Description
Akoya Gero is a second-year student at Binan High School who serves as both secretary and treasurer for the student council. This council doubles as the Conquest Club alongside members Kinshiro Kusatsu and Ibushi Arima. Physically, he possesses pale pink hair reaching his waist, blue eyes, and stands 179 cm tall. His personality centers on a profound appreciation for beauty and elegance, matched by a strong disdain for anything he perceives as common or unattractive. This aesthetic focus shapes his hobbies, such as aromatherapy, and his preferences, listing macarons as his favorite food while disliking nameko mushrooms and sea cucumber. He exhibits narcissistic tendencies, frequently praising his own appearance, yet demonstrates loyalty towards those he respects, notably defending Kinshiro when needed. A sensitive aspect of his past involves childhood bullying stemming from his surname "Gero," meaning "puke," which caused embarrassment and led him to jokingly introduce himself as "Holy Angel Akoya" upon joining the student council.

Within the Conquest Club, Akoya follows the orders of Zundar, an alien commander resembling a hedgehog. He transforms into Perlite, the Pearl Chevalier, using the call "Conquest!" and wields a rapier as his primary weapon. His signature ability involves creating spherical, pearl-like barriers for defense. He participates in the combined attack "Ultima Adamas" with Ibushi Arima, firing pink-hued beams from his rapier. While his initial role focused on creating monsters to challenge the Earth Defense Club rather than direct combat, he eventually engages in battles, confronting Ryuu Zaou (Battle Lover Vesta) in episode 11 of the first season.

Akoya's relationships are multifaceted. He shares a friendly dynamic with fellow Conquest Club members Kusatsu and Arima, often forming a comedic straight-man duo with Arima. He harbors a rivalry with classmate Ryuu Zaou, frequently exchanging insults; however, this dynamic evolves into more banter-like interactions in later episodes, such as them playing chess together in LOVE! LOVE! Episode 1. Akoya displays romantic interest in Io Naruko, blushing when Io helps him up after an incident, and the official otome game suggests a possible crush on Ibushi Arima.

Across various media, Akoya consistently functions as part of the Conquest Club's antagonistic force throughout the first two seasons and OVA. His relationship with Ryuu shows gradual improvement, shifting from hostility towards competitive camaraderie. The OVA focusing on third-year graduations features Akoya as a student without specific plot developments. Later seasons like HAPPY KISS! shift focus to new characters, leaving Akoya's involvement unmentioned. The 2025 series *Binan Kōkō Chikyū Bōei-bu Haikara!* has not yet detailed his role.

Trivia notes indicate his surname references the Gero Onsen hot springs, his character design draws inspiration from *Revolutionary Girl Utena*'s Utena Tenjou, and his pearl-themed name and abilities align with "akoya," a type of Japanese pearl.
