Two legendary swords were forged from the fangs of Inuyasha’s legendary father: Tessaiga, wielded by Inuyasha, and Tenseiga, wielded by his half-brother Sesshomaru. And now a third sword Sounga appears with the power to dominate the three worlds: the heavens, the underworld, and the Earth. After 700 years Sounga is unleashed, tearing a rift in the barrier between the underworld and the Earth and stirring the restless souls.
