A young ninja battles the ultimate opponent—his own awkwardness!

Yodaka’s worst nightmare comes true when his job as a Public Safety ninja forces him to go to high school and even worse…talk to people! When it comes to combat, his skills are off the charts. When it comes to social interaction, he completely falls apart. But things take an unexpected turn when he discovers that talking to Aoi Mukai, the girl he’s assigned to guard, is surprisingly easy.

Squad No. 9 gets surprise backup from their formal rivals Squad No. 6 as they attempt to rescue Aoi from fugitive ninja. But even with the additional firepower, the fight turns desperate when the enemy unleashes a new ultra-powerful attack called Primal Kekkai! Just what is this new ability, and how can it be stopped?
