Code Geass: Lelouch of the Rebellion (2006)

S02E10 When Shen Hu Wins Glory

Lelouch successfully escapes with the Empress Tianzi, and the Black Knights move to join forces with their Indian allies. Desperate to reclaim the Empress, the Eunuchs promise to forgive Li Xingke if he brings her back, granting him command of the formidable Shenhu. Kallen intercepts him in the upgraded Guren Flight-Enabled Version, but its power runs out and she's taken captive. Though Diethard urges retreat, Lelouch vows to save her. Xingke proves his tactical brilliance, forcing the Black Knights to take refuge at a mountainside monument—the tomb of the former Tianzi—hoping the Federation won't attack. The Eunuchs betray Xingke, calling in Britannian forces. Meanwhile, another Lelouch appears at Ashford Academy.
