1x10 - Code Geass: Lelouch of the Rebellion

Cornelia and the Britannian Army heads to Narita, hoping to destroy the remnants of the Japan Liberation Front. Lelouch has his Knights follow her in the hope of capturing her alive so he can question her about his mother's death. As the Britannian forces close in on the Front's headquarters, Kallen utilizes her new Knightmare Frame, the Guren Mk-II, to cause a massive landslide that takes out much of the Britannian forces.
