Mizumafu

Mizumafu is the non-binary ship between Mizuki Akiyama and Mafuyu Asahina from the Project SEKAI fandom.

Canon
Mizuki is a first-year high school student and Mafuyu is a second-year high school student as well as members of the music circle Niigo (Nightcord at 25:00), where Mizuki is their animator under the name "Amia" and Mafuyu writes the lyrics for the group's songs under the name "Yuki." Mizuki is cheerful, always wants to "enjoy their life while they can" and enjoys teasing their friends and groupmates alike, while Mafuyu, when she's not pretending to be her "honor student" self, is apathetic, stoic and speaks in a low voice.

While the group's other two members' Kanade and Ena's struggles are related to their artistic talents, Mizuki and Mafuyu suffer due to their identities. Mafuyu, a beloved ace student who does her best to live up to her parents' expectations, started doing everything her parents pushed her onto (such as studying to become a doctor instead of a nurse) and in the process, ended up becoming broken, forgot what her dreams are and lost sight of her own identity. As such, she tries to find herself by making songs. Meanwhile Mizuki, although appearing as confident outside, is ostracized and treated like a weirdo due to their appearance, when all they want to do is dress up and present themselves in the cute clothes they love a lot. Due to a past incident, Mizuki is known to have a secret they refuse to tell anyone else (in order to avoid getting hurt like in the past).

Main Story
In Niigo's Main Story, Mizuki and Mafuyu are shown to have a one-on-one conversation in Chapter 4. They meet up at Nightcord earlier than usual and are both surprised. When Mafuyu mentions she had a short schoolday and as such wants to be able to do work she can't normally do on weekdays, Mizuki tells her she's really serious about the circle's work, and Mafuyu tells her she needs to do her best as well since the others work really hard. Mafuyu's mother enters the room and asks how Mafuyu's day went. When Mafuyu answers, her mother tells her that she should turn down her friends' request for help if it's too much of an incovenience, and how she should rather spend time with people who could challenge her so she could value her time more. Mizuki apologizes for eavesdropping their conversation and then asks if Mafuyu's mother really told her to not be friends with girls who aren't on her level. Mafuyu says she rather meant that she should study with the smarter girls at times too, and Mizuki questions it more, saying they wouldn't like it if others tried to force their values on them or say how their way of doing things is better than Mizuki's, but also clarifies that they aren't implying Mafuyu's mother did so. Mafuyu goes silent and then tells Mizuki how it doesn't bother her. Mizuki is convinced for the time being and apologizes for taking too much of her time before going back to work.

After the other members run into Mafuyu in the Empty SEKAI, who says she knows they've all wanted to disappear before as well and ends up causing a rift within the group, Mizuki starts talking about Mafuyu with Ena in Chapter 14. Mizuki mentions them overhearing Mafuyu and her mother's conversation and mentions the things they had deduced before and how Mafuyu claimed it didn't bother her. Mizuki then explains how they believe Mafuyu - as mentioned before - changed herself according to others' expectations of her in order to become the "good girl" she is, and the pressure is starting to be too much for her to handle, leading to her wanting to completely disappear. Mizuki mentions how they can understand Mafuyu's struggle and how sad her "transformation" to her current self sounds. When Mizuki says they want to talk to Mafuyu again, the latter uploads multiple depressing songs in a row, showcasing Mafuyu's current mental state and shocking both Mizuki and Ena.

When the whole group visits Mafuyu in Chapter 18, Mizuki says they understand how the former feels and she's free to disappear if she wants, since only Mafuyu can truly understand what goes on in her mind. Before Mafuyu can speak more, Mizuki continues and says they're quite alike, in regards to not knowing whether to forcing themselves to change for the people around them to the point where nothing matters anymore, and how it would be sad if Mafuyu actually went and disappeared.

