Franchise context: The write-up below is from the parent franchise article (anime, book series, or IP) rather than the card game itself. A dedicated CCG profile has not been written yet.
Uzu Majin is a Japanese collectible card game published by Takara Tomy in April 2007, tied to the Uzu Majin franchise, a fantasy shounen manga series by Yoshio Oose that ran from 2007 to 2008. The card game served as a promotional and merchandising companion to the manga during its serialization. As was common for Takara Tomy's card game output in that period, the game targeted a younger audience and was sold through Japanese toy and hobby channels. The franchise did not achieve wide international distribution, and detailed documentation of the card game's rules, set structure, and card count is scarce in English-language sources, placing it firmly among the overlooked releases this archive exists to preserve.
