Angelique's peaceful school was unaffected by the frequent attacks of the monstrous Thanatos, but she remained oblivious to their atrocities. One fateful day, two Purifiers arrived - men with the ability to vanquish Thanatos. Nyx, one of the Purifiers, identified Angelique's potential as the sole female Purifier and urged her to join their crusade. However, when the menacing Thanatos invaded their school, Nyx and Rayne, the other Purifier, fought an intense battle but were eventually overcome. Watching her classmates fall, Angelique was stirred with the burning desire to save them. She decided to become Arcadia's only female Purifier, earning herself the title of the "Queen's Egg."
