A character from Genshin Impact.
Tonia is the younger sister of Tartaglia (Genshin Impact) and the third-youngest child in her family, only being older than Teucer (Genshin Impact) and Anthon (Genshin Impact). She and her older brother are extremely close, with Tartaglia addressing her as "Dearest Sister" and referring to himself as her "loyal knight".
As she has yet to make an official appearance, her design is up to artist interpretation.
