To summarize this manga really had everything, action, suspense, strategy, comedy, and a very satisfying ending, and its short, only a few chapters but its like just the tournament arc of a really good battle manga but even shorter. A lot of great ideas about what you can do with a simple game of rock, paper, scissors and some super powers. A ninja(super reflexes) vs clairvoyant(can see the future) vs mind reader vs billionaire vs an extremely lucky guy vs hypnotist vs genius detective vs supernatural shrine maiden. They all try their best to come up with so many strategies utilising their specific skill set with the winner of the tournament will be granted one wish without conditions. Everyone has their own reasons for entering
SPOILER ALERT, the lucky boy loses.
