Kallen appeared in her world, in an alternative event of episode 6 of the second season, on a mission in her "Guren Nishki" to destroy a group of "Caerleon" battle ships until a group of "Sutherland" Knightmares appears. Kallen manages to defeat them all, but her "Guren"'s radiation surge wave arm was badly damaged, but also fell when the ship began to shake, which led Rakshata to send her unit to transform her "Guren Nishki" to the "Guren Kashōshiki". She later proceeds to destroy the other "Caerleon" along with Todoh in his "Zangetsu" Knightmare and encountered Suzaku in his "Lancelot" along with Gino in his "Tristan" and Anya in her "Mordred". Kallen had fought the three and defeated them, causing Suzaku to order a retreat to the Chinese Federation.
