Code Geass: Lelouch of the Rebellion

The Black Knights' assault on the Britannian Army in Narita proves successful and Cornelia is cornered by Kallen and Lelouch. At Euphemia's request, Suzaku rushes onto the battlefield in the Lancelot to rescue Cornelia. He saves her and manages to corner Lelouch. C.C. comes to his rescue by using her powers to mentally traumatize Suzaku. The Black Knights retreat from the conflict, leaving the Japan Liberation Front and the Britannian Army to fight among themselves. (Source: Wikipedia)
