Ep. 5: Ōba melakukan restrukturisasi Kifūken sementara Umeda menjadi terobsesi dengan Himeko, seorang mata-mata shokujinki.

5

Ōba exposes his plan to reformulate the Kifūken's organization with the help of Kazuma; who agrees believing with his help he can mold the Kifūken the way he likes. As for Kazuma, he makes his three friends Knife Tsutsuji, Shin Hoozuki, and Souichi Umeda executives. But Umeda's mind goes elsewhere when he becomes fixated on a girl named Himeko who works at an image club. Meanwhile, Kazuma eagerly hopes that he can change the Kifūken and tries to get Rie's attentions, romantically. Though she admits she likes him, it is clear that she is fixated on Toshihiko. The next day, it is revealed that Himeko's real name is Suitsuki Misao and is a shokujinki. Umeda comes to her aid when the Kifūken attempt to kill her; despite their pleas that she is a shokujinki spy. Back at the dojo, Rie discovers journals in a hidden room in Jūzō's old room, while she's looking for finical reports. Much to her shock, she discovers a secret that both Jūzō and Toshihiko kept from Kazuma. Downstairs, Ōba pushes Kazuma to eat octopus (something that is hinted to trigger shokujinki nature more, along with alcohol). Despite the Kifūken's best efforts, Umeda escapes with Himeko, but, at the end, she devours him and escapes. (Source: Wikipedia)
