Tōtōsai

Totosai (&#20992;&#12293;&#25998;) is the old Youkai Swordsmith who resides inside a volcano crater. He has the abilities to work with fire and minerals from the earth and created the Tenseiga, the sword of Sesshomaru (Sessh&#333;maru), and the Tessaiga, InuYasha's sword from their father, the Great Dog Demon Lord. While it is clear from conversations with Myoga (the flea) that the Tessaiga was made from one of the Father's fangs, we have no insight into the origins of the Tenseiga. However in the manga Tenseiga is relieved to be unnecessary part of Tessaiga that Inu no Taishou had cast away as another sword.

In one episode, the Tessaiga is broken in battle and Totosai has to repair it. He knows the techniques of which both swords are capable; and he appears rather disappointed that it takes InuYasha so long to realize and control them.

He also has the ability to breathe fire and has a long traditional Japanese blacksmithing hammer he uses to forge swords and other weapons. He can also wield this hammer like a weapon, striking the ground so hard he can split the earth and bring molten lava to the surface. This fire is only used seldomly throughout the series, and mainly it's used to warn off danger (i.e Sesshomaru), or to create a barrier.

Totosai, much like Myoga (My&#333;ga), is a cowardly old man. He often seems absent minded and will appear to abruptly forget what is happening, much to InuYasha's annoyance.

Totosai owns and wears only a single raggedy Kimono and obi.

He rides on a 3-eyed ox y&#333;kai named Mo-Mo (&#29467;&#12293; M&#333;-M&#333;) which appears to be virtually impervious to various attacks, as the group periodically takes shelter behind it during battles.
