Mr. Fullswing (stylized as Mr.FULLSWING), also known as MisuFuru (ミスフル), is a Japanese baseball-themed manga series written and illustrated by Shinya Suzuki. It was serialized in Shueisha's Weekly Shōnen Jump magazine from May 2001 to May 2006, with its chapters collected in 24 tankōbon volumes. The series follows Amakuni Saruno, a loser at attracting girls, perverted and prone to getting into trouble, yet he has great strength of heart and body. He is accompanied by Kengo Sawamatsu, and the pair work together in order to fulfill Saruno's dream: dating Nagi Torii, Junishi baseball team manager. Determined to win Nagi's heart, Saruno enters the Junishi baseball club, despite being a complete amateur at baseball, only to find many obstacles, as well as new friends and rivals awaiting him there.
Amakuni Saruno is a 15-year-old student of Junishi High School. As a teenage boy, he desperately tries to find a girlfriend. Being fed up with seeing all the girls fall in love with high school athletes, he decides to join a sports-club himself. He starts looking around at the different sports clubs with the guidance of his friend, Kengo Sawamatsu. They go to check out the weight lifting club (of which there is only one member, a large, frighteningly buff guy), only for Saruno to see a girl that he assumes to be the manager of the club and show off for her. After sufficiently hurting himself, he helps the girl, Nagi Torii, carry some weights off somewhere and while talking to her finds out that she is actually a manager for the baseball club, not the weight lifting club. Saruno decides to join the baseball club so he can win the heart of Torii.
In joining the club, Saruno finds himself to be very weak compared to other tryouts, surpassing others only in hitting ball. He barely manages to get into last test phase, 5-innings training.He, with other low-ranked entrees, has to survive 5-innings against team composed of high-ranked entrees. In this game, he met Chounosuke Nezu (pitcher), Mei Inukai (pitcher), Pino Tomaru (second), Aoi Shiba (shortstop), Shinji Tatsuragawa (catcher), that forms core of baseball team. In process, Saruno's team manages to pass the test with Saruno breaking the Muranaka record, hitting the school clock. After the entry test, Saruno again finds himself underpowered against seniors of Junishi baseball club.
