Kageromaru and Juromaru are the fourth and fifth children of Naraku. When Juromaru first appears he is shackled up and wears a mask when he fights Koga. Later when Inuyasha's gang comes along Naraku's puppet releases the shackles and removes the mask but ends up getting its head removed. Later on while they fight Kageromaru comes out of Juromaru and says that he is the one that controls Juromaru. Koga and Inuyasha then team up to fight them but with Juromaru's speed and Kageromaru's ability to dig underground it seemed impossible. Finally as Kageromaru is about to attack Inuyasha slays both of them with Tetsaiga.
