Ericht "Eri" Samaya
About
A four-year-old girl who lives with her family at Fólkvangr. She is the daughter of Elnora and Nadim. Ericht is an innocent child, and so curious that her parents sometimes don't know what to do with her.
Although Suletta was long speculated to be an adult Ericth, it was revealed in Season 2 that not only did both girls have a noticeable age difference, but that the real Ericht was unable to survive the aftermath of the Prologue and her mind was used to create Aerial, Suletta's mecha. Thus, one of the main true goals of Eleonra, the mother of both sisters, is not only revenge for her husband and colleagues, but also the return of Ericht to a real human body.
