Character Outline[]


Kallen's Mother waving goodbye.

A Japanese woman who fell in love with a Britannian of the name Stadtfeld, who was a nobleman. With him she had two children, Kallen and Naoto Kōzuki. The children stayed with their mother for most of their lives.

Since his legal wife, Mrs. Stadtfeld, could not bear any children, Mr. Stadtfeld requested Ms. Kōzuki to formally adopt Kallen into his household as his heir. Since Kallen would benefit from being a Britannian noble, Ms. Kōzuki accepted Mr. Stadtfeld's request without Kallen's consent.


Though Stadtfeld's wife ordered Kallen's mother never to see her daughter again, Ms. Kōzuki refused. Determined to remain by her daughter's side no matter what, she fought hard to be hired as a maid in the Stadtfelds' household.

Ms. Kōzuki endured a great deal of abuse from Kallen's stepmother and the other maids, who were all pure Britannians. Though Kallen would try to discreetly help her, their relationship became very strained and Kallen usually stayed away from her mother, under the mistaken belief that she did it all to be with her father. When she could no longer bear her miserable life at the Stadtfeld house, Ms. Kōzuki turned to Refrain to recall happier moments in the past. She is eventually arrested and sentenced to 20 years in prison for using Refrain, though the incident led to Kallen learning that her mother resorted to using drugs managed to bring them back together, as Kallen realized that Mrs. Kōzuki actually became the maid of the Stadtfeld family to be with her.

Kallen's mother is not seen again until the final episode of the second season where she is shown to have been freed, dropped of all charges, and living a normal life with Kallen in a rather simple apartment. She is presumed to have overcome her Refrain addiction, but seems to be bedriodden. She is last seen drinking tea and waving goodbye to Kallen departing for school.
