HAIKYU!!: VS Failing Marks

HAIKYU!!: VS Failing Marks is a single-episode OVA that bridges the gap between the first and second seasons of the popular sports anime. This comedy-drama special follows Hinata and Kageyama as they navigate the consequences of bombing a test, only to discover their make-up exam falls on the same day as a crucial training camp. The episode balances the series' signature humor with genuine character stakes, offering fans a lighter glimpse into their favorite players' lives outside the court.

The OVA premiered at Jump Festa 2015 on November 3, 2015, before being included as a bonus with the twenty-first volume of the original manga. It's a brief but worthwhile addition for those invested in Karasuno's roster, providing both comedy relief and character development in a tight runtime. The special captures the show's blend of volleyball action and slice-of-life storytelling that made the series resonate with audiences.
