Lamest outcome for me is that he lives, they profess thier love, what afterwards (relationship, marriage, etc...)What do you guys think Maya will do if she does in fact manage to save Mitsuomi. Do you think she will tell him she still has feelings for him. The dialogue mentioned something about the past being behind them and the infinte possibilites of the future.
I doubt that though, he's too far into his own beliefs to change. All of a sudden because he lived he's going to stop being the Ruler of the Takayanagi clan and Enforcement Tyrant, nope. I doubt even Maya can change him, or that she's willing to settle to his ways. Plus, I think she is in love with the old Mistoumi, not the new one. This is going to sound cruel but in a way, I think he is meant to die, this story would be really wierd without it, IMO.
