You live in a world where 80% of the population has quirks. You can decide what your role is in this world; maybe you're a hero, fighting to make this world a better place. Maybe you were born with a dangerous quirk, or went through some hard times and are one of the top villains fighting for what you think is a 'better cause'. Maybe you're striving to become a hero, and have become a student at UA high school, or maybe you've chosen to help students become heros as a teacher at UA, or maybe you're a normal citizen, quirkless or not. The possibilities are endless and remain in the palm of your hand!
