Shinra but-show

The title track "Shinra Bassho" was written and produced by Kenmochi Hidefumi (of Wednesday Campanella), who has also created songs for the group such as "Sagashimono," "Try-jin," and "YOIMIYA."
With its festive atmosphere that evokes the beginning of a grand celebration, the song is irresistibly danceable and guaranteed to bring audiences together in excitement during live performances.

"do you jokyo?" was created by the same team behind the group's 2017 song "Bibibi Bishojo", with lyrics and composition by Yamamoto Sho and arrangement by Genji Miyano.
The song playfully depicts the "situation" (jokyo) of BATTEN GIRLS after they literally "moved to Tokyo" (jokyo) in 2025, resulting in a cute, upbeat, and energetic track.

In addition, "Bibibi Bishojo (Ririri Remix)", an updated 2026 version of the fan-favorite song "Bibibi Bishojo" - also written and composed by Yamamoto Sho has been newly recorded for this release.
The remix was handled by Peanata, a Vocaloid producer, composer, and music producer, giving the beloved track a fresh new sound for 2026.
