It’s canon that shalltear is bisexual, necrophilic and has 100% definitely had sex with at least one man seeing as how she can ride a bicorn (she made fun of albedo for not being able to). again, its also a well known fact that she turns brain into a sex slave in the WN. You cleverly ignored that point though.

The only canon people who actively love Ainz are shalltear (because she’s a necrophiliac and for similar reasons hits on Yuri Alpha as well), albedo (because Ainz edited her settings) and possibly Zesshi since she wants to have children with the most powerful person she can find (though since Ainz is a skeleton she might go for Demiurge or Mare (when he’s older) instead).

Literally no one else has shown romantic or sexual interest in Ainz.

Bro I’m not even saying that there’s no fan service, there 100% is. Shalltear and Albedo’s entire existences are p much one big ball of fan service. I’m just saying that the only “pure” people are Albedo and Aura (a child so..) and that he doesn’t have that many people after him.
