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. Shōnen Magazine Special published a sequel, School Rumble Z, monthly from August 20, 2008 to May 20, 2009.
School Rumble's popularity has resulted in its adaption 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.
Second-year student Tsukamoto Tenma learns that her secret crush, Karasuma Oji, will be transferring to a school in America. In a last-ditch effort to reveal her love to him, she writes a long (but anonymous) love letter. When Karasuma ends up postponing his transfer for another year, Tenma realizes she has to tell him how she feels before time runs out again. But her extreme nervousness around him prompts her to try and setup all sorts of schemes to get close to him and let him know, without actually coming out and saying it. Meanwhile, unknown to Tenma, the school delinquent, Harima Kenji, has the biggest crush on her, as well as the same anxieties about being direct. Around this love triangle of clueless people are a few of Tenma's friends, and her younger (but older looking, more mature, and more popular) sister, Yakumo.
