Ruri

The granddaughter of Yuba. Her parents died when she was little, and since then she was raised alone by Yuba. She's equally close to everyone in the village with the exception of Sayo and Shin as they were the ones who spent more time with her in her childhood when they were learning spirit arts together from Yuba and that as fellow orphans they hung out a lot too.

She's Zen's elder brother's daughter, making her Rio's cousin
