**Toru Hagakure** attends U.A. High School's Class 1-A, training as a future pro hero. Her Quirk, **Invisibility**, permanently refracts light through her body, rendering her unseen. This family trait means both her parents also possess invisibility, making her their only child. Her physical form remains hidden under normal conditions, identifiable only by held items or worn attire like gloves and boots. A partial glimpse occurred when refracting Yuga Aoyama's Navel Laser, revealing chartreuse hair with pink and turquoise strands, medium-length wavy hair, thick eyelashes, and round eyes featuring teal-and-yellow irises. Her full visible appearance was later officially illustrated, depicting her as a young woman with long hair reaching her waist. Her hero costume includes light blue gloves and white boots to minimize visibility, though full invisibility requires nudity, leaving her exposed to environmental hazards or attacks. Post-graduation, she wears a specialized yellow bikini-style suit for decency should her Quirk malfunction. Toru exhibits a **bubbly, cheerful, and socially eager personality**. She radiates optimism, frequently encouraging classmates during stress, like leading Sports Festival cheerleading. She delights in shopping, cute items such as plush toys, and discussing romance with peers. Despite her invisibility, she shows self-awareness about nudity, expressing embarrassment when undressing near others like Mashirao Ojiro. Her observant nature detects behavioral shifts in classmates, and she displays emotional vulnerability, crying after confronting Yuga Aoyama about his betrayal. While her Quirk often serves comic relief, she demonstrates strategic thinking by leveraging stealth for tactical advantages. Her **hero training** emphasizes espionage and light manipulation. Invisibility enables undetectable movement, ideal for ambushes, evasion, and intelligence gathering. She developed techniques to bend light, creating blinding flashes named **"Warp Refraction: Say Cheese!"** During the Provisional License Exam, she harnessed sunlight for this, later refining it to redirect light-based attacks like Aoyama's lasers in collaborative moves such as **"Warp Refraction: Navel Laser."** Training under Yoroi Musha enhanced these photokinetic abilities, focusing on offensive and defensive applications. Her combat style merges stealth with melee strikes, exploiting invisibility for surprise. Drawbacks include the Quirk's permanence, potential detection via thermal imaging, and the vulnerability from necessary nudity. Rarely, excessive light absorption causes temporary visibility glitches. Her **development** spans key arcs. Early at U.A., partnered with Ojiro in the Battle Trial, she was defeated by Shoto Todoroki and Mezo Shoji. During the U.S.J. attack, transported to the landslide zone with Todoroki, she remained unnoticed while he fought villains. At the Sports Festival, she ranked 38th in the Obstacle Race and led an unsuccessful cavalry team. She later adopted the hero name **"Stealth Hero: Invisible Girl"** and began workplace training. Significant growth occurred during Final Exams, where she and Shoji defeated Snipe by using her stealth to handcuff him. Forest Training Camp focused on enhancing concealment, though Mustard's gas incapacitated her during the villain attack. Her most significant contribution came during the **"U.A. Traitor" investigation**. Initially suspected due to her espionage-suited Quirk, she uncovered Aoyama’s coerced betrayal by stealthily witnessing his communication with All For One, leading to his exposure and her emotional confrontation. In the Final War, she aided Nabu Island evacuations and defended against All For One’s Omni-Factor Unleash by refracting its light. Eight years post-war, she graduated as the **No. 39 Pro Hero**. **Trivia notes**: Her original design was male, changed to address gender imbalance and comedic potential. The surname "Hagakure" means "hidden in leaves," referencing historical and literary themes. Her favorite food is caramel, and she enjoys hidden-camera shows. Official stats rank her low academically in Class 1-A but high in cooperativeness.
