I really hated that the show was cancelled, but I started to come to like the show enough to watch the anime and then read the manga.
Protip: If you wanna watch this, READ THE MANGA. They sugarcoat a lot of shite about the characters in the anime, some for understandable reasons and some for pointless ones.
That aside, I really love this show. It incorporates everything I love about anime in a manner that is 10x better than how the big three did it: shady and funny asf anti-heroes, shy, no good protag, OP, superpowered fights, bishies, bishous, fights, oh my!
Just watch it.
