Kamaitachi is the giant-type Makamou, the first type without a need for Parents. Though weasel-based, Kamaitachi possessed the elements of a kerberos with its side heads holding sickles that it uses to create whirlwinds or use as weapons. A Kamaitachi appeared in Okutama to aid the Super Douji and Hime when they were fighting Hibiki, Todoroki, and Ibuki. The fight ended with the Makamou escaping with the Armed Saber. The Kamaitchi remained in Okutama, preying on humans until Ibuki stalled it long enough long enough for Hibiki and Todoroki to arrive, finally able to transform. With the Armed Saber, Hibiki assumed Soukou form and destroyed Kamaitachi with KiShin Kakusei.

A few Kamaitachi were among the Makamou at the Orochi sealing.
