Homicide detective Hiroki Dan is the son of a former police superintendent general and seems to be on the fast track to career success. He maintains a hidden identity as a serial killer responsible for more than a hundred murders of people he deems beyond the reach of the law.
it's nice how he does what he does it's like tit for tat kind of thing the he gives exactly what the culprit deserves including his little own way doing good deeds.. overall till now it's good..
Its really enjoyable, the guy isn't a psychopath(well maybe a little, he just think what he's doing is good), just crazy and handsome, there is rape in it so watch out for that and it also doesn't seem like a Josei, only slight encounters between the other female so far. Can't wait for more, also there should be some tag like "something of justice" for these type of guys, I see them a lot in manga.
