Loco-Dol Daisakusen is a Japanese collectible card game published by Shichifukujin in May 2013, predating the anime adaptation of the source material by approximately a year. The game takes its name and theme from the "local idol" (locodol) concept popularized by the manga Futsuu no Joshikousei ga Locodol Yattemita by Kotaro Kosugi, which ran in Monthly Comic REX before spawning a television anime series by studio Feel that aired from July to September 2014. The Shichifukujin card game appears to have been an early merchandise product issued during the manga's serialization period, intended for fans of the original comic before the property gained broader visibility through the anime. English-language documentation of the card game's rules, card pool, or competitive activity is essentially nonexistent. The game is out of print and survives mainly as a footnote in the Locodol franchise's merchandise history.
