The backstories are quite well done and they're all well-written. While the emotionless and terrible mental state of Yu is a core theme, it's hardly built upon, and is merely used a prop. Also the protagonist being extremely OP and his mind being such a black box sort of takes away from any suspense or impact the fight has.
Also this is just a personal gripe but I really hate that K as a villain has no level of repercussions - it seems he just gets away with everything. My biggest issues are just that Yu's mind isn't really explored and K was never given any consequences.
Overall 7/10, the art is great and the story is good.
