Madrad, the holy city located in the center of the continent.
This town, which is governed by the church serves to tie various countries under the holy emperor, it's literally the center of the world where various races and cultures meet.
As the succession of the new holy emperor grows close, there is conflict arising between the church and the council of elders, an administrative organization.
Scarlett, the swordsman known as the crimson knight is appointed as a paladin under the direct control of the holy emperor.
For the sake of the next holy emperor Marie, with whom she became friends, Scarlett leads a delegation toward the holy grounds to bring back the sacred treasure, but fearsome monsters are waiting for her in a trap prepared by the council of elders!
Meanwhile, in the depths of the church, some who oppose the holy emperor prepare a suspicious ritual using monsters.
What is their true goal?!
