"BEST" is the last single in the 5-month consecutive release series that began in August. As the lyrics of Grow up, released last year, say, "My past self has accumulated," it has been accumulated to this day. There are good times, difficult times, and tough times, but if things are good now, then everything is BEST. The beat for this song was composed by beat maker "Dotted Fuji" from Ibaraki City, Osaka, and TPI (Top Position In), and the beat was mixed by "NO TYPE9."
