S01E01 Catnap Burglar
Bakufu, the famous Ninja master, literally drops out of sky (hence the hole in the school's roof) and offers to teach at Shuriken School. The Principal doesn't dare refuse, but Bakufu's fee is exorbitant.
When all the kids start acting crazy in their sleep, it threatens to get everyone expelled from Shuriken School. It's as if all the inner demons of each student are being released in their sleep. Eizan, Okuni and Jimmy must get to the bottom of this mystery ... all they have to do is not fall asleep ... stay away ... stay ... awake ... snoring. Too late!
Eizan Kaburagi and his friends experience their first year at a ninja school, where they learn only the finest forms of education there are… such as how to pass through walls, disappear into clouds of smoke and fly over rooftops.
