The Author's Note (Chp. 4 Pg. 32)
TL;DR: "My all ages work didn't do so hot, so now I'm making something edgy. If you think you're above that, well, you read this far anyways. Btw, this work is a shonen disguised as an edgefest"
The funny thing is he was apparently an assistant on Fairy Tail...
The last chapter had an author's note that his work might seem to be in poor taste, but he's only doing it to drum up interest. I thought it was nothing out of the ordinary until I got to the art where the MC is about to be molested. Someone tell Bobby that edge =/= quality.
