Project Sekai Adds syudou-Written Song Anti-Sainou
The addition pairs a songwriter known for darker vocaloid-adjacent material with a five-member cast spanning multiple Project Sekai units, a crossover the game's event structure does not usually produce.

Sega and Colorful Palette added syudou's newly written song 'Anti-Sainou' to Project Sekai Colorful Stage! feat. Hatsune Miku on August 27, 2026. The track is performed by MEIKO, Airi Momoi, Akito Shinonome, Nene Kusanagi, and Ena Shinonome. Players can receive it from the in-game Gift, and a 2D MV is on YouTube.
The new track arrives as a gift item rather than a purchasable song, which means every player can add it without spending in-game currency. The vocal lineup draws from three different groups: Airi from MORE MORE JUMP!, Akito and Ena from Vivid BAD SQUAD, and Nene from Wonderlands x Showtime, with MEIKO as the Virtual Singer.
syudou wrote both lyrics and composition. The 2D MV went up on the official Project Sekai YouTube channel the same day the song entered the rhythm game.
