While her twin sister is a bard who is a regular performer at the tavern in Nier's village, Popola is the librarian in charge of the village library. Both sisters are considered the leaders of the village and are always looking out for Nier's daughter Yonah during his frequent absences. Popola is the one who gives him missions for the main storyline.
It is revealed when the player is in the Shadowlord's Castle that both Devola and Popola are android scientists/observers for Project Gestalt. The twins are revealed to have lived for thousands of years as a result of the initial experiments of the project, and have thus been charged with keeping eye on other experiments as a result: namely over the members of the entire party, including Yonah. They were made to provide support when the day has come for Gestalts to return to the Replicant's vessels. They are tasked with extracting data from Gestalts’ souls, making new Replicants' bodies, and returning a dead Replicant's data to its Gestalt.
- "Those two have watched the world wither for time immemorial. The cruelness of such a fate is difficult to imagine."
- —Weiss, after the twins are revealed as androids.
Before dying, the twins revealed that the Sealed Verses originated from the experimentation on them both, stating that they only loaned Grimoire Weiss a fraction of their power. Thus, meaning that their magic and capabilities are far superior to that of Grimoire Weiss.
- "Stop? Stop? You want me to stop? You think I have the luxury to stop? You cut down my sister like an animal and you tell me to STOP!? No one STOPS!! It's way too late to STOP! No one... STOOOOOPS!!"
- —Popola, after Devola's death
Popola is killed by her own attack along with Emil when the latter sacrifices himself to save his friends and counter the magic.
- Like Devola, Popola's name is a reference to the weapon "Devolapopola" in Drakengard. According to the databook of said game, Taro Yoko personally liked the weapon story and wished to someday make them characters in one of his projects. They are named after two dogs owned by one of his acquaintances.
- According to Nier, Popola doesn't drink alcohol because it sends her into a violent rage. He describes her by saying, "Popola doesn't look it, but after a few, she's the strongest in the land.". Nier explains that she even once knocked down a tavern wall (although, this could possibly be exaggeration).
