What a fucking idiot MC. Killing yourself over 4000 times like this is so... INEFFECIENT. He's already living in 'babylon', is the fucking tower further than 24 hours away from him? He could run into the tower, get killed and then at the fucking least steal more powers as he goes further back in time. If he's resolved to literally committing suicide 4000 times, why the fuck wouldn't he just let someone else kill him? Hell, just walk up to every ranker and start a fight and make them kill you?
I mean, I get that he's supposed to be someone deeply unstable, or else he wouldn't have gotten such a power, but dang, boy. You stupid 'cause the writer wrote you dumb.
EDIT: He even fucking took breaks, he's a fucking idiot who doesn't even know what the fuck to do with his powers or how to synergise the slightest bit.
