G-MODE to Publish 'One Song, One Life'! New Demo Debuts at Steam Next Fest

G-MODE Co., Ltd. has officially announced its role as the publisher for 'One Song, One Life,' a new indie title planned by the music production company LOVE ANNEX and developed by C-Route. This innovative rhythm adventure game features a unique system where the type of notes hit by the player causes both the music and the story to branch. Players will guide the life of 19-year-old Sumire Kirishima (Sumire-chan), who aspires to become a top net artist to stand on the same stage as her idol. The narrative delves into the complexities of the music industry, including temptations, setbacks, and even being deceived by 'bad adults,' emphasizing the theme that 'life is but a single song.'

Targeting a 2026 release, G-MODE is providing full support, including development assistance. The game is currently participating in the June 2026 edition of Steam Next Fest (June 16–23 JST), where a playable demo is available. A new promotional movie released today features the heroine Sumire-chan introducing the game's highlights. The project features over 20 original songs, with LOVE ANNEX's Yudai Ota serving as development director and composer. Produce and scenario duties are handled by Takafumi Suda (Mizugaki) of C-Route, who aims to create a game that is highly engaging for both players and live-stream viewers.
