In this universe, Bikkuri-Man sticker values are so high that they require specialized transportation vehicles for transport. Last year, there was a significant robbery case involving 300 million Bikkuri-Man stickers, known as the "300 million Bikkuri-Man sticker case." Today, Yamato, a high school delivery part-timer, becomes embroiled in a conflict over stickers between two competing convenience stores. Angel Mart, owned by the Phoenix store manager, offers easy-to-use glitter stickers, while Devil Store tries to lure Bikkuri-Man fans with its own store. Former friends are now divided into allies and enemies, marking the beginning of their destiny battle.
