Dude, I would totally have joined an "Amusement Club" in high school. That sounds...amusing. And fun.
And that is the central theme behind the latest manga-to-anime announcement. Yuruyuri revolves around the four female members of the Amusement Club in their high school, in what used to be the tea ceremony club at the school.
The title is, as you may suspect from the title, yuri-themed-- it runs in Comic Yuri Hime S, and was created by well-known yuri mangaka Namori.
