Unchanged Man
This is psychological but not KS style. Theres no killing involved but it's very disturbing and horror feels. Like you're scared for what's gonna happen next. It's mystery too. The translations are not caught on to the raws, but the raws keep getting creepy and creepier
I hope this helps! (=・ω・=)
