Honor and Curse: Eternal #1

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, ninja warrior Genshi Sakagura vanished from history—cursed with immortality and haunted by a war-hungry spirit known as the Tengu. Now living in modern-day New York, Genshi’s centuries of silence shatter when a terrorist strike and a kidnapping tied to his ancient past force him back into battle. To reclaim his honor, he must once again unleash the curse he’s spent lifetimes trying to contain.
