You know what I’d like to see? A combination of Demi-chan and Monster Musume: Where the girls from Kimihito’s harem sit down with Takahashi and he asks them questions about their lives, their cultures.
Sure, we know a little bit about lamia, harpy, centaur, and mermaid culture, but we still know next to nothing about arachne, slimes, dullahans (though those two might be difficult because Suu doesn’t talk a whole lot and dullahans are supposedly extremely rare), zombies, ogres, cyclops, or dopplegangers.
