Aoi Eir I'm Aoi Eir, the artist in charge of the ED song of "Sword Art Online: Alicization -War of Underworld-". I had the pleasure of singing "Iris" in the 1st cour, so I'm very grateful to be able to sing the ending theme once again. The new song titled "I will..." is a ballad with a spectacular development, which is based on the theme of walking together while getting close to the hearts of the people you care about. I hope that "I will..." will be able to reach fans' hearts through SAO.
