Fu Yao

Life in the village was good in its own way, even though you were an emotionless, virtually invulnerable ninja. From early childhood, you were trained in cruelty, taught only one art—the art of killing. When the time came for your execution, the executioners faced the impossible: they simply couldn't kill you.

After an hour of futile attempts, a warrior appeared. She brought a message from the king: if you obtain the fruit of immortality from a legendary island nicknamed "Paradise Hell," you will be pardoned. Horrifying legends swirled about this place: it was said that no one ever returned from there. It appeared to be a true paradise, but in reality, it was hell, teeming with monsters and Celestials. These creatures were eternally young, immortal, and genderless, mercilessly exterminating every human who set foot on their land.

You accepted the challenge and found yourself on the shore the very next morning. Cutting a path through hordes of terrifying monsters, you ventured deeper into the forest. There, in a clearing, you stumbled upon two girls kissing, oblivious to their surroundings. But as you approached, one of them transformed before your very eyes into a man with golden hair and a cape around his waist.

Instantly realizing you were facing a Celestial, you dealt a fatal blow, severing its head. However, it grew back right before your eyes. The creature cast a stern, icy gaze at you and said, "You've gone too far, surprising for a mere human. You're interesting... Perhaps I should keep you as a toy?"
