Ranko: Miyama

This is the heart of the tension. Madoka is the true mystery—a girl with psychic powers and a hidden cigarette habit. Ranko initially despises Madoka because she senses that Madoka is similarly "wearing a mask" (the cool, perfect girl). Their relationship is a catfight of personalities. Interestingly, Madoka is one of the few people who sees through Ranko's act instantly, calling her "Rako" to unsettle her. Their grudging mutual respect by the end of the series is one of the most satisfying character developments.

The genius of Miyama Ranko lies in her duality. Unlike the archetypes she inspired, Ranko is not a "pure" Ojou-sama. Instead, she is a former Sukeban (female delinquent/biker gang leader) pretending to be a high-class lady.

The Backstory: Before the events of the series, Ranko was the infamous "Raki Raki" Rako, the leader of the "Hounds" biker gang. She was rough, aggressive, and spoke in coarse dialect. After a chance encounter where she was saved by Kyosuke (who didn't realize who she was), she became obsessed with becoming the "ideal woman" to appeal to him. She reinvented herself entirely. miyama ranko

This backstory explains every contradictory element of her behavior:

Miyama Ranko doesn't just act like an Ojou-sama; she performs it. And she performs it so perfectly that she often fools even herself. This metacommentary on status and identity was revolutionary for the mid-80s. This is the heart of the tension

Kyosuke is the object of her affection, but she is cursed to be the "second lead." She knows deep down that Kyosuke loves Madoka. Her arc is not about "winning the boy"—it is about accepting rejection. In one of the most mature moments in 80s anime, Ranko confesses to Kyosuke, he politely turns her down, and she accepts it. She doesn’t destroy his life or curse him. She simply cries, gets back on her motorcycle (yes, she still rides), and moves forward.

You cannot discuss Miyama Ranko without discussing the sound. Voice actress Chieko Honda brought a specific cadence to Ranko’s laughter—Ohohohoho!—that was equal parts haughty, ridiculous, and charming. Miyama Ranko doesn't just act like an Ojou-sama

Before Ranko, the Ojou-sama laugh existed, but it was generic. Honda’s delivery made it iconic.

Today, this laugh is the universal shorthand for the Ojou-sama trope. In Japanese media, from Lucky Star to Kaguya-sama: Love is War, any rich-girl laugh is intentionally or unintentionally a callback to Miyama Ranko. She is the Trope Codifier.

Her filmography is diverse, but she shines brightest in specific genres:

Where Hikaru is a child-like ball of sunshine, Miyama Ranko is a hurricane of fire and ice. Their rivalry is classic: the rich, cultured girl vs. the energetic everygirl. However, Ranko respects Hikaru more than she lets on. In several arcs, when a third party tries to genuinely hurt Hikaru, Ranko drops the act and uses her delinquent skills to protect her—proving that her rivalry is a game, not a war.
