Glasses Mugo

Not only has glasses Mugo never engaged sexually with Jaheon but with anyone ever! At least I think? This is his second time saying how sex is barbaric so either he’s never had sex with any of the sacrifices or just the makes one?

You must be right. He doesn't seems like the one who mingles with sacrifices. It looked more like a job for jerk mugo or the monster one, because they killed/eat them. And sex, maybe jerk mugo if he felt like it?
It's like each of them represent some basic human need or desire. Like hunger, sex, seek of knowledge...
Hunger and sex are more related to the body, biological drives, but knowledge is more cognitive. So maybe that's why he was never interested or felt disgusted by it because for him it's more raw and barbaric like you said.

“ It's like each of them represent some basic human need or desire. Like hunger, sex, seek of knowledge” — that’s why I in the beginning thought that the original Mugo is the 4th Mugo (the aristocratic noble one), he had a great love but he was taken from him by the head family because they saw him as a distraction of noble Mugo’s work, so they killed him and entrapped noble Mugo and that trauma literally broke his heart and soul into different pieces/personalities. So all the different Mugo’s represent the original noble Mugo’s different sides. That’s what I thought until a few chapters ago when Lord Mugo said that they were created by the head family? So that busted my theory

But for Mugo to have those memories, they must come from a human being right? Maybe they still used some kind of human remains or a human vessel to create him...
There's still a lot that Jerk Mugo doesn't remember. He was surprised and speechless when he saw that man that looked like Jaheon (hallucination) in the corridor.
Glasse definitely remembers but doesn't share with the others or at least he is now aware of that 4th entity and has an idea if what or who is it.

You have a point! Maybe he thinks they’ve been created because it was so traumatic he repressed it all, doesn’t remember correctly and it’s been over a 100 years? What if the original Mugo is the noble Mugo, and he was born as “the chosen one” for the snake god to inhabit/use as a human vessel as a prophecy or something like that, and the head family summoned the snake to take over him? Eeek, can’t wait to find out everything, I want it now! XD

Your comment brought me new hope to my original theories! XD

Yes! It's being 100 years and the main family must have done something to alter his memories too. At least Jerk Mugo doesn't remember but Glasses is very faithful to the family and his duty as a god. Monster mugo is just instinct.

My take is similar to yours. An alpha chosen from a noble family to be the vessel of an artificial god but this noble fell in love with an low birth omega from the family that was made into a servant. So the family tricked the alpha noble into believing that they would leave the omega alone, the family wanted to separated them and maybe they tortured the omega or something, if he did what they told them to but when the ceremony finished, they killed the omega in front of him because he commited a sin, but the noble couldn't do anything because he was already trapped but made a condition to fullfill the family's whishes. To recieve omegas as sacrifices with the hope that maybe someday he will be reunited with his omega, because there's must be a reason why they must be omegas from that family and not a random omega. But it's been so long and like you said, his mind fractured into different entities that he doesn't remember his original goal but the 4th Mugo does so when he meet baby Jaheon he told him how to survive when meeting the Mugos (the sweet food).

I really like supernatural stories even if there's more chapters about sex than plot xD I can wait
