The words in the cartoon are 5 17, 5 18. When Sesshomaru is angry with his father's decision again, he goes to duel with Inuyasha to see if Inuyasha can knock out his teeth. As a result ... the owner of the broken tooth must be Inuyasha ... Inuyasha opened the door of the underworld with the ghost broken moon (the stunt of Sesshomaru) and escaped with Sesshomaru. (I feel that Sasha originally wanted to give this trick to dogs. )

At that moment, it is said that when Sesshomaru began to give up his obsession with broken teeth, the knife that was already in his heart would appear, and he had become an independent monster. When his tooth was broken, his arm began to regenerate.
