TASUKETSU -Fate of the Majority- - S01

During computer class, Saneatsu Narita sees a strange screen with a yes-or-no question that vanishes almost immediately. The next day, he wakes up to a world where everyone except him and a few others is dead. An announcement from a mysterious figure known only as the Emperor starts to explain what happened. The question Saneatsu saw on the screen is part of a game called Tasuuketsu. Each day, the survivors will see a question on a screen, and their answer will decide who lives to see tomorrow. Giving the same answer as the majority guarantees death, and the last player left will earn the right to meet the Emperor. Saneatsu decides he will beat the Emperor at their own game, using hidden envelopes that contain powers to help the players. With his small group of friends, he has to avoid the schemes of the other players and win this cruel game.
