The BUMP OF CHICKEN Band Collaboration was a collaboration with Fujiwara Motoo's band, BUMP OF CHICKEN. The collaboration involved two of their songs being added to Project SEKAI, which were both covered by Leo/need and received 2DMVs. Both songs acted as the final two entries to the 1st Anniversary Song Campaign, despite being announced separately from the campaign.
