Misato Tachibana is a high school student with a tsundere demeanor, most pronounced around classmate Koujirou Sasahara. Her romantic feelings trigger intense fluster, comically escalating into weaponized outbursts—rifles, rocket launchers, and artillery materialize in exaggerated fashion, cementing her reputation as a "gandere," a tsundere archetype fused with armaments. She sports neck-length peach-hued hair, brown eyes, and faint cheek blushes that intensify sharply at Koujirou’s mention. Her standard uniform includes knee-high socks and a ribbon-tied bow. She forms a tight trio with friends Fe-chan and Weboshi, bonding over shared secrets and lighthearted mischief, though her explosive reactions occasionally disrupt their dynamic. Misato’s younger sister, Mihoshi, contrasts her with calm composure, often prodding Misato about her temper. Despite her combative front, Misato displays subtle care—delaying departures to walk home with Mihoshi or discreetly returning Koujirou’s lost handkerchief while dismissing the gesture as mere "volunteer work." A kendo club member alongside Yoshino Naganohara, she thrives on friendly rivalry during practice bouts. Innocuous remarks often spiral as she misinterprets conversations as veiled references to Koujirou, prompting vehement denials of any romantic undertones, even rejecting hypothetical mentions of marriage or parenthood. Her childhood overlapped with Koujirou’s at a martial arts school. The surname Tachibana merges the characters for "standing" and "flower." No official media beyond the core series expands her narrative trajectory.
