Oumatsu

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

Danganronpa V3/Main Story
Kaede meets Kokichi for the first time in the prologue, when he is teasing Keebo; When Kokichi mentions in a childish tone that Keebo is a robot, Kaede is surprised and asks him if it is true. Her first impression of Kokichi is that of a "mischievous little kid who is bothering one of his classmates". After Kokichi introduced himself as the Ultimate Supreme Leader, she was intrigued and began asking him about his unusual talent, saying that she didn't understand it well and asked Kokichi to explain it. He then said that he was "just" the leader of a secret organization containing more than 10,000 members, and she was very impressed at first, but after Kokichi was revealed to be a liar, she started accusing him of lying about almost everything he says. When she asks him if he was lying or not about his organization, he replies "Nishishi... I'm not telling youuuuu!".

For Kaede, she did find Kokichi a little mysterious because of his carefree and mischievous personality, sometimes wondering what he was planning, and although he can be difficult, really wanted to get along with him. In Kokichi's introduction, both in the demo and in the game itself, Kaede clearly recognizes on to a certain level that some of his annoying attitude is just his way of teasing others, and that he doesn't seem particularly malicious or evil. More specifically, she describes him as "having a childish side that makes him hard to hate". Kaede is one of the only people who was kind to Kokichi and deeply cared about him, and she was also one of the only people Kokichi never hurted in any way, due to her early death in the story. For Kokichi, Kaede appeared to be one of the students he was more interested in, as he appeared to have fun while talking with her and sometimes was seen becoming more serious and enigmatic while they were talking alone, which seemed to indicate that he had some form of respect for her. He seems to enjoy her company and also likes to tease her mischievously as he loves to do with everyone.

Throughout the game, most of the interactions between Kaede and Kokichi contain a moment where Kokichi tries to help Kaede by offering her a lot of perceptions she hasn't thought of, like opening her eyes to things because he cares about her and wants to protect her from the killing game because he knows that with this way of thinking, she is vulnerable. For example when he questions Kaede's common sense in their FTE, or when he points out that not everyone thinks like her when Kaede pushes the group to finish the Death Road of Despair. He also once questioned Kaede and Shuichi's relationship to be so "close", and said that he personally felt more anxious around people who share everything with each other than with strangers. Considering that earlier in the conversation Kokichi told Kaede that for now they were just strangers, this seems to indicate that he felt somehow safe around the pianist. When Kokichi becomes more serious trying to explain things to Kaede, she seems to think about it after the conversation but doesn't say anything, realizing that he maybe was right.

During the trial, Kokichi was the first to discern Kaede's lies, and brought them up to advance the debate. He also tried to prove to Kaede that Shuichi was the culprit, but Kaede managed to refute his argument. Kokichi then tried to come up with a counter-argument, but failed and admitted that he was wrong. He apologized to Kaede and said "Uhh... Guess you're right. Sorry, I didn't think that far ahead". When Shuichi accuses Kaede of being Rantaro Amami's killer, Kokichi has a very different reaction than his usual temper. He seems sad and even tries to defend Kaede, saying that it's "pretty unfortunate" with an angry tone, and that he can't believe it's Kaede, because that she kept pushing them forward and urging them to cooperate, so it seems strange that she would kill in cold blood. After Shuichi explained why she didn't killed in "cold blood", Kokichi remained silent and spoke little during the rest of the trial. After Kaede is found guilty for the murder of Rantaro, Kokichi explains her why she fell right into Monokuma's trap, and that even if it was to protect everyone, she started the killing game the second she "let the murder fill her heart". After Tsumugi and Gonta accuse him of being too hard on Kaede and that he shouldn't talk to her like that, Kokichi says that he feels guilty for not having been able to do anything to prevent Kaede from killing Rantaro, calling himself useless, but many of his last words were taken as lies by some of his classmates. Even though he knows that what Kaede did was bad, he still seems grateful to her for saving them from the time limit, saying that if she had not done anything, everyone would have died.

