The story takes place in a fictional world called Arcadia, where life-draining monsters called Thanatos plague the populace.

Nyx is interested in the potential power she possesses and invites her to join his organization, but she refuses since she wants to become a doctor, like her father. However, when her school is later attacked by a Thanatos, she ends up activating her powers in her want to protect those in danger. After purifying the creature, she finds out she has a unique purifying power, and that is she the one that has been foretold in legends, the "Queen's Egg". It is then that her journey begins, and she becomes the only female Purifier in the world. This series is noted as being quite similar to Kiniro no Corda, otherwise known as La Corda D'oro.
