The 5th installment of the 'Artist Collaboration' project, featuring popular artists creating original songs for the idols, will be released on Thursday, June 25.

The 5th collaboration features 'Hikari Saku', a new song by Shota Horie, Uyachabou, and Daisuke Okamura, performed by the idol unit 'Mirai Link'—comprising Makoto Asahi (CV: Murasame Kaka), Serina Koharu (CV: Mizugiri Keito), and Azuma Umikaze (CV: Aoi Aoi)—a label full of potential despite their inexperience.

On the release day, an MV featuring original illustrations will be published on the official YouTube channel. The full version of the song will also be available in-game.

Further updates will be shared sequentially on the official X (@s_i_project).

About the Artist Collaboration Project

This initiative invites popular artists active in idol content to write original songs for the game's idols. Six unique songs, each tailored to one of the game's six labels, will be released with accompanying MVs featuring newly drawn illustrations. The first collaboration was by Higedrivers, the second by Funta7, the third by Gesshoku Kaigi, the fourth by Yukacco & Genki Hikota (Hifumi, inc.), and the fifth by Shota Horie, Uyachabou, and Daisuke Okamura.
