Principal Nezu and the staff did a test to see how the students trust one another by telling them who was a traitor. Izuku decided to volunteer for this experiment. When Nezu revealed that Izuku was the traitor, most of his classmates turn against him except, Katsuki, Kirishima Shoto, Class 1-B (minus Neito), Mei, Ochako, Momo, Eri, Jirou Shinsho, Koda, The Big Three, and the Pro Heroes. Even Ashido and Hagakare believed that Izuku was the traitor and cheated on him with Kaminari and Sero. Nezu and the staff revealed that it was a test to see if they trust each other and all of 1-A minus Katsuki, Ochako, Momo, Koda, Shoto, and Jirou failed. 1-A felt guilty and want to apologize to Izuku, but Izuku already left and headed to North America. Nezu told them that he was given some time off. After a year, Izuku returned back to U.A with a new look, power, and attitude. Along with him are two girls he had met while he was in North America with his family.
