In-Game

Matsushima Michiru is a loved, respected, nationally-famous idol, worthy of singing on the same stage as the legendary Kazami Kazuki... in her own dreams, at least. In reality, she's a complete nobody, only able to perform in a dingy basement bar on the weekends for crowds numbering in the single digits.
