It has been announced that Season 3 of the TV anime "Grand Blue Dreaming," based on the manga serialized in "good! Afternoon" (Kodansha), will begin airing on TOKYO MX and other channels from July 6th. Season 3 will be set overseas for the first time, and a promotional video has been released showing Iori and his friends going to Iori's family home to get their passports so they can go to the tropical island of Palau.

The PV also featured snippets of the opening theme "Natsuko" by the music unit "FUNKY MONKEY BΛBY'S (Funmon)" and the ending theme "Hadaka no Mermaid" sung by the idol group "Mameshiba no Taigun," produced by Kuro-chan of the comedy trio "Yasuda Dai Circus."
