Rane is a fairy princess who crosses into the human world from an alternate dimension. Her mission is to locate the Four Treasures of Heart. This quest brings her into contact with Gou Takarada, an amateur treasure hunter seeking the legendary Salamander, forging an unconventional partnership centered on their mutual hunt for mystical artifacts.

Physically, Rane stands only about six inches tall. She possesses functional wings for flight, pointed ears, and an overall ethereal appearance.

Her communication presents a significant barrier; she speaks primarily in Japanese-sounding gibberish unintelligible to humans. Official subtitles translate her speech into nonsensical phrases like "Cigar store!" during moments of panic, fueling comedic misunderstandings.

Her relationship with fellow fairy Leen Kyami Kuunyo adds complexity. Leen displays protective and possessive behavior towards Rane, including an unexpected kiss. Rane reacts to this advance with apparent neutrality or passive acceptance.

Rane exhibits typical fairy abilities like flight and possible connections to natural magic, though her specific powers are undefined. Her presence frequently triggers chaotic events, often unintentionally escalating conflicts during treasure hunts. Notably, her actions contribute to disrupting a secret project aimed at transforming Gou's hometown into an amusement park.

Due to the OVA's short runtime, Rane's character development remains minimal. Her core quest for the Four Treasures concludes unresolved, leaving her story incomplete.
