By herself (which is rare since she is rarely not with her best friend) Zosime is cheerful and upbeat, but sometimes a little outspoken. Zosime is never one to turn down a dare or miss a chance for an adventure. Zosime is the only daughter in a home full of boys, and it shows. She is rather tomboyish and her clothes are often full of patches. She doesn't care much for fancy stuff like the other girls in school though, and if they tease her for it she doesn't mind punching them in the face! Of course, this is why she spends more time in the princapal's office than she does sitting in class!
