Free! revolves around members of a high school boy's swimming team. Four boys—Haruka, Makoto, Nagisa and Rin—all participated in a swimming tournament shortly before graduating elementary school and later parted ways. Years later, they reunite when Rin challenges Haruka to a race and wins. When Nagisa mentions creating a swimming club, Haruka, Makoto, Nagisa and then later on Rei, form the Iwatobi High School Swimming Club.
There are only four episodes with english subs out, BUT I can totally recommend this Anime! It's funny and moving and the characters are well-elaborated!
Also there is MUCH fanservice (for girls though) and there is even a female charactere that all the Otaku-girls can empathize with (her name is Gou but she want's to be called Kou). She always fanvies about the biceps and triceps of the boys and suddenly (believe me I'm not lying ! ) all muscles of the boys are detailed and there is sparcle power everywhere!
The series has a grate kind of humor and the opening and ending are also very nice!
I'll DEFENITELEY Continue watching it and tell you guys all my thoughts about the upcoming episodes!
