School Rumble (スクールランブル, Sukūru Ranburu) is a Japanese shōnen manga series written and illustrated by Jin Kobayashi. First serialized in Weekly Shōnen Magazine from October 22, 2002 to July 23, 2008, all 345 chapters were later collected in 22 tankōbon volumes by Kodansha. Magazine Special published a parallel world story, School Rumble Z, monthly from August 20, 2008 to May 20, 2009. A romance comedy centering on relationships between Japanese high school students, School Rumble focuses on a love triangle involving the series' two protagonists, Kenji Harima and Tenma Tsukamoto, and one of their classmates, Oji Karasuma. The series often discards realism in favor of comedic effect.
School Rumble's popularity has resulted in its adaptation into multiple forms of media. TV Tokyo broadcast a 26-episode anime program between October 2004 and April 2005. In December 2005, a two-part original video animation (OVA) entitled School Rumble: Extra Class was released. A second season, School Rumble: 2nd Semester, aired between April and September 2006. Finally, two more episodes, collectively entitled School Rumble: Third Semester, were bundled with the Japanese manga volumes 21 and 22. Three video games have been produced—two for the PlayStation 2 in July 2005 and July 2006, and one for the PlayStation Portable in 2005. Two light novels written by Hiroko Tokita and illustrated by Kobayashi were published in April 2004 and December 2007; four official guidebooks illustrated by Kobayashi and written by his editors have also been released.
