During the second battle of Tokyo, Kallen is rescued from captivity and returned to the "Guren" (complete with a pilot suit brought by Sayoko), which had been radically upgraded by Lloyd Asplund and Cécile Croomy during her imprisonment. Using the new "Guren", she annihilates the Britannian forces. Luciano Bradley and the Valkyrie squadron are killed, as are an untold number of support units. She then fights Suzaku, easily breaking through his defenses and bringing him to the brink of death. In doing so, however, she activates his Geass command, forcing him to survive by firing the "F.L.E.I.J.A." bomb. She dodges it and the bomb hits the government building, destroying a fair portion of the Tokyo Settlement.
