Final Exams Arc
Koji is paired with Kyoka and they must face Present Mic within 30 minutes in order to win and pass the test. The test begins.

Present Mic uses his loud voice to keep Kyoka and Koji off guard. Annoyed by Present Mic's loud voice, Kyoka tells Koji to command the nearby animals to attack, but Koji is unable to due to Present Mic's voice being too loud, in addition to it likely having already scared off the wildlife.

Kyoka and Koji manage to get a little closer to the escape gate, but Kyoka notes that Present Mic will be at the escape gate and that no matter what option of victory they choose, a standoff is inevitable. Present Mic uses his loud voice again; Kyoka notes that they cannot get any closer as long as Present Mic is using his Quirk. Kyoka sees an ant and comes up with an idea; she asks Koji if he can control bugs, but his terrified reaction indicates that he doesn't like bugs. Present Mic uses his loud voice once again; Kyoka tries to counteract with her Earphone Jacks' but the sound of her heartbeat doesn't do anything against Present Mic.

Present Mic continues using his loud voice against Kyoka and Koji who are unable to handle it. Out of options, Kyoka asks Koji if he can control insects to which he approves. Kyoka uses her Earphone Jacks to break a rock, which reveals dozens of insects, much to Koji's terror. Kyoka tells Koji that she understands his phobia but using the insects to attack Present Mic is the only plan she can think of because their opponent is too strong. Kyoka encourages Koji to follow through with her plan.

After seeing Kyoka's bleeding ears, Koji is ashamed that he is running away from this fight and realizes that he can only continue being at U.A. by overcoming his fear. Koji musters up his courage and though trembling with fear, he commands the insects to attack Present Mic while Kyoka is annoyed, he picked that moment to talk. At the escape gate, Present Mic sees that time is nearly up. Suddenly, dozens of crawling insects break out from the ground near his left leg, and he realizes that the insects traveled to him by moving underground; a place where sound is ineffective. Present Mic is paralyzed in fear when the insects swarm onto his leg and cause him to faint in horror, allowing Koji to run through the escape gate while carrying an injured Kyoka in his arms.

Back in class at U.A., Koji learns that he passed the written test and will go with his classmates to the forest lodge which is a boot camp. Koji along with his class go to Kiyashi Ward Shopping Mall to buy necessities for the forest lodge.
