Class Photo

S1, E13: Vlad tells students that they'd better revise for the traditional class photo. Revise for a class picture???? Eizan learns that the 'photo' is in fact a test. As the camera clicks, every student has to vanish. A Ninja's first quality is secrecy, and it's out of the question for them to be 'captured' on film. Nobunaga, unfortunately, is unable to disappear. The entire class joins forces to teach him vanishing techniques in record time. Meanwhile, Daisuke can't resist showing off in front of two young girls, and brags that he can turn into a dragon. Naginata and his gang overhear, and sneeringly announce that they'll be at Shuriken soon, to 'defy the dragon'. Now our heroes have two problems to deal with!
