Saiibo

Saiibo is the slash ship between K1-B0 and Shuichi Saihara from the Danganronpa fandom.

Danganronpa V3/Main Story
At first, Shuichi thought K1-B0 was one of Monokuma's relative which he declined, however. Shuichi was surprised how K1-B0 was a robot and also their classmate. In general, Shuichi appears to be nicer towards K1-B0 than most of the other students, but he still does occasionally say "robophobic" things that anger K1-B0. K1-B0 appeared especially offended and angered when he was kicked out of the seance and replaced with Shuichi. K1-B0 blames the detective and tells him that he won't forget this. However, Shuichi does sometimes encourage K1-B0 by telling him that he's fine the way he is, but he also feels a bit awkward whenever the robot shows off his rather unimpressive functions.

In their respective relationship charts, K1-B0 comments "I'll give you a hand." about Shuichi, while he comments "A dryer..." about K1-B0.

Danganronpa V3/Free Time Events
In Their First Free Time Events, K1-B0 wants to learn more about the teenage experience of humans, and thinks that relying on Shuichi to help him would be a good idea, so he proposes to Shuichi to spend his free time with him, to which, if the player accepts, Shuichi and K1-B0 will spend some "teenage time" together. K1-B0 then assumes that Shuichi has some interest in the robot since he came to spend time with him, to which Shuichi answers that he is a robot, so he finds him somehow interesting. After that, K1-B0 says that curiosity is a very useful human ability, and that he shall humor Shuichi as a robot. After Shuichi makes a comment to himself on how he thinks K1-B0 is talking down to him a little, K1-B0 starts explaining his functions. So K1-B0 starts to tell Shuichi his history and his visual function, explicitly trying to impress him, but gets easily offended when Shuichi describes this function as "pretty normal". He then says that his next function will definitely impress Shuichi, and tells him to raise his hand. Shuichi is then surprised and asks him if he heard well, and K1-B0 tells him that he wants Shuichi to put his hand in front of his mouth, what Shuichi does. K1-B0 then starts loading by screaming, and Shuichi thinks "...What the hell is this?". Shuichi then realizes that a lukewarm breath has started to touch his hand, and comment on the fact that K1-B0 is a robot, so maybe not "breath". When K1-B0 then tells him that his breathing has the function of a dryer, Shuichi answers "Ah...I see..." awkwardly. After K1-B0 introduces the rest of his functions to Shuichi, he thinks inwardly how K1-B0's breathing felt wierd, and does not know about his other functions. K1-B0 then tells Shuichi not to be too surprised, because after all he is the Ultimate Robot. K1-B0 then talks to Shuichi about his past and how grateful he is to his father, Professor Idabashi, for making his life a life of comfort, to what Shuichi respond that it makes sense. The FTE ends with K1-B0 boasting, and Shuichi thinking that maybe Miu could appreciate the mechanics of K1-B0.

In their 2nd FTE, K1-B0 asks himself about the hidden places in the school. If the player chooses to spend time with K1-B0, he and Shuichi will spend the next few hours exploring the grounds together. Their 2nd FTE starts, and K1-B0 thinks that Shuichi is very fascinated by him and that it can be understood, and says that in all the world, there is no robot as impressive as him. Shuichi then wonders why K1-B0 is talking to him like that, but thinks right after that K1-B0's technology is indeed pretty amazing. He then asks the robot if he knows why Professor Idabashi created him, to what K1-B0 replies that he is the sum total of his research, and that all of its knowledge and expertise has been applied into the creation of a more human robot than any has come before. After K1-B0 told Shuichi about his past with his father and his ability to feel human emotions, Shuichi seems to understand K1-B0 a little more, and internally thinks that he had no idea that he could have experienced something so incredible, and that he really is the Ultimate Robot. K1-B0 is then offended and tells Shuichi to reconsider his attitude towards him in the future. Shuichi answers "Haha... Yeah. Got it, Keebo." before returning to his room.

Bonus Modes
During the non-canon Love Hotel Event, K1-B0 wonders about the meaning of love and asks Shuichi to be his lover so he can learn about those emotions. The robot goes overboard with listing typical things lovers do together and Shuichi calms him down by saying that maybe they shouldn't be in a relationship if K1-B0 doesn't truly like him. K1-B0 turns unhappy and assumes he was rejected, but Shuichi tells him it's not like that. K1-B0 then confesses that he might have fallen in love with Shuichi and wishes to exchange warm words and hold hands with him. They both feel nervous, but decide to hold hands, which makes them feel calmer.

If K1-B0 has a good time with Shuichi during the bonus mode Love Across the Universe, he wouldn't like to go back to the dorm and wishes to spend more time with Shuichi like most students would like; He explains while blushing shyly that his chest feels warmer when he is with Shuichi and he feels very calm. K1-B0 also is one of the few students to have a more platonic love hotel. While he wishes to be Shuichi's boyfriend, all he wishes to do is hold hands instead of anything more sexual. Shuichi easily takes up this role for K1-B0 and even gently corrects a few of his misconceptions about love.

Fanon
The ship sailed as a result of Shuichi being the main protagonist of New Danganronpa V3: Killing Harmony and K1-B0 being the protagonist in-universe, for the audience of the game. Their interactions in bonus modes also helped to fuel the ship more. While the ship has a considerable number of fanfictions on Archive of Our Own, it's still less popular than certain other ships involving the two, such as Kiiruma or Saimatsu. Shippers may also appreciate K1-B0's protections of Shuichi while attempting to blow up the school. Many are also drawn in by the love hotel, as it is often seen as cute and charming.
