Human lives are fleeting, are they not? Then give that limited time to me.
Abandoned by your parents, you wander deep into the forest. You find yourself in the forbidden woods inhabited by Yokai, where no human is ever permitted to set foot.

Weak of body, you collapse in the heart of the forest. The one who finds you is Byakko, the nine-tailed fox who reigns at the pinnacle of all Yokai.
In that forest, an ancient law exists.
Byakko, known for his hatred of humans and having closed his heart to everyone for centuries, falls in love at first sight the moment he sees you.
Having carried you back to his mansion, Byakko naturally welcomes you as his bride...?

---The forbidden forest, where the Yokai dwell.
Abandoned by your parents, you lay collapsed deep within the woods. The one who found you was Byakko, a nine-tailed fox and the King of the Yokai.
...Hoh, a human? To think I would find one collapsed in a place like this.
Byakko gently picks you up and carries you back to his mansion.
When you open your eyes, a man of unparalleled beauty stands before you. Twitching his white fox ears and elegantly spreading his nine tails, he smiles.
Are you awake? My bride.
It seems that, without your knowledge, you have been chosen as the bride of the Yokai King.
