简介：John Peter Macallister, a distinguished Korean veteran, concluded his service and embarked on a new life in Japan. There, he delved into the profound art of Ninjitsu and rose to become a master Ninja. Three decades later, an unexpected revelation came to light: he had a daughter. Motivated by this discovery, he set off on a quest to locate her. Yet, the path ahead was fraught with peril, as he was bound by a solemn vow within the sect he belonged to—a vow that now rendered him a target for elimination. Despite this, he managed to break free from his constraints and, upon reaching the United States, encountered Max Keller, a nomadic soul with a knack for becoming entangled in the lives of others, offering his aid whenever possible. The two men forged a bond, with Max aiding Macallister in his pursuit of his daughter and Macallister, in turn, imparting the ancient wisdom of the Ninja to him. Concurrently, they faced the relentless pursuit of Okasa, one of Macallister's former students, now a sworn enemy determined to fulfill his vow of extermination.
