Haikyū!! Shōsetsuban!! (Japanese: ハイキュー! ! ショーセツバン! ! Haikyū!! Shōsetsuban!!) is a series of thirteen light novels written by Kiyoko Hoshi and based on Haikyū!! by Haruichi Furudate. The novels were released in Japan by Shueisha between June 4, 2013 and November 4, 2020. The chapters were subsquently re-released in a series of six volumes based on the "high school and season of Karasuno", between November 18, 2020 and January 18, 2021.
Instead of being a direct novelisation, the Shōsetsuban!! novels tend to focus on things that happen before, after or between events of the manga, or those events from a different characters point of view. The novels usually contain six or seven chapters, plus a bonus chapter, often based on a Director Ennoshita movie poster.
In late 2020, Haikyū!! Shōsetsuban!! was re-released as a series of six light-novels, with each once focused on a different school along with a season. Each novel also included a new bonus chapter and new illustrations from Haruichi Furudate.
