Japanese voice:Takeshi Aono

Kaijinbois an evil swordsmith and the rival of Totosai. Sesshomaru calls upon him to forge the Tokijin from a fang from Goshinki (a detachment of Naraku - whose teeth were able to damage Inuyasha's sword). He is eventually taken over by the sword's evilness and destroyed during the fight with Inuyasha.

Kaijinbo was actually a former student of Totosai, but he was expelled for murdering children and using their blood to make an evil sword
