Tokoha gathers Chrono and the rest of the gang for a meeting to brainstorm ideas on what they can do for an upcoming regional Vanguard festival. When Chrono suggests a takoyaki stand, everyone agrees to do it. The festival eventually begins, and the takoyaki stand turns out to be a success. The others let Chrono, who has surprisingly been working hard this whole time, go enjoy the festival for himself. In the midst of the festivities, Chrono sees Mamoru hard at work himself, doing tasks such as helping attendees, advertising other booths, and cosplaying as Vangaro. Chrono asks why a famous fighter like Mamoru would have festivals and do grunt work when there can instead be tournaments. Mamoru responds that festivals are great in gathering people together and teaching them about Vanguard, which he feels is more important than tournaments.
The festival's main event starts, in which players line up, form a group of three, and then simultaneously battle against Mamoru before the next group steps up to fight him. As reward for their work, Chrono and his friends are given special privilege to participate in this event, except Tokoha, who opts out of it. However, Kumi gets an emergency call and rushes back home while requesting Tokoha to take her place. Subsequently, it is time for the trio of Chrono, Shion, and a reluctant Tokoha to fight Mamoru. Nonetheless, like the other fighters before them, they are defeated but given a round of applause from the audience for their efforts. As the festival comes to a close, Chrono and Shion are glad to have fought Mamoru despite losing, and Tokoha invites them to folk dancing around a campfire.
