U.A. Beginnings Saga

The Yuuei Beginnings Saga is the introductory saga of the series. Izuku Midoriya, a young boy who was born without a Quirk, dreams of getting one some day. At the beginning, he is bullied by Katsuki Bakugou and inherits All Might's Quirk. Izuku is accepted into Yuuei Academy and meets a lot of other heroes.

The saga talks about how one day a Luminescent Baby was born in Quig Quig, China and had a "individuality". Soon everyone across the world would get what they call a Quirk or a special power. These powers would then let people become heroes or villains.

The saga also happens when Izuku starts Yuuei and has to meet the expectations of the school.

We are introduced to two of the major villains in the series, Shigaraki Tomura and

Kurogiri. Their goal is to kill All Might so there will be no peace.

The Sports Festival starts and helps the students show off their Quirks and skills. Katsuki Bakugou becomes the Sports Festival Champion after defeating Shouto Todoroki.

After the Sports Festival, the students of Class 1-A get to train with Pro Heroes. Izuku trains with Gran Torino to control his Quirk. While out on training, they are attacked by three Noumus and Stain. Tenya Iida, remembering what happened to his brother at the hands of the Hero Killer, wants to get revenge on Stain for hurting his brother. Stain is defeated and Tenya regrets what he did.

The End of the Term is here before the summer break, so the students have to fight against the teachers at Yuuei.

Aizawa now announces a school trip to help the students improve their Quirks and Teamwork skills. The League of Villains then attacks the students and wants to capture Katsuki, turn him into a villain.

All the Pro Heroes gather together, and form a team to raid the League of Villains hideout and rescue Katsuki. Izuku and others go undercover in order to find Katsuki and bring him back.
