You know what I like about this series?
In every shounen anime or manga, there is a moment where things seem hopeless, darkness sets in and the MC gives into his darker feelings. It often comes with incredible power.
Gon vs cat girl.
Super Saiyan.
etc, etc, etc.
The problem is, in all those series it lasts maybe two or three chapters before the power of LOVE AND FRIENDSHIP makes them go back to normal.
Not this series, this motherfucker went completely bat shit insane and has stayed that way for like 30 chapters. Hell, he gets worse every chapter.
I like that.
