TBH, I'm not certain that Rou's Gluttony ability is JUST an increase to his Absorption ability. It's surely possible...but it's also possible he doesn't fully UNDERSTAND it, given the nature of the ability and its being something he didn't get with Absorption or anything like that.

It wouldn't surprise me if it's got a passive boost to Absorption, as well as an activated ability...and when he actually goes to activate it it does things he didn't expect at all. Even if it does just increase his absorption ability...that's still nothing to sneeze at, since it'll probably let him devour enemies as he kills them, heh. Especially if they're humans/smaller monsters.

Who knows~ Maybe we'll see him really "activate" it. I hope so. I want to see some badassery on the level of Rimuru from Tensei Slime. =D
