Bounded Field of Illusions

is a -type which allows the practitioner to enclose a space filled with phantasms of the user's own creation. Unlike most genjutsu, where the hallucinations are a construct of the victim's mind and can be successfully eliminated with standard practices of, the visions created with this technique are illusory constructs that occupy physical space. As such, dispelling the phantasms within the barrier is impossible unless an individual dismantles the bounded field or by chance possesses the rare ability to scatter spiritual energy. Furthermore, while the illusions are technically harmless as they are simply collections of various sensations operating within the confines of the barrier, this limitation only applies to victims that firmly believe them to be false. In the event that an individual assumes or takes any of the constructs as real, then the bodies of the victims will make it real. This phenomenon is due to the inherent imbalance between Yin and Yang caused by the field. More specifically, if an individual can't neutralize the realism of the Yin-aligned constructs with their own thoughts, another aspect of Yin, then their physical bodies, an aspect of Yang, will adjust to compensate for the perceived event and mirror its effects in reality.

Additionally, one can also incorporate and inflict traits of secondary illusory techniques onto those within the barrier without directly having to perceive or target them specifically. Also, while this technique can be erected as a barrier of its own, practitioners are also able to incorporate its effects into other barrier enclosures as well. This is primarily demonstrated by Tōshi Ashiya with either the Enclosing Rope Technique or Azure Yin Formation, both of which benefit greatly with the added effects of this technique.
