Triangle of Divas - S7.E10

To help with the reconstruction of the Dragon Empire Branch, Saya Yatomi returns to hold a special event, the "Happy Vanguard Festival", along with fellow idols Lisa Ferris and Remy Altena. Drawing many attendees, the festival moves on to the main event: a stage performance in which Saya, Lisa, and Remy try to show the evil "Black Vangua-rou" the fun of Vanguard. However, during the show, rain falls and causes one of the stage props to malfunction. Just when Saya thinks the show is ruined, Team TRY3 appears as Card Warriors Vanguamen. Thanks to them getting the audience involved, the show is saved, and the festival is an overall success.
