COVER Corporation announced a limited-time collaboration between hololive production and the Taiwanese mahjong game Celebrity Mahjong, starting July 15, 2026. The crossover features talents Houshou Marine, Hakui Koyori, and Juufuutei Raden, with in-game events, exclusive outfit sets, a cheering event, card albums, and a merchandise booth at Comic Exhibition in Taipei from July 23 to 26.
The crossover will be present at Comic Exhibition, Taiwan's largest ACG convention, from July 23 to 26 at TWTC Exhibition Hall 1. Visitors to the Celebrity Mahjong booth can participate in activities to win limited-edition merchandise including a body pillow, acrylic blocks, charms, and badges.
In-game, the three talents will sit at the mahjong table alongside players. An affection-point cheering event lets players earn and dedicate items to boost their favorite idol's ranking, with rewards including collaboration merchandise. A set of 12 digital card albums offers a grand prize of 12 million i-Coins for collectors who complete all albums. The collaboration runs for a limited time; cards become untradeable after the event ends.
