An immortal ninja cursed with a vengeful war spirit is forced out of hiding to protect the last descendants of his sworn family, even if it means unleashing the monster within. Six hundred years ago, shinobi warrior Genshi Sakagura was cursed to share his soul with a mythic spirit of war—the Tengu. Now immortal, he hides in modern-day New York, living in silence and penance, praying the curse stays buried. But when an ancient cult threatens the descendants of the family he swore to protect, Genshi must take up the blade again. To save them, he risks unleashing the monster inside—and becoming the very weapon the world fears most.
