The year is 2035 and schools have been suffering from a lack of child birth which has caused many of them to close. An energetic girl named Manami Amamiya transfers to a new school where she quickly becomes the student council president and starts to bring back some vigor in the students’ lives.

The story is about a boy named, Shichiri Tasuke, a junior high school student who lives alone. His parents are constantly traveling the world. One day his father, Tarousuke, sends Tasuke a strange ring he found in China. Legend has it that if someone of pure heart should peer into the ring then a guardian from heaven would appear to protect him or her. When Tasuke inspects this object, a goddess appears from within the ring. Her name is Shugogetten Shaorin, commonly called Shao, and her destiny is to protect the person who releases her from the ring...

"I want to join the basketball team, but Jump already has Slam Dunk, and I don’t want to join the sexy commando team." With this reason, Tetsujin Shiota and Shigeo Nara have no choice but to join South Makuhari High School's baseball team. The unmotivated and ill-natured manager Miho Sakurai, as well as the gullible Koji Kanoya who was added on just to fill up a slot, make up the rest of the team in this coming-of-age story about a baseball team that doesn't play baseball at all.

The manga is a parody and critique of editors, comedians, and other works within Weekly Shonen Jump. Examples include Sakigake!! Otokojuku, Midori no Makibaō, Rurouni Kenshin, Slam Dunk, Dragon Ball, and JoJo's Bizarre Adventure.
