Ramia emerges as a central antagonist within the magical girl saga, initially vying for rulership over the enchanted kingdom of Juraihelm. When the royal council crowns Tsunami—her rival—as queen instead, despite Ramia’s formidable magic and intellect, bitter resentment consumes her. Determined to delegitimize Tsunami’s reign, she orchestrates earthly chaos through proxies, exploiting her younger brother Rumiya to recruit Misao Amano. Transformed into the erratic Pixy Misa, Misao destabilizes Tsunami’s designated protector, Pretty Sammy, while Ramia engineers catastrophic threats: colluding with a tech magnate to hurl the moon toward Earth or manipulating the Lovely Madams cult to spread disorder. Repeated defeats by Pretty Sammy’s alliances intensify Ramia’s fury, manifesting in violent outbursts against Rumiya, whom she blames for failures.

Arrogant and cunning, Ramia masks her hostility behind false camaraderie with Tsunami, weaving intricate plots to seize power. Yet fleeting vulnerability surfaces when a comet’s impact erases her memories, temporarily rendering her timid and reflective, akin to Misao. During this amnesiac interlude, the alien Hiroshi shelters her, manipulating her buried grudges. Upon recovering her memories, she resumes her vengeful crusade, though Tsunami’s unexpected empathy during her fragility briefly thaws their antagonism.

Her tactics shift over time: partnering with Romio, a fellow disgraced noble, to siphon Juraihelm’s magic ends in betrayal, compelling her to ally with Pretty Sammy against him. Depleted after thwarting Romio, she channels residual magic to support Rumiya’s interventions on Earth. Final defeat leaves her spirit shattered, reduced to a listless figure until taunts reignite her defiance.

Though she exploits Rumiya’s loyalty, mocking his vulnerabilities, ambiguous traces of concern flicker—such as a diary entry hinting at protectiveness, later exposed as deceit. Academic rivalry with Tsunami and shared melancholic withdrawals when thwarted deepen her envious motivations.

Ramia’s legacy orbits relentless rebellion against perceived slights, cyclical destruction, and an inability to concede. As Tsunami’s foil, she embodies ambition clashing with empathy, her machinations propelling both turmoil and the protagonists’ evolution.
