I think the manga is better but its reeallllyyy good. Well, i like it. a lot d:
He does go on angry rampages actually, just not lately. see the first line of his personality says:
the thing is, nothing but shiro has made him angry because he only gets angry is something he protects is under threat. d: so as soon as someone makes a stab at Marisa, he's gonna be like "oh god YOU DID NOT JUST SAY THAT OK FIGHT ME NOW!"
i realised everyone made their characters so edgey and crazy. i like to keep mine with quirks, but not completely out of control haha.
