Battle Game in 5 Seconds - S01

It was just an ordinary morning. Akira Shiroyanagi, a high schooler who loves games and Konpeito (Japanese sweets),is suddenly dragged onto a battlefield by a mysterious girl who calls herself Mion. The participants are told they have been "erased from the family register, involved in an experiment, and gained certain powers." Akira decides to win the game with his new powers and take down the organization. With a power no one expects and his "brain" skills, a new era of intelligence battles begins!
