Young anisong singer ReoNa is ready for the release of her fifth single Nai Nai on May 12. This time around, the vocalist lends her soothing voice for the ending theme of the anime adaptation Shadows House. ReoNa’s shadowy silhouette visuals for the single lend inspiration from the gothic style anime. However, we will have to wait until April 10, when the anime premieres on TV, to hear a short version of the single for the first time.

In the visual department, ReoNa gets inspiration from Shadows House in both her promotional photos and the artwork for the single as we see the vocalist posing with her own shadow.

Shadows House shows the lives of a group of shadows who wear aristocratic clothes and live in a mansion. Each faceless shadow employs a living doll to serve them. The story follows living doll Emilyko as she learns to provide servitude to Kate Shadow.
