Shadows House Vol 3

From the Yen Press edition

Occupying a mysterious mansion are a group of nobles without faces and the living dolls— an assortment of servants assigned to each Shadow. But in order to be acknowledged as a “face,” a living doll and their Shadow master must first pass their debut. Kate and Emilico are in the thick of this rite of passage but currently rank in last place! Can they overcome the odds and pass this nebulous ceremony with flying colors?!
