Chihaya believes that Tatsunosuke's actions are not enough to protect Igarashi, who may be the real culprit of the serial murders, and asks the president Tsukamoto Kazue (played by Matsushita Yuki) to serve as the guard commander.Because Tatsunosuke had caused a lot of commotion so far, Wzue agreed to Chihaya's request and no longer was under Igarashi's protection.
