The manga is about a female assassin. She is violin player and mostly use her gun/rifle/shotgun and her violin as weapon.
She becomes assasin for hire because her parents were killed when she was in high school, and she wants revenge. She trained in mountain with her mentor.
A very angst, real and dark manga about justice and revenge.

It was old manga, which illegaly published in my country by illegal publisher. The style is similar with Ikegami Ryoichi's. Since it's illegally published, the publisher didnt bother with the real title, character naming and such I couldnt find what its title. Here, it was published as Lady D.
In manga, she was referred as D (the assassin for hire), but I dont know if it' true or not because again they didnt care about such.

Anyone can help me find this manga? Would be very grateful.
Thank you
