After a fierce battle, Kallen manages to land a decisive blow on the "Lancelot"; however, this is at the cost of having her "Guren" completely disabled in the process and losing consciousness. While the "Lancelot" explodes, she falls from the floating fortress to what would have been her death had it not been for Gino's rescue. After the battle, she is taken along with many others who rebelled against Lelouch to execution, and then witnesses Lelouch's death by Suzaku disguised as Zero. She immediately understands what Lelouch has done, and stoutly proclaims that it is the real Zero with tears in her eyes.
