Aoi Eir has announced that she will be leaving both her agency Guan Barl and labelSACRA MUSIC. 

Since releasing her album "KALEIDOSCOPE" in January, Aoi has been on hiatus due to health issues. On her official website, she expressed, "I am very grateful for the staff who have been looking after me for a long time. I am also grateful from the bottom of my heart for everyone who have always supported me during that period." She added, "From now on, I would like to carry out my activities slowly while considering my health. I will do my best so that I will be able to show everyone my grateful feelings again." 

To coincide this announcement, Aoi's song "Aoku, Aoku" has been released on streaming services. This is her latest original song that was used for Smart Pachinko Sword Art Online.
