Yosetsu Awase/Synopsis

U.A. Sports Festival Arc
Yosetsu finished the Obstacle Race in 12th place, allowing him to continue onto the next event. He forms a team with Tetsutetsu Tetsutetsu, Ibara Shiozaki, and Juzo Honenuki.

At the beginning of the event, Tetsutetsu's team attacks Izuku Midoriya's team with Juzo using his Quirk to trap them, but Izuku uses his jet pack to escape. Tetsutetsu's team attacks again, but this time is blocked by Fumikage Tokoyami's Dark Shadow. Tetsutetsu's team fails to qualify for the final event. Tetsutetsu is confused on how they lost all their points, and Ibara remarks that it was possibly a punishment for taking Minoru Mineta's headband in such an unfair way.

Forest Training Camp Arc
When Class 1-B arrives at the training camp, their homeroom teacher explains to them that they will be extending their Quirks and that the more they use their Quirk, the stronger they will be by breaking their limits. When Class 1-B witnesses Class 1-A's training, Yosetsu is taken by surprise. Itsuka Kendo asks Shota Aizawa how they can observe everyone, and he explains that that is the reason the Wild Wild Pussycats are around.

During the third day, the Vanguard Action Squad attacks the camp, filling the forest with gas and fire. Yosetsu runs into Momo Yaoyorozu, and they are attacked by the Chainsaw Nomu, who injures Momo. Yosetsu carries her as he runs from the Nomu, which cuts down several trees with it's multiple weapon arms consisting of hammers, drills, and chainsaws. Momo apologizes to him for dragging his speed down. The Nomu reaches them and is about to attack them with one of it's chainsaw arms. Yosetsu braces himself for the blow, but the Nomu's arm stops and all of it's arms retract into it's body as it begins walking toward the Vanguard Action Squad's rendezvous point. Momo realizes that it is being called back because the villains have captured Katsuki Bakugo. Thinking of a plan, she creates a tracking device and asks Yosetsu to weld the button onto the Nomu. He runs after it and bonds the device onto the Nomu's back. As it walks away, Yosetsu and Momo decide to continue running.

U.A. Cultural Festival Arc
His next appearance is before the U.A. Cultural Festival when he whacks a trash-talking Monoma with a piece of the dragon prop Class 1-B uses in their play. He apologizes to Izuku, Eri, and Mirio and explains that Kendo wasn't with him because she was forced to enter the Beauty Contest. Yosetsu later makes a comment about either Kendo or her dress looking sexy. He takes part in Class 1-B's play.

Awase participates in the fourth match of Class 1-A and 1-B's joint training, with Setsuna Tokage, Kojiro Bondo, and Togaru Kamakiri against Kyoka Jiro, Katsuki Bakugo, Rikido Sato, and Hanta Sero.
