Teekyuu is all about the wacky antics of four schoolgirls—Kanae Shinjou gets bored easily and often breaks the laws of physics to get what she wants; Nasuno Takamiya is incredibly rich and knows how to make things go her way; Marimo Bandou would probably get arrested from her actions like eating panties or kidnapping children; and Yuri Oshimoto, their ordinary junior, rounds out the eccentric bunch that forms the sole members of their school's tennis club.
Despite their interest in learning the sport, the older girls prefer messing around, while Yuri, being the only one who actually knows how to play and the most mature in spite of being younger, has to deal with her seniors' out of control behavior.
When these four girls come together, insanity ensues in this lightning-paced comedy about a tennis club that doesn't really play tennis.
Nora Handa is a boy who lives with Shachi Yuuri, who was adopted by his mother. With everyone supporting, the two of them grew up healthily even after their parents passed away. Shachi, who likes Nora the most, wakes him up every morning.
Nora spends his happy student life with Michi Kuroki, who is a disciplinary committee, honor student at school and childhood friend of the main character, Yuuki Asuhara, who is a gal but is very bright and can talk his worries to, and more friends at school.
One day, Nora meets a girl who calls herself Patricia at the park on the way to the school. Patricia is a queen at hell, and claims to come here to destroy the life on land. However, she is damaged heavily because she touched the life for the first time. The energy was stronger than her, so Nora needed to tend her. Patricia asked him to tell her about the mysteries of life, and he had to even explain the ero book that he found at the park...?!
