"Impetus" (Japanese: 刺激 (しげき) Shigeki) is the one hundred and sixty-first chapter of the Haikyū!! series written and illustrated by Haruichi Furudate. It was published in the 29th issue of Weekly Shōnen Jump’s 2015 series.

Overview Edit

This chapter starts and ends within the 2nd set of Karasuno VS Shiratorizawa.

Plot Edit

Shirabu is stated to have previously done a dump-shot.

Akiteru notices something was different about Kei to which Yachi points out that Kei seems to have more passion than usual. The game continues with Ushijima doing a serve which Sawamura receives.

Throughout the game, Tanaka manages to do a block-out up against 3 blockers and the teams tie at '24' because of that. A spectator states that the 'skilled libero' (Nishinoya) was leaving the court but Hinata is switched with him and accidentally bumps into Hinata. Saeko realises that Sugawara couldn't be subbed in again and Shimada states that it is against the rules to sub the same person twice in the same set. When Tendo was about to spike the ball Hinata manages to do a one-touch thanks to Tsukishima's earlier advice and prediction when Hinata bumped into him. Kageyama later does a return dump-shot.

As the match continues, Takeda states how it is difficult for volleyball players to score points in succession and Keishin explains how the sport is moulded to allow both sides to have a chance to attack hence both teams need to be more focused upon reaching the end of a set. He also talks about the importance of how the players are also required to have a large amount of energy to snatch and gain points. Hinata once again fufills his role as a decoy and allows Tanaka to score against a 1.5 block.

The chapter ends with Shiratorizawa calling for their 2nd time-out of the 2nd set with a score of (S)25/26(K).
