Yamamura (Kenta Kawasaki) is enthusiastically explaining his favorite anime to Tamura (Yoshiyuki Yamaguchi), while Himuro (Yasukaze Motomiya) reads a novel—creating a warm and peaceful mood in the office. Just then, Ishizawa (Hiroto Honda) arrives, carrying Himuro’s guns. Himuro takes out two pistols to clean. One is a magnum gifted by Tamura. And the other… is the very gun tied to a fateful incident between him and Tamura.
