For those of you who are not familiar with the character, Kallen is one of the primary characters to emerge out of the hugely popular blockbuster, two series long, Sunrise anime spectacular, Code Geass: Lelouch of the Rebellion. Kallen is half Britannian and half Japanese, or more accurately half Eleven, though she benefits hugely from her father’s Britannian heritage in that she is allowed to attend prestigious schools like Ashford Academy and generally doesn’t fall under the strict set of rules applied to normal Eleven citizens.
However, fiery-tempered and strong-willed Kallen leads somewhat of a double-life, eager to serve her Japanese heritage and more importantly to free her fellow countrymen. A crucial link in the resistance movement, Kallen is a skilled combatant, particularly when it comes to piloting Knightmare Frames and as the series progresses, she becomes ever more pivotal in Zero’s plan to defeat the hated Empire.
