Yes, that's the reason I asked...

Typically, undead creatures are said to be immortal. And the MGE lore says that they all are restored and become increasingly more beautiful and powerful the more sex they have. Nothing suggest that they have a limited lifespan.

Magical Materials are objects. Objects don't grow or get old. Objects can become worn out or perish over time, but the MGE says that stuff like Living Armors become more durable than normal metal, Automatons are still fine after many thousands of years, and Living Dolls and Skeletons become restored when destroyed... everything suggests that they go on forever so long as they get SE...

So, since those two kinds of Mamono are potentially endless, their husbands should be too...
