"My Hero Academia" is set in a world where superpowers, known as "Quirks," have become commonplace, with nearly 80% of the population possessing unique abilities. The story centers on Izuku Midoriya, a Quirkless boy who dreams of becoming a hero despite his lack of powers. His life changes when he encounters All Might, the world's greatest hero, who passes on his Quirk, "One For All," to Midoriya after recognizing his courage and determination. This power, which can be transferred from one user to another, grants immense strength but requires rigorous training to master. Midoriya enrolls at U.A. High School, a prestigious academy for aspiring heroes, where he faces intense training, academic challenges, and rivalries with classmates, particularly Katsuki Bakugo, his childhood friend-turned-rival. The series explores Midoriya's growth as he learns to control One For All, navigates complex relationships with peers like Shoto Todoroki and Ochaco Uraraka, and confronts the moral dilemmas of heroism. Alongside his classmates, Midoriya trains to combat villains while uncovering the secrets of One For All and its connection to All Might's nemesis, All For One, a powerful villain who can steal and distribute Quirks. The narrative balances episodic school life and high-stakes battles, with students participating in events like the U.A. Sports Festival and internships with professional heroes. Simultaneously, the League of Villains, led by Tomura Shigaraki and supported by All For One, emerges as a persistent threat, challenging the heroes' ideals and forcing them to confront the darker aspects of their society. Themes of perseverance, legacy, and the responsibilities of power are woven throughout the story, as Midoriya and his peers strive to become symbols of hope in a world where the line between hero and villain is often blurred.
