Toru Hagakure

Invisible Girl: Class 1-A's cheery invisible student, who uncovered the U.A. traitor.

Toru Hagakure, hero name Invisible Girl, is a cheery and outgoing Class 1-A student from Tokyo whose Quirk Invisibility makes her entire body invisible and lets her refract light. Because of the Quirk her features have been only partially revealed in the series, and her hero uniform consists of nothing but a pair of gloves and boots to maximize her stealth.

Background

Like Tsuyu, Toru was originally going to be male, but Horikoshi made the character female because Class 1-A lacked female students and because a girl with an invisible body struck him as a funny concept. She has described her face as "a combination of Yang Guifei and Francis Xavier". Aggressively sociable, she appears to like shopping, and her room suggests a fondness for plushies and other cute things.

In battle she believes that taking off her clothes is a tactical advantage, to the embarrassment of everyone around her, yet she seems unaware of what being invisible means, showing slight embarrassment at the idea of being seen undressing even in her hero costume.

During the U.A. Traitor Arc Toru proves observant, noticing that Yuga has not been himself since Izuku's return to U.A.; her curiosity leads her to discover that he is the traitor who, painfully and unwillingly, has been passing intel to All For One. She is also emotionally fragile: after reprimanding Yuga for betraying his classmates she cries over how he had the gall to attend classes with them, and again during his interrogation.
