Fūinjutsu: Death's Shrine

Fūinjutsu: Death's Shrine (封印術: 死の神社, Sealing Technique: Death's Shrine) is a high level that was created by the  of Uzushiogakure. A technique of the highest caliber, its knowledge survived the destruction of Uzushiogakure and has recently been taught to Ryū Uzumaki by one of the survivors of the Uzumaki clan.

This technique creates a powerful rectangular barrier around the target, with a large circular door on one side that opens only inwards, allowing individuals to enter but not to leave. Thus after the barrier is set up any number of targets can be forced into it via the opening. But what makes this technique unique is the source from where it draws the chakra to sustain the barrier. The caster of the technique only needs to supply the initial amount required to set up the barrier, after which the barrier starts draining chakra from the ones trapped within it. The more the target struggles against the barrier the faster the rate at which it drains his/her chakra. The barrier keeps on slowly draining the target for five minutes, at the end of which the gathered chakra is released as a powerful blast aimed inwards from the circular opening.

A way to counter the barrier's chakra draining effects is to forcefully shut down one's chakra system, thereby nullifying the technique's ability to drain chakra.
