Neo Angelique

The story takes place in a fictional world called Arcadia, where life-draining monsters called Thanatos plague the populace. The only ones who have the power to exterminate these creatures are Purifiers, but only a few exist. One day, Angelique, who is just a presumably normal girl attending school, is visited by Nyx, a rich gentlemen, as well as a Purifier, who created an organization comprised of Purifiers dedicated to eliminating Thanatos. 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.

The protagonist is a normal high school girl attending Melrose Girls' Academy in Arcadia. One day, she is visited by a gentleman named Nyx and learns that she has the dormant power to purify Thanatos, or incorporeal monsters that prey on the everyman. She leaves her school life to join Nyx's Thanatos exterminating business: "Aube Hunters". She soon realizes that she is the only female with purification powers because she is the oft fabled Queen Egg, or a legendary savior. Her goal is to work with her fellow Aube Hunters to eradicate Thanatos and restore the land's peace.
