Sealing Technique: Chizan

By placing the palm on the target, the user imbues a seal on their soul. The seal cannot be removed, as it is not placed on the body. Once the seal is placed, the user can trigger it at any time or distance with a single handseal. Once it is triggered, the seal acts as a portal, sending the soul, along with the body, to purgatory. Once there, the target's soul is eternally connected to the purgatory through the seal, and thus can never exit unless the user can release the seal. Even if the body can somehow exit, it will be separated from the soul, latter of which will remain in purgatory.
