The Daughter of Twenty Faces - Season 1 Episode 2 East Crimson Evening

Chizuko, now nicknamed "Chiko", is introduced to the rest of thieves, who gradually warm up to her and her determination not to be a hinderance. The group is forced to abandon when the police, who were following the airship, arrive at the island. They flee to an Asian country and are betrayed by Chen, a man who sells information to thieves for money, but manage to escape with the treasure anyway. On the way back, Twenty Faces is shot and they are forced to take refuge in a woman's house until they can get a hold of the other members of the band. Chiko is left alone with Twenty Faces until Ken and Skipper get back. She discovers that the woman was planning on selling Twenty Faces to a group of bounty hunters and ultimately foil her plans, successfully returning to the base with the treasure.
