Manjusaka

Manjusaka is a short, beautiful and slender woman with shoulder-length red hair that has white strips while her hair hangs on the right side, red eyes with thin eyebrows and she has red polished nails.

She wears a black keyhole turtleneck under a short, indigo off-the-shoulder hanfu robe with a white trim. Over the robe, she wears a purple fur coat with diamond-shaped silver charms running down the sleeve. Her black leggings have a triangular cutout on the upper thigh and she wears white or pale blue platform boots with black soles. Manjusaka appears to fall in love easily since she claims affection for many people such as Black Bird, Green Phoenix and Seven. However, she can also be possessive of the people she likes. She became jealous of the Girl In White that Seven was close to, and killed her after he disappeared. She also tries to kill Seven, since he never returned her feelings and she didn't want him to be with somebody else that isn't her. She seems to enjoy beautiful things, to the point of calling Xiao Fei's transformed muscular appearance ugly. She also claims that she dislikes being violent, but is able to fight hand-to-hand using her metal fan as a knife.

Though Manjusaka is skilled at fighting, it seems like she prefers to use other people to do the fighting for her. She is shown to be very observant, and figures out Thirteen's connection to Blue Phoenix when she uses his technique and understands how Thirteen managed to take advantage of Black Bird's style and disarm him. It is possible that she is manipulative, as Black Bird's plan to kill Seven and give the reward to Manjusaka is unique compared to the slightly hostile interactions seen between other Shadow Killers.
