Oumatsu

Oumatsu is the het ship between Kaede Akamatsu and Kokichi Oma from the Danganronpa fandom.

Canon
Their first Free Time Event starts with Kokichi saying he doesn't want to die and that Kaede can stay by his side for a while. The rest of the Free Time Event is spent by Kaede trying to prevent Kokichi from trying to do anything 'stupid'. At the end, Kokichi asks why Kaede approached him in the first place, to which Kaede replies that she just wanted to do so, and was fine if Kokichi didn't want to spend his free time with her. He then says, he'd never turned down an invitation from her, but then adds that it was a lie. After lying about their first encounter, he then apologizes.

In their second Freetime Event, Kokichi accuses Kaede of wanting to kill him, after which, if the player chooses to spend time with Kokichi, Kaede will have to chase after him, which amuses him. Afterwards, Kokichi asks Kaede for a favour, which is Kaede working for him as an agent in his secret organization, as he believes Kaede will go on to 'represent Japan as a pianist' and thus she could go abroad without any suspicion, and meet as many powerful figures as she likes. He then tells her "Join my organization, and together we'll do as we please to all the stupid plebs to the world. Let's sit on top of the world and look down on everyone else... And if we want to watch the world burn? We'll light the whole thing up!" In response, Kaede questions the existence of his secret organization, to which he retells Kaede that he is a liar. At the end of the event, Kokichi says "But y'know I'm only saying this because I care about you, right Kaede?' You can keep thinking like that, but don't come back crying to me when things don't go your way." Kaede then refuses to be an agent of his secret organization, which it ends with an unaffected Kokichi.

After Kaede is found guilty for the murder of Rantaro Amami, Kokichi says that Kaede definitely wasn't boring.

Fanon
The ship sailed with Kaede being the first protagonist of Danganronpa V3 and Kokichi coming off as a "rival character", being a compulsive liar, thus representing one side of the "Truth vs. Lies" theme. Even after the reveal of Shuichi Saihara being the actual main protagonist of the game, the ship appealed tho fans of the ships between the main character's support characters and rivals. The ship was fueled even more because of how Kokichi said that he cared about Kaede and offered her ruling the world by his side. What makes this ship even more popular is that Kokichi told Kaede to join D.I.C.E, who are the most important people in his life, meaning he told her to be one of the most important people in his life.

Oumatsu is rivaled by both Kaede and Kokichi's respective ships with Shuichi, Saimatsu and Saiouma. Though, a poly ship between all three of them has been created as well. Oumatsu is also rivaled by other ships such as Oumota and Irumatsu. While it's not the most popular combination for the two, it remains among the most popular shipping choices for both characters included.

Fan fictions and fanarts may often pick up a scenario where Kaede agrees to Kokichi's offer to rule the world with her, becoming a member of D.I.C.E alongside him as a result.
