Sports anime are very common; coming of age stories are very common. Mashing them together might not seem like a good idea. "Princess Nine", however, pulls it off pretty much seamlessly by providing a large and well-defined cast of characters and pacing them in their time in the spotlight. There are other titles which mix sports and soap opera, but this one adds feminism to the mix in a non-threatening manner. The lead character, high school freshman Ryo Hayakawa, is the daughter of a student pitcher who had a blazing fastball but who died under a cloud. Inheriting her father's arm and little else, she's recruited to a prestigious girls' high school to lead a proposed all-girl baseball team whose goal is (of course) to play against the boys and get to Koshien--the high school baseball world series that is Japan's equivalent of the Final Four. Some of the characters are comic relief, and the big reveal of one of the players is held back until just before the last act. Well done, completely engrossing, and Ryo's mother is voiced by the classic Sumi Shimamoto, who also voiced Nausicaa, Princess Clarice of Cagliostro, and other anime classic characters.
