Totosai

As a legendary blacksmith and longtime companion to InuYasha's father, this elderly master is the brilliant creator of both the Tessaiga and the Tenseiga. Though he seldom emerges from seclusion, he appears during critical moments to mend broken blades or mentor InuYasha on unlocking his sword's true potential. This fire-breathing craftsman travels atop a massive, three-eyed flying ox and utilizes a colossal forging hammer to maintain his mystical weaponry.
