Built around the characters from LOTTE's Bikkuriman chocolate wafer snacks, this comedy fantasy is set in a world where Bikkuri-Man stickers are so precious they travel by armored cash truck. A year earlier, a notorious theft known as the 300 million sticker case made headlines. Yamato, a high schooler working part-time making deliveries, gets pulled into a sticker war between two rival convenience stores facing each other across the street. Angel Mart, run by its Phoenix store manager, is known for its handy glitter stickers, while the Devil Store fights to win over Bikkuri-Man fans of its own. Old comrades end up on opposing sides as a fateful clash gets underway.
