Yeah. I'm not sure if Ganma can have kids, but it's an interesting situation. In my headcanon, Makoto actually has a Ganma body, Kanon did until she became/returned to Eyecon state, and now she's back to a human one. Ganma do have shorter "pregnancies" than humans do, so she's actually further on in her pregnancy than she'd be if Aran was human. If it came up, Aran would be very confused, because the child would have been born by now.
