Maybe one day I'll draw a picture of her so you guys can have a better repesentation of she looks like.

Also any photos or art in this book doesn't belong to me, unless I say it does!!