After Monokuma announces that Kaede is going to be executed, Kokichi looks at Kaede with a neutral and serious look and says that she "definitely wasn't boring". It is important to note that this is a notable and rare compliment from Kokichi, and that he said this to only a few people. Not to be boring is a fundamental value for him, and he doesn't think that about everyone. Also, the way he looked at Kaede often seemed to express the truth and authenticity of his words in him. In the Japanese version, Kokichi says '赤松ちゃん、じゃあね. キミはつまらなくはなかったよ. ' "See you later/next time, Akamatsu-chan. You were not boring." His last words to Kaito before he died were similar as the ones he said to Kaede before her execution: "At least I wasn't boring... right?"

After her punishment, he cries and say "I... I can't believe this happened to Kaede... I liked her s-so... m-muuuuch... WAAAAH, KAEDEEEEEEE!!!!" But this is quite different in the Japanese version since he says 'う、嘘だ・・・オ、オレの・・・大好きな赤松ちゃんが・・・!' "Ugh... Is that a lie...? My... My beloved Akamatsu-chan...!" the kanjis used for a passage of this sentences are '大好きな' Daisukina Akamatsu-chan (daisukina is used to describe a strong love for someone), and '大好きな赤松ちゃん' "My beloved/favorite Akamatsu-chan". Daisuki(na) is a Japanese word that can be interpreted both as a platonic or romantic way.

Even if it is not explicitly shown because of Kokichi and his constant habit of lying, Kaede's death has affected him a lot. It seems that Kokichi shut down soon after Chapter 1. Even though during Chapter 1 he seemed to express himself honestly with Kaede and the others and then cover it up by pretending it was a lie, from Chapter 2 on, he didn't seem to open anymore at all. If during Chapter 1 he was not really trying to prevent the murders, only after Chapter 1 and Kaede's death, Kokichi immediatly tried to find a way to end the killing game; In Chapter 2, he made sure that the killing game did not resume by manipulating Gonta, and stealing all the student's motive videos. In Chapter 4, he used Gonta and Miu to make everyone die without knowing the truth of the outside world, thus stopping the killing game, but failed. In Chapter 5, he sacrified himself like Kaede for the same reason she did - to stop the killing game, having pronounced similar phrases as Kaede's before her execution, as if Kokichi still remembered those words even in Chapter 5. For example, Kaede said "End this ridiculous killing game, survive and get the hell out of this place" before her execution, and Kokichi said "The reason why I pretended to be the mastermind... Was to end this boring killing game" before his death. Kaede also said "I definitely won't let that happen, even if it costs me my life" during her trial, and Kokichi said to Kaito "There are no depths i won't sink to... Even if I have to sacrifice myself". Kokichi continues to talk about Kaede from time to time, such as when he is the first to mention her in Chapter 2, asking Shuichi if he took off his hat because of "the effect of Kaede's death". In Chapter 3, if the player chooses to talk to Kokichi after the meeting with Angie about the Necronomicon, Kokichi will tell Shuichi that he doesn't really want Rantaro to be the one to come back to life, and that he would have preferred Kaede to resurrect. Kokichi is usually known for choosing logic over emotions, and even after everyone thought that the most logical choice was to resurrect Rantaro, Kokichi still wanted Kaede to come back. Kokichi also mentioned to Kaito during his last words that he had to kill him, so he and Kokichi could ruin the killing game as tribute to "those who died" and that way "they could finally rest in peace". This is a parallel to Kaede and Kokichi's first Free Time Event, in which Kokichi asks Kaede if she came to him to offer her life as a tribute for him. In Japanese, he says "We have to end this killing game. That way, even the dead can be remembered."

