Episode 44

Kaijinbo's Evil Sword is 44th episode of the InuYasha anime.

Plot
The episode begins in the village where Goshinki was killed by Inuyasha in his full-demon form in the previous episode. Coming out of the shadows are Rin and Jaken. After discovering the head, they ask who did it. Sesshōmaru said it was Inuyasha. He simply picks up the head, scaring Rin (though she might have faking it). Examining the fangs, Sesshōmaru can smell Tessaiga, which the fang broke it. He states that he's going to take the head somewhere. He orders Rin to stop screaming. She immediately obeys him and they follows him. What baffles Sesshōmaru is that he can smell the blood of his own and his father's.

Somewhere else in the countryside, Inuyasha is sitting with his broken Tessaiga. What he doesn't understand is how he cannot recall ever killing Goshinki. Kagome offers him a grilled fish on a stick. He thanks her at first, but Shippō yells at him for moping his broken sword. Instead, Inuyasha takes Shippō's fish and eats it. Soon a lightning bolt strikes down the ground, revealing Mō-Mō, Tōtōsai's ox, and Myōga comes to them. After finding the sword broken, his expectations were true. He tells Inuyasha to go to Tōtōsai to repair the sword. Inuyasha nods and farewells his friends.

Kaijinbō the swordsmith has completed the sword Sesshōmaru has commissioned him to make from the fang of Goshinki, former incarnation of Naraku, who broke the Tessaiga. But as Jaken comes to take possession of the sword in his master's name, Kaijinbō kills him and goes to Inuyasha to try and kill him, too, possessed by the sword's lust for revenge. Sesshōmaru finds Jaken's body, cut in half, and revives him with the Tensaiga. Jaken explains his observation that the sword, called Tōkijin, seemed to have possessed Kaijinbō.

Kaijinbō finds Inuyasha, who, as his luck may have it, is fully human. With the Tessaiga being repaired, and without his demon powers, Inuyasha is in quite a fix. However, his friends, namely Sango and Miroku, have taken on the battle, with little use. Inuyasha gets back the Tessaiga but, since he is fully human, it wont transform. The sun soon rises however, and he is now back to his old half-demon self, ready to fight.
