Inuyasha: Humans

His only weakness is that a hanyou loses its power during a certain time period each month; Inuyasha's time is the night of a new moon (when the moon is not visible). His hair turns black and he loses his superhuman strength, speed and defensive abilities, as well as his dog ears, claws, fangs, etc. In this form, basically all of his youkai powers are gone and he turns human; ... he returns to normal at sunrise. He prefers to keep it a secret because on that night he is vulnerable, and only his group and a few others know his secret.

Sesshomaru, Inuyasha's full demon, evil half brother is after a family inheritance, a powerful sword called the "Tetsusaiga". Meanwhile, Inuyasha is miraculously reunited with his human mother, who supposedly died long before!

Speed: While not as fast as Entei the youkai horse that served as Hakudoshi's steed, Inuyasha's speed has been shown to easily exceed that of a normal horse. He is able to cross great distances with a single jump, sometimes creating the illusion that he is flying. The Ougikaiden says he can reach the top of tall cliffs with a single leap as well. As seen in the movie canon, Inuyasha can move fast enough that he appears to regular humans as nothing more than a brief and indistinct red blur (see volleyball incident in movie 3) and can apparently move fast enough to run over water (see movie 2).

Sesshomaru returns with a demon's arm replacing the one he lost in his first battle with Inuyasha. Naraku arrives and offers Sesshomaru a new arm- a human arm that will allow him to hold the Tetsusaiga and a Shikon shard to increase his power.
