Oumamimatsu

Oumamimatsu is the poly ship between Kokichi Oma, Kaede Akamatsu and Rantaro Amami from the Danganronpa fandom.

Canon
All of them are friends and students of The Ultimate Academy for Gifted Juveniles. They are also participants in the Danganronpa V3: Killing Harmony's Killing School Semester. Kaede and Rantaro are also the only ones whom Kokichi called “his beloveds” after their deaths. In the Chapter 3, Kokichi claims he doesn’t want Rantaro to resurrect, and would rather have Kaede back. However, he choose to keep Rantaro’s wax statue made by Angie Yonaga while he could’ve chosen Kaede’s. The death of the 3 are also all related to the mastermind: Rantaro tried to catch the mastermind, Kaede to kill them, and Kokichi to trap them. After Chapter 1 and Rantaro and Kaede’s back-to-back deaths, Kokichi started to try to stop the killing game.

In one of Kaede’s Free Time Events with Rantaro, Kaede tells him that she would love to get to know everyone more, and suggests they should talk more often. She also tells Rantaro that she plans to invite everyone to her next concert, thus including Kokichi.

Oumatsu
Kaede and Kokichi are very different, but also really similar. They have opposite ideals, but both of them had the same intentions with the killing game, and sacrificed themselves to save everyone. Kokichi, despite having a childish personality and likes to tease other people, is seen having a lot of respect for Kaede, and compliments her often. He supported her career as a pianist, and mentionned several times how he didn’t consider her boring, which is the highest praise he can give.

During their Free Time Events, if Kokichi is okay with the gift Kaede gives him, he will comment how she has ’pretty bad taste’, and says he thought they were of one heart and soul. In their first FTE, Kaede chose to spend her free time with Kokichi because she was worried he could ’do anything stupid’ when she saw he looked scared and sad. In the same FTE, Kokichi often flirts with Kaede, saying ’i’d never turn down an invitation from you, Kaede’ He also lies about their first meeting, telling Kaede that she wiped him out of her memories, while he has never forgotten her and was thinking about her all the time. In their second FTE, Kokichi asks Kaede for a favor, which is her joining his organization, DICE. Kaede thinks he’s just joking around, so she don’t really pay attention to his offer. The people from DICE are the most important people in Kokichi’s life, and he has asked only her and Shuichi to join his organization, but both refused. In the same FTE, Kokichi mentions that he’s trying to change her way of thinking because she’s vulnerable, and says that he’s just doing that because he ’cares about her’ or even ’is really thinking of her’ in the japanese version.

In the trial, Kokichi was trying to help Kaede to find the culprit of Rantaro’s murder, and appeared disappointed when he realized it was Kaede herself. Before her execution, Kokichi mentions that she weren’t boring, and, after her death, starts crying while saying ’Is that a lie... ? My beloved Akamatsu-chan!’, which is similar to his reaction when Rantaro died.

Oumami
While Rantaro can be annoyed by Kokichi’s behavior, he never said anything negative about him.

When witnessing Rantaro’s dead body, Kokichi called him “My Dearest Rantaro” or “My beloved Amami-chan” in the original Japanese version and started crying. Even if his tears were fake, Kokichi was still quite determined to figure out who the culprit is.

When entering Kokichi’s room, it’s seen that he has a statue of Rantaro in his dorm room that was made by Angie. While we never get a chance to ask Kokichi about it, it is hung upside down next to his bed. This suggests Kokichi would have spent a lot of time around the scuplture.

During one of the anthology comics, Rantaro seems to treat Kokichi like a little brother. When Kaede tried to catch Kokichi, they used Rantaro in order to use his ’Amami trap’ by standing in place to catch him with his arms and when Kokichi asks him to let him go, saying “Please let me go Rantarou nii chan!”, Rantaro softens and lets him go just for that moment. He treats Kokichi as a little brother in the other stories as well, being kind and patient towards him as if he were a small kid. It’s quite clear his experience as an older brother made him quite adept at handling Kokichi. Although he finds Kokichi a bit annoying and is probably someone he would never get used to.

Both are included in 3 Promotional arts of just the 2 of them, showing the two together in a rather suggestive pose.

In Danganronpa S: Ultimate Summer Camp, Kokichi asks Rantaro to join his organization, even if he himself said it was a joke before the event starts.

Amamatsu
During their Free Time Events, Kaede states that she wants to be friends with Rantaro no matter who he was in the past. Despite him having his talent as unknown and him being suspicious, Kaede still cares for Rantaro and respects him, and believes that he’s not the mastermind behind the killing game. Kaede lights his mind up with hope and made him not fall into despair. Rantaro seems to also care for Kaede, as he feels worried and commented on how she is trying to help everyone and said she should take it easy. He thinks Kaede is easy to talk to and feels ease whenever he is next to her. He calls both of them comrades amongst all of the Ultimates, since they’re a bit more ordinary than some others. Kaede tends to assume that Rantaro is a womanizer and attempting to hit on her, even though he always insists he’s not that kind of person. When she got invited by him to drink tea together, Kaede was curious and kept assuming if it was a dating sim where Rantaro could hit on girls. However, Rantaro admitted that his looks may resemble a playboy, but he is a chill, friendly guy. Later on, in Chapter 1, it was shown that Rantaro was painting Kaede’s nails and suggest a French slant nail design that Kaede needs since her nails were short.

When Kaede first discovered Rantaro’s corpse, her legs became to tremble and she was frightened to see Rantaro being dead. She demanded to figure out who would kill Rantaro and states how she will never forgive the person who would kill an important comrade. In the trial, Kaede believed that she was the culprit who murdered Rantaro and confesses her sins. She calls herself as a horrible murderer and is sorry for him and Shuichi Saihara directly the most and regrets for ’killing’ Rantaro after the trial end and later got executed.

In the non-canon Danganronpa V3 bonus mode, Kaede was waiting for Rantaro after the Christmas party almost ended. She was aware that Rantaro would come back soon. Kaede states how she left some cake for Rantaro. In the end, they ate the leftover cake together. As well during the sports festival Kaede stops by Rantaro’s soccer game and claims she’ll be cheering for him, Rantaro responds to this by being surprised.

Fanon
The ship sailed as a result of Kokichi's interest in the two who died in Chapter 1, and the fact that he suddenly wanted to end the killing game after their deaths. The fact he also called them both his beloveds helped. Their designs are rather nice together, in purple-green-pink tones. Their fanarts often shows the 3 doing a calm hobby like reading or walking together.

However, the ship is a rarepair in within the Danganronpa fandom. Rivals ships include Saiouma, Saimatsu or Amasai, and there is a more popular ship that includes Shuichi, Amasaioumatsu.
