Introduced in Volume 1 during their training match, Uther showcased the basic form of this, knocking out all three of Jin, Lucas and Albedo and then tanking both Akemi's holy lightning and spirit flames and Alphonse's Satana bomb, walking away from the attack with only minor injuries.

According to Mordred, several famous killers and warriors throughout his have been able to perfect this technique, such as Oda Nobunaga, the Master at Sociopathy, and Jack za ripper, the Psychopathy.
