Airi

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.
