On February 9, 2023, the annual “music festival” by Kamen Rider x Super Sentai was held at Yokohama Arena in Japan. The theme of this year's show is "Extraordinary", with the acclaimed casts of "Kamen Rider Geats" and "Avataro Sentai Donbrothers" as the main characters. Marvel at the surprise and excitement on stage when the popular casts and successive theme song musical artists gather together! Japan's largest hero event consists of a talk show by the cast of "Geats" and "Donbrothers", and a gorgeous music live performance by the artists who give life to the Kamen Rider & Super Sentai series.

Yuichi Katagiri, a high school student, is abducted with four of his friends and forced to participate in a "Friends Game" to pay off a debt he was suddenly saddled with. The game is supposed to be easy to beat as long as you have friendship, but for some reason Yuichi and his friends are unable to beat the game. They suspect the existence of a traitor, and their friendship gradually begins to crumble. The ultimate mind game show is about to begin!

Ryuji (Taisho Iwasaki), Satoru (Ryuga Sato) and Atsushi (Hidaka Ukisho) are friends in high school. They are classmates in the 2nd grade class B. They appear like troubled students, but they are not. They are actually country boys. When they are at their secret place, they suddenly feel a big shake and hear the sound of thunder. Then next moment, they see a man Sanpei wearing a dirty military uniform with a backpack and holding a bayonet. Sanpei came from the past, right before the end of the war in Guam. Ryuji, Satoru and Atsushi enjoy their time with Sanpei. They think that being with Sanpei, their lives might change and they ask him to spend summer with them. Class President Michifumi (Yuto Nasu) and twin brothers Akihiko (Naoki Fujii) and Kazuhiko (Issei Kanasashi) join the group.
