Sunday VS Magazine: Trading Card Game is a crossover collectible card game published by Bushiroad in Japan, launched in 2008. The game pits characters from the two flagship Shogakukan and Kodansha weekly manga anthologies, Weekly Shonen Sunday and Weekly Shonen Magazine, against one another. Represented franchises include Ghost Sweeper Mikami, Urusei Yatsura, Ranma 1/2, InuYasha, Detective Conan, Negima! Magister Negi Magi, Love Hina, Rave Master, Kekkaishi, and dozens more, giving the game the character of a licensed crossover tournament. PSA population records confirm at least a first edition booster series. The game was an early product in Bushiroad's card game expansion phase before the company launched its larger Weiss Schwarz and Cardfight Vanguard lines. Little documentation of this game survives in English, which is exactly why it sits in the uncharted archive.
