Much like Takumi, Shinnosuke is really a Roidmude who thinks he's human. Kiriko has said that she can't become Drive. Mr. Belt has said that Shinnosuke is "irreplaceable". Proto-Drive was almost certainly Chase, who is also Roidmude 000 and the only known human-type Roidmude. The logical conclusion is that only human-type Roidmudes can become Drive, and the only two in existence are Chase and Shinnosuke. The real Shinnosuke Tomari died a long time ago, and the one we see in the series is a Roidmude who took his form and subsequently lost his memories. To mirror Chase being Roidmude 000, Shinnosuke is Roidmude 108.