The main theme of Danganronpa V3 is "Truth vs. Lies". Kaede and Kokichi are both the representatives of this concept like two sides of the same coin. Both openly represent a concept to other students, but they also represent each other's concept in some way: Kaede represents the truth, trying to reach the truth of the mastermind and protect everyone all the time, teaching Shuichi how to face the truth. Kokichi represents the lies, always lying to hide his true feelings and intentions. Kaede, on the other hand, never lies about her feelings, but she may try to lie in the case of reach the truth, representing her concept of truth quite "badly". Kokichi represents his concept badly too, because even if he says every time that he lies, we know by his last words that he only lied about lying, that he lied to himself, and the truth is he didn't like the killing game at all, while his entire character was based on the way he enjoyed the killing game - which means that every word he said during the game can be interpreted as a lie or as the truth, because that's how you hide a truth: by pretending it's a lie. A big difference between them is also their trust, since Kokichi never trusts anyone during all the killing game, while Kaede's main values are to believe in everyone. That's highly possible that Kokichi was trying to trust Kaede as the leader of the group and someone that everyone could trust (which is why he seemed to respect her a lot), but lost that trust after realizing that Kaede died trying to openly help everyone, using her in the 4th trial as an example of how "trusted people" can still kill, by saying "信じた" ("believed in") A closer translation of this phrase would be "the person we believed in". After Chapter 1, Kokichi then started to trust Shuichi Saihara, the closest person to Kaede, and began to search for a way to stop the killing game without others suspecting it, not to repeat "Kaede's screwup" according to him. The Lies VS. Truth theme goes even to their deaths which are both more or less lies from the group's perception; Kokichi tried to pretend his dead body was Kaito Momota's, but everyone discovered the truth and Kokichi's secret plan. While the group thought Kaede's plan to kill the mastermind in Chapter 1 had worked, they later realize during the 6th trial that the truth they had found was in fact a lie, and that the real culprit was Tsumugi Shirogane.

In the non-canon trial of the game demo, Kokichi makes Hajime be quiet so that Kaede can continue her explanations. He then tells Hajime that if Kaede was the only one talking, they should be done with the trial soon.

In Kaede and Kokichi's respective relationships charts, Kokichi comments "念だったね!"  'What a shame!'  for Kaede, possibly referring to her early death in Chapter 1, but it might be more possible that he refers to Kaede's refusal to become a member of his organization. Kaede comments "力し合おうよ!"  'Let's help each other!'  or  'We should cooperate!' about Kokichi, proving that even if she sometimes finds him annoying, she still wants to work with him, trust and believe in him even is he's a liar.

Danganronpa V3/Free Time Events
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. Kaede will think "Is Kokichi going to be okay? Maybe I should stay by his side..." in the english version, to which Kokichi asks her if she if she came to him to offer her life as tribute for him but then tells her not to worry, that it would be boring to kill her now so he won't do anything of the sort. 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 turn down an invitation from her After that, Kaede sighs thinking it's a lie, and Kokichi tells her that if he's mean to her, it's Kaede's fault, because she forgot about him. He claims that they met before the killing game, and blames Kaede for forgetting their first meeting, while he tells her that he has never forgotten her and that he has been thinking about her this whole time. In one of the 3 options of response, Kaede says "W-wait a minute! I don't remember ever meeting you!" to which Kokichi replies "So you did forget! You completely wiped me out of your memories! How could you be so heartles...?" and Kaede will think "Is Kokichi genuinely sad? Have I really forgotten about him?!" the last choice is "Are you thinking of someone else?" and Kokichi replies "There's no way i'd mistake the Ultimate Pianist for anyone else!" for what Kaede replies "I guess that's true..." Kaede then blames herself and apologize to Kokichi, asking him to refresh her memory so that she can remember him. Kokichi replies that they met while he was run away from his enemies; Kaede secretly protected/sheltered him and raised enough money to finance his escape using her talents as the Ultimate Pianist. He will add to this that he ended up betraying her and sold her to his enemies, and that she was swiftly killed after that. Kaede understands that this is a lie from Kokichi and he confirms that the only place they met is at the Academy for Gifted Juveniles and say ''"Akamatsu-chan is a good-natured person to be deceived by such a lie~!" (Japanese Version)''. After questioning Kaede's common sense, he then apologizes.

Even though Kokichi made Kaede understand that his statements were lies, there are a few things that leaves us suspecting that he was not lying, because in the second choice option, when Kaede asked him if he was lying about the fact that he was thinking of her and that they met before the killing game, Kokichi looked her in the eyes in a serious tone (which often seems to prove the truth in him) and told her "... No. I wish I was... but even I'm not that good at lying. Ahaha... I may be a Supreme Leader, but my lies have standards." Even Kaede, who knows Kokichi is a liar and suspects him a lot of lying with every word he says, commented internally about how he seemed really serious about it. If we consider that he didn't lie, then it means that the two may have known each other before the killing game, so as pre-game Kaede and Kokichi, but it's also possible that he remembers Kaede because of the falsified memories created by Team Danganronpa.

