Website for Anison singer Eir Aoi hints her possible return?

Eir Aoi, the popular Anison singer known for her work on the themes for KILL La KILL, Fate/Zero, Sword Art Online, and The Heroic Legend of Arslan, has been in hiatus ever since her November 2016 two-day concert at Nippon Bodukan due the undisclosed health issues. Now, after 15 months of inactivity, her official website shines with a blue light, which may be received as her possible return. Nothing else is on the site outside of the blue light. A close eye will be kept to see what, if anything, may arise.

“Tsubasa” is the last single from Eir Aoi before her announced hiatus. The single was released July 20, 2016 and used at the opening theme to the second season of “The Heroic Legend of Arslan.”
