Houkago Princess‘ new single Himitsu no Tiara to Gelato (秘密のティアラとジェラート) will be released on October 12.
The theme of the music video was inspired by the 1953 movie Roman Holiday starring Audrey Hepburn. The members of the idol group are on vacation near the Piazza di Spagna in Rome, Italy, like in the film.
Houkago Princess member Yamaguchi Miran wrote the lyrics of the coupling song Forza! Ole!.
