Episode 34

Tetsusaiga and Tenseiga is 34th episode of the InuYasha anime.

Plot
As Tōtōsai, the swordsmith who forged the Tessaiga, is introduced discussing with the old Myoga about the worthiness of Inuyasha as wielder of the sword, Jaken arrives to the deserted home the smith. It appears that Sesshomaru has commissioned a sword from Totosai, but the smith is gone to see Inuyasha.

On the road, Inuyasha is discussing with his friends, arguing that he isn't defending Kikyō for stealing the Shikon Jewel shards (which he is) because of his old love. They are interrupted by Totosai on his three-eyed cow, who challenges Inuyasha to draw his sword. They more or less get introduced. Myoga argues that Totosai can help, but Totosai thinks Inuyasha doesn't deserve to understand his sword. To test him, he ask for his protection from Sesshomaru as the latter arrives to the scene, displeased with the smith.

Inuyasha and Sesshomaru fights, and as Inuyasha seems in bad position, Sesshomaru asks Totosai if he will agree to forge him a new sword. This angers Totosai, who rejects Sesshomaru, arguing that he already forged him a very fine sword, the Tenseiga. This angers Sesshomaru in return, and Totosai takes his leave (with Inuyasha and his friends) by breathing fire hot enough to turn the earth to lava.

As Totosai and the others settle near a fire, he explains to everyone that Tenseiga is a sword of healing, which can save a hundred lives in one sweep, just as the Tessaiga can kill a hundred demons in one sweep. Meanwhile, Sesshomaru explains the same to Jaken by demonstrating on him that the Tenseiga is useless to kill. Shortly after, they attack a dragon, and Sesshomaru takes his arm after defeating him. He then goes back to Inuyasha to finish their fight. Both he and Totosai remark that Inuyasha won't win without using the "Kaze no Kizu", Tessaiga's attack.
