Kagerōmaru

is the fifth incarnation of Naraku, and is also the demon who lives inside his younger brother Jūrōmaru. It is seen later in the episode that Kagerōmaru is the one, and only one who seems to have control of Jūrōmaru, due to Jūrōmaru immediately slaying his "master" (Naraku's demon puppet) once his shackles were removed. Kagerōmaru is slowed due to Sango pouring a miasma into the dirt that seems to considerably slow Kagerōmaru down. Kagerōmaru is then kicked by Kōga, and finished off with Inuyasha's Kaze no Kizu.

Abilities
Digging: Kagerōmaru has the ability to dig deep in the soil, and pop up out of the ground at any given time.

Speed: Kagerōmaru, as well as his brother Jūrōmaru, have superior speed. However, Kagerōmaru's speed is arguably at least twice as fast as Jūrōmaru's.
