With a solo live show at Ariake Arena scheduled for January 2026, DXTEEN releases their highly anticipated second album. The album includes the much-talked-about song "Ryo Kataomoi", praised as a Reiwa-era idol song with god-tier lyrics and used as the theme song for the drama "Shugaku Ryoko de Nakayokunai Group ni Hairimashita", as well as "Tick-Tack", the title track of the fifth single and opening theme for the drama "Yabusaka de wa Gozaimasen", the fourth single title track "Level Up", and the ballad "You", used as the theme song for DXTEEN's first starring drama "Saigo no Hokago", appearing on an album for the first time. Including additional new songs, a total of ten heart-pounding (Heart Beat) tracks are included. The Limited Edition B comes with a photobook. Includes one DX card (randomly selected from six kinds of Limited Edition B versions), and an application code (valid only in Japan).
