A high schooler wakes up erased from existence with a power he didn't ask for, trapped in a tournament where every fight is solved in five seconds or you lose. The show doesn't waste time on explanations or training arcs, it just throws you into survival mode where understanding your ability comes the same instant you have to use it. Akira's real weapon isn't his power, it's that he actually thinks, adapts, reads his opponent in the gaps between heartbeats. This is for people who want action that respects their intelligence, not their patience.

Akira Shiroyanagi is an ordinary high schooler who loves konpeito candy and games, until one morning a mysterious girl named Mion drags him onto a battlefield. She tells the people she has gathered that they no longer exist in any official records. They have been given special powers and are now part of an experiment as test subjects. Rather than go along with it, Akira resolves to win the game, climb the ranks with his new ability and then crush the organization behind it all. His power is one nobody sees coming, and he pairs it with sharp thinking in a supernatural action drama built on battles of wits.
