Satori, an adept Chaos Magician, casts a spell to try and win back his lost love, Star. Lilith, mother of demons, has other ideas. Summoned by Satori's magic, she makes it her mission to manipulate and separate the doomed lovers.
Satori knows he and Star are meant to be together. He battles demons, travels worlds and even transcends death for her but, however much she begs, he can't grant her the freedom she craves.
