Yaiba Shirogane, a 16-year-old class representative at Otogi All-Girls High School, sports short wavy hair and her school uniform as her signature look, though her *High School Days* spin-off incarnation trades these for green pigtails. Her narrative revolves around an earnest crush on the brusque Ginga, driving her to seek romantic advice from Nasa Yuzaki. Unprepared for such counsel, Nasa enlists his wife Tsukasa, who jests that love is a “war of the minds.” The trio’s clumsy reconnaissance mission—shadowing Ginka—spirals into chaos when he is spotted with Aya Arisugawa, triggering Shirogane’s panicked retreat. After clarifying the interaction as accidental, Nasa urges Shirogane to confront her feelings openly. Her resolve culminates during Ginga’s tense encounter with a stalker in a shadowed alley, where she blurts, “I… Really like you!!”—a vulnerable yet defiant act that arcs her evolution from timid admirer to bold confessor.
