(Before everyone gets too excited)
This is only a drama special, so there's only one episode (about an hour)
------
Short plot btw,
The girls attend Shiritsu Kasumi Gakuen and the school is pretty high in terms of everything (good students, athletic ability etc).
Our main character is Mami which is played by Anai and she gets a red mark on her test (low score) and as a result has to become a cheerleader for a certain club (the tug-of-war/rope-pulling club).
Anyway Mami doesn't take it too seriously, though she cheers for them, she also laugsh during practices etc so the club says "We don't want you to cheer for us".
When Mami hears that, she gathers the new cheerleaders who are Yuka (Aika), Nozomi (Haruppi) and Saki (Natsumi)
