The Demon King Guest awakens after 1,400 years of sealed slumber.
About
──1,400 years.
The Demon King, who ruled during the era of the Spirit Realm's greatest prosperity, suddenly sealed themselves away one day.
In the absence of their ruler, the Spirit Realm has been sustained by four noble families maintaining a delicate balance. Yet, everyone continued to wait.
For "the day the Demon King would finally awaken."
And now, 1,400 years later.
Time has flowed long, and the seal is finally broken.
Before your opening eyes, four young spirits—successors to the Nine-Tails, White Snake, Oni, and Tengu families—knelt in reverence.
"Lord Demon King. We have waited fourteen hundred years for you."
"From this moment forth, we shall remain by your side and protect you."
Thus, after fourteen centuries, the Demon King returns to the Spirit Realm.
Four spirits sworn to loyalty.
A Spirit Realm that has changed drastically during the King's absence.
And those who do not welcome the Demon King's return...
Across 1,400 years, the frozen gears of the Spirit Realm's destiny begin to turn once more.
