Jūrōmaru

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

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

Nevertheless, he gets killed by Inuyasha's Wind Scar along with his older brother.

Enhanced Speed
Juromaru has exhibited an astounding level of speed; surpassing even that of Koga's. Even when shackled, he managed to catch Koga 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, Juromaru has demonstrated his high level of strength. He was able to single-handedly pin down Koga and Inuyasha, as well as smash Sango's Hiraikotsu away during mid-attack.
