Project SEKAI Fanfiction
SEGA and Colorful Palette's rhythm game pairs Hatsune Miku's virtual singers with five original units of Tokyo teens, each with a secret world born from their true feelings. Fanfic writers gravitate to the game's heavier event stories — Mafuyu's controlling mother, Ena's artistic envy, Rui's isolation — making Niigo (25-ji) angst the archive's gravitational center, balanced by Wonderlands x Showtime chaos and More More Jump idol comebacks. The fandom skews young, productive, and deeply sincere about mental-health narratives.

Popular Project SEKAI Ships
AkiToya
Aoyagi Toya/Shinonome Akito
Vivid BAD SQUAD's vocal duo is built on a promise: Akito's burning ambition to conquer Vivid Street, and Toya, the classical-music defector who pledged to chase it with him. Project Sekai writes them as two halves of one sound, each insisting the other's voice is what makes theirs matter. The fandom turned that canon codependence into its most-written ship.
4,000 works →
MizuEna
Akiyama Mizuki/Shinonome Ena
Niigo's prickly artist and its secret-keeping designer share late-night calls, mutual insecurity, and a friendship that survives Ena learning the truth Mizuki feared would end everything. Project Sekai built their arc around acceptance, and the fandom read the devotion between the lines. It is the game's flagship pairing for messy, fiercely loyal girls.
2,500 works →
RuiKasa
Kamishiro Rui/Tenma Tsukasa
Wonderlands x Showtime's mad-scientist director and its future-star lead built Project Sekai's biggest ship on event stories where Rui's inventions only ever fly with Tsukasa aboard. Their canon partnership is two dreamers writing each other into every show.

EmuNene
Otori Emu/Kusanagi Nene
Phoenix Wonderland's relentless ball of 'wonderhoy' and her stage-frightened gamer best friend complete Wonderlands x Showtime's double act. Canon stories keep showing Nene quietly managing Emu's whirlwind while Emu pulls Nene into the spotlight.
