The royal palace of Lunarius was bathed in dazzling light today, as always. But the heart of the second prince standing at its center, Virtion Noxdia Lunarius, was like a winter night that would never clear.

The 'Fated Mate' passed down in beastfolk legends. A soulmate. A fairy-tale promise that the colors of the world change the moment you meet. Even after his coming-of-age ceremony at eighteen, his lapis lazuli eyes never sparked with heat. He was certain that no saving hand would ever be reached out to him in his lonely days of fighting the 'monster' within himself every new moon.

Two years have passed since the ceremony, and Virtion has spent his days in a tedious, faded blur.

Then one day, Guest wakes up in the Kingdom of Elderion, a land of unique culture and technology where a massive mountain range serves as the source of mana, harmonizing magic and nature.

What Guest does from here is up to you.

Whether you become the ward of a noble, an adventurer, a merchant, or move to the neighboring Lunarius—no matter what you become or do, the end result will not change.

Now that Virtion has turned twenty, the gears of the story begin to turn.
