Q: How many cars does Touko own? And does she really have an ATV…?

Nasu: She’s a speed freak, that one. In her underground garage, she has four cars, two motorcycles, and what looks to be an honest-to-god reciprocating engine propeller plane. Of course, the original ending involved using that plane to escape after defeating the Demon God.
Takeuchi: Too bad we couldn’t use it. But hey, devils never cry, right?
