Kagerōmaru (影郎丸かげろうまる, "Shadow Perfection") was the fourth incarnation of Naraku created for killing Inuyasha, who was become more dangerous after his transformation in a full-demon. He is also the insect-like yōkai who lives inside his younger brother, Jūrōmaru.


Juromaru and Kageromaru

Jūrōmaru and Kagerōmaru.

In the manga, Kagerōmaru's first action upon birth in Naraku's bedroom was to decapitate his master. He then killed two of human retainers who blundered into the scene and dragged their bodies back into the pot the incarnation was birthed from. Naraku took the chance to squeeze his heart as punishment. Unknown to both, Kagura had been watching from the shadows, annoyed decapitation won't kill Naraku.

Upon Jūrōmaru's introduction, it is obvious 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. Initially, Kagerōmaru and Jūrōmaru are able to overwhelm Inuyasha and Kōga in battle due to their unpredictable movements and abilities, with Kagerōmaru diving underground and then back above ground with astounding speed. Later on, however, Kagerōmaru is considerably slowed down by a miasma that Sango injects into the ground. Kagerōmaru is then kicked by Kōga, and finished off by Inuyasha with a Tessaiga's slash along with his brother, although the sword was too heavy.[1]


Kagerōmaru is a devious manipulator and enjoys eating other people's insides. He wants to eat Kagome, but Inuyasha and Kōga team up somewhat to try and stop him. He hides and strikes without warning.

Physical description[]

Kagerōmaru is small, with mantis-like arms and a roundworm-like body.

Powers and abilities[]

  • Keen intellect: Kagerōmaru appears to have a crafty, sinister intelligence, which he uses to his advantage over the rather hot-headed Inuyasha and Kōga. This makes him much more dangerous than his host/brother, Jūrōmaru, who is more of a puppet with limited consciousness.
  • Digging: Kagerōmaru has the ability to dig deep in the soil, and pop up out of the ground at any given time.
  • Enhanced 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.


  • Unlike Naraku's other incarnations, Kagerōmaru doesn't have a spider burn mark on his back. Moreover, he and Goshinki are the only ones to not have human forms.
  • In the anime, after Inuyasha slashed off Kagerōmaru's left claw, it was still intact in some scenes.
  • His and Jūrōmaru's seiyū would then voice Yotsume in Hanyō no Yashahime.
  • Magatsuhi's temporary human-like body, created through Naraku's flesh, resembles to Kagerōmaru.
