Synopsis

The chapter reveals that the mirrored canyon is actually a gate to the demon realm, triggered by a character's death. The heroes realize that the gate is not fully open, but if it does, the area will become hell. They learn that the only way to close the gate is by using a powerful one-time-use sword called "Brave," which is the posthumous work of the Cardinal's father. The sword stores an enormous amount of power but will break after one swing.
