Kai Sampaguita

Though she is not initially involved in the street-fighting tournament Maki joins, Sampaguita Kai was one of her most difficult opponents. Using a similar fighting style to Maki, Kai faces her in a tag-team match during a women's wrestling tournament. She becomes obsessed, like a number of Maki's earlier opponents, with beating Maki. She's the younger sister of Lucha Master.
