Misty serves as one of four sworn sisters under Aira, leader of Machine Island's Hachiryoukaku faction. She operates a Psycho Gear, a specialized combat mecha exclusive to the all-female Hachiryoukaku forces. These mecha wield beam weaponry and deploy defensive barriers for base protection. Misty's Psycho Gear boasts a distinct design, signifying her position within Aira's elite guard.

Alongside her sisters Hurricane, Fancy, and Flash, Misty comprises an Amazon Brigade dedicated to safeguarding Hachiryoukaku interests. Their names derive from transformation modes of Cutie Honey, reflecting their thematic inspiration. During clashes with Kiba's Army, Misty becomes the target of an assault attempt by Kiba's lieutenant, who breaches her Psycho Gear's cockpit mid-battle. The intervention of Mazinkaizer SKL thwarts this attack, crushing the assailant.

Misty and her sisters maintain a cooperative alliance with the Skull Force operatives, setting them apart from the hostile factions led by Kiba and Garan. Their primary role involves combat in support of Aira's forces during the conflict for control of Machine Island.
