Description
Hina Sorasaki leads the Disciplinary Committee as a third-year student at Gehenna Academy. Her role necessitates strict enforcement of school rules and decisive battlefield judgment, earning her a feared reputation among students and opposing organizations. Off-duty, she displays a relaxed and gentle demeanor, frequently expressing that managing regulations feels bothersome. This contrast reveals a complex personality—externally detached yet internally weighed by responsibility.

Her appearance features knee-length white hair secured by a black and red ribbon, dark horns marked with purple cracks, and a golden monocle clip. Long black wings extend from her back, accompanied by a distinctive jagged black cylinder halo adorned with purple accents, resembling a solid crown. She wears a dark purple military uniform with gold embellishments, a black skirt, thigh-high stockings, and combat boots, wielding a customized MG42 machine gun with a violet grip and a barrel emitting purple light.

In combat, she dominates through area control and rapid response. Her primary attack unleashes significant damage across a wide fan-shaped area, scaling with proficiency. Additional abilities include instant reloads upon ammunition depletion, temporary attack boosts, increased attack speed, and heightened damage against exposed targets, cementing her reputation for overwhelming battlefield effectiveness.

Her background includes pivotal involvement in Kivotos events. During Eden Treaty negotiations, she advocated for Gehenna's acceptance, hoping it would stabilize the academy and permit her retirement due to exhaustion. An explosion at the signing ceremony, orchestrated by Arius Squad, trapped attendees. While protecting Sensei amidst the chaos, she sustained severe injuries and collapsed after confronting hostiles. This failure, compounded by chronic stress, triggered an emotional breakdown where she confessed feelings of inadequacy next to peers like Hoshino who endured trauma yet persevered. She admitted craving acknowledgment and praise for her efforts, mirroring what Sensei offered others. After Sensei expressed gratitude for her dedication, she regained composure and continued supporting defense operations.

The 1.5th Anniversary Short Animation depicts her responding to a mall crisis during a summer sale. Automated turrets incite chaos, prompting her to collaborate with students from the Foreclosure Task Force and Hyakkiyako Alliance Academy to neutralize the threat, showcasing her leadership in uniting diverse groups during emergencies.

Her development underscores the struggle between duty and personal fatigue, culminating in a pivotal moment of vulnerability and reaffirmed resolve following earned recognition.
