Kanna

Kanna (神無（かんな）, "God of Nothingness") was the first incarnation of Naraku created with the only purpose of destroying Inuyasha's sword, the powerful Tessaiga. As a "concealed incarnation" of Naraku, Kanna had no scent and no demonic aura, making her undetectable to Inuyasha's senses and was also immune to demonic aura-related effects such as the Mount Hakurei barrier.
