The title is "Answer" and the release date is still unknown. The song will be used as the ending theme for anime 'Beelzebub', which starts airing 2011/1/9 on NTV.
Not much is known for now, but I went to check up on this anime, never having heard of this particular title before. "Beelzebub" is an action comedy (click on the link for Wikipedia). I looked out for reviews of the manga, most people seem to like it and rate it high, so this sounds like it'll be a fairly promising boost for no3b's sales and recognition. This will mark no3b's
Personally, I am already getting excited just from the song title. It sounds so cool.
