Pandemonium

About

Pandemonium is a major antagonist, with the Pure Concept of Chaos.

The daughter of Countess Libelle and older sister of Manon Libelle, Pandemonium is a Lost One that became one of the Four Major Human Errors with her Pure Concept of Chaos.

Described by her mother as a bright girl "full of energy" who adores singing and dancing, Pandemonium is cheery and playful, though with her Pure Concept and becoming a Human Error, she has no memories or identity associated with her previous self. Rather, her sole purpose has transformed into inflicting as much chaos as possible.
Her mother also commented that Pandemonium loves movies above all - after becoming a Human Error, Pandemonium states that she loves horror movies and strives to replicate them, likely due to her Pure Concept.


After being sealed in the fog for over a thousand years, Akari minutely warped the fog by using her ability to manipulate time to escape from the Pandemonium's monster contained in the fog. Although still trapped, Pandemonium was able to manifest part of herself in the town of Libelle with the assistance and bodily sacrifice of Manon.
