Jūrōmaru

was the fourth incarnation of Naraku. At first, he is seen in a carriage chained up, and with a retaining mask (to keep Kagerōmaru from coming forth.) Jūrōmaru is shown to be an incredibly absent-minded fellow, and an incredibly powerful one as well, being able to fend off Inuyasha, Sango, and Kōga single-handedly. Jūrōmaru is perhaps the least loyal detachment of Naraku as once he was unshackled, he proceeded to decapitate Naraku's demon puppet. Kagerōmaru is the only one who can keep Jūrōmaru under control.

Jūrōmaru's fighting style is characterized by his lust to kill - he will attack anyone in his way. When Kagerōmaru is unleashed, they manage to confuse Inuyasha and Kōga by their outstanding level of speed.

Nevertheless, he eventually gets killed by Inuyasha's Kaze no Kizu along with his older brother.

Enhanced Speed
Jūrōmaru has exhibited an astounding level of speed; surpassing even that of Kōga's. Even when shackled, he managed to catch Kōga by surprise and pin him to the ground. His movements are usually illustrated as bright beams of light.

Enhanced Strength
Along with his high level of speed, Jūrōmaru has demonstrated his high level of strength. He was able to single-handedly pin down Kōga and Inuyasha, as well as smash Sango's Hiraikotsu away during mid-attack.
