Toshiya Shinohara

After 700 years the sword Sounga, who belonged to the Great Dog Demon, is unleashed, tearing a rift in the barrier between the underworld and the earth and stirring the restless souls.

After seemingly defeating their common enemy, Naraku, what appears to be the near-end of their journey instead leads Inuyasha and Kagome facing against a new threat.

The past catches up with the world of Inuyasha and Kagome's present in a form they could never have anticipated.
