Kurotsuchi, Nemu

涅ネム

Nemu serves as the lieutenant of the 12th Division within the Gotei 13, operating under Captain Mayuri Kurotsuchi.
Nemu is the artificially created daughter of Mayuri Kurotsuchi, resulting from his research into artificial bodies and artificial souls. This background has led her to become quite introverted and melancholic, often choosing silence in her captain's presence. Their dynamic differs significantly from a typical father-daughter relationship, as Mayuri appears indifferent to Nemu's well-being, even using her as bait in combat. The only positive note regarding him is that he has occasionally hinted at concern for her life, viewing it as a point of personal pride in his own skill as her creator. Despite enduring abuse and mistreatment in every conceivable way from her captain and father, Nemu remains deeply loyal to him and has openly voiced worry about the possibility of his death, likely stemming from an implied gratitude that Kurotsuchi brought her into existence. In contrast to her father, she seems to possess compassion for others, saving Uryū Ishida's life as thanks for sparing Mayuri. Judging by the 13th Squad episode endings and the Bount arc, Nemu's fighting style appears to combine capoeira-like martial arts with kidō attacks.
Nemu's body was engineered to withstand fatal injuries, although she still feels the pain associated with them. This resilience allows her to survive impregnation by Szayel Aporro Granz, a process intended to restore him to life while leaving his host as an empty husk. Mayuri can repair Nemu very quickly in such instances, enabling her to continue carrying out her father's orders. Nemu is also immune to many of Mayuri's poisons. Nevertheless, she carries a variety of antidotes for use at her discretion. She also stores various poisons and potions derived from Mayuri's research within her own body, making her highly dangerous to anyone who attacks her internally. Nemu does not typically carry a zanpakutō, but one is revealed in an illustration in the artbook "All Colour but the Black." Her zanpakutō takes the form of what appears to be a thin katana.