Secret Distance
After the group arrives to the abandoned school in Chapter 5, Mizuki starts explaining the urban legend behind it, how the ghost of a dead student haunts the music room. Upon hearing that the student killed herself due to the tremendous pressure set upon her, Mafuyu comments that it might have been the best and easiest choice for her. She marches towards the school, and the group runs after her. Mizuki starts searching the other way before realizing she might have gone to the Empty SEKAI. Mizuki arrives there, spots MEIKO and then asks if she had seen Mafuyu around, but MEIKO tells Mizuki the Virtual Singers would have known if she had come in. Mizuki sighs in relief, saying that they thought Mafuyu might have come inside due to being bothered about the urban legend. Mizuki returns to the real world, and is relieved once again after Ena rushes to them, telling that Mafuyu was just wandering around the area. The rest of the group then spots a sakura tree and find Mafuyu watching it, who is also unable to take her eyes off it.

Mirage of Lights
In Chapter 3, Mafuyu enters Empty SEKAI with her childhood photo album in hands. Upon arriving, she finds Mizuki there with Rin, who is complaining that Mizuki came in only to attach a new corsage they had found on her skirt because it was "so cute." Mizuki asks if Mafuyu is feeling okay and if she'd rather be left alone. Mafuyu tells them "no" and they are happy, before Rin reveals that Mizuki has been coming to the Empty SEKAI more often lately. When Mafuyu asks for the reason, Mizuki hesitates a bit before explaining that they find it comfortable because it's quiet and empty, how nice it is to go there when they need to think or whenever they just need to go somewhere quiet. Mizuki changes the subject by asking about Mafuyu's album, the latter explaining she was looking through it with her family earlier and she wanted to know just why her chest hurt when she looked through it. Mizuki suggest they look at it together, quoting Kanade's words from earlier and how they might find some hints about Mafuyu's feelings.

Mizuki sees a picture of Mafuyu doing archery and is shocked upon finding out it was taken at the local tournament where she ranked second. Mafuyu claims she only participated because she was asked to, but Mizuki keeps praising her. Upon seeing a picture of the 5-year-old Mafuyu smiling, Mizuki deducts that she has changed completely, how genuine her smile is compared to the one she wears while in her honor student mode. When Mafuyu says she doesn't understand, Mizuki tries explaining there might be a big difference for why she was smiling. As Mafuyu thinks she might find the key to her feelings from the Carnation event, her cold comes back and she starts swaying only to claim she is okay. Mizuki tells her to take it easy and how they can search for clues when she's feelings better. Though Mafuyu initially declines, she ultimately leaves the SEKAI.

Mizuki worries after her, and when Rin asks how Mizuki was able to deduct the part about Mafuyu's smile, they explain that they have been perceptive since they were young, sometimes to a fault to the point where they were afraid of getting close with people, or overthinking how others might have perceived Mizuki in their heads. The chapter ends with Mizuki wishing that Mafuyu will be able to find her true self soon.

At the end of the after-event Virtual Live, after Mafuyu says she won't give up, Mizuki ponders in a quiet voice whether they'll be able to face their problems one day if they don't give up either.

Fanon
Mizumafu isn't that popular but it isn't a rarepair at the same time. It is mostly overshadowed by more popular ships like Mafuena, Kanamafu and Mizuena. Its unpopularity mostly stems from their limited interactions. In fanworks, the two are usually portrayed as their canon selves, with Mafuyu being poker faced or blunt, and Mizuki teasing her or being friendly and close, and sometimes being surprised by the things Mafuyu does or says.

It is currently Mafuyu's 3rd, and Mizuki's 4th most written ship on AO3.

 * Mafuyu has a diluted sense of taste while Mizuki can't handle anything that is too spicy or hot. This is especially shown in an area conversation, where Mafuyu tries out the limited-time extra spicy french fry, only to comment it's only slightly spicy. When Mizuki tastes it afterwards, they freak out over its spiciness level, and Mafuyu asks if she should get them water.
 * In IDSMILE's 3DMV, Mafuyu's movements are shown to be more sluggish compared to everyone else, and she appears more emotionless as well. This is because IDSMILE, which is Mizuki's first center song, is a song about one's identity.
