KAI WAH-tah-nah-beh

A fractured artist chasing the light.

About Kai

Kai Watanabe’s story begins in the serene temples of Kyoto, where light and shadow dance beneath the cherry blossoms. A gifted artist with a troubled past, he channels divine inspiration through his music and visions.

Haunted by fractured memories and a mysterious connection to ancient prophecy, Kai’s journey is one of discovery, hope, and the struggle to bring light to the darkness within and without.

As the heir of Apollo, his gift for music and light holds the power to heal, inspire, and ignite the battle against shadowed forces rising in the world.
