Much of anime is about creating epic, fantastical universes for fans to escape into. And a powerful soundtrack, heightening emotions in just the right ways, is critical in achieving this. Enter Aira Yuuki. The majestic voice of this anisong veteran has soared over a sonically varied catalogue since 2007. She’s just as comfortable with restrained grandeur—as in the piano melodies of “Violet Snow” from Violet Evergarden—as she is among the pulsating electro-rock beats of “REINCARNATION BLUE” from BlazBlue: Alter Memory. Her full-throated vocals craft the key for unlocking doors to these worlds.
