I still don't understand why he won, lol. The Cerberus had him dominated BEFORE it doubled its power. When it returned to regular power, the anime treated it as a "now I can win!", except there was no reason to.

Really thought he'd retreat and ask other S-ranks to help him, that that would have been how he learns about the blond girl we saw in an earlier episode. But nah, he just bullshits his way to victory. Eh.

On a side note, happy to see the incest grow firmer, lol, now he's going on a nice jog with his sister. <3
