This technique requires a great deal of talent to perform. The user applies the seal's formula to an object or a human's body, sealing a large enemy or an evil spirit within them.[1] If two Four Symbols Seal are used, a stronger seal is created; this is called the Eight Trigrams Sealing Style. If the Four Symbols Seals do not completely overlap with each other, this allows the enemy/spirit's chakra to merge with whoever they've been sealed into. This is how the Nine-Tails was sealed into the body of Naruto Uzumaki.[2]
The Four Symbols Seal is based on the fūinjutsu of Uzushiogakure's Uzumaki clan.[3] According to Killer B, it is stronger than the Iron Armour Seal used to seal the Eight-Tails within him.[4] The Four Symbols Seal is also left on the stomachs of those who perform the Dead Demon Consuming Seal.[5][6]
