Return to Ishiyama High School Arc
Following the revival of Ishiyama High School, Akahoshi and his crew returned back for the new year. He encounters a group of delinquents near the entrance who ask Akahoshi about the school he is from; he responds that everyone present is from Ishiyama. Several others begin arriving at the school with an apparent goal of taking down Tatsumi Oga for the status as top of the school.

Later, while standing around outside Ishiyama's campus, several of Akahoshi's fellow delinquents discuss the return and mayhem caused by Shintarō Natsume and Hajime Kanzaki. One of them, Haizawa, declares that they should take action and says for Akahoshi to come along. Akahoshi simply turns around to look at the third-year student.

Akahoshi and his crew head inside the buildings towards Oga's location, where they find that he is stuck in the ceiling, thanks to Yōhei Nasu. One of the other individuals present is Ebian Ichikawa who remarks on Nasu's actions. Akahoshi, who hears what Ichikawa is saying, redirects the latter's words back to him. After that, he properly identifies his former high school and threatens to burn its name onto anyone who would forget about it. Following this, an uproar is held in the hallways of the building, until Oga speaks out from the ceiling. Following this, Akahoshi takes a long silence and simply watches the following events take action.

However, after Ichikawa makes the first move against Nasu, this drives Akahoshi to also take action. He lunges in to punch Ichikawa though he ends up smacking the latter's sheathed sword instead; this is because Ichikawa already noticed that he has been making his move. Furthermore, after being "fully awakened" from Ichikawa's previous attack, Nasu grabs hold of both delinquents and flips them both on the ground; however, Akahoshi breaks free and saves himself from being injured, and he angrily adds to Nasu that he shouldn't rip a technique from a video game series. While standing on the ground, Akahoshi then witnesses Oga demolish a large portion of the school with one strike, leaving him impressed and awed by the feat.

This feeling is eventually replaced with confusion when Nasu unexpectedly leaves the vicinity while adding that he will take away Oga's child. Akahoshi wonders about it as he watches a comical scene between Oga and Baby Beel. Then, when Ichikawa leaves with an unfriendly remark, Akahoshi simply watches him go with an angry and serious expression. He then goes over to Oga to explain more about Ichikawa; moreover, he provides a few personal comments about him. Akahoshi then addresses his name and his ambitions to Oga, proclaiming that someday, using his own power alone, he will defeat Oga and be the one reigning Ishiyama. The following day, sometime in the morning, Akahoshi and Shigemori head to the male restrooms where the former washes his hands. Akahoshi listens to Shigemori bring up Oga and Nasu's fight; instead of feeling worried, he is calm about the situation, even explaining to his subordinate that he is confident about Oga's capabilities. Moreover, Akahoshi adds that after having watched Oga fight before, he is sure that he will the one to defeat Ishiyama's top dog. As Akahoshi then opens the door, an unexpectedly-childish Oga runs through the hallways, leaving Akahoshi and Shigemori confused.

Later, Akahoshi is seen walking near a barbed fence with another person.
