However, with the demon lord defeated by some other human, their reason for existing is in doubt.

A haughty girl that thinks angels are superior to everything.

Is quite lusty.

Lucile

Before his memory loss, he was already a masochist for demon punishment...

She loves big, older men though, so maybe it's not all bad.
