Project SEKAI Fanon Stage! feat. Hatsune Miku (also known as FanSta or FNST), is a fanmade version of Project SEKAI COLORFUL STAGE!
Development[]
On August 8, 2025, Ellee (then known as Ellee DeLonge) posted about an idea - a version of Project SEKAI COLORFUL STAGE! but the canon units are replaced by wiki units. Sakura⚝Stars (at the time was named Blooming⚝Stars) was gonna represent N25, but after seeing the unit page for the DISMAL DREAMERS, Ellee switched B⚝S's representing unit to Vivid BAD SQUAD.
This blog post about FANON STAGE! was made on August 12, 2025, marking the project's official start date.
Story[]
The game is set in Shibuya, Tokyo. Ellee, Yuki, May, Reverie and Angel seperately stumble upon seeing a screen of Hatsune Miku.
Upon returning home, the five discover a song named "Untitled" on their smartphones. Out of curiosity, they play the song, only to be surrounded by a white light and transported to an unknown place. Five variants of Miku stand in front of them, welcoming each one to SEKAI and inviting them to sing together.
Characters[]
VIRTUAL SINGERS[]
Similarly to the original, it features Crypton's Piapro characters: Hatsune Miku, Kagamine Rin, Kagamine Len, Megurine Luka, KAITO, and MEIKO. These characters take the form of VIRTUAL SINGERS (also known as VOCALOIDS). However, it also features flower, MAYU, Fukase, SEKAI and KAFU.
