Code Geass: Lelouch of the Rebellion (2006)

S1E14 Geass vs. Geass

Lelouch suspects that Shirley might have figured out he is Zero, prompting him and C.C. to track her down in Narita. Meanwhile, Ohgi investigates the battlefield from the previous night and finds Villetta Nu, injured and left for dead. Lelouch then crosses paths with Mao, a young man who shares the Geass ability. Mao exploits his power to read minds, targeting Shirley's doubts and pushing her to shoot Lelouch. However, she hesitates at the critical moment, and C.C. manages to send Mao away temporarily. Overwhelmed by sorrow and guilt, Lelouch decides to use his Geass to wipe Shirley's memories of him.
