Ayabe Arc Edit

Hayasaka is mostly unseen throughout this arc, but later appears in Chapter 66, helping Tomohiro Kawauchi in stopping Kyoutaro Okegawa from attending the makeup of the makeup test. It is revealed that the one who assisted Hayasaka during the club audit was Kawauchi, as he had written and taken photos for the Public Morals Club.

He spends the rest of the day setting up traps in Midorigaoka's forest, though they are mainly for his own amusement, consisting of dominoes, toast, novelty items, and bowling pins. The traps are mainly ineffective, but appear again when Goto switches sides to Kawauchi's team.
