Fuwari Midorikaze hails from Europe, likely Switzerland, specifically residing in the Palps region. She possesses fair skin, bright yellow hair cut just above the shoulders, and a distinctive braid crossing her head like a headband, all consistent across depictions, paired with fuchsia-colored eyes.

Her name reflects core traits: "Midorikaze" combines "Midori" (green) and "kaze" (wind/style), while "Fuwari" signifies lightness, gentleness, and softness. She embodies a "yurufuwa" personality—relaxed, easygoing, and gentle—often approaching situations in her own unique way, which can sometimes complicate matters for others. Inherently friendly, she strives to befriend everyone. An animal lover, she demonstrates care for creatures and possesses some ability to communicate with them.

During the idol world crisis in "PriPara Mi~nna no Akogare Let's Go PriPari," Fuwari returns to her homeland. There, she reunites with her grandfather. Alongside fellow idol Ajimi Kiki, she performs the duet "Come and Join This Song-Hee-Hoo" for him, aiming to bring comfort and joy amidst the spreading darkness threatening PriPara. This act precedes both idols continuing their journey to help resolve the larger conflict.

Fuwari's preferred brand affiliation is CoCo Flower, aligning with her nature-themed character. She maintains significant idol relationships, including membership in the unit Tricolore with Hibiki Shikyoin and Falulu, and participation in the dream team Dressing Flower alongside Laala Manaka. Early design iterations featured long, thick yellow hair and a blue-and-white attire theme, later finalized to more closely reflect her floral and gentle attributes.

A notable film scene involving scissors and a wolf directly parallels the woodcutter's action in the "Little Red Riding Hood" fairy tale.
