Akago

Name Information:
Akago translates to 'baby'. He is also sometimes referred to as Akanbo (baby boy).
Character Description:
Akago is the first form of the 6th detachment of Naraku who takes the form of a young baby and serves as Naraku's heart so that Naraku can be destroyed, but still regenerate (since his heart is somewhere else).
He can speak (at least until Hakudoshi detaches), and has the ability to read minds. He is able to take the evilness of a person and use it to command them.
Akago was split in half by a powerful monk (Master Shinsen) while searching for the border between hell and the living world and turned into Hakudoshi and eventually Moryomaru.
He was placed under the protection of a woman (who was tricked into thinking he was hers). Later on, this woman is killed by Kohaku, and Kanna takes Akago into hiding again.
He is given the stolen Fyoheki stone to hide him from others, and is later incorporated into Moryomaru.
