Shinobi Undercover GN VOL 01

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.
The first day of school is tough for most, but when you're an awkward ninja tasked with secretly guarding a total klutz by the name of Aoi, it's absolutely daunting! But as Yodaka soon discovers, his charge is not just a danger to herself--there are also rogue ninja assassins in the school targeting her. And it's his and the other undercover shinobi's job to save her life without blowing their covers!
