Reon Misono, a first-year Literature student at Kamogawa Music College, stands at 177 cm tall and weighs 63 kg. His distinctive violet hair and golden eyes mark his appearance, and his birthday falls on January 30th (Aquarius). He finds energy in bustling city streets and savors croissants from stand-up soba bars, yet he harbors a distinct aversion to cold weather and frequently refers to an unspecified individual as "that idiot."

As GYROAXIA's guitarist, Reon exhibits a stubborn nature tempered by exceptional patience. He embodies persistence, practicing relentlessly until mastering any skill. Within the band, he stands as the vocal counterpoint to vocalist Nayuta Asahi's dictatorial style, openly challenging Nayuta's decisions. Despite this friction, Reon firmly believes in GYROAXIA's exceptional collective talent and their deserved place among top-tier bands. He remains the sole member willing to confront Nayuta directly, though he often exercises restraint due to Nayuta's unpredictable reactions.

Academically, Reon shares the Faculty of Literature with peers from other bands: Yuto Goryo, Wataru Matoba, Futa Kaminoshima, Yamato Tsubaki, and Aoi Wakakusa. This shared environment hints at interactions beyond music. His history includes a high school band with Yuto Goryo before their paths diverged, forming the basis for their current rivalry as members of competing bands.

The kanji in his name reflect facets of his character: "Reon" (礼音 - thankful/sound) and "Misono" (美園 - beautiful/garden). Throughout his journey, Reon navigates a complex loyalty, consistently criticizing Nayuta's methods while demonstrating unwavering commitment to GYROAXIA's ultimate success, prioritizing the band's collective potential above personal disagreements.
