Lupin III: Part 6 Season 5 Episode 19

A 7.62mm Mirage

Lupin is "invited" by a psychotic millionaire named Zylberstein, one of his old acquaintances, to a solitary chess game for life and death. To increase the thrill, Zylberstein has hired an infamous female sniper named Mirage, a former partner of Jigen, to kill Lupin during the game. This results in a deadly hide-and-snipe match between Jigen and Mirage amidst a ruined mountain city, which ends when Jigen manages to critically damage Mirage's rifle just as she is taking aim at Lupin. The resulting ricochet hits Zylberstein instead. Lupin and Jigen discover the sniper is Mirage’s daughter, who took the job to finance her sick mother's transfer to a better hospital. Lupin leaves the monetary stake Zylberstein left him (in case Lupin won the game) to Mirage’s daughter, and Jigen dissuades her from pursuing a mercenary's life.
