Many years ago, the last remnants of humanity were forced to retreat behind the towering walls of a fortified city to escape the massive, man-eating Titans that roamed the land outside their fortress. Only the heroic members of the Scouting Legion dared to stray beyond the safety of the walls – but even those brave warriors seldom returned alive. Those within the city clung to the illusion of a peaceful existence until the day that dream was shattered, and their slim chance at survival was reduced to one horrifying choice: kill – or be devoured!
It is the Taisho Period in Japan. Tanjiro, a kindhearted boy who sells charcoal for a living, finds his family slaughtered by a demon. To make matters worse, his younger sister Nezuko, the sole survivor, has been transformed into a demon herself. Though devastated by this grim reality, Tanjiro resolves to become a "demon slayer" so that he can turn his sister back into a human, and kill the demon that massacred his family.
With Majin Buu defeated half-a-year prior, peace returns to Earth, where Son Goku (now a radish farmer) and his friends now live peaceful lives. However, a new threat appears in the form of Beerus, the God of Destruction. Considered the most terrifying being in the entire universe, Beerus is eager to fight the legendary warrior seen in a prophecy foretold decades ago known as the Super Saiyan God. The series retells the events from the two Dragon Ball Z films, Battle of Gods and Resurrection 'F' before proceeding to an original story about the exploration of alternate universes.
