Sports Festival Arc
He finishes the obstacle race, placing 12th,  allowing him to continue onto the next event, the Human Cavalry Battle. He forms a team with Tetsutetsu, Juuzou and Ibara.

At the beginning of the event, Tetsutetsu's team attacks Izuku's team with Juuzou using his Quirk to trap them, but Izuku uses his jetpack to escape. Tetsutetsu's team attacks them again, but Fumikage's Dark Shadow blocks them off. After the Human Cavalry Battle ends, Tetsutetsu's team fails to qualify for the final event, with Tetsutetsu confused as to how they lost all their points, and Ibara remarking that it is possibly punishment for taking the dwarfy kid's headband in such an unfair way.

School Trip Arc
When Class 1-B arrives at the training camp. Homeroom teacher Blood King explains they'll be extending their Quirks and the more they use their Quirks the stronger they'll be by breaking their limits. When Class 1-B witness Class 1-A's training. Yousetsu is taken by surprise. Afterwards Itsuka Kendou asks Shouta Aizawa if can they observe everyone, he explains that's the reason The Pussy-Cats are around.

During the third day, the Vanguard Action Squad attacks the camp, filling the forest with gas and fire. Yousetsu runs into Momo Yaoyorozu. However, they are attacked by the Vanguard Action Squad's Noumu and in the process, Momo is badly injured. Yousetsu carries an injured Momo with him while running away from the Noumu. The Noumu cuts several trees down with its multiple weapon arms consisting of chainsaws, drills and hammers to get to Yousetsu. The injured Momo apologizes to Yousetsu for dragging his speed down. The Noumu reaches Yousetsu and is about to attack him with one of its weapon arms. Suddenly, the Noumu's chainsaw arm stops; the Noumu retracts its weapon arms into its body and begins walking back to the Vanguard Action Squad's rendezvous point. Momo realizes that the Noumu is being called back because the villains have captured Katsuki Bakugou. Thinking of a plan, Momo creates a button (which appears to be some sort of tracking device) and asks Yousetsu to weld the button onto the Noumu. Yousetsu does what Momo asked and uses his Quirk to bond Momo's button onto the Noumu. As the Noumu walks away with Momo's button stuck on it, Yousetsu and Momo decide to make a run for it.
