Kadokawa has released a second main promotional video for the upcoming anime adaptation of The Other World’s Books Depend on the Bean Counter (also known as Isekai Office Worker: The Other World’s Books Depend on the Bean Counter), offering a fresh look at the series and previewing its highly anticipated opening and ending theme songs. The new trailer, revealed during Animate Girls Festival 2025, builds excitement for the anime’s January 2026 premiere.
Unveiling the Theme Song Artists
The latest promotional video confirms the artists performing the crucial opening and ending theme songs for The Other World’s Books Depend on the Bean Counter. Japanese rock band kobore will perform the opening theme, titled “Magic,” while actor and singer Win Morisaki will take on the ending theme, “Back to Back.” Both tracks are expected to complement the anime’s unique blend of isekai, office work, and boys-love elements.
“Magic” by kobore: Setting the Tone
kobore’s “Magic” is set to open each episode, likely providing an energetic or perhaps mysterious introduction to Seiichirō Kondō’s extraordinary new life. The band’s style is anticipated to infuse the series with a distinct sound, engaging viewers from the very beginning.
Win Morisaki’s “Back to Back”: A Reflective Close
Win Morisaki’s “Back to Back” will serve as the ending theme, traditionally offering a more reflective or emotional conclusion to each episode. Morisaki is also joining the anime’s cast as the character Ciro, further connecting him to the production.
