Akoya Gero, a second-year student council secretary and treasurer, boasts waist-length wavy light pink hair and piercing blue eyes. His noble yet narcissistic demeanor drives an obsession with elegance, dismissing mundane concerns as beneath him. Aligned with Conquest Club members Kinshiro Kusatsu and Ibushi Arima under extraterrestrial commander Zundar’s orders, he transforms into Perlite, the Pearl Chevalier, commanding nature-based abilities tied to blooming flowers.

Initially clashing with classmate Ryuu Zaou through biting insults and mutual frustration over Ryuu’s crass behavior, their rivalry softens into teasing chess matches in later episodes, reflecting budding camaraderie. Interactions with Ibushi oscillate between platonic reverence in the main series and subtle romantic tension in spin-off media, hinting at unspoken depths.

Akoya’s self-absorption falters around Io Naruko, whom he respects and flusters near when aided after scuffling with Ryuu, revealing unexpected vulnerability. While his vanity and loathing for vulgarity persist, his role evolves across narratives: once an antagonist, he reluctantly allies with the Earth Defense Club in select missions, balancing cooperation with unwavering haughtiness.

Born April 24 (Taurus, blood type B, 179 cm), his aristocratic poise and aesthetic fixation starkly contrast the Earth Defense Club’s disorder, crystallizing themes of beauty and refinement through his design and narrative presence.
