About the game
“One Song, One Life” is a rhythm adventure game where your performance changes both the music and the story.
Every note you hit determines the path of a girl chasing her dream of becoming the best net artist and standing on the same stage as her idol.
You’ll play as Sumire Kirishima, a 19-year-old girl from Tokyo. Raised by her father after her parents’ divorce, Sumire is talented but selfish—willing to put everything on the line for her goals, even at the cost of others.
As she climbs the ladder of the music world, she’ll face temptation, manipulation, and betrayal.
But don’t worry—no matter how deep she falls, remember:
Life itself is just one song.
