Polyniigo

Polyniigo is the poly ship between Kanade Yoisaki, Mafuyu Asahina, Ena Shinonome, Mizuki Akiyama from the Project SEKAI fandom.

Canon
Kanade, Mafuyu, Ena and Mizuki are all part of the music circle 25-ji, Nightcord de/Nightcord at 25:00, with Kanade/K being the leader/composer, Mafuyu/Yuki the lyricist, Ena/Enanan the illustrator and Mizuki/Amia the music video creator. The group circle name is formed by them having Nightcord (Discord) call/chat sessions everyday at 25:00 (1 AM) to discuss about their music and others. They all attend different school classes, Kanade attending Online High School, Mafuyu attending Miyamasuzaka Girls' Academy, Ena and Mizuki both go to Kamiyama High, however Ena takes night classes while Mizuki does normal classes. Kanade, Mafuyu and Ena are second-year high school students, while Mizuki is a first-year.

The four used to individually make their own content before they formed 25-ji, Nightcord de., until Kanade had listened to Mafuyu's song. She quickly rushed to make an account to message Mafuyu if she had wanted to make music together, later on Ena joined, then Mizuki. At that time, none of the 25-ji members had actually known each other, not even knowing their real names and only referred to each other by their Nightcord handles (K, Yuki, Enanan and Amia), as they used the chat tool Nightcord (Discord) to communicate.

The group has an area conversation at the shopping mall with all four of them. Ena and Mizuki are checking out outfits while Mafuyu and Kanade note that the former duo doesn't want to leave the store. Kanade thinks to herself that they should just go home since they already had a party to celebrate the release of their new song. Ena asks if Kanade likes a hat, adding that she thinks the hat would look fabulous on Kanade. Kanade says that she isn't the type of person to go out while Mizuki talks to her. Mafuyu tells Kanade to have fun and not worry about her; Kanade asks to be pitied.

Main Story
The main Niigo story starts off normal, them creating music and doing music things. However, one day when Yuki doesn't attend their Nightcord session although Yuki and Amia were in a call just that evening, the three find it confusing but shake it off as sometimes people fall asleep easily. This does not conclude the mystery as from that day Yuki has not been online for the next week, the members start to worry for Yuki's safety and health. Since they've only communicated by voice and have never actually seen each other it was difficult for them to figure out what had happened to Yuki, but Amia found something interesting in the shared folders. The file had seemed to be a music file created by Yuki the day she had went missing, the title of the file was named "Untitled". The three decided to take a listen to the file, but what only played was a shining glowing light from their screens, which brought them to Yuki's SEKAI. That day was the first time K, Enanan and Amia had seen each other's faces, excluding Amia and Enanan as they were already following Enanan's selfie social media before the strange events had occurred.

The three were extremely confused on where this place was and how they even got there, the first thing they decide to do is try to find a way back home, so they start to walk around until they could find something. After finding nothing in such a empty, strange place, they decide to instead introduce themselves, which ends up them leading back to the topic of Yuki. A hologram finds them and approaches them, which Kanade seemed to recognize, the hologram calls herself Miku, and tell the three that they need to find and save the girl.
