Taro was just a fisherman's son... but then his father was murdered and he was forced to become a Blood Ninja, fated to live by night, doomed to live on the blood of others. But he has had his revenge. He has killed Lord Oda, the warlord who had his father assassinated.

But Lord Oda is not quiet in his grave. He has found a way to reach beyond death and Taro and his friends soon find themselves facing samurai armies, a deadly enemy from the past and strange ghostly creatures who suck life from the living.

Dangerously weakened, Taro, must recover the one object that Lord Oda was desperate to find before he died: the Buddha Ball, the source of limitless power. But if Taro is to complete his perilous quest - to save himself, his friends, his mother, and the girl he loves - he must go to hell and back and face his arch enemy once again. For Lord Oda has returned - as a Blood Ninja.
