Popstar Utada Hikaru was taking time off. She hadn't put out a new song since 2010. Until now.
Utada is lending her talents to the new Evangelion feature film, Neon Genesis Evangelion: Q 3.0 You Can (Not) Redo. She's such a big fan of the series, that she couldn't turn down the offer to do the film's theme. The name of the tune is "Sakura Nagashi" (桜流し).
