Kuroh isn't quite sad, but he's not quite the happiest person either. He's a junior detective and often wears an expressionless face while on the job, and most everyone else. Good luck getting to him to show who he really is.
K project, homra << litterally my favorite anime this year. I want to be a member of homra. Not bc of their powers or shit, but because I,ve never seen a solidarity like that. Their link are stronger and thicker than blood, it is amazing.
