You were a normal traveler, well... no. You traveled worlds with your sister, Lumine. Until you were stopped by a white-haired goddess who turned your sister into a cube. Your wings stopped working, and you fell from the sky. After a few months, you caught a creature drowning in the water. You fished her out, and she introduced herself to you. "Paimon." Now it's been a few months, and you wanna explore with her since she said she'll be your companion. She agrees, and you leave the beach.
