Kallen Stadtfeld, also known as Kallen Kouzuki, is a prominent character in the anime series “Code Geass: Hangyaku no Lelouch”. She has a strong-willed and determined personality, often displaying loyalty and bravery in her actions. Kallen is known for her short temper and forceful nature, and sometimes acts impulsively. Beneath her uncompromising exterior, however, she reveals a sensitive, compassionate, and genuinely gentle side.
Despite her dual British and Japanese heritage, Kallen identifies strongly with her Japanese roots. She refuses to fully embrace her Britannian side because it would mean abandoning her Japanese friends, people, and her true self. This selflessness makes her one of the few characters on the show who puts the welfare of others ahead of personal gain. Although she initially claims to hate the British, Kallen’s compassionate nature extends to caring for British civilians on several occasions.
At Ashford Academy, Kallen hides her true identity to avoid suspicion. She adopts a different hairstyle and alters her true personality while at school. In her day-to-day life, Kallen is strong and confident, with a strong affinity for her Japanese heritage. At school, however, she assumes a meek and withdrawn persona to hide her involvement with the Black Knights, a resistance group.


Kallen Stadtfeld is a young woman of Anglo-Japanese descent. She considers herself Japanese at heart and prefers her mother’s Japanese maiden name. Kallen’s mother, an Eleven, stayed with her and her siblings for most of their lives. Her older brother, Naoto Kouzuki, led a resistance organization before his untimely death. After his death, Kallen joined the same guerrilla resistance group that later evolved into the Order of the Black Knights under the leadership of Lelouch vi Britannia.
Kallen’s father is a Britannian noble from a distinguished family. Since his legal wife, Lady Stadtfeld, was unable to bear children, he requested that Kallen be formally adopted into her household as his heir. Despite Kallen’s disapproval, her mother, Ms. Kouzuki, accepted the request to ensure that her daughter would benefit from being a Britannian noble. Unbeknownst to Kallen at the time, her biological mother fought against the mistreatment she suffered at the hands of Kallen’s stepmother and other pure Britannian maids. Ms. Kouzuki even worked as a maid in the Stadtfeld household in order to stay by Kallen’s side.


Kallen Stadtfeld has a striking appearance that reflects her mixed heritage. She is often recognized by her bright red hair and captivating green eyes. Standing at a height of 171 cm (5’7″), Kallen cuts an imposing figure. Her physical attributes, combined with her confident demeanor, contribute to her powerful presence.
In the series, Kallen wears different outfits depending on the context. At school, she disguises herself as a frail and withdrawn girl and wears a more conservative and modest outfit. Conversely, during her activities with the Black Knights, she wears a pilot’s suit while operating Knightmare Frames, powerful mecha units used in combat.

Her expertise lies in piloting the Glasgow/Burai (Custom Red), Guren Mk-II, Guren Flight-Enabled Version, and Guren S.E.I.T.E.N. Eight Elements Knightmare frames.
