Cant remember name manga!?
I can't remember the name of the series, its on onemanga, it is about a vampire who's daughter (human mother) shows up at his house after her mother dies, the vampire know a detective or something and i think he drink the blood of a criminal, that is all I can remember.
no it was definitely on onemanga, but it might only go by the English translation or alternate title on OM, do you know any?
