Funk is active as a member of Umeda Cipher (currently withdrew) and has a brilliant career as a battle rapper, winning UMB Choice is Yours 2019, ADRENALINE 2018, and UMB 2017 runner-up. Tamai Kosuke has been friends with Funk since he was a teenager, and is himself a former member of Umeda Cypher and a runner-up at "B BOY PARK U20 2011." This is a song in which the two, known for their high skill, rap about their New Year's resolutions over a track that samples Japanese classics. The track produced by Tamai Kosuke is a trap arrangement of the Japanese classical music "Haru no Umi", giving off an old-fashioned but danceable atmosphere.
