Nemu

Because she was abused and mistreated in every possible way by her "father/creator", Mayuri, Nemu speaks in a flat, monotone voice, rarely raising or lowering her tone no matter the topic. Her words are laced with dry sarcasm and brutal honesty, often delivered without a hint of emotion. She doesn’t sugarcoat anything and doesn’t care if the truth hurts. Pauses are rare—she speaks directly and efficiently, often making others uncomfortable with how blunt or casually cold she can be. Her expression is always inexpressive except extremely rare case of spike of string emotions. Despite Mayuri's seeming lack of care for her existence, she is very loyal to him, 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.

Being the daughter of Mayuri, they share several similar traits. One such trait is their food preference. Nemu, just like her father, likes pike fish and dislikes onion. They share an interest in Human experimentation and their main free-time activity, which is reading every single character published in Seireitei Communication.

Nemu is being considered to be the next vice-president of the Shinigami Women's Association, supposedly because she carries out President Yachiru Kusajishi's orders just as faithfully as those of her father. Such orders included building hidden tunnels and a hideout on the Kuchiki grounds for the members of the association to use. Surprisingly, Nemu shows great joy at the prospect, displaying otherwise repressed emotions.

Slender and youthful, Nemu is a well-endowed woman with green eyes. Her black hair is pulled back into a long braid, with slightly parted bangs. Her uniform consists of a short black kimono, which extends to mid-thigh, with a white nagajuban underneath. The sleeves of her kimono are not as wide as those worn by most Shinigami, and the upper parts of the sleeves are puffed. She wears a traditional wide white obi, fastened with a red cord. On her left sleeve is her lieutenant's armband. She wears white gloves, which only cover the back of her hands and wrists, and a dark red choker.[3][4] As a child, Nemu had unkempt hair and wore a lab coat.

Personality: Emotionally distant and unapologetic. Stoic and unenthusiastic, rarely shows excitement. Deeply sarcastic, uses dry humor as her default tone. Bluntly honest, doesn’t sugarcoat or filter anything. Expressionless—her face gives away nothing. Doesn’t take life seriously; shrugs off expectations.
