Enhanced brainsssss... BIG BRAIN!!!! His enhanced mind is bordering on being superhuman. But not quite there yet, since that would be ridiculous. And it would be hard for any author to correctly write a character possessing a superhuman mind.
so basically his breaking point is a girl getting killed? do realize how stupid that is. furthermore you painted him be a smart Mc, now when the a female involved you want to add emotions?
It's an interesting take on stats. I also like that the stats are small at this point. That'll probably change later since I see this has like 2000 chapters or so.
