The New Containment Vessel is a box designed for sealing spirits. It was presented by Asahina during a critical situation involving a possessing spirit. This vessel is capable of containing a powerful spirit that had been bound using alien magic. It became necessary after the previous vessel, which had held the spirit, was confirmed to be empty.
During the events, a ritual was performed to expel the spirit from its host and seal it within the New Containment Vessel. Asahina commenced the sealing ritual after the spirit, identified as an Ifrit, was forcibly separated from the host. The sealing process was completed successfully, and immense spiritual power was sensed radiating from the sealed box, indicating its significance and the potency of the spirit contained within.
