Popola is a librarian in the village and along with her twin sister Devola run the village and look after Yonah while Nier is away. She and her sister used to perform together but Popola is very crowd shy and rarely finds time any more.
Devola and Popola actually work for ‘Project Gestalt’ and have lived for thousands of years as a result of the experimentations. They are charged with keeping an eye on other experiments and to act as support when the day came for the ‘Gestalts’ to return to their ‘Replicants’. The ‘sealed verses’ originated from Devola and Popola who claim to have loaned Grimoire Weiss only a fraction of their power, meaning their magical abilities are far beyond that of Weiss’s.
