He was dead. And suddenly he rose from the dead. The last of the guardians of the ancient art of Japanese ninja, the invincible warrior of Lady Luck, Semyon Stupin, nicknamed Bull Terrier. By chance he was caught and put on a chain. But is it possible to hold a hurricane, flood, or lightning on a chain? And although he suffered a lot in battles, he managed to break free and began to play by his own rules. Now he has to find out: who tried to use him for their own purposes and why? And anyone who gets in his way is doomed. Because a bull terrier can be killed, but cannot be turned into a chain dog.
