Project Sekai: Colorful Stage! feat. Hatsune Miku has been steadily expanding its music library and event offerings through June 2026. On June 5, the game added the song "Raspberry*Monster" with both a SEKAI version by Hatsune Miku and Leo/need and a Virtual Singer version by Hatsune Miku, along with a 3DMV released on the official YouTube channel. A week later, on June 12, the game added "Eien Hanahadashii," composed by Shishi Shishi, available in a SEKAI version by Megurine Luka and Vivid BAD SQUAD and a Virtual Singer version by Hatsune Miku, also with a 3DMV.
On June 21, the game launched a collaboration with the Deemo and Cytus series, running through July 3. The event includes a login campaign, a premium gacha, a stamp mission, and the addition of the song "SAIRAI" by Shinichi Kobayashi. The same day, the game began the "HAPPY BIRTHDAY Kamishiro Rui 2026" event, running from June 21 to June 26, with birthday-limited items, a Celebration Tree mechanic, and two birthday gachas.
Outside the game itself, the Netflix animated film Super Kaguya Hime! has drawn strong support from Vocaloid fans, with an article arguing its narrative structure mirrors the creator-singer-virtual diva relationships that define Vocaloid culture. The film is not a Vocaloid-themed work, but its resonance with fans of Hatsune Miku and the Project Sekai ecosystem reflects the broader community's engagement with virtual diva narratives.
