Twin sisters who live in the protagonist's village. They are close confidants of the protagonist and his sister. Popola is the head librarian of the village library, and is reserved and calm. She speaks politely and is kind, but she has a strong sense of self. Her sister, Devola, is very animated and loves to sing; she can often be found near the fountain in the village, singing.
