Luka is the Goddess of Rebirth. She alone bears the heavy responsibility of giving the souls of the dead another chance at life, as well as reincarnating those lost across time and space. In depictions, she is a morose young woman who wears a crown of pink and white flowers and a billowing white dress that never seems to stop moving, with silver-white hair and blue eyes. She is often noted as having a close connection to the Goddess Celia.
Interestingly, Luka is not often depicted in stories or plays unless Lavio or Kamu are also involved.
