Kawashima is clearly the queen of his harem, then. Like Borte to Temujin/Genghis Khan. If anything changes about the nature of his 'harem', though, I suspect she'll still take priority, either through familiarity or her own insistence. She's been the most consistently-appearing female character in this.
Also, yes, ugly bastards being disgusting as a universal fact across all worlds. There's presumably a distinction between these and what our world calls 'bbw', I should hope. To be sure, I think most at least have a cute face, regardless of weight... but there's plenty out there that don't care, because any amount of fat equals vile and unfuckable to them. One guy in particular in comments for one Manwha I was reading that featured, among the characters, a cute, mildly plump shortstack, made it a point to tell me, when I responded to one of their misinformed comments relating to her love life in the story, that he'd rather wipe his ass with sandpaper. Again, she wasn't even all that fat, but some people are really shallow fucks.
For reference, it was called Sexercize, and the character in question was a side-character with her own side-plot separate from the main character(s), with only one of the supporting cast from the main plot involved in their plot, far as I can recall. Among all the characters, she was honestly the most attractive, to me, too. Was glad to see a cute shortstack in asian comics instead of just the usual supermodel-esque babes with like no body fat whatsoever. They seem to abhor giving any characters body fat when they still intend them to be likable. Only hip or boob (or thigh) fat allowed, or something.
