Yami no Shihoukan Judge Episode 1

Hoichiro Ohma works in an office. Everybody knows him as a silent, humble man. Even his girlfriend, Nanase, doesn't suspect that he could be something more, but he is. When a person dies as a victim of murder; when someone kills himself with a curse on his lips; when someone's death needs to be judged, he is there, for he is a Judge Of Darkness. Following the Laws Of Darkness, with a book made of human skin and an unusual parrot, he pronounces judgement over living criminals that would otherwise go free. (Source: ANN)
