That was jerk mugo the whole time. All 3 of them are lord mugo, just different personas, so it's not wrong of Jerk mugo to say he was referring to himself.
but don't they usually treat themselves like separate identities? idk it was just suspicious, but i could gen be wrong
Earlier on in the story kind mugo said "they're all me". It was weird I agree because jerk mugo usually differentiates himself from kind mugo but that doesn't mean he doesn't understand they're the same person/host
"idk I'm on to absolutely nothing" LMAO that made me chuckle
The way "jerk" mugo slipped up and referred to lord mugo has himself. So would this mean that lord mugo was the one who took care of the mc's heat, but was also deceiving the mc by acting like the jerk. Idk i'm on to absolutely nothing
