Reon Misono is a first-year Literature student at Kamogawa Music College, where he studies alongside peers like Yuto Goryo and Wataru Matoba following his transfer. He serves as a guitarist in the band GYROAXIA. Possessing a stubborn yet exceptionally patient personality, Reon exhibits a fierce work ethic and unwavering determination, practicing relentlessly until he masters his skills.

He maintains a complex dynamic with GYROAXIA's vocalist, Nayuta Asahi, whose dictatorial leadership he staunchly opposes. Despite this friction, Reon recognizes the band's collective talent and holds a firm belief that they deserve to reach the top. He stands as the sole member willing to directly challenge Nayuta, though he often measures his challenges carefully due to the vocalist's unpredictable nature.

Reon's commitment to GYROAXIA is absolute. He dismisses any suggestion of quitting, resolved to remain until Nayuta acknowledges his abilities. He asserts that any departure would be solely on his own terms, driven by his refusal to be dominated. This determination fuels his rigorous practice sessions, especially after band disagreements, where he channels frustration into his guitar playing, viewing conflicts as catalysts for mutual growth.

Physically, he stands 177 cm tall, weighs 63 kg, and has deep violet hair with striking golden eyes. Born on January 30th, he is an Aquarius. He favors urban environments and enjoys croissants from stand-up soba bars, while disliking cold weather and referring to an unspecified individual as "that idiot." For GYROAXIA's participation in the LIVE ROYALE FESTIVAL, he relocated to Nishishinjuku, Tokyo.
