Yuuko

Yuuko is the 20-year-old granddaughter of Jingoro, a former miner whose underground base becomes the center of a dangerous encounter with Cobra. When Cobra discovers her among the women held by the Pirate Guild, she initially appears to be one of their victims. Behind that appearance, however, Yuuko is far more alert and resourceful than she lets on. She secretly gathers information about the Guild's underground base and becomes an important source of help for Cobra as he attempts to escape their grasp.
