Saioumatsu

Saioumatsu is the poly ship between Shuichi Saihara, Kokichi Oma and Kaede Akamatsu from the Danganronpa fandom.

Canon
You first meet the two male characters whilst playing as Kaede. Shuichi was the first to wake up with our protagonist, thus immediately becoming the token deuteragonist supporting her. After Kaede snapped Shuichi out of his state of panic, the two had a brief discussion on where they could be after waking up in the classroom, introducing themselves to each other as "ordinary students" before they're interrupted by an Exisal breaking into their classroom and chasing them to the gym, where Shuichi leads Kaede to.

After the duo get their memories, they're transported back to the same classroom and are forced to re-do their introduction sequence, this time introducing themselves to each other as the Ultimate Pianist and the Ultimate Detective for Kaede and Shuichi respectively. The two follow each other and meet all of the other characters together, one of said character's being Kokichi Oma, who immediately sparks both Shuichi and Kaede's interests due to his mischievous and eccentric behaviour after introducing himself to the two as the Ultimate Supreme Leader, one of which who runs an evil secret organization with over 10,000 members, before immediately claiming himself to be a liar and that the whole "10,000 members" thing mightn't be true. Kaede and Shuichi question Kokichi on this matter, but he isn't very responsive.

Further into Chapter 1, Gonta announces he remembered he found a manhole in the boiler room behind the school and all 16 of the trapped students follow him. After he lifts the manhole cover off with ease, the group go down and discover the Death Road of Despair. Kaede, determined to escape the Killing School Semester before it starts, convinces everyone to try it. After several failed attempts, Kokichi gets angry at Kaede and blames her for the groups agony, as everyone around her, including Shuichi, are mentally and physically drained.

More into Chapter 1, Shuichi finds a hidden passageway in the library and informs Kaede about it. The two investigate it together and come up with the idea that maybe one of the students inside the academy with them is the Mastermind of the killing game, prompting Kaede to come up with a plan to kill said mastermind in order to help everyone escape. While waiting for their plan to come together, the two share a heartwarming moment as Kaede comforts Shuichi with her hand on his.

During Chapter 1's Class Trial, Kaede protects Shuichi and lies for him when he is accused of being the Blackened, the reason he wasn't defending himself being because he figured out Kaede is the killer and remained silent in order to protect her. Kaede notices this, and then urges the distraught Shuichi to convict her as the Blackened.

After Kaede is proven guilty for Rantaro's murder, Kokichi comments to Kaede that she "really was...not boring," and Shuichi attempts to grab her hand to save her as she is being dragged away by the token first execution neck-grabber.

For the rest of the game, you play as Shuichi, giving Shuichi and Kokichi their own separate moments.

Fanon
The ship sailed likely for the same purposes as Naegamigiri and Komahinanami did; Because their dynamic consists of the protagonist, his implied love interest, and the rival or because fans were stumped on whether to ship Saiouma or Saimatsu, but then remembered that Shuichi has two hands.

Trivia

 * The trio shares the "male protagonist, his implied love interest and his rival" dynamics with Naegamigiri and Komahinanami.
 * Like in Komahinanami's case, the love interest and the rival die, leaving the protagonist as the only survivor of the group. Furthermore, the rival dies as a victim in Chapter 5.
 * However, in this case, Kaede becomes the deuteragonist and dies.
 * Both of the names of the characters Shuichi is paired with start with the Letter "K"
 * This also sparks a joke in the fandom that Shuichi only falls in love with people whose names begin with K, as normally, the other person in his most popular ships names begin with "K." Such as Kaede, Kokichi, Kaito, and K1-B0.
 * Their Color Pallets Resemble the Bisexual Flag when Combined.

Variations

 * Saimatsu refers to the ship just between Shuichi and Kaede.
 * Saiouma refers to the ship just between Shuichi and Kokichi.
 * Oumatsu refers to the ship just between Kokichi and Kaede.
