So uh, what's even the downsides of a yuki-onna here. She cries ice? Looks good for her age? The unusually snow-white hair? The (probably) dressing lightly in colder climates (maybe? She's okay with hot springs so iunno).
The ex-husbands already got to the point of marriage and raw-dogging them without frostbite. Yuki-onna children aren't even gender locked, it's just boys are probably SSR gacha rates.
The Succubus kill you at least, but the yuki-onna are just white women. What's the problem here?
