Setting: My Hero Academia is set in a world where about 80% of the human population has gained superpowers called "Quirks" (個性, Kosei) as a result of recent human evolution. Quirks vary widely and have the possibility of being genetically inherited. Quirks range from being small in scale to being god-like abilities. Most Quirks have some drawback when using it, such as a usage limit or self-injury, or manifest as permanent physical mutations to a person's body. Quirks will generally manifest in an individual just after their toddler years. As Quirks became dominant among the population, and newer Quirks became more powerful, society melded around their existence and largely commodified around them. Initially, many people were inspired by old comics to use their Quirks to deal with crime on their own were recognized as Vigilantes (ヴィジランテ, Vijirante). The Hero Public Safety Commission (ヒーロー公安委員会, Hīrō Kōan Iinkai) was later formed and enlisted vigilantes to deal with criminals who abuse their Quirks, commonly known as Villains, until the Commission became more organized and instead focused on recruiting Pro Heroes (プロヒーロー, Puro Hīrō), who cooperate with authorities in rescue operations and apprehending villains. Vigilantes still exist in the present, but are considered illegal despite the help they give. Heroes work out of Hero Agencies, which serves as their base of operations and a means for them to operate a business. Heroes can either lead their organization with lower-level sidekicks, or work equally as a team. In addition, Heroes who excel in their duties gain celebrity status and are ranked in popularity via the Hero Billboard Charts, with higher ranking heroes receiving public appeal. Pro Heroes exist around the world, with the first reported Quirk being in China, and the United States being referred to as the birthplace of Heroes. Pro Heroes begin their initial training in high school, of which U.A. High School in Shizuoka Prefecture, Japan, is considered one of the most prestigious. Hero Courses offer both regular schooling and Hero-specific courses such as combat and rescue operations, as well as how to meld their individual skills and overcome their drawbacks. Companies sponsor the students, mainly by designing and remodeling superhero suits and support gear for them, and Pro Heroes often scout students for internships with them. interns with a Provisional Hero License and graduates start off as sidekicks, but can go independent to form their own offices.
