Kip. 20: Despicable Villain! The Mystery of Onigumo!

Kaede reveals to Inuyasha and Miroku a nearby cave, in which she and Kikyo once cared for a badly burnt thief named Onigumo. However this thief ended up lusting for Kikyo and allowed his body to be consumed by the yōkai from his desire for her, thus created who is to be known as Naraku. Naraku soon unleashes a corrupted Rouyakan upon the three, inasmuch as Inuyasha is in a weakened state. Rouyakan returns for a second encounter, with a jewel shard embedded in his head by Naraku, causing panic for the three. (Source: Wikipedia)
