Oumami

Oumami is the slash ship between Rantarou Amami and Kokichi Ouma from the Danganronpa fandom.

Canon
Like everyone else, Rantaro can be a bit annoyed with Kokichi's behavior. While the two are not shown interacting much, Kokichi called him "My dearest Rantaro" ("My beloved Amami-chan" in the original Japanese) and cried when he saw his corpse. However, his attitude changed very quickly, making it hard to tell which one of his reactions was truthful. Kokichi later claims he doesn't want Rantaro to come back to life, because he'd rather have Shuichi's wish to have Kaede come back true, to make Shuichi happy.

Much later, it's seen that Kokichi has the life-like statue of Rantaro made by Angie hanging upside down next to his bed, as a part of the evidence pieces he has hoarded. He chose it over Kaede, Kirumi, and Ryoma's, indicating that he has more interest in Rantaro than them.

Fanon
One of the reasons that made some fans ship Rantaro and Kokichi is the latter having Angie's wax figure of Rantaro in his room.

Another reason came from an official art (the page's info-box picture) showing the two together in a rather suggestive pose.
