At Night I Became a Monster by Yoru Sumino

Adachi has a secret every night he becomes monster roaming the town because what else is there to do? One night he encounters his classmate Yano the class punching bag so during the day. From that point on they form an uneasy friendship that's redistricted to the night. For though there is one monster at night there are many to face in the daylight.

One of the main points of this story is bullying and the different ways people participate. There are people who become immune to seeing someone constantly bullied if it keeps them safe. The people who will join in only if they have no choice and those that revel in it. Our main character is the kind that turns a blind eye. Playing a part so he doesn't get on the bad side of the people who enjoy the tormenting.

The other main part of the story is about finding the courage to be yourself. At school Adachi is exactly who he needs to be in order to fix in. Every action he makes every word out of his mouth is calculated. All of that changes when he gets to know Yano and when he starts to wonder if who he is as the monster is really who he is.

I highly recommend this book to anyone. It does touch on some tough subjects so use care as needed.
