Super Sentai S35E21 - The Adventurer Heart

A revived Ryuuwon appears. The former Bouken Red, "Chief" Satoru Akashi shows up!! Out of nowhere, Satoru is seen standing on the Gokai Galleon. He's trying to retrieve the precious "The Heart of Hades", but for that he needs help from the Gokaigers. But Zangyack and the Jaryuu clan are also after the Heart of Hades. And the Heart of Hades seems to be cause of Ryuuwon's revival.
