Kallen Kōzuki (紅月カレン Kōzuki Karen) is one of the main characters featured in Code Geass: Lelouch of the Rebellion, as well as one of the two protagonists of Code Geass: Lancelot & Guren. She is officially known as Kallen Stadtfeld. she wears a pink bunny outfit with bunny ears and pink heels when she works at Babel tower. She also uses a pistol. Kallen's general personality is that of a strong willed, determined, loyal and brave individual, who can also be quite short tempered and impulsive at times; She is also compassionate, quite sensitive and truly gentle to those she cares about, and has a strong sense of justice. While being presented as a cheerful kid through past pictures within her house, she doesn't show much of this side of her anymore within the show, being fully focused on the rebellion and her determination to take back what Britannia took from her and her people. This lead us to the reveal of Zero's identity when Suzaku is holding Zero at gunpoint in Kamine Island, Kallen is also there, aiming at Suzaku. Suzaku tells her she has the right to know and shoot at Zero’s mask, which breaks and reveals Lelouch’s face for his and Kallen's eyes to see. We then assist to Kallen's breakdown who totally falls apart, even on her knees by realizing the boy she despised and the leader she adored were one and the same. When she asks if he used Japanese as well as herself, Lelouch simply states that Japan would have been freed, just like she wanted and then fully focus his attention on Suzaku and on Nunnally having been abducted.
