|English||Quad Burial Barrier|
This technique seals and locks away a person. Before it is invoked, four halberds are used to trap the target by their hands and legs. Once invoked, the target rises up into the sky and is then sealed in a black coffin-like box with chains wrapping around it. The four halberds then pierce the box all at once. It is seemingly able to keep a person sealed for several hundreds of years.
The only known method to break the seal is to recite a particular spell in the presence of the sealed individual.
