In the Obstacle Race, Manga made it to 40th place. Before the Cavalry Battle, he decides to team up with Yui Kodai and Kojiro Bondo, forming Team Kodai. As Team Bakgou and Monoma engage in a confrontation, Manga's team interferes by Kojiro using his Quirk to stop them. However, Team Kodai is eventually knocked out of the match after they attempt to move towards Neito's Team, which causes them to fail in advancing to the tournament.
Manga and his classmates are all present when Vlad King instructs them to push themselves beyond their limits.
When Class 1-B arrives at the training camp, their homeroom teacher explains that they will be extending their Quirks and that the more they use their Quirks, the stronger they will be by breaking their limits. When Class 1-B witnesses Class 1-A's training, Itsuka Kendo asks Shota Aizawa how they can observe everyone, and he explains that is the reason the Wild, Wild Pussycats are around.
Manga and the rest of Class 1-B show up for the Joint Training Battle, with Neito loudly claiming that the momentum is now moving to their side. Upon selecting teams, Manga is paired up with Itsuka, Shihai, and Kinoko for the second match. When Shihai's plan to hijack Dark Shadow fails, he and Kinoko proceed to initiate their plan. As Kinoko spreads her mushrooms, Manga produces a large-string of Katakana using his Quirk "Comic" to separate Momo Yaoyoruzu from the rest of her team. He then augments Kinoko's mushrooms by uttering the word "ジメジメ" ("humidity") while hiding within the shadows.
Later on, Manga prevents Fumikage from chasing after Shihai, who captures Yuga Aoyama, by producing the Katakana "ピョン" ("boing") and "ギリ" ("grind"), which bounce into Fumikage as he is distracted by mushrooms growing on him. When Fumikage ambushes Team 2-B with Black Ankh Sabbath, Manga is ambushed by Toru via her Invisibility Quirk. However, Manga is quickly saved by Itsuka's intervention, which allows his team to win the match.
