Neo Angelique Abyss

Angelique, a young student, lives a peaceful life at her school, but the threat of Thanatos attacks looms large in the rest of Arcadia. Nyx and Rayne, Purifiers with the ability to eliminate Thanatos, arrive at the school, seeking Angelique's help as the only potential female Purifier. When a Thanatos appears, the school is attacked, and despite Nyx and Rayne's efforts, they're defeated. This traumatic event prompts Angelique to take action, leading her to become the first female Purifier in Arcadia, also known as the "Queen's Egg".
