Takuya Isurugi, a teenaged aviation mechanic with black hair cropped at ear length and dark eyes, serves in an all-female aerial demonstration squadron originally branded a disciplinary unit for misfits. Exuding relentless optimism and fueled by a fervent passion for aircraft, he dedicates himself to maintaining the squadron’s fleet. His otaku hobbies manifest in a personal space cluttered with collectible figures and memorabilia, contrasting his professional rigor.

His arrival unintentionally ignites a romantic rivalry between pilots Miyuki Haneda and Arisa Mitaka. Miyuki, courteous and rule-bound, initially misjudges him as a pervert after an awkward encounter but slowly warms to him. Arisa, brash and driven, first dismisses him only to later compete for his attention, heightening their existing friction. Takuya navigates the tension with humor, quipping, "One will be my girlfriend, the other will be my mistress!" Despite the chaos, he supports both women, mediating clashes to preserve squadron unity.

As a skilled mechanic and aviation devotee, Takuya becomes a linchpin for teamwork, striving to elevate the squadron’s performance. Convinced their shared zeal for flight can bridge personal rifts, he battles mounting external pressures to disband the group over perceived inefficiency. His efforts to bolster morale and collaboration prove vital to their survival.

Unresolved flashbacks hint at parallels between his predicament and a past love triangle involving Captain Mitsuru Konishi, though Takuya’s romantic entanglements remain open-ended. His arc prioritizes team stability over self-growth, blending comic relief with earnest gestures—like tending to a sick Arisa—amidst fraught dynamics.

Born April 11 under the Aries sign, his youthful looks and cheerful demeanor render him approachable yet occasionally naive, traits that both endear and challenge him within the squadron’s high-stakes world.
