The Anti-Seal (逆転印章 Anchi Shīru, "Reversal Seal") is an Unrestricted Spell Insignia that reverses the effect of Unrestricted Spells. It is usually used to defend against attacks.[1] However, Dantalion aimed to use it to counteract the effects of Tuning in Misaki City for his experiment regarding Distortion. His first attempt was thwarted by Flame Haze, but later it was used as one of the steps to create the new world Xanadu.
Background[]
During the Misago Festival, Dantalion managed to construct an incomplete Anti-Seal activating his Crystallization of Self-Research, the Illusive Birds, that were placed around Misaki City Station beforehand. The arrival of the train, Coffer of Evening Party which contained the last piece of the Insignia would start the Anti-Seal. Flame Haze were only able to realize the existence of the Anti-Seal and his plan until the very last moment by Yūji Sakai's plan and information from Crystal Altar. Dantalion's plan was thwarted after the train was incinerated by Shana just before it arrived the station.
In the events leading up to the creation of Xanadu, the Anti-Seal is once again utilized to undo the Tuning that was done by Khamsin Nbh'w, by using Yoshida Kazumi as a map to find the Tuning markers around Misaki City. The Anti-Seal strengthens the links between the Distortions that were before hidden by the Tuning, and then moves these Distortions away from each other, until the connections between them are lost, and the Distortions essentially disappear, creating voids in their place that allow Power of Existence to be poured through to the Rift Between Both Worlds. As Yūji Sakai put it, the result could be described as a "a silk cloth becoming as porous as a net".[2]
Trivia[]
- Anti-Seal is supposed to make its first appearance during "Mobilizer of Ceremonial Equipment" Arc in the anime adaptation, but was substituted with the anime-only spell, Whole Sacred Chapel. However, when the spell was activated, Khamsin at first predicted its effect to be like Anti-Seal's.
