Premieres sometime in 2025. The new PV is here. Check out the Crunchyroll article for additional information. Synopsis from AniList:
Being popular isn’t easy. It’s hard to beat Saku Chitose. The most popular kid in his high school? Check. An ironclad reputation that can weather even vicious online attacks? Check. A group of friends as attractive on the outside as they are inside? Check. But when a teacher asks for his help bringing back a student who has been shut away in his room for months, Saku’s perfect world will never be the same. What is this, some kind of normie harem story…?
Not sure what significance Ramune has to this story, but all I could think about was Anchorman. Chitose is in a Ramune bottle of emotion!
