OVA
Description
Reika Ayanokouji presides over the Etiquette Club at St. Ignacio School for Girls. As the heiress to Uruyasu Heavy Industries, this role directly shapes her duties and drives her actions. Her family created the powerful Battle Skipper technology, and she fiercely protects these mecha systems, determined to prevent their acquisition and misuse by malevolent forces.

She embodies a consistently calm, soft-spoken, and collected personality. This composure stands in sharp contrast to the often impulsive and reckless nature of her vice president, Rie Shibusawa. Reika strategically cultivates her image as a refined heiress, using it to mask the Etiquette Club's true function as a front for the Exters, a covert task force utilizing Battle Skippers to combat threats.

A defining blood relation fuels her central conflict: she is kin to Sayaka Kitaouji, president of the rival Debutante Club and heiress to Makuhari Industries. Sayaka's ambition for global domination through Battle Skipper misuse ignites their bitter rivalry. Reika's core mission is stopping this outcome. When Sayaka demands she disband the Etiquette Club and surrender the Uruyasu Battle Skippers, Reika refuses, upholding her principles above familial pressure or ties.

Her leadership within the Exters is decisive. She leverages her authority to accept novice Shihoko Sakaki into the club despite initial doubts, recognizing potential. She commands during critical missions, including direct confrontations against Makuhari forces. Even captured by Sayaka, her resolve holds; she rejects offers of subordination and maintains faith in her team's ability to secure her rescue. After battles, she consistently acknowledges her comrades' efforts and reinforces their shared purpose.

In combat, Reika pilots the BSX-1 Testa Road, a high-speed red Battle Skipper from Uruyasu Heavy Industries, armed with a beam saber and rocket launcher. She executes its special attack, the Fractal Crossing Attack, during coordinated strikes against enemies. This mecha represents her family's technological legacy and serves as her primary weapon opposing Makuhari's ambitions. The Exters operate from the mobile fortress Josephine Rose, their base and Battle Skipper storage facility, further symbolizing her inherited duty to safeguard the technology.
