Premieres January 4th, 2025. The new PV is here. Check out the Crunchyroll article for additional information. Synopsis from AniList:
I, Teruaki Nakamura, transferred to a school in Okinawa and developed a crush on a girl named Kiyan-san, but I don’t understand her dialect. Higa-san is always helping me by translating the dialect. A slightly different cultural love starts on the southern island.
Some quick searching and it looks like multiple brands of sanpin-cha all use similar color schemes. So it is probably meant to depict just the Okinawa specialty more than any brand in particular.
Zombie Land Saga used to do similar things where the eye catch scenes in the middle of the show would depict them all using/eating/visiting iconic Saga Prefecture things.
weird, its so in your face and the two closest cans have their labels perfectly lined up with the shot xD
