Masters of Lightning Knives

A young orphan was alone in the world until he meets the master of a secret form of martial arts. To learn these otherworldly techniques, he will need to endure years of his sadistic teacher’s grueling and weird training. But why does he have to do laundry, cook meals, or play instruments to learn martial arts anyway?! If he can survive long enough (and if his massive ego doesn’t get in the way), he just might be able to wield the unstoppable lightning knives. Will he make the cut or be sliced down to size?
