Polyshow

Polyshow is the POLY ship between Emu Ootori, Nene Kusanagi, Rui Kamishiro and Tenma Tsukasa from the Project SEKAI fandom.

Fanon
Being from the same band, WonderlandsxShowtime, the four characters spend a lot of time together, and have several events dedicated to them. Because of how close the four of them are, the fandom started shipping them, as well as some other individual ships between them. It's not rare for a band in the Project SEKAI fandom to be shipped all together.

This poly relationship regroups a lot of other ships, known as : Emunene, Tsukaemu, EmuRui, RuiKasa, Ruinene and Tsukanene.
