Singer Nana Kitade is continuing to promote the animated series "Ruby Gloom," this time with a new single released under the name of the show's title character.

Ruby Gloom is an apparel brand that originally spawned a cartoon in Canada, which is now broadcast in several countries. It started airing in Japan last month, though the brand began being promoted last year through a tie-in with Kitade's second album, "I scream."

Kitade's new song is titled "Siren," produced and arranged by Marty Friedman. It is being used as the show's ending theme, and will be released under Ruby Gloom's name on March 26.
