White Flame - S1.E13

The White Haired Devil kidnaps Chiko, forcing Twenty Faces and Ken to chase after her and onto an airship. Meanwhile, the real Akechi appears and finds Akine, Tome, and Shunka bewildered but alive and well. After the Devil kills everyone on board the airship, she confronts Twenty Faces and reveals the past together as scientists and a project to create artificial bodies, which she had subjected herself to. While Ken attempts to disarm all the bombs the Devil has planted on the ship, Chiko manages to free herself and witnesses Twenty Faces finally put to rest the Devil.
