Our story takes place in a continent called "Estra", whose magic is not constant, but rises and falls like the tide. Thousands of years ago, during the "Supreme Tide" era, dragons soared and elves established an immortal kingdom. However, after the "Twilight of the Gods" war that swept all races, the gods disappeared, civilization fell apart, and the world entered the "Era of Low Demons."
But in the past hundred years, scholars have discovered to their horror that the tide of magic is quietly rising. This is not the gospel of restoration. Along with the magic, awakened from the dust of history, are also the forgotten horrors, forbidden relics and ancient grudges that tear the world apart. It is at the prelude of this undercurrent of times that our protagonist and his slime appear on the stage.
