Synopsis

Sports Festival Arc

Kosei comes in 23th place during the Obstacle Course. He teams up with Neito Monoma, along with 2 other Class B students. When Katsuki Bakugo attacks from above, Neito warns him about the danger, causing Kosei to create a solidified air wall, which stops Katsuki. However, Katsuki breaks the wall and grabs two of Neito's headbands.

School Trip Arc

On the day of the forest lodge trip, when Neito Monoma mocks Class 1-A, Kosei is seen observing.

When Class 1-B arrives at the training camp. Homeroom teacher Sekijirou Kan explains they will be extending their quirks and the more they use their quirks, the stronger they will be by breaking their limits. When Class 1-B witness Class 1-A's training. Afterwards Itsuka Kendou asks Shouta Aizawa if can they observe everyone, he explains that is the reason The Pussycats are around.

After the Vanguard Action Squad start their attack, Kosei is one of the first students to be affected by Mustard's Gas, being carried by Todoroki all the time while he and Bakugo are fighting Moonfish, and chasing Mr. Compress afterward.

Quirk and Abilities

Solid Air (空気凝固, Kūkigyōko^?): Kosei's Quirk allows him to solidify air to form a wall or platform. The size of the wall or platform depends on his lung capacity. However, it seems that these walls and platforms are not strong, as Katsuki is able to break a wall as if it were made out of glass using only his bare fist, and his fist did not look injured in the slightest.
