Kaijinbō

is a former apprentice of Tōtōsai. Under his wing, Kaijinbō crafted weapons housing great and sinister powers. Disgusted by the results of his works, Tōtōsai banished him. Even then, he continued his work in spite of him.

Despite his short appearance in the series, his works have effected many in the long run. He was most pivotal in Sesshōmaru's quest for power, after being commissioned with the task of creating a very powerful sword, one that would rival the Tessaiga, which came in the form of Tōkijin. Created from the fangs of Naraku's third incarnation, Goshinki, the blade seethed with a terrible aura that eventually overcame Kaijinbō and took over his body. Drowning in its power, Kaijinbō attacked Inuyasha, for Tōkijin craved for the half-demon's blood. Kaijinbō is eventually struck down by Inuyasha as his entire body is obliterated in a clash. Sesshōmaru claims the sword for himself shortly after.



In the anime before his death, Kaijinbō created another powerful weapon known as the Naginata of Kenkon, a naginata weapon commissioned by the demon Hoshiyomi.
