Ryo Nishikido
"Life" is a fast-paced pop-rock song. It uses various instruments such as rhythm percussion, drums, guitars, a keyboard, and an electric bass. A string section also has a predominant part in the song's chorus, which is harmonized with an electric guitar during the chorus. For majority of the song, the verses are split into harmonies between Subaru Shibutani, Ryuhei Maruyama, and Shota Yasuda covering one section and Ryo Nishikido, Yuu Yokoyama, and Shingo Murakami in another. Ohkura has one solo, the bridge, which is accompanied only with strings. Shibutani and Nishikido open up the song, alternating between each other with " Absolutely / Absolutely ", before singing " I want to continue walking forward / without looking back " and ending with a falsetto, " Because it's still / Not over yet ".
