Neo Angelique Abyss

A young girl named Angelique lives a quiet life at school while violent attacks by creatures called Thanatos grow more frequent. Two individuals known as Purifiers, capable of fighting the Thanatos, arrive and offer Angelique a role in their mission, as she possesses the potential to become a Purifier herself. Before she can decide, a Thanatos invades her school. The Purifiers, Nyx and Rayne, struggle against it but are overwhelmed. As her classmates are endangered and the Purifiers defeated, Angelique's determination to protect them emerges. She activates her ability and becomes the first female Purifier in Arcadia, referred to as the "Queen's Egg."
