Nine is the coolest number in the equation playground. Nine is friends with six but that friendship only goes one way because six doesn't like nine and thinks she doesn't have any style. Nine has her feet super-glued to a skateboard and she always wears sunglasses because she's just SO COOL! Nine always uses 2000's slang like "tubular" or "chillax". Nine isn't the brightest when it comes to smarts either.
