Shie Hassaikai Arc
After the Provisional Hero License Exam, Class 1-B meets 1-A in the hallways, and Neito takes the opportunity to reveal that all 1-B students have passed the exam.

Joint Training Arc
Kinoko 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, Kinoko is paired up with Itsuka Kendo, Shihai Kuroiro, and Manga Fukidashi to face Class 1-A team consisting of Momo Yaoyorozu, Fumikage Tokoyami, Toru Hagakure and Yuga Aoyama in Round 2.

Before the round begins, Itsuka devises a strategy to defeat Class 1-A. Itsuka's first plan is to use Shihai to attack their rivals with Dark Shadow. If this fails, Itsuka predicts the others will use light. This will be the signal for plan b. The light gives away Class 1-A's location, giving Manga and Kinoko the opening to barrage Class 1-A with their long-ranged Quirks.

After Shihai failed to capture Yuga, Kinoko started to use her Mushroom Quirk to spawn mushrooms everywhere. Using her spray bottles and Manga's quirk, the mushrooms begin to grow more rapidly. This not only gives Shirai more chances to hide but it also causes serious problems for Momo and her teammates by growing mushrooms all over their bodies. Taking advantage of the situation, Itsuka's team manages to isolate Momo from the rest of his team, and Shirai captures Yuga and eliminates him from the match.

While Momo faces Itsuka alone, she manages to create and send to Fumikage and Toru ethanol to get rid of the mushrooms. She also send infrared goggles for Fumikage. Thanks to this device, Fumikage locates the position of Shirai and Kinoko and strikes them both with Black Ankh Sabbath before they have time to react.

It seems that Fumikage has defeated the two students, but when he prepares to take them to jail, he starts coughing. Kinoko reveals that she can grow mushrooms inside a person's windpipe, although it's a skill she admits doesn't like to use. Because of this, Fumikage is captured and caged along with Yuga, and they are soon joined by Momo and Toru after they are captured by Itsuka, giving class 1-B the victory of that round.

With the match over, Kinoko apologizes to Fumikage and offers him a throat lozenge to help the pain caused by her mushrooms growing in his throat, but he refuses her pity. After this, Kinoko stays to watch the remaining rounds along with the rest of the students. The Joint Training Battle ends with victory for class 1-A, and Kinoko cannot hide her displeasure that her class ended up being defeated.

Despite the fierce competition and the result, the exercise ends on good terms between both classes, and later Class 1-B visits Class 1-A's dormitories for socializing and dinner. Kinoko engages in a conversation with Fumikage, asking him for private pictures of Hawks.

Kinoko is worried, Midnight explains that the students just be helping a little during the initial asault, after which they can retreat.

Finally the heroes start the assault on the mansion. Members of the Paranormal Liberation Front are caught off guard due to this surprise attack, but many of them come out to face the heroes. It is in these moments when the students activate their Quirks to help the heroes. Kinoko uses her Mushroom Quirk to grow mushrooms both all over the bodies and in the throats of the foes, defeating a lot of them and giving the advantage to the heroes.

When their assistance is no longer needed. Fat Gum uses his Super Move Fataxi to carrying Juzo, Kinoko, Denki, and Fumikage in his body, taking them away from the battlefield. However, when Tokoyami sees his mentor Hawks in danger, he jumps out of Fat Gum's body and flies back. Fat Gum ejects Juzo, Kinoko, and Denki from his body and tells them to run the rest of the way before running off to stop Tsukuyomi.
