This is the fourth installment of YOASOBI's iconic series, "THE BOOK."

Rather than simply using the number "4," we have titled this volume "for" to express our deepest gratitude to all the fans who have supported YOASOBI throughout the journey of "THE BOOK" series.

This album features the new collaboration track with Overwatch.

As part of our initial project reveal, we are excited to share a sneak peek of this collaboration design—available only in the US. The final product will feature the full tracklist and credits. Cover artwork to be revealed soon!
