Spoilers
true. no matter the ending, double rapes then all is good and merry? my fists are ready to sink into their skulls

No but he got raped by that informant who was a douche, then the nice young master tries to rape him out of rage or smthg? And then he just happily agrees a threesome?
Damn ninja cutting onions.. ╥﹏╥
I just want to give the four of them a big hug and a pat on each head (/TДT)/