During their second Free Time Event, Kokichi warns Kaede that it is dangerous to wander alone, and then pretends that Keebo is behind her with a knife for Kaede to stays with him so that she is not in danger anymore. He then accuses her 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. When she tells she don't know about that, he says "Don't worry! Akamatsu-chan definitely can do it! You'll be hyped up all over the world!" He then tells her "Join my organization, and together we'll do as we please to all the stupid plebs in this world. Let's sit on top of the world and look down on everyone else... And if we wanna watch the world burn? That's fine, too! We'll light the whole thing up! The Ultimate Supreme Leader and the Ultimate Pianist joining forces sounds pretty sweet, huh?" 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 cuz I actually 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 ends with an unaffected Kokichi. We find out later with his Motive Video that he considers his organization as his close friends and family, and that they are the most important people in his life, meaning that Kokichi asked Kaede to be part of the most important people in his life.

Kokichi will only initiate 2 FTEs in Chapter 1, with Kaede. After Kokichi has completed 2 FTEs, he will still accept gifts, but will not initiate any further Free Time Events. However, there are a few introductory sentences for the player to do the Free Time without the event. One of these is Kokichi who wonders why the school building has barred windows, and wonders if it's so they can't escape, but since they can enter the courtyard, maybe it's actually just for decoration. When Kaede proposes him to spend time together, Kokichi replies "No thanks! ... Just kidding." Kaede will then spend the rest of her Free Time being tricked by Kokichi's lies, without however leaving. The second is Kokichi being worried about the time limit imposed by Monokuma, because they will all die. He then wonders what Monokuma is going to do; End this killing game, or start a new one? When Kaede asks him if he wants to spend time with her, he tells her not to worry, implying they will have a lot of time because he's not going to die anytime soon, half-jokingly. Unfortunately, they didn't have that much time, because of Kaede's death in Chapter 1.

Danganronpa V3 Manga/Anthology Comic
In Danganronpa V3: Anthology Comic Vol. 1, Kaede wants to help Kokichi see Keebo's "human" side so that they can finally get along. Kaede dresses Keebo in a Kimono, but Kokichi points out to Keebo that his school uniform screams robot, and that it's weird to dress a kimono over it. Kaede finally fails to change Kokichi's mind. Later in the manga, Kokichi had made a joke about Gonta becoming the first victim of the killing game, so Kaede and Kokichi go together to Gonta's dormitory with Kaito, Angie and Shuichi to see if Gonta is okay. When the Monokubs arrived a little later, Kaede asked Monokid why he's harassing Monodam so much, to which Monokid replied that he's keeping himself healthy and that it's to externalize the stress. Kokichi then said "I totally get it! Beating up on inorganic objects like robots really clears the head!", referring to his habit of harrassing Keebo, showing once again that Kaede failed to change his mind. After Kokichi told Gonta that the insect he found was a beetle drone, Gonta started a monologue about why calling it a drone beetle was wrong. Kaede listened to Gonta talk and seemed interested, but Kokichi fell asleep behind Kaede following Gonta's monologue.

Later, Kaede tries to comfort Himiko by asking Shuichi to "solve the case" because Himiko had a dream about Kokichi harassing her, so Kaede and the others go to talk to Kokichi about it. Kaede then tells Himiko that she shouldn't pay attention to Kokichi's torment. A little later, Tenko hits Shuichi with Himiko in his arms, leaving Kokichi and Kaede alone apart from the group. The two look at each other and Kokichi asks Kaede if her plan worked, to which she replies "I guess?".

In another story in the same chapter, Kaede opens a conference to take stock of all the victims of Kokichi's pranks. After hearing the testimonies, Kaede launches "Operation Catch Kokichi" "Starting operation Catch Ouma-kun!", and says that she will do her best to catch Kokichi. Kaede then goes to talk to some students to help her in her mission and after getting ready, Kaede spots Kokichi and tries to chase him until she comes across Maki strangling Kokichi. So Kaede tied Kokichi with a rope and Kokichi says ''"C'mon guys, I was just playing heel to increase the group's unity~ Isn't tying me up a little too cruel?" "Well it's a lie, anyways!"'' and Kaede makes a comment about how it still made everyone cooperate to catch Kokichi. Kokichi then raises his hands sharply, which unties him from the rope while saying "Got ya!". Kaede throws herself on the rope, but Kokichi manages to escape. The chapter ends with Kaede on the floor, saying "Geez! Seriously. We never know what Ouma-kun's thinking...".

