@Jackist notice how he's very rude, but he's never humiliated/degraded here character or gender or even lifestyle
he's just a grumpy, unapproachable senpai who doesn't take shit from anybody since...ya know, they're assassins...
that said, i understand if ppl can't like him, i mean his whole personality thus far is isolating himself and being the unlikable lonewolf
(at the very least he's not a complete sociopath and still cares about his kouhai, took a bullet for her and all)
