King of Hell is a technique that summons a giant demonic figure with the apparent use of interrogation. It is capable of discerning whether an individual is lying or not. When implemented on a target, a serpent-like apparition emerges from their mouth and it is consumed by the figure. If they are lying (or refuse to answer the question), their life force energy is taken and they die. If the target is telling the truth, they don't die, though they're left extremely exhausted. When the Naraka Path uses this technique, the figure possesses the Rinnegan eyes similar to how the Animal path's summons all possess the Rinnegan. The King of Hell can only be seen by the ones it's being used upon.

As a secondary ability, the King of Hell can restore the bodies of whatever it eats. When it consumed the remains of the Asura path, the Path emerged from the figure fully restored and is even wearing new Akatsuki robe (the body had discarded its previous robe). Once Naraka Path uses this technique, he needs time to recharge and possibly cannot use King of Hell at all. While the King of Hell is being used for revival purposes, it seems that others are able to see it, unlike when it is being used for interrogation purpose. However it was Naruto in Hermit Mode that was able to see it so it's possible that normal people can not, even for revival.

Trivia

 * This technique is likely based on the Japanese folk proverb that the god of hell will rip out your tongue if you lie, a tale told to children to scare them into telling the truth.
