Hundred Demon Spectrum

It's unclear whether the witch doctor Tao Yao is good or evil. When she rings her golden bell, nothing remains of her enemies. She could be the youkai's savior, or she could be their worst nightmare. Beyond the human world is the place where youkai dwell called Taodu. Taodu's witch doctor Tao Yao only treats youkai not humans. Accompanied by the young monk Mo Ya, they travel the world in search of the Hundred Demon Book.
