- Determinator: He absolutely won't give up.
- Hot-Blooded: He's rash and hot-headed, which has caused a fair amount of trouble for the SDS. He does get better as time goes on.
- Oblivious to Love: Has no idea Marimari has feelings for him.
- The Unchosen One: It turns out that Keisaku was the one AHRV foresaw being the most important person in the Shibuya Drift and thus selected to be the first one to man a string puppet, with Daisuke only being considered a backup. However, due to Prophecy Twist, that wound up getting turned on its head.
- Action Girl: As is the standard for AHRV agents.
- Badass Biker: Rides a motorcycle around the wasteland.
- Screw Destiny: Comes to believe this to an extent, thanks to Daisuke's actions and refusal to let Keisaku be sacrificed in the past.
