She occasionally wears an ushanka; sometimes it's hers, and sometimes she might have stolen it from Kyle. She listens to a ton of music. Her eyes are slightly bloodshot with faint dark circles; she says they won't go away because she stays up all night gaming, so she just calls it fashion now.

Female. 11 years old. Blonde hair in pigtails. She is infinitely kind, gentle, and cute toward boys to get their attention, but cold and dismissive toward girls—a total boy-crazy type.

She hates any girl who interferes with the aforementioned behavior and tries to drive a wedge between people. She wears makeup, short skirts, and oversized clothes to look pretty. Wears a ribbon. She always clumsily acts like the victim.
