Suri is none other than Kanna Kashel's mother. She is a sorrowful, sweet woman who apparently lost her senses when her husband, Jeronn, disappeared. It has been Kanna's goal since then to find news of her father, whether it is an explanation, an excuse or his grave. Anyway she sees it, it will be a way to let her mother move on with her life.
Suri looks like an older version of Kanna with glasses and an affinity towards cats.
