During his school computer class, Saneatsu Narita is presented with a strange screen posing a yes-or-no question that quickly disappears. The next day, Saneatsu wakes up to a world where everyone, save for himself and a few others, is dead. An announcement from a mysterious figure known only as the Emperor begins to shed light on the situation. The question that Saneatsu saw on the screen is part of a game called Tasuuketsu. Every day, the survivors will see a question appear on a screen, and answering it will determine who lives to see the next day. Responding the same as the majority will guarantee death, and the last player standing will earn the right to meet the Emperor. Saneatsu resolves to beat the Emperor at their own game, making use of the hidden envelopes containing powers that can aid the players. With the help of his small group of friends, Saneatsu must avoid falling into the machinations of the other players and win this wicked game.

The series is a historical drama aesthetically and boldly adapting the life of Oda Nobunaga in his teens up to his time as a warlord against his brother, Nobuyuki.

The Kingdom of Clays faces a dire crisis: an assassination attempt has just been made on its own Princess Lynneburg, and its neighboring countries eye the aftermath like starving vultures, plotting the Kingdom's downfall. The ensuing conflict will shape the face of the continent for centuries to come...but Noor doesn't have a clue about any of that! Having freshly arrived at the royal capital after over a decade of rigorous, isolated training at his mountain home, he's dead set on achieving his childhood dream of becoming an adventurer, even if the only skills he possesses are useless ones. Sure, he can "Parry" thousands of swords in the span of a single breath, but everybody knows you need more than that if you want to be an adventurer! Our hero's road to making his dream come true will be long(?) and arduous(?)—but if there's one thing Noor's not afraid of, it's some good ol' fashioned hard work!
