In a place like no other, on a mystical island in the shape of tear drop, two sisters are born into a family of oracles. Beautiful Kamikuu is admired far and wide; Namima, small but headstrong, learns to live in her older sister's shadow. On her sixth birthday, Kamikuu is chosen as the next Oracle, while Namima is forced to become the goddess of darkness, destined to spend eternity guiding the spirits of the deceased to the underworld. As the sisters serve opposite fates, so begins a journey that will take Namima from her first experience of love to scalding betrayal.
