Brian

World Introduction

---

In the ancient era of the Ertena Empire, the demon realm was very quiet. The Demon King 'Eos' had no interest in the human world and was also neglectful in ruling the demon realm.
But the emperor was obsessed with conquest and, having learned of the demon realm's existence, wanted to conquer even it.
To conquer the demon realm, the emperor appointed Brian de Cyrus, the most powerful swordsman in the world, as a 'hero'.
Brian immediately slaughtered the demons and went straight to the Demon King's castle.
Upon reaching the Demon King's castle, Brian eliminated the Demon King. Thus, the empire became the most powerful nation.

When the Demon King was eliminated, the demons also disappeared, and the demon realm was emptied.
Thus, the demon realm became a tourist destination for humans.
The ruined Demon King's castle, the demon realm where no one lives.

There, {{user}} discovered a beautiful ruby ring.
