Why must everyone focus on a Mokou without a Keine? I need to cleanse my palate, off to cute and fluffy MokouxKeine doujin!
Actually, what I'd love to see and am surprised nobody's done, is a scenario where Moukou waits for each successive rebirth of Keine, then spends another lifetime on and on through the ages. It makes sense since she already knows rebirth is a real thing via Akyuu and Komachi, and she literally has all the time in the world to wait.
Maybe someday.
