Anime voice actress Kotori Koiwai (Renge Miyauchi in Non Non Biyori, Nono Daichi in Aikatsu!) has started offering 30-minute healing background music that anyone can use for free.
She has been active as a songwriter/composer, and recently set up a home recording studio for professional use.
In addition to providing the music, Koiwai also worked on editing of the sound clip.
