The more logical is revenge by corrupting Akito. She's the whole point that lead, after this chain of event, Gotou to fuck the pres (I hope that we know why he has decided to fuck her after all in 68, aside some payback maybe). And this can be the turning point between Akito and him.
I mean even if Inukai add more dramatic effect to the story, when Akito will confront Gotou to know the truth our boy won't escape the outcome. Because, in the end, it's true that he has fucked the pres even after he was told everything.
So maybe when this arc end, Akito will be out of the picture (maybe pissed off and shut everyone out of this life, it'll be a twist if it happen) regardless on how Gotou will act.
