Shinkūmyō

A Shinkūmyō (, lit. Empty Existance) are Blanks that have underwent a form of transformation becoming entirely new beings. When a Blank is born, their soul splits into two seperate entities, Memories and Energy. The memories left from blanks fuse together and return to the living world in the form of "The Memory Rosary." The energy becomes a white cloaked, red headed species known as Blanks. However, in very rare occurances, using Hollowfication and Shinigamification as a Chain, the memories and energies may be chained and reunitied into a new being, known as a Shinkūmyō.

Terminology
Like how Hollows who gain Shinigami powers are given the name Arrancar, and Shinigami who gain Hollow powers are called Vizard, Shinkūmyō is the term given to both; Either a Blank who obtains Shinigami and Hollow Powers (Basically, gaining the power of a Xiāochú which is a stable side of both powers), or a Xiāochú who has grown a Blank/Hollow-like Entity within himself and can access it's power. The inner being is usually called the Inner Rosary, and is created when one attempts to supress their memories and feelings to an extent, to which they create a being within themselves. This case has never been shown, expect with the case of Seireitou and Sanagi.
