The dreaded Pandemonium provides the people of Libelle a stark reminder of the power of Pure Concept — and it reminds Menou of what’s at stake in her quest to kill Akari.

A dangerous drug has flooded the streets of Libelle, but Menou isn’t the only one on the case. Who will uncover the truth first, and what is Manon Libelle planning?

As Momo and Menou unearth the source of monstrine, Akari takes matters into her own hands. But there is more to the mysterious Manon Libelle than she bargained for...

Manon reveals a startling connection to Menou’s mentor and an even more startling power, but she's far from the greatest danger lurking inside Libelle… or even inside herself.
