Airi is a character from Fist of the North Star and the beloved sister of Rei. While preparing for her impending marriage, she was kidnapped by a masked figure with seven scars on his chest and subsequently sold into slavery. Unable to fight back, she blinded herself to avoid seeing what had become of her as she gave in to the demands of her masters.
After being captured by the Fang Clan, Airi is used as bait against Rei, but the Fang Clan's plot is foiled by Kenshiro and Rei's combined efforts. Together, they manage to save Airi. Kenshiro subsequently manages to use his knowledge of Hokuto Shinken to restore Airi's vision, allowing her to see her brother's face once again.
