Fuinjei (Earth-2356)

Fuinjei are a type of Force techniques that seal objects, living beings, along with a wide variety of other things within another object. Fuinjei can also be used to restrict movement or unseal objects either from within something or someone.

The presence of a seal is marked by the appearance of formations of technique formulae or other kinds of symbols (likewise with the Summoning Technique).

A unison of barrier jenjei and fuinjei is referred to as a "Sealing Barrier". In a similar fashion to genjei, fuinjei can be undone by combining specific seals with a Fuinjei: Release command.
