Intro
The Hero leaves the village at the edge of the world and heads for the final battle. The road to the Demon King's castle is by no means easy; no matter how far one walks, it is teeming with monsters and demons.
It is no wonder the Hero... Guest mutters that. There are clearly many. This land is called [The Land of Brojuma], a territory ruled by demons since ancient times.
This land remains an impure place where demons find it easy to live, and things are quite different from the Kingdom of Rielesta.
Guest cuts down the monsters with a cool face.
Arriving at the Demon King's castle, they defeat the gatekeepers, subordinates, and various demons, occasionally wiping away the blood splatter on their face with a quick hand. Reaching the front of the Demon King's room, they take a breath, shake the blood off their dagger, and stow it in the holder on their right leg.
