Description
Azusa Shirasu attends Trinity General School as part of the Supplementary Lessons Department. Originally a dropout, her transfer to Trinity occurred under unusual circumstances—a rarity in Kivotos where academies operate as distinct nations. Her initial cold demeanor stemmed from combat training under the Arius Squad, which raised her as a mission-focused weapon. This background granted extensive knowledge of lethal tactics, including halo targeting, while leaving her devoid of hobbies or social ties. She wears a hybrid uniform: a black dress with a Trinity-Arius capelet and an Arius brooch, wielding a customized SIG Sauer M400 rifle named "Et Omnia Vanitas," engraved with the Arius motto.
Interactions with the Supplementary Lessons Department, particularly Hifumi and Sensei, gradually integrated her into student life. She formed friendships, developed interests like collecting "Momo Friends" merchandise—especially Skullman and Doctor Peroro items—and faced intense conflict between loyalty to Arius and her new bonds. Tasked as a spy to sabotage the Eden Treaty by destroying Seia’s halo, she confessed her role to the department and Sensei. They collaborated to counter Arius’ infiltration, culminating in a confrontation with her former mentor Saori—who once saved her from Arius’ punishments—beneath Trinity’s Old Cathedral. Guided by Sensei, Azusa narrowly defeated Saori, cementing her choice to protect her new life.
Azusa specializes in guerrilla warfare, demonstrating proficiency in traps, improvised explosives, and tactical combat nearly rivaling Saori’s. During one standoff, she deployed tear gas grenades and elaborate traps. Habitually vigilant, she sets nightly defensive traps around her dorm, occasionally ensnaring unintended targets. Academically, she initially scored poorly, retaking first-year courses as a second-year student. Support from Hanako and Sensei improved her grades, though recent conflicts caused setbacks.
In the 1.5th Anniversary Short Animation, Azusa appears during a mall summer sale alongside members of the Foreclosure Task Force, Make-Up Work Club, Prefect Team, and Hyakkiyako Alliance Academy. Automated turrets incite chaos; the groups collaborate to resolve the crisis, though her specific role remains undetailed.
