Naraka Path

The grants the user two main abilities: interrogation and restoration, by using the King of Hell. Pain channelled the power of the Naraka Path through the body of a priest.

The Naraka Path ability makes heavy use of the King of Hell. The King of Hell is a large head which sprouts out of the ground surrounded by purple flames. It also possesses the Rinnegan as well as the shared field of vision along with the other summons. The King of Hell could fulfil two purposes: interrogation and restoration.

To interrogate, the Naraka Path need only catch hold of a person, causing the King of Hell to appear before them. With the victim seemingly paralysed, the Naraka Path begins questioning them. After answers are given, the King of Hell will unzip its mouth to release tendril-like arms and would draw out an apparition of the victim's life force energy in the form of an enlarged tongue. The King of Hell would then proceed to pass its judgement. If the person was lying or refused to answer the questions, the King of Hell would remove their tongue and consume it, apparently killing them. However, if they told the truth, they would be spared, although left extremely exhausted.

The second ability the Naraka Path possessed is the ability to repair any damage. To do so the Naraka Path has the King of Hell ingest the damaged body with its tendril-like arms into its mouth, then, after some time, the destroyed body will emerge from its mouth, completely rejuvenated. It did this for example to the Asura Path after it was destroyed by Chōji and Chōza Akimichi. With its restorative abilities, the Naraka Path can easily be regarded as the most valuable body if the Six Paths of Pain is being used through six different bodies. The Naraka Path however, seems to only be able to restore one body at a time as the Asura Path wasn't repaired when the Preta Path was.

Kabuto Yakushi stated that a Naraka Path user can transport bodies and souls using the King of Hell.

Influences

 * Naraka (Sanskrit: नरक) is the Sanskrit word for the underworld. In Hinduism it is a place where souls are sent for the expiation of their sins. Yama is the lord of Justice, the King of Hell, he puts living beings after death for appropriate punishment, for example, in boiling oil, if you lie to him, he will rip out your tongue. After the period of punishment is complete, they are reborn on earth in human or animal bodies.
 * In Buddhism, the Naraka realm, or "hell realm", is a plane of rebirth, based on Karma (actions of body, speech, and mind) built up in a previous life or lives. There are various Naraka, each containing beings that are tormented until their Karma has achieved its full and satisfactory results. The beings can then be reborn into a higher plane.
 * The Naraka are superficially similar to the Christian hell or purgatory, although there are many significant differences.
