ONE N' ONLY release their 2nd major album! -- Their 2nd major-label album. The lead track "Golden Sun" is ONE N' ONLY's loudest-ever "dazzling dopamine song," featuring a catchy chorus that makes you want to shout "Go! Go!" along with it, followed by waves of aggressive rap and emotional vocal passages that will have you shouting "Mega Moriagare!" before you know it. The artwork also fully embraces the "golden" aesthetic of "Golden Sun." The album contains 12 tracks in total, including "WARAiNA," the title track of their 2nd major single released in April, "Samba de Night Fever," which has continued to attract attention mainly on social media since its April release, as well as newly recorded songs such as "CRUSH ON YOU," the opening theme song of the drama "Ao to Midori," co-starring NAOYA (Naoya Kusakawa).
