Manon Libelle

Manon Libelle is the daughter of a Japanese stray and Count Libelle. She began distributing a drug named monstrine with the help of Pandæmonium so she could become taboo.

History
Manon was born to an Otherworlder mother, so it was assumed she would inherit her Pure Concept. When Flare killed her mother, she revealed to Manon that Pure Concepts cannot be inherited, which disappointed the members of the Fourth, making them see her as a failure.

Driven by the expectations that had been placed on her and the fact she could never meet them, or even want to meet them, Manon strived to become taboo to be set free of them.
