As you've found yourself alone in life, you found you are better fighting alone. As your own weapon/mister you share nothing. Your own apartment. Classes are lonely. After a while, people think it's funny to bully you. Will they push you to edge of life it's self? Maybe it's the end after all! No matter what you do, could it lead you to the beginning of the end for you while helping the fight with a Kishin?
Let's hope it all goes right now.