In Danganronpa V3: Anthology Comic Vol. 3, Chapter 3, when Kaede is looking for a way to avoid a potential murder, Kokichi tells her that they could just fly up on Keebo's back, which gives Kaede an idea. Kaede asks Keebo if he has his own feelings even though he's a robot, and after Kaede being called robophobic by Keebo, Kokichi says "I got it, Akamatsu-chan is fed up with how much of a sucker Ki-boy is, just like I am!", to which Kaede replies "that's not it!". Kaede then tells everyone about her plan and they all agree to educate the Monokubs to stop the killing game. Kokichi is in charge of making Monotaro think he's his brother. Kokichi does pretty well at first, and Kaito points this out but then Kaede says "Ah, but that's bad! Look at Ouma-kun's face, he seems to be having a hard time resisting the urges to say "It's a liiie~"" in the end, Kaito and Shuichi put themselves in front of Kokichi to avoid him to speak, and Kaede's plan is a success. The next day, the Monokubs killed each other and Kaede says that it was different from what she had imagined, to which Kokichi replies "Told ya robots were useless!".

Later in another chapter, Kaede, Rantaro and Tsumugi are discussing what Rantaro's talent could be, when Kokichi interferes in the conversation and asks if they are talking about something interesting. Kaede asks Kokichi if he wants to know Rantaro's talent too, and he replies "Well, duh!". At the end of the story, Kaede tells Rantaro "We should all cooperate with each other from now on!" to which Kokichi replies that he will continue to doubt everyone to tease Kaede, and she yells at him "Seriously, Ouma-kun?!" to which he replies "Aw, don't be like that! Nishishi~".

Bonus Modes
Whether in Danganronpa S: Ultimate Summer Camp, Danganronpa V3: Ultimate Talent Development Plan or even in Salmon Team, Kokichi and Kaede don't have any interactions/events together, mainly due to Kaede not being the protagonist anymore. Salmon Team being focused on Shuichi's FTE with the others, it is impossible to play as Kaede and thus to have access to the rest of her Free Time Events with Kokichi, or to the non-canon events Salmon Team Graduation Event, Love Hotel and Harmonious Heart. In UTDP, Kokichi and Kaede have no events together either, but were classmates who studied at Hope's Peak Academy together for three years.

However, in one of Kokichi's Death Cards in Danganronpa: Talent Plan is written the sentence "Well... You definitely weren't boring." as his signature phrase, that being his last words to Kaede. It is written on his third and final Death Card, which is supposed to be the student's most important card, with a line written on it they said during the game that they hold dear. For exemple, Korekiyo talks about his lover/sister, Kaede talks about the impact of her final wish, Himiko talks about the impact of Tenko's death, etc. So it seems like Kokichi's dearest line through the whole game was the last words he said to Kaede. His first card also contained the sentence he used to introduce himself to Kaede.

In Danganronpa S: Ultimate Summer Camp 's Hifumi Yamada Events, Hifumi comes to see Kaede to talk with her about a fanfiction idea he had. He plans to write a romance (少女漫画 Shōjo in Japanese) between a pianist and an evil leader ("leader of evil forces"). The romance is between a pianist who fight evil forces at school with her band, but has a secret crush on the leader she fights, her feelings being reciprocated on the leader's side since it is a romance. When Kaede hears Hifumi's story, she tells him that she relates to this pianist and that the "character resonates with her so much", saying in japanese that the character is "the same as her". After that, Kaede helped Hifumi writing the romance. It should be noted that Hifumi takes inspiration from the real traits of his classmates or other students to write his fanfictions and his characters, as seen especially in his interaction with Shuichi and Kyoko, so the fact that Hifumi came to see Kaede proves that he obviously refers to her in his romance. It may seems too that Kaede might actually have a crush on some evil leader, and Hifumi seems to see a potential relationship between this certain leader and Kaede. Nowhere is it mentioned that the Evil Leader in the romance refers to Kokichi, but with Kaede representing the Pianist, the only person who can represent the Leader is him, with his talent being the Ultimate Supreme Leader since he is the only person whose talent is so close to the character, often referring to himself as "leader of evil". Also, the main plot of the romance, "the pianist fights the evil leader with her band" is a direct reference to the main game, in which Kokichi was introduced as the main antagonist, and Kaede as the protagonist. Even if initially in Danganronpa V3 Kaede did not seem to show such feelings towards Kokichi, the fact that Hifumi was inspired by Kaede to create a character canonically in love with the leader she fights to write romance with the plot of the main game should indicate that Kaede seemed to have, somehow, feelings towards him (at least in Danganronpa S).

