Sakura no Ato (all quartets lead to the?)

"Sakura no Ato (all quartets lead to the?)" is a song by UNISON SQUARE GARDEN, released in 2013 as the band’s fifth single. It opened the TV anime Yozakura Quartet: Hana no Uta (夜桜四重奏 -ハナノウタ-), produced by Tatsunoko Production. Tomoya Tabuchi wrote the lyrics and music, and UNISON SQUARE GARDEN handled the arrangement.

The track moves with a bright, urgent J-Pop pulse colored by the band’s rock attack. Quick guitar lines, a tightly locked rhythm section, and clipped vocal phrasing keep the verses in motion before the chorus opens wider without losing speed. That balance of bustle and precision gives the song a restless, street-level energy.

That energy suits Hana no Uta’s mix of everyday city life, supernatural friction, and sudden action in Sakurashin, where humans and youkai live side by side under strain. The single appeared on November 6, 2013 with "over driver" and "uno step" as B-sides, later reappeared on the album Catcher In The Spy as track 2, and reached No. 10 on Oricon’s weekly chart.
