Hokuto no Ken Episode 30, Destiny Lurks in the Shadows! Jagi, Who Are You? (宿命はしのびよる！ジャギお前は何者！！)

Official synopsis "You people! Say my name and see!" (Jagi). A man in an iron mask claims the name of Kenshiro and spreads terror from town to town. He is the one who once kidnapped Airi: Jagi, one of Kenshiro's three adoptive brothers. Master Ryūken, having had no sons, had taken in four adopted children. But Hokuto Shinken is passed down to a single successor, and it was to Kenshiro alone that the secrets were bequeathed. Consumed by resentment, Jagi tarnishes Kenshiro's name to draw him out of hiding. Entrusting Bat and Rin to Rei, Kenshiro walks toward the confrontation that fate has written.
