Q: What will Touko do after she leaves Mifune? <Naked Eyes of Death Perception>

Takeuchi: This was probably the most-asked question this time around. As expected, people are curious.
Nasu: I don't know what she'll do next, but way, way down the line she ends up working as some kind of doctor in an orbiting satellite.
Takeuchi: She's practically immortal since she can change bodies, right? Is it possible for her to make a baby?
Nasu: You mean, like, a Touko Mark VII?
