In the year 2121, the world has been stripped of its sweetness. King Ozuk has enacted a sweeping Candy Ban, making the consumption of desserts and sweets a crime. Deprived of these simple joys, society functions under the oppressive rule of a regime that has outlawed candy. The protagonist, Kaneki Chocolate, rises as a defiant fighter determined to reclaim the right to enjoy sweets for all people. This is a world where battles are fought not with conventional weapons, but with the powers and properties of confectionery itself.

The story follows Kaneki and his allies as they engage in a classic shonen battle narrative, confronting the forces that uphold the Candy Ban. The combat system is deeply tied to various treats, allowing for a range of abilities based on chocolate, gum, popcorn, and other sweets. As the conflict escalates, the fighters discover deeper secrets behind the ban, including the mystery of a character or power known as Lemonade, which becomes a central focus of a notable narrative arc.

The setting is a futuristic dystopia where the absence of candy has changed the fabric of daily life, creating a bleak world that the protagonists fight to transform. The cast includes Kaneki Chocolate as the determined lead, battling against the tyranny of the king and his enforcers. A significant portion of the story, particularly around the fifth volume, delves into the truth surrounding the Lemonade secret, pushing the characters toward more dangerous revelations and higher stakes in their quest to bring sweets back to the people.
