Sasha Song

"I taught you all I could. I managed to grab a hold of a scared, damaged little child, and turn you to a powerful, fierce monster. But, above all else, I've removed conscience from you. There is no more weakness left in you. Now...make me proud."

- Songbird ccomplimenting Sasha at the end of her training Sasha Song (サシャソング, Sasha Songu) is a contract killer located in Bosco, working under Songbird, who essentially raised her after saving her from her life as a slave, along with many more children, back when Grigori was still alive. She is considered his right-hand woman, his most trusted and loyal killer, causing her to be addressed as The Bird's Monster 鳥の化け物, Tori no Bakemono).

Much like Songbird, Sasha is also a broker, though her work is evidently much more centered around killing assigned targets and following Songbird's orders, as opposed to black market buisness, and tends to go under the alias of Crow (クロウ, Kurō), as her broker persona, while going under the guise of Songbird's employee at his pet shop when not killing people for money, or selling illegal merchandise.

Trivia

 * It is confirmed that Sasha views Songbird very much like a father, as he practically raised her, and even gave her a new name.
