📖 How mirumerun Came to Be
The journey of mirumerun hasn’t always been smooth sailing.
Both members had previous experience with music, but due to various life events, there were periods when they had stepped away from it completely.
They also shared a painful setback: both suffered from physical ill-health and illness that made playing instruments properly impossible.
It was during this time that they discovered VOCALOID—a revelation that inspired them to give music creation another chance, ultimately leading to the birth of mirumerun.
Bit by bit, they began creating tracks, publishing their work, and continuing their musical journey to this day.
