Azumanga Daiou The Animation

Synopsis

When Kimura is asked why he became a teacher, he replies that he like high school girls. The girls criticize his blunt comment but the boys commend Kimura for his sincerity. While changing for swimming class, breast sizes are compared among the gang. During the stretching portion of the swimming class, an infuriated Nyamo kicks a lustful Kimura out of the pool area, even though he was permitted to observe. Chiyo admits that she cannot swim but is reluctant enough to do a dog paddle. Osaka tries to learn how to float by being a corpse. Yukari interrupts the class by belly-flopping into the pool, and Kimura manages to sneak back into the pool. Yukari challenges Nyamo to a swimming relay race. Unfortunately, Yukari suffers a leg cramp halfway through the first lap, and Nyamo is left to care for her. Meanwhile, the students from Yukari's class and Nyamo's class challenge each other in their respective teacher's place. Chiyo, Tomo, Yomi, and Osaka see Kimura messing behind a bush. They soon find out that he was collecting cans and bottles for recycling purposes and charitable intentions.
