On September 25, during the final show of their fan club tour in Fukuoka, Golden Bomber announced a series of upcoming activities, including a new single, Christmas concerts, and a nationwide tour in 2027.

Bassist Jun Utahiroba will also make his solo debut with "Umanushi ni Natte yo," set for digital release on October 21. Utahiroba originally wrote and performed the song for his solo segment during the group's fan club tour, and it was later decided to release the track following requests from the other members and staff.

Golden Bomber will release the double A-side single "Byomei wo Tsukete Kure / Zandaka Zero" on December 2. The group will then hold their Christmas concerts, Golden Bomber Christmas Live ~Saikyo-sen Dai Bakuha~, at Omiya Sonic City in Saitama on December 22 and 23.

The group also announced a nationwide tour for 2027, and a live DVD featuring the September 25 fan club tour finale.
