Isn't the masked dude in the last panel one of the people who were interested in Akira a long time ago, one of the same group of people as Aria? Seems like Akira might be destined to defeat at least one of them quite soon.
I like the idea of a manga subverting the "every girl wants to fuck the MC" trope by having every girl except the one the MC winds up with bait us into thinking she's fallen/going to fall for him only to friendzone (well, sonzone in this case) him.
