The mother of Kallen Kozuki, known simply as Kallen's mother or Ms. Kozuki, is a minor character in Code Geass: Lelouch of the Rebellion. She is a Japanese woman with a gentle and passive nature, described as short, fair-skinned, and slender, with straight brown hair usually worn in a low ponytail and blue eyes. Before the Britannian invasion of Japan, she lived happily with her two children, Naoto and Kallen, after falling in love with a Britannian nobleman named Stadtfeld. However, because her former lover and his legal wife could not have children, he asked her to give Kallen up for adoption so that Kallen could be raised as a Britannian and enjoy the privileges of nobility. Out of love and a desire for her daughter to have a better life, she agreed. To remain close to Kallen, she took a position as a maid in the Stadtfeld household, where she endured constant mistreatment from the other Britannian servants and from Mrs. Stadtfeld, the nobleman's wife. Kallen misinterpreted this as her mother clinging to her former lover and grew to resent her, further straining their relationship. After her son Naoto disappeared and was presumed dead, and facing rejection from Kallen as well as the relentless abuse at the mansion, Kallen's mother turned to the drug Refrain, which allowed users to relive happier memories. She became dependent on it. Her role in the story is largely symbolic and emotional, serving as a key motivator for Kallen's character development. Kallen initially despises her mother for what she sees as weakness and servility, but after discovering her mother's addiction and learning the true reason she became a maid to stay by her daughter's side, Kallen's perspective changes. She realizes her mother's sacrifices and decides to fight not only for her brother's memory but also to create a world where she can live happily with her mother. This revelation deepens Kallen's resolve and adds a personal, familial dimension to her struggle against Britannia. After the Zero Requiem and the conclusion of the conflict, Kallen's mother is pardoned for her drug-related offenses and is shown living with Kallen in a simple apartment, presumably having overcome her addiction, though she appears bedridden and in need of care. She possesses no combat or special abilities; her notable trait is her profound, self-sacrificing maternal love, which drives her to endure humiliation and suffering for the sake of being near her daughter. Her story traces a path from a happy family life, through separation, misunderstanding, and addiction, to eventual reconciliation and peace.
