If a telepath, a clairvoyant, a vice detective, a ninja with super reflexes, a spirit medium, an oil magnate, an extremely lucky boy, and an extremely strong man were to fight it out in a rock-paper-scissors tournament, who would you bet your money on? Just because it's a simple game with simple rules doesn't mean the matches will be simple. Mind games, cheat abilities, interesting characters, great humor, this manga has it all!
