Tokuisei(特異性, Literally meaning. "Singularity") is the highest conceivable state of physical, mental, and spiritual conciousness within the realm of mortality.
Singularity. Eliminating all what-if scenario's and otherwise alternate conditions, the user of this state of existence becomes just that; a singular entity. There is no longer anything akin, anything different, anything that exists outside of the users own absolute reality anymore, and any and all other concepts or idea's which may suggest otherwise become ignored due to the sheer oneness that the user has achieved.
