What it does:
It invokes the power of a spectral entity known as the Shinigami that can only be seen when it grasps one's soul. Once called upon, the Shinigami hovers behind the user and wraps its left arm with prayer beads, uttering some unintelligible chanting, and after some time a cursed seal appears on its arm. The soul of the summoner is then partially separated from the body and restrained by the Shinigami's hair as it thrusts its arm into the user's chest to grab the soul of its target. At the user's command, the Shinigami then performs the sealing by dragging the target's soul into the user whose stomach is branded with the seal's mark. However, the sealing is double-edged as the user's soul is devoured by the Shinigami along with the target's, both souls trapped for all eternity within the fiend's stomach.

It is also possible for the user to seal multiple targets through the use of shadow clones. The methods of sealing vary, one of which is  needing to get close to the users targets in order to perform the sealing, while another way is to be able to extend the Shinigami's hand to grab the users opponent

Backstory:

I'd like this to last at least five posts before dual death, mainly on the basis that when I saw it used it took for damn ever.
