In a world where most of the population is gifted with special powers known as "Quirks", Izuku Midoriya is a young boy who always dreamed of becoming a hero, despite not having a Quirk himself, until one day he is attacked by a villain made of sludge and is rescued by none other than All Might, the best hero in the world and his idol since childhood. After seeing Izuku is safe, All Might starts leaving with the villain in his custody, but Izuku grabs onto his leg and ends up flying with him. Aft
Izuku discovers that All Might's true form is that of a frail, emaciated man who suffered a massive respiratory injury 5 years ago, preventing him from using his powers for longer than 3 hours a day. All Might tells Izuku that he should give up on being a hero and focus on a more realistic dream. Disheartened, Izuku makes his way home, only to see his classmate and bully Katsuki Bakugo attacked by the same sludge villain that All Might captured, who escaped when Izuku latched onto All Might.

All Might tells Izuku of his Quirk, "One For All", a sacred torch that transfers its strength from person to person, increasing its strength each time it is passed. While All Might believes Izuku to be worthy of his Quirk, bestowing it to him right away would ruin his untrained body. All Might then designs a ten-month training regimen to ensure that Izuku can become a vessel that can carry it. After ten months of intense training, Izuku's body becomes more refined and muscular, with All Might no
After receiving All Might's Quirk, Izuku attends the exams for the prestigious U.A. High School for heroes in training. Izuku's lack of experience causes him to quickly fall behind the others until one of his fellow examinees, Ochaco Uraraka, finds herself in serious danger and he runs to her rescue. He manages to use One For All to unleash a powerful punch that instantly destroys the giant machine, but the sheer power of the attack also breaks his arm in the process. One week later, Izuku recei
Izuku begins his first day at U.A as a member of Class 1-A along with Bakugo and Ochaco. The homeroom teacher, Shota Aizawa, holds a physical test to evaluate how the students use their Quirks, threatening to expel the worst ranked student. Unable to use his Quirk more than once without breaking his bones again, Izuku only has one shot to get a good score during the pitching test. He throws his pitch, and at the last second, he concentrates One For All through his fingertips. The explosive throw
The Quirk Apprehension Test ends with Izuku ranked last, However, Aizawa reveals the expulsion rule was a ruse to bring out the best in the class, much to the students' shock. The next day, Class 1-A undergoes their Hero Basic Training class where All Might is the teacher. Now donning their own hero costumes, the students are assigned to a mock battle between teams of two to test their combat abilities. Izuku is paired with Ochaco, who he has since befriended and his opponents are Tenya Ida and
A flashback shows that "Deku" and "Kacchan" grew up in the same neighborhood and have known each other since they were little kids. Bakugo was always surrounded by praise for his innately powerful explosion Quirk, causing him to always feel superior to everyone around him. However Izuku still never treated Bakugo like he was better, and even tried to help him after he fell into a river. Bakugo only took this as an insult, like Izuku, despite being Quirkless, was looking down on him. That same an
As Izuku is taken to the nurse's office to heal, Bakugo watches the rest of his classmates battles and becomes intimidated by how strong some of his peers Quirks are. After recovering from his injuries, Izuku attempts to cheer him up, to the point of sharing parts of his secret with Bakugo. However, Bakugo refuses to believe him and responds by admitting defeat. Before storming off, he warns Izuku that he is just getting started, and will not lose again. All Might arrives to console Bakugo again
During Class 1-A's homeroom class, Mr. Aizawa announces that the class needs to elect a representative which gives a chance for students to gain extra recognition. Much to his surprise, Izuku is chosen as the class president by popularity, but he ends up relinquishing the position to Ida when he and his friends find him more suitable for the position. Class 1-A is assigned to another field exercise where they meet the famous rescue hero Thirteen. She greets them and shows the students around her
The Warp Villain, Kurogiri, uses his powers to scatter the students throughout the facility in order for the other villains to ambush them to attract the attention of All Might for a trap. Izuku ends up stranded in underwater and surrounded on a ship along with his classmates Tsuyu Asui and Minoru Mineta. Despite being heavily outnumbered, the three coordinate their powers to defeat the vilains and escape the area. At U.A. in the nurse's office, All Might tries to contact Thirteen and Aizawa but
As the students continue to fight for their lives against the League of Villains, both teachers are defeated by the strongest amongst the villains. Ida eventually manages to escape with his friends' help to call for backup from U.A. Knowing that their group cannot fight off reinforcements, the villains plan to retreat. Before beginning their escape, the League of Villains' leader Tomura Shigaraki attempts to kill the nearby Izuku, Tsuyu and Mineta but is interrupted by the appearance of All Migh
After All Might's arrival at U.S.J., Shigaraki unleashes his secret weapon, the Multi-Quirk monster called "Nomu" against All Might, who finds himself struggling to inflict any substantial damage on the monster. All Might pushes himself beyond his limits to overwhelm Nomu's Shock Absorption and Regeneration Quirks with numerous rapid full power attacks until he is launched outside the facility and knocked out much to the students awe. He declares that the League of Villains are finished, much to
Although he was able to defeat the Nomu, All Might has no energy left and is defenseless against Shigaraki, but Izuku manages to stall the enemy long enough for the other teachers to arrive and force him and Kurogiri to retreat. As the leftover villains are captured and the students are rescued, All Might thanks Izuku for saving his life but warns that fighting past his limit has reduced his power limit to only an hour a day. Shigaraki confers with his master, implying that their feud against th
