New song BLUE will be used to promote NTV's coverage of 2018 FIFA World Cup
2018 FIFA World Cup will start on 14th June which will take place in Russia and Tegoshi has been appointed as NTV's main newscaster to cover the event
For now , it's not known when BLUE will be released as NEWS's next single

Wouldn't surprise me if BLUE will sound in the same vein as NEWS's past sports theme driven songs
