Arcadia Tribe of the Silver Ring TCG, released in Japan in October 2015, was a hybrid smartphone-linked trading card game developed and published by Kadokawa in collaboration with GREE Entertainment Products and Hobby Japan. The game launched on September 10, 2015, with a simultaneous release of three starter decks (Star Fire Society, Rougetsu Magic School, and Star Temple Knights Co. Ltd.) priced at 1,000 yen each, alongside a booster pack at 350 yen. The game's central innovation was tying physical card play to a companion mobile application, allowing players to operate both cards and smartphone together in the same session. The full title in Japanese marketing was Arcadia Tribe of Silver Key. Three distinct starter deck factions gave the game a school-rivalry aesthetic typical of mid-2010s Japanese card games targeting younger players. The game went out of print after a relatively short commercial run, and surviving documentation in English is limited.
