It’s rather galactic funky beats.
Go Rush!!’s second year comes with a new OP and ED!
The new Opening theme is “Soul Galaxy”, sung by BRADIO, who some might know for Flyers, the theme song of Death Parade. BRADIO is a Funk Rock group.
The new Ending theme is “Cosmos”, sung by by Taichi Mukai, who might be known for Bravest, the last theme song of Dragon Quest: The Adventure of Dai. Mr. Mukai appears to specialize in R&B infused rock.
