Return to Ishiyama High School Arc
Word reaches out to the Sabatō delinquents that Yōhei Nasu has already confronted Tatsumi Oga; upon hearing the news, Kajiura curses at the "Beast", due to the fact that he now has a higher chance of reigning at the top of Ishiyama. Kajiura asks Ichikawa about what they should do next, in light of the situation. The Sabatō delinquents eventually decide to confront Nasu and perhaps Oga as well; soon, they arrive at the hallways where the two are currently located.

Kajiura then stands aside while Ichikawa eventually makes his move towards Nasu. He grows concerned when Ichikawa is seemingly injured by Nasu, causing him to shout out Ichikawa's name with concern; thankfully, he is not at all hurt. The confrontation soon comes to a closure after Nasu leaves with his fellow Poltergeists, leaving the other delinquents behind in the hallways. Ichikawa decides to leave afterward. As a result, Kajiura leaves with him and the others.
