Short Summary
A teacher dressed in a hero costume and his students from another manga come to PK Academy. They try to take over the series and teach Kusuo's class what it means to be a hero.

Long Summary
After Kusuo, Shun and Riki celebrate their manga's 5th Anniversary, three characters from Asou Shuichi's older work - Our Hero Studies - show up. When Riki doesn't recognize them, Shun steps in and introduces Haganeno Ken. He describes Ken as a teacher dressed like a hero, who has shown up in the news because of his eccentric looks, as well as the brave act of rescuing students from a burning school building. Riki realizes that he has seen Ken before, but misses his guess. Shun and Riki don't seem to recognize the male student on the teacher's side. When Kaidou asks for a handshake from Haganeno, he is stopped by Ken's female student - Hinoki Nozomi, who plays the role of his manager. She introduces her classmate - Masayuki, who "guillotines".

Ken then introduces himself to Kusuo's class as their teacher, as he's there to give them a special lesson. Students chatter around, recognizing the teacher, as Nozomi approaches PK's principal to discuss the fee for Ken's class. Ken starts off the lesson by insulting everyone in the class and calling them names. He explains they all lack the three principles of a real hero - courage, kindness, and strength. He points at Shun, Riki, and Aren and judges them based on previously mentioned principles they supposedly are missing, but Ken's judgment is the complete opposite of the truth. Ken states he will become the main character of this manga and turn Kusuo, his class, and his new classmates into heroes. The transfer students are Nozomi and Masayuki in this scenario. Kusuo realizes Ken plans to hijack the manga.

Ken starts his first lesson with a quiz, but when looking for a student to challenge he punches Takahashi, simply for having an annoying face. Kusuo gets called to the front and asked a question about a girl being attacked by a monster and what Kusuo's choice is to do in this scenario, to which he simply leaves the classroom. When Ken walks out the door after Kusuo, he gets transported into a fantasy world. Kusuo recreates the scenario from Ken's quiz and put Nozomi in a cave with a monster about to attack her, but as Ken runs to her, he leaves her a sword and runs off. It's a wrong answer - Kusuo tells him to stay in this new, perfect world for him, world and vanishes. Ken's fate after it is unknown.

In a bonus frame, under Asou's note, four more Our Hero Studies characters make an appearance. Ishio and Jun get a speaking role in it, while Jou and an unnamed background character do not.
