Karasuno has successfully defeated Tohru Oikawa and Aoba Johsai in their practice match, but the team's future doesn't look so bright. The match uncovered serious holes in Karasuno's defense, which would be fatal in a real game! What they need is a defense expert, a libero, to cover their holes for them. It turns out Karasuno does have a libero named Yu Nishinoya, but he was suspended for one week for violent behavior! And he's even shorter than Hinata!
