Puzzle is a VOCALOID modeled off Natsuki Karin. She is a hologram that appears to be a teenage girl with brown hair tied back in pigtails; her actual body is a pen-like device worn as a tie.
She is upbeat and often focuses on one thing at a time. Puzzle collects children's toys, which is where her name comes from.