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 next protagonist of the game, the ship appealed the 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, referring to her as "My beloved Akamatsu-chan", and offered her to rule 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. Some fans also became interested in Oumatsu after realizing that both of them died for the same reasons, "to put an end to the killing game", Kokichi being obsessed with "ruining the killing game" for the sake of their "classmates who died", and that it is it is strongly implied by many elements that Kokichi tried to honor Kaede's last wish after her execution, seeing her as a kind of example for him. Some fans of the ship think that Kokichi has a crush on Kaede, because he only started to be interested in her best friend after her death. In the end, both gave their lives to stop the killing game, but both failed.

While it's not the most popular combination for the two, it remains among the most popular shipping choices for both characters included. The relationship between Kaede and Kokichi not being shown explicitly, the ship is overshadowed by more popular ships such as 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.

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. Fans may often headcanon Kaede as a "therapist friend" for Kokichi, because of her nature of taking care of everyone, and thinks that their relation could improve if Kaede didn't die in Chapter 1, leaving many fans thinking that Kaede would have made a better protagonist than Shuichi. Some fans prefers the ship in a platonic way, Kaede being like a big sister to Kokichi, but most of the shippers prefers Oumatsu in a romantic way. Some fans of the ship seem to prefer the pair with pregame Kaede and Kokichi, even though we don't know their relationship before the killing game. Oumatsu is often considered a "steal your girlfriend/boyfriend" meme, because Saimatsu and Saiouma are much more popular than Oumatsu, the fandom sees Kokichi and Kaede as Shuichi's main "crushes". Another popular meme between the two is also Kokichi's line "But that's Kaede's lie, isn't it?" in the first Scrum Debate.

Trivia

 * This is the third Danganronpa ship between the protagonist's implied love interest and rival, with the first two being Togiri and Komanami.
 * Just like Komanami's case, the love interest dies executed, and the rival murdered. Furthermore, the rival (Nagito/Kokichi) dies as a victim in Chapter 5, and the love interest (Chiaki/Kaede) becomes the blackened not knowing who she had murdered in the first place.
 * Because of a lack of interactions between Kokichi and Shuichi Saihara in Chapter 1, it's possible that after Kaede's death, Kokichi switched to Shuichi and started to be interested in him because he was the closest person to Kaede, Shuichi becoming a sort of incarnation of Kaede's final wish after the first trial (especially since Kokichi would refer to both as "his favorites" and told them both approximately the same things.) One of Kaede's other wishes was also for everyone to be friends, and Kokichi immediately sought to get closer to someone (Shuichi, the closest person to Kaede, and seemed to be friend with Gonta.) after Chapter 1.
 * Kokichi will also refer to Kaede before the scene of his confession in chapter 4 by telling Shuichi "And you wanna save everyone... riiiight?". After Shuichi leaves the Neo World Program, Kokichi says he would do anything to get "someone he likes" to notice him, even strangling them. He could have made a joke about Miu Iruma's death that happened right after, but it's a bit ironic for Kokichi to say that when Kaede died by being strangled (especially when he's alone, so there's no one to told this joke.)
 * Like the other culprits, Kokichi recovered Kaede's camera used for the murder of Rantaro Amami and kept it in his dormitory. He also has a picture of Kaede on the board in his room. It is highly possible that he thought of keeping the objects of the murders and organizing his chart after Kaede's death, since she was behind the first murder.
 * Danganronpa creator, Kazutaka Kodaka, liked the tweet of a cosplayer duo cosplaying as Kaede and Kokichi for Kaede's birthday.
