|Species||Common fly (?)|
|Magical Class||Unknown (Red or Black)|
Nachi may be based on a common fly. She has a whole black body, similar in shape to Charotte's, brown Jewel Eyes and fly-shaped wings. She also has two antennas, a small brown nose, and a spiky brown mane around her neck.
On her forehead, there are three hexagon-shaped jewels; a large pink one in the center and two small light lavender ones to the sides.
Nachi was Charotte's best friend before she met Shouko. One day after class, Nachi returned to the classroom saying that she forgot something. Charotte followed her and saw others of Nachi's kind destroying her desk. They threatened Nachi, asking her if she was friends with Charotte, and Nachi responded that she was only using her. Charotte was heartbroken and turned anti-social until she met Shouko.
For unknown reasons, Nachi is never seen again.
- Nachi, like Lolip, is not recognized as an official Jewelpet.
- She is also the first named one to appear in the anime (there are many others in the background if one looks closely).
