After 10 years of studying two young ninja dogs that change the form, they say they are ready for field trials. They find their new owner, Mitsuese, who takes them, assuming they are just lost puppies. He gives them new names: "Hanzou" and "Hadzuki". Two ninja dogs must protect you from any other demon, but they should not allow you to know the true personalities of our new dogs. Unfortunately, Mitsieces met Hadzuki in his human form very early when he saved him from a pair of demons. Now he must keep his relationship between people and dogs apart from Mitsuce, which is not facilitated by the constant threats of demons and their growing attachment towards him. [TETHYSDUST]
