His cheat is called "infinite enhancement". He gets a finite number of points, which he can use to upgrade an item a finite amount of times. Seriously, all he can do is upgrade stuff, and this is the only SSS rank talent ever? I'd call that S rank, at best.Also, he, despite being strong enough to fight on his own, and previously rejecting anyone wanting him to join, allows two girls to fight with him as harem members - oh, sorry, I mean, "support" people. And his giving them a bunch of enhanced items is totally logical.I mean I'm sure he would also help his male contemporaries if they didn't all turn out to be evil greedy thieving murderers.
