Golden Future Cup
KOOGY's manga, Colorfusical, placed second in the Golden Future Cup. He tried to use his status as as a musician to get his fans to vote for his manga. This angers Fukuda Shinta, who leads Akito Takagi, Moritaka Mashiro, and Nakai on a complaint to the editors. KOOGY puts off working on his manga to have interviews, causing his manga to do poorly in the results.
Afterward, at the party of Mangaka, KOOGY seduces Aoki and performed his song for the other mangaka, announcing that he was going to be serialized in Jump SQ with Aoki on Colorfusical. The news reaches Nakai, who becomes driven to desperation and spends several weeks in the winter drawing Hideout Door outside Aoki's apartment.
