As described by a friend of mine:
This is just a generic battle shounen manga where nobody dies and everyone is protected by shounen cliches! And obviously the protagonist has shounen protagonist swag, like a harem (so all the girls in the harem are automatically protected by the plot). The series title is a lie.
This manga is meant to make you feel all warm inside, and show you that with friends by your side, you can overcome anything! ANYTHING!
You should totally read it
