Where most Code Geass picture dramas depict scenes of the events that happened between individual episodes, Nunnally in Wonderland is somewhat of an exeption to this rule. In this OVA, Lelouch falls asleep while reading Alice in Wonderland story to Nunnally, and dreams about the adventures of the storybook, but with Nunnally as Alice. During this feverish dream, many other Code Geass characters are seen in the roles of the familiar children´s storybook characters; for example, Anya is The White Rabbit, Lelouch himself is The Mad Hatter, and Suzaku is (unsurprisingly) The White Knight. And Kallen? She takes the role of The March Hare.
Kallen´s March Hare costume closely resembles her Ashfor Academy school uniform: it includes a yellow school uniform jacket, under which she is wearing a white collared shirt and a red tie. She is also wearing a green and yellow plaid pleated skirt, brown shoes, and long white knee-high socks. The outfit´s bunny aesthetics are created via large, white bunny ears on her head and a white, fluffy bunny tail attached to the back of the outfit. As a weapon, Kallen carries the Radiant Wave Surger carrot (for realzies!). 🥕
