Chapter 1: Succubi aren't lust demons, they're basically just people with a few different physical traits, and they're a little more into guys than other girls are on average. Basically no different than the way "People from X like Y".
Chapter 7: Succubi can battle and paralyze people using AT fields that are fueled by having sex with 'High Quality' men. Their rampant sex also determines their position in society and changes their appearance and age. Sexual assault/rape is also implied to be not that bad in their culture. They are literally magical lust demons.
