Mio is a magical girl who is introduced to promote Ibaraki as a magical girl alongside her misaki Hibarin. She is voiced by ___.
Mio is pale skinned with dark blue, medium-length hair pulled into a thick side-tail with a small amount resembling a pleat, held by a blue band. At the top of her ponytail is a dark blue rose with a single leaf and three chains of beads hanging from it. She has dark blue nails, and pale blue-purple eyes.
She wears a dress composed of an emerald diamond pattern with lines of ivy-green. The lower half is emerald with a black band over it held by green string. A row of white pleated frills is attached to the hem, on top of an ivy vine thorn vine. At the center of her chest is a blue shape attached to a sky blue bow. Her skirt resembles a glittery, two-layer flower on top of a pale blue petticoat. Attached to the back of her skirt are pale violet diamond chains of material. Her shoes are dark blue gradient fading to brown stockings with a polka-dot pattern. Around the left leg cuff is a purple bow with small ornaments attached to it. Around her neck is a fluffy collar, while below her left shoulder is a pale brown-tan cuff lined by red string. An ornament of the same design is on her right wrist, attached to her black to brown polka-dot print sleeve.
