Absorption Soul Technique

This technique, accessed through the Human Path ability of the Rinnegan, allows the user to learn everything that the target knows simply by placing their hand on the said target. Once this is done, the target's soul is ripped from their body, killing them. Because this technique must end with the target's death, it is not suited to use on hostages who have value while alive.

Trivia

 * Although the use of this technique usually resulted in the victim's death, the person's soul could also be stored within the King of Hell.
 * While unnamed in the manga and anime, it is explicitly named in Naruto Shippūden: Ultimate Ninja Storm 3.
