Midori Ichinotani, a student at Saint Katarina Academy, stands as the tallest and most composed member of her close-knit trio. Hailing from considerable wealth, her residence houses an arsenal of weaponry, complementing her technical expertise in areas like vehicular operation and sharpshooting. These skills, however, prove insufficient when the academy’s chairman orchestrates her abduction, intending to seize her advanced airship and auction it to finance a new campus structure.

Her capture sparks a high-stakes rescue by her friends, who commandeer a dormant war machine from her estate and navigate its complexities under pressure. The chairman counters their efforts with henchmen clad in animal costumes, creating chaotic obstacles. While Midori’s confinement sidelines her from active confrontation, her curated arsenal and ownership of cutting-edge technology remain pivotal to the mission’s unfolding.

Her background as a shrewd heiress is defined by privilege and preparedness, with the airship serving as both a symbol of her resources and a linchpin in the chairman’s scheme. The events pivot around her strategic value as a catalyst, though her agency beyond initiating the rescue remains unexplored in documented accounts.
