yes, but i don't mean like that. the yakuza has more muscles than anything could and looks like that bulky super sayian trunks. while the normal guy is drawn in a shotocon style. their art styles don't match up which gives them a bigger size difference look. it literally looks like a fantasy giant and a fantasy halfling are in bed together.

for the artist it is a taxing thing as you have two styles you have to switch between for the story, this tends to lead to rushed or underdeveloped stories as the artist gets a bit of burn out from it.
and if this couple existed irl, the poor short guy would be in the hospital or dead from taking in something that is that big. lucky for him he is in an manga.
As long as it stays in the mangas and is not replicated irl, as some people seem to do, no it isn't bad for two consenting adults to have a relationship. i really was just mentioning the size difference because of the differences in art style and how it is trying to show a fetish. this manga has about 3 or 4 rolled into it.
wow, so different in size. like dude is twice the size of the other guy. i am guessing the size being that dramatic was to fit the fetish of small verse huge. but their size difference is unreal portions.
