OVA
Description
Kallen Stadtfeld, who also uses the name Kallen Kouzuki, is reimagined in the role of the March Hare within the fantastical setting of Code Geass: Nunnally in Wonderland. Her background is rooted in her identity as a young woman of Britannian and Japanese heritage. In the primary narrative, she is a student at Ashford Academy who secretly serves as a formidable soldier and the ace pilot of the resistance group known as the Black Knights. For her role in this story, she adopts the characteristics of the March Hare, a famously erratic and impulsive denizen of Wonderland.

Her personality in this role captures the energetic and volatile essence of the March Hare. Known for her strong will and short temper in her original portrayal, Kallen channels these traits into a more chaotic and aggressive demeanor, befitting a creature known for its unpredictable nature. She is forceful, impulsive, and not one to back down from a confrontation. This spirited and feisty attitude is on full display, as she readily engages in a dispute over territory and status, determined to assert her position.

Her primary motivation within the story of Nunnally in Wonderland is tied to her role as the March Hare, which is to participate in the mad tea party and its surrounding absurd conflicts. When Nunnally finds herself at the White Rabbit's house, Kallen, as the March Hare, storms in, demanding to know the source of a disturbance. This triggers a rivalry to determine who should be the sole rabbit in the forest, leading her to challenge the White Rabbit. Her actions inadvertently cause Nunnally to leave, which then becomes a point of contention with the Mad Hatter, driving the group to realize their host is missing.

Key relationships are defined by the characters' Wonderland counterparts. Her most direct relationship is with Anya Alstreim, who plays the White Rabbit. The two come into immediate conflict, engaging in a fight to establish dominance. She is also part of the ensemble that includes the Mad Hatter, the Duchess, the Cook, and the Dormouse, forming the core group of eccentric characters Nunnally encounters. While her loyalties from the main series are translated into this new context, her fierce and protective nature remains a core part of her interpretation.

There is no documented character arc or significant personal change for Kallen within the events of Nunnally in Wonderland beyond fulfilling her role as the March Hare.
