The story takes place in a fictional world, where the demon is about to wake up from his slumber, and the world will become a sea of blood and fire. In order to defeat the demon and make it sleep again, six heroes are selected by God, and they will have flower emblems on their bodies as a mark. People call them "Six Flower Heroes". However, this time, there are seven heroes selected, which means that among the unrestrained and cheerful Nashetanya (voiced by Yoko Hikasa), the cold and taciturn Fremi (voiced by Aoi Yuuki), the strong Mora (voiced by Rina Sato), the highly intelligent Hans (voiced by Kenichi Suzumura), the arrogant and poisonous Chamo (voiced by Ai Kakuma), the mature and steady Goldof (voiced by Koki Uchiyama) and the timid Loronia (voiced by Hisako Kanemoto), there is a traitor among these people.
