SPYAIR will be contributing the official theme song for the B.LEAGUE 2018-19 SEASON basketball league
Titled B-THE ONE , the song will be used to promote B.LEAGUE 2018-19 SEASON that will begin on 4th Oct until next May 2019
For now , it's not known when B-THE ONE will be released as SPYAIR's next single

Wouldn't surprise me if B-THE ONE will sound sports inspired & it might probably borrow elements from Imagination and/or I'm・A・Believer since both songs were used to promote the Haikyuu anime which's based on basketball
