After Leon finds out his death was ordered by some of his relatives because he hunted the Phoenix and got its much-coveted blood, he runs away with her and reaches an organ-smuggling crime headquarters. The female leader of the operations falls in love with Leon, who rejects her, and she decides to forcefully combine her body with his by surgery of a mad scientist working for her, Dr. Weekday. After a last request by Leon on Weekday, he agrees to load his mind into Chihiro... but the girl-robot does not have enough memory space in her body. Weekday combines them into a bigger robot. Leon-Chihiro gradually forgets his/her memories and runs away, being taken in by a family, who enjoys his/her gentleness, knowledge of human games and trustworthiness. Leon-Chihiro is then copied and mass-produced worldwide, as popular household and nanny robots. His/her new name is Robita.
