Sanreiikkai (三霊一界, Literally meaning: Three Souls, One World), also known as the Bounded Field of World Genesis (創世結界, Sōsei Kekkai), is a collaborative technique performed by the combined efforts of Kazuhide, Mukūrō, and Zenjou. When performed in its highest form it encloses the surroundings in a Barrier Ninjutsu that pervades both space and time for the purpose of manifesting a temporary alternate dimension. The generated space reflects various elements of each of the users core traits, with the most notable of being Bones, Darkness, and Flame.
The Winged Mirages resonate their chakra with one another before transferring it to a single individual who proceeds to create a barrier. The barrier rips the space-time continuum while expanding outwards, creating an endless void. From there on, the Winged Mirage's unified energy calls upon their personal dimension. Using their distorted barrier as an anchor.
