I just figured that Mamono live a long time (because dragons and ghosts and whatnot) and their husbands match their lifespan. And on the other hand some Mamono grow up incredibly fast but live normalish lifespans (Jinko, Lania, etc.)

I read one such hentai that was actually incredibly sweet and romantic about a guy who finds an abandoned toddler Lamia and she grows to marrying age in a couple of years.
