Kuon Ginga, a 16-year-old with light brown hair and gray eyes, holds the dual roles of second vice president in Miyagami Private Academy's Best Student Council and leader of its Covert Squad. Her expertise lies in intelligence operations, where she anticipates emerging threats and outpaces fellow vice president Nanaho Kinjo through exceptional efficiency—a skill demonstrated during her transfer interview.

Kuon initially enrolled due to undisclosed family motives. An external organization supporting her father's business coerced her into spying on the Jinguuji family's hidden powers, creating intense conflict as she grew attached to the academy, its students, and council members. President Kanade Jinguuji resolved this by refusing to disclose the sought secrets, allowing Kuon to remain and cementing her loyalty to the council while easing her struggle between family duty and newfound allegiance.

Her dynamic with Nanaho blends friendly rivalry during operational disputes with deep mutual trust and respect, evident when Nanaho expresses concern after Kuon's secret mission surfaces. Kuon defers physical confrontations to Nanaho's Assault Squad, prioritizing intelligence gathering and preemptive solutions. Her calm demeanor counterbalances Nanaho's impulsiveness, stabilizing council operations.

Hailing from a wealthy background with one-quarter non-Japanese heritage via her paternal grandfather—though specifics remain unstated—Kuon utilizes self-defense training to subdue larger opponents through throws and grapples. She directs her Covert Squad to neutralize issues before escalation, operating under President Kanade's unwavering trust. Her commitment evolves from obligation to genuine devotion, marking her transformation from reluctant spy to dedicated guardian of Miyagami Academy.
