Tousuke Rokudou is a first-year attending Aomori High, a school full of delinquents. He is often bullied by his classmates due to his incompatibility with their behavior, the only exceptions being his two good friends who are also social outcasts. Frustrated at the way they are treated, the three wish they could stand up and claim the fun, peaceful school life of their dreams. However, Tousuke's life takes a drastic turn when he receives a package from his late grandfather containing their family heirloom, a scroll said to possess the power to save him from impending danger. Upon holding the scroll, a sudden glow emanates, leaving a strange mark on Tousuke's forehead. Thinking that he's received the means to free himself and his friends from their daily treatment, Tousuke is shocked to find out that its effects are far different than what he had imagined. Although his bullying continues, he realizes that the mark from the scroll acts as a charm, capturing the hearts of delinquent girls—in particular, Ranna Himawari, the strongest of them all.

An ancient legend states that with the revival of the Demon God, six heroes—the Braves of the Six Flowers—will be chosen by the Goddess of Fate, granting them power to rise up against the fiends attempting to turn the world into a living hell. Adlet Mayer, self-proclaimed Strongest Man in the World, has arrived at the continent of Piena in hopes of becoming a Brave. Although it doesn't go as smoothly as he had planned, Adlet is ultimately chosen as one of the six heroes shortly after being greeted by Nashetania Loei Piena Augustra, crown princess and fellow Brave. Rokka no Yuusha follows the two as they embark upon their destined journey to fight the Demon God, intending to meet up with their fellow heroes at a small temple outside of the Land of the Howling Demons, the fiends' domain. However, when they finally unite, seven heroes are present, and soon the others begin to suspect Adlet to be a fraud. Now on the run, Adlet must utilize his unique skill set and wit in a fight for his life to identify which member of the group is the true impostor before it's too late!
