Toru Hagakure's permanent invisibility Quirk renders her body completely undetectable to the naked eye. She becomes visible only through her clothing or accessories, initially her hero costume's light blue gloves and lace-up shoes, later upgraded to combat-ready gloves and knee-high boots for winter operations. Objects not in direct contact with her skin also vanish, requiring nudity for maximum stealth effectiveness, a tactical choice that sometimes creates awkward situations despite her general lack of self-awareness about her power's implications. A partial glimpse of her appearance occurred during the refraction of Yuga Aoyama's Navel Laser, revealing chartreuse hair with pink streaks, thick eyelashes, and large heterochromatic eyes blending teal and yellow. This incident exposed a vulnerability: intense light manipulation can temporarily disrupt her invisibility. Years after the Final War, she adopted a specialized suit to maintain decency during such Quirk malfunctions, though her mature appearance remains unspecified. Her personality blends bubbly enthusiasm with perceptiveness. She actively participates in class activities, encouraged peers during the U.A. Sports Festival cheerleading event, and enjoys socializing and shopping. Her dorm room, filled with plush toys, reflects an affinity for cute items. Despite her lightheartedness, she demonstrates emotional depth, notably when discovering Aoyama's forced betrayal of Class 1-A. Initial anger and tears during his confrontation evolved into concern for his safety, highlighting her compassion. This emotional fragility resurfaced when she sobbed on Mashirao Ojiro's shoulder post-interrogation. Toru's combat abilities prioritize stealth and teamwork. Her Quirk facilitates espionage, enabling her to evade sensory detection—even from Mezo Shoji—and gather intelligence, as seen uncovering Aoyama's traitor status. Offensively, she employs surprise attacks using punches or kicks, compensating for low physical strength. Training under Yoroi Musha enhanced her Quirk's photokinetic applications, leading to Ultimate Moves like "Warp Refraction," redirecting sunlight to blind foes, and "Warp Refraction: Navel Laser," a collaborative technique with Aoyama amplifying his lasers into wide-area blasts. These skills proved crucial, such as neutralizing the villain Kunieda during the Final War. Her narrative role evolved from comic relief to pivotal support. Early arcs showed her in supportive capacities: failing the Battle Trial against Shoto Todoroki's area-of-effect ice attack, aiding evacuations on Nabu Island, and being hospitalized after the Forest Training Camp gas assault. The "U.A. Traitor" arc marked a turning point; her stealth allowed her to witness Aoyama's confession, and she later helped deflect All For One's Omni-Factor Unleash. By the Final War, she actively contributed to victories through coordinated light-based assaults and espionage. Post-graduation, Toru achieved the rank of No. 39 Pro Hero, indicating successful integration of her stealth and refraction abilities into professional heroics. Her costume modifications reflect lessons from wartime experiences, prioritizing practicality and Quirk-stability management.
