Mahjong Soul is collaborating with The Idolm@ster Shiny Colors in a limited-time event, "Shiny Concerto," running until December 15th. This exciting crossover features adorable characters and engaging gameplay.

The event introduces a new game mode, "Limitless Asura," offering increased event token rewards and a fresh storyline. Four Idolm@ster Shiny Colors characters – Toru Asakura (cool and carefree), Madoka Higuchi (cynical and stylish), Koito Fukumaru (soft-spoken and studious), and Hinana Ichikawa (energetic and loyal) – join the Mahjong Soul roster, challenging existing characters.
