Inuyasha the Movie 3: Swords of an Honorable Ruler 2003

Plot:

The Great Demon Dog, Inuyasha and Sesshoumaru’s father, possessed three swords: Tetsusaiga, Tenseiga, and Sounga. While the first two were left to his sons, the Sounga was sealed away so that its evil would not destroy the world.

Everything changes though when Sounga breaks free from its bonds. With a burning desire to destroy the only two swords that can defeat it, Sounga seeks out one whose hatred for the Demon Dog and his sons would give it the chance to destroy the swords and their owners in one fell swoop. 

Will Inuyasha and Sesshoumaru put their differences aside to defeat Sounga, or will the Demon Dog’s bloodline come to an abrupt end?
