Overlord: Ple Ple Pleiades - Nazarick Saidai no Kiki

Ainz unveils an upgraded version of Total Maniac, an item capable of forcing the residents of Nazarick to reveal emotions and impulses they normally keep buried. The experiment immediately goes wrong, and several Floor Guardians begin behaving in ways no one around them is prepared to handle.

Shalltear collapses into self-loathing, Cocytus loses his restraint, Demiurge's speech becomes bizarre, and even Aura and Mare act differently. With the Pleiades seemingly unaffected, Ainz recruits the battle maids to help contain the chaos. The greatest crisis in Nazarick is not an invading army, but a household of impossibly powerful beings who have suddenly stopped filtering themselves.
