Airi

Rei's younger sister. On the day of her wedding, her parents were killed by Jagi and she was kidnapped and sold into slavery. She could not withstand the horrors she had witnessed and rendered herself blind by pouring poison into her eyes. The Fang Clan manage to steal her from her current owner and use her as a leverage against Rei, but she is saved through Rei and Kenshiro's combined efforts. After the Fang King is defeated, Kenshiro cures Airi of her blindness.
Due to Lin's bravery in the face of adversity against Ken-Oh's Invasion Squad, Airi becomes a strong and independent woman. She takes up arms against Gallon and his men, killing several of them armed with a crossbow. After Rei's death she remains at Mamiya's Village to look after her brother's grave.
