MakoShinoMitsu

MakoShinoMitsu is the poly ship between Makomo, Shinobu Kocho and Mitsuri Kanroji from the Demon Slayer fandom.

Canon
While Makomo didn't meet them, Mitsuri and Shinobu are both fellow Hashira. Mitsuri and Shinobu are the only two Hashira that are female. And both of them have great respect for each other. As Shinobu believes Mitsuri is cute and cheerful. And Mitsuri also believes that Shinobu is very cute and even states that Shinobu is more composed than her, despite being older. Mitsuri also wishes to spend more time with Shinobu, but unfortunately cannot because due to them both being pillars, they are very busy and don't get many opportunties to interact. But unfortunately Makomo was killed years prior to the current story, so she couldn't meet Shinobu nor Mitsuri. But Makomo is alive in Demon Slayer Academy which is an alternate universe where our lovely Demon Slayer characters are in school. Makomo and Shinobu are seen in the same scene together. When Zenitsu Agatsuma admires how the two looks after already previously admiring how Nezuko Kamado was dressed. But Mitsuri does not make a single appearance in the Demon Slayer Academy. So there couldn't be a scene with all three of these Demon Slayer Characters all together

Fanon
is a rarepair among the fandom. Likely because the three don't have any scenes all together. Not to mention that Shinobu and Mitsuri never met Makomo so finding people who actually support this ship is very rare. People who enjoy Femslash content would more prefer to ship Shinobu and Mitsuri by themselves. Also there are far too many ships that overshadows this ship that include these characters. Such as ObaMitsu, GiyuShino, ShinoMitsu and SabiMako.

Despite the ship being very rare to be shipped by fans. It still has a small fanbase and some support from Demon Slayer fans. One potential reason this is shipped is because people who ship both MakoShino and ShinoMitsu, chooses to ship them together to avoid having to choose. Individuals also tend to believe that they are all attracted to females in a way and believed that had Demon Slayer taken place in more modern times... Each of these three would have a sexuality that would have a sexuality that includes females. Makomo's being Lesbian, Shinobu's being Bisexual and Mitsuri's being Bisexual or Pansexual.

Reasoning for this is that fans theorized that there's a chance that Makomo would've been a lesbian had she been alive currently. While the fandom mainly tends to ship her with Sabito and it is true that the ship between them is rather popular on Makomo's side but... Makomo and Sabito were both adopted by Urokodaki, so some people view their relationship as a brother and sister one. So, some fans believe that they would have more of a family bond. So fans who don't ship them romantically believe that Makomo would possibly not end up falling in love with Sabito if they were alive in the current timeline.

For Shinobu, several fans tend to also ship her with female characters. This is because some people also theorize that Shinobu is bisexual and is romantically attracted to both genders. This is mainly because of the moment where she slept close to Yae and she also tends to flirt with male characters. But even so, people believe that out of the two, that Shinobu has a preference for women.

Some believe this is because in the Butterfly Mansion (Shinobu's residence), everyone whom also lives there are also females. So people often believe that Shinobu is less attracted to men because of this but still regards that she could end up dating either gender.

For Mitsuri, a main reason is that several fans believe that her sexuality is Bi or Pansexual because of her being titled as the Love Hashira. Though she's canonically in love with Obanai. People tend to believe that since Shinobu is next in line for one of her closest friends. They say that she either was romantically attracted to both of them, or that she formerly had feelings for Shinobu at one point and believed that the ship between her and Shinobu should've been stated as Semi-Canon rather than Fanon.

But other fans still hypothesize that in other scenarios, Mitsuri could've ended up having romantic feelings for anyone if they confessed to her, regardless of their gender identity.

In terms of all three of them. Few believe there could be a scenario where these three end up together. But some fans do believe that if Makomo were to survive. She would likely grow close with the both of them if she had gotten the opportunity to meet them. Fans who don't ship them romantically would think that Shinobu and Mitsuri would view Makomo as cute and that all of three of them would have that similar impression on each other, especially if Makomo became a Hashira along with them. So though it's a rarepair the ship still has at least some support from fans overall both platonically and romantically.
