Eizan, Jimmy and Okuni see a mysterious Ninja tell Vlad that he's failed Evasion Techniques for Experienced Ninjas, final Exam for the correspondence course he's been following. When still a student, Vlad didn't have time to finish his exams, and the truth is he doesn't have the required teaching diploma. To his despair, all he can do now is resign! No way will Eizan and his friends let their favourite teacher quit! Kubo's subject right now happens to be 'escape tactics'... Vlad can take the course, pass the exam, and he'll be qualified to teach! But how can they help...
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.
As the School prepares to celebrate the anniversary of the town's foundation, a mysterious Ninja from Katana School makes off with Tokiro's (the city's father) famous flip-flops. According to tradition, Shuriken presents these flip-flops to the public during the commemorative parade. If Shuriken School cannot produce them, the school's entire assets will be handed over to Katana School!
