Nemu Kurotsuchi

is lieutenant of the Twelfth Division of the Gotei 13 serving under Captain Mayuri Kurotsuchi.

Personality
Due to the fact that she was abused and mistreated in every possible way by her 'father', Mayuri, Nemu is a very shy, withdrawn, and introverted individual, preferring to stay silent in her captain's presence. Despite Mayuri's seemingly lack of care for her existence she is very loyal to him, to the point of willing to badly injure herself just to give him an advantage in battle. Unlike her father, however, she seems to have compassion for others, saving Uryū Ishida's life as thanks for not killing Mayuri.

Appearance
Petite and attractive she has purple hair with slightly parted bangs and pulled into a long braid. Her expression is almost always melancholic, it is rare to see her smile or any joy in her distinctive green eyes. Her uniform consists of a short black kimono with a white nagajuban under it. She wears a traditional wide white obi with a red cord fastening it. On her left sleeve is her lieutenant's armband. In addition she wears white gloves that cover only the back of her hands and wrists; as well as a red choker.

History
Little else is known about Nemu outside of the fact she is the artificially created "daughter" of Mayuri Kurotsuchi. While she is partly resistant to poisons she is still affected by Mayuri's zanpakutō, though it's non-fatal to her.

Soul Society Arc
Nemu is first seen alongside Mayuri during an interrogation of Ikkaku Madarame after losing to Ichigo Kurosaki. Though saying nothing, her father tells her to keep quiet prior to the two of them being intruded by Kenpachi Zaraki, also in search of Ichigo.

Hueco Mundo Arc
She is brought along by Mayuri to Hueco Mundo, invading the world with her father, Kenpachi, Unohana and Isane. Whilst there, she is one of the people who fights with Szayel Aporro Grantz, and is the one who is subjected to his 'Gabriel' ability, impregnating her and bursting out of her, reviving himself. However, a poison inside Nemu serves to enhance Szayel's state of mental perception to untold levels, to the point where one second feels like an eternity to him, and she is critical in bringing about his defeat. Mayuri then restores her- through questionable and quite possibly explicit means, given Mayuri's utterances and Renji and Uryuu's expressions- and orders her to open the door to Szayel's laboratory, wherein she, Mayuri, Uryuu and Renji discover bodies hanging from the ceiling.

Powers and Abilities
Enhanced Strength:

Hand to Hand Combat

Body Modification: Like his own body, Mayuri has implanted various modifications and chemicals within Nemu to use against his opponents. Nemu is mostly immune to the poisons used by Mayuri, including the deadly one used in his Bankai, as well as possesses within herself an augmentation chemical that ultimately does in Szayel Aporro Granz. It is also these modifications that allows Mayuri to revive her when she is in a death-like state.

Chemistry Knowledge: Though not as knowledgeable as her father, Nemu does know many things regarding the chemicals used by Mayuri in his work, enough to keep an antidote in case anyone becomes poisoned by him.

Zanpakutō
Not much is known about her zanpakutō as she usually doesn't carry it around, but she is revealed to have one in the illustration artbook All Color but the Black. Her zanpakutō's form appears to be a thin katana.
