K-pop sensation BTS will release its first song as a group in 11 months. 

Thymos Media, the producer of the forthcoming SBS TV animated series "Bastions," on April 14 said the boy band recorded the show's theme song.

The song is the first project by BTS as a group since it released its anthology album "Proof" in June last year. 

The official opening sequence of "Bastions" is available on BTS' official social media and the series' YouTube channel and website to announce the boy band's participation. 

"Bastions" is about a group of rookie superheroes in a world where superheroes compete for popularity. The young dynamos emerge as full-fledged heroes after saving Earth from a crisis by uncovering the identity of a villain responsible for environmental pollution.

The series' premiere on SBS TV is slated for May 14 at 7:30 a.m.
