Vampire Prison

Saito's prison is a facility in Seraph of the End that was capable of restraining vampire nobles. It was used by Urd to keep Saito imprisoned after he was captured.

Background
After Saito was found by Urd and other members of the progenitor council including Lest Karr and Ky Luc he was confined to this prison. Lest Karr confirmed that Urd made the prison and speculated that it was designed to specifically hold Saito. It had taken centuries to create, and could be formed outside with no particular location apparently being a requirement.

Appearance
A cube shaped cage had vertical bars making up the walls, where the ceiling and floor were both flat. Within this cage was situated what appeared to be a carved stone throne like chair. The armrests had iron appearing wrist restraints which were the only apparent physical means of keeping a prisoner seated. Physical imprisonment was supplemented by prisoners being bound by chains wrapped round their upper body to the backrest of the throne multiple times. The floor this chair was placed on was identical in appearance to the ceiling of the cage, with lines similar to planks of wood visible. The throne was in the middle of what resembled a shining spell circle on the floor with an inner border able to be distinguished. This visually predominant circle had other smaller ringed circles overlapping it in different places. There were two double circled rings and two single lined rings, where all five designs were connected and were of varied sizes. Around this contrivance were many large cross like implements of differing heights which seemed dependent on how deeply sunk into the ground they were. Some of them were much taller than the cage. These crosses were spread in the near area seemingly randomly, and were positioned at an angle.

Capabilities
This prison was not only able to prevent a vampire from moving, it was also able to adapt its strength to that of its prisoner. The older the vampire the more tightly the prison's chains would bind them.

Story
After the battle of Shibuya where Saito led the Hyakuya Sect in an invasion of the city to restrain the first, he experienced a defeat that Ferid and Crowley had a hand in, and was consequently apprehended then incarcerated by progenitor council members who were also present. Saito sat humming to himself in this prison with Lest Karr, Ky Luc and other vampires standing watch. While the combined physical and magical qualities of the prison were on the surface achieving their purpose of preventing Saito from moving, the ends of the armrests were crushed after he gripped them suddenly. When Saito entertains the idea of killing everyone present, Lest Karr informs him he cannot since the older the vampire the more tightly that prisons's chains bind them. Saito professed he could not move an inch and found it incredible, before expressing surprise that something like this could be made. After Lest Karr states it was probably made to contain Saito, and took centuries to make he answers that Urd was the one who made it. Within this prison is where the time Saito defeated Urd in Romania is recalled.

With the possibility of Saito being executed he attempted to induce Lest Karr into freeing him, and Ky Luc commented on whether they should open it up, indicating that there was a method to unlock the prison from the outside. When the attempt to sway Lest Karr with secrets on why the first had other third progenitors join his cause but not him failed, Saito resorted to physically breaking out himself. This was done when Saito's chains ruptured out the back of the throne, and the ceiling of the cage was ripped asunder with Saito able to raise himself into the air on his chains where the prison was unable to prevent this.
