Infant

The  is Naraku's heart and seventh detachment. Despite his appearance, he is capable of speaking fluently. His main power is the ability to control people with the darkness in their own hearts. He attempts to control Kagome's mind by finding pain or anger within her heart, and use her abilities to find the remaining shards of the Shikon Jewel. He finds her jealousy of Inuyasha's feelings for Kikyō, but Inuyasha saves her before the Infant can control her. He is later taken by Kagura, under Naraku's orders, to temples inhabited by powerful priests. The plan was to kill the priests and read their souls as they departed from this world to the border to the world of the dead. Naraku had been told by Mimisenri that the Shikon Jewel had been taken to this border. In one such confrontation with a priest, the Infant is split in half. Both halves survived and one grew up into Hakudōshi. The other half, which contained Naraku's heart, recuperated and continued to be the Infant. For that reason, the Infant was deemed as more important than Hakudōshi, who himself was empty just like Naraku. Like Hakudōshi, the Infant is not loyal to Naraku and the two eventually betray him. However, his attempt to overthrow Naraku eventually fails and he is reabsorbed by Naraku, along with Mōryōmaru.



Abilities

 * Manipulation: Akago had the ability to search deep within a person's heart for darkness and if they didn't have enough willpower to resist him, they would be under his control.


 * Barrier Erecting: Akago was able to erect strong barriers (like his master, Naraku) to defend himself. Unlike Hakudōshi, this barrier is controlled by himself and not Naraku which the reason why Naraku has to obtain the power of Yomeiju to penetrated it.

Trivia

 * Many English-speaking fans consider the Infant's true name to be, which is how other characters refer to the Infant in the original Japanese language version. However, akago is merely the Japanese word for infant, and is not really a name.
 * Interestingly, the Infant never speaks in the series after being split in half until after Hakudōshi dies.
