I was just thinking the same thing
It's fiction, and part of the plot. Plus aren't they mafia and assassin? Real life much worse. That scene is just following the theme. So don't take it too personal.
I mean it’s just a reader’s preference—but also, just because it’s fiction doesn’t necessarily make it okay. Sometimes I come across stories that are so cool and I really enjoy them; however, rape happens to be apart of then, but it’s not necessarily adding anything to the plot which can sometimes be disappointing. Still a good story tho
he raped Kanata after he saw the hickeys, definitely no need for that in such a cool story.
