Ganyu is a youthful-looking woman with the physical appearance of a late-teenage girl to her early twenties in terms of her appearance (in spite of her actually being thousands of years old). She has long blue hair that fades into a brighter shade at the tips as opposed to the lighter shade it is the closer it gets to her scalp. Her eyes are a mix of pink and purple. Ganyu is normally quite optimistic and very hardworking. She even outright admits that working is her hobby.
