[All] Collaboration song 'Dark Arts' to be released on the 15th

Battlegrounds will sequentially release teasers and main content. Starting with the collaboration teaser video on the 3rd, the music teaser will be released on the 5th, the main film on the 9th, and the full version of the main film will be released simultaneously with the music release on the 15th.

I'm so looking forward to the 15th. I want to see it soon~
