Styled as a magical girl, Mii is portrayed in a dynamic pose that suggests she is about to unleash a spell. The figure features a schoolgirl-inspired magical outfit with a frilly, layered dress in pale pink and white accents, accented with a translucent cape, star motifs, and ribbon details at the waist and wrists. Her long hair flows behind her in soft, sculpted strands, with decorative accessories and a gentle gloss finish that catches the light. The figure includes a wand or staff prop with crystal-like embellishment, and a clear display base supports a lively, action-ready stance. Paintwork highlights fine lines in the costume, shimmering highlights on the hair, and subtle shading to convey depth. The overall presentation emphasizes whimsy and magical energy, making it a stand-out piece in a hobby collection focused on anime figures.

In the Popotan world, Mii is an ordinary girl who discovers an ancient artifact that awakens magical powers. Transformed into a Mahou Shoujo, she must protect a fragile dream diary that records moments from multiple timelines. Her powers focus on light and time manipulation, allowing her to slow her surroundings, create protective barriers, and heal minor wounds. She teams with her sisters to explore mysterious doors that appear in the fabric of reality, seeking to preserve memories while avoiding the attention of a shadowy organization that wants to erase them. While the outfit enhances her courage, Mii remains compassionate, quarreling with herself about the cost of power and the responsibility of shaping fate. Each mission adds color to her world and tests her resolve to keep the light burning for those she cares about.
