This manga is somewhat messed up. The main character's name is Kaname Aizawa and he has a fricked up home life, so he always thinks about killing himself. He goes through everyday having these thoughts and doesn't really hang out with anyone. He is walking in the school hallways when he accidentally knocks into Shiina Hinami. Both of their books scatter on the ground and Kaname picks up Shiina's notebook. He opens it and is surprised to find out she has written down bad things. Like, "I want to commit suicide" things. For some reason, he agrees to follow her to a torn down elementary school. Kaname finds out Shiina uses this place to cut up and murder animals, so that's pretty cool. Throughout the story, we. find out that Shiina doesn't really have the worst home life, so I don't know why she wants to kill herself. We are introduced to other characters such as Kaname's ex-girlfriend. She also has a fricked up home life. Her father sexually abuses her daily and she doesn't report him because she thinks its her only was to be useful. The story never really appealed to me and they either don't explain and have very bad explanations of why various events occur. Hopefully it will get better after more translated chapters come out.
