Kaguya Hōraisan (Touhou Project) attained complete and absolute immortality after drinking the Hōrai Elixir, her existence becoming utterly independent of even the concept of reality.
Possess "true" immortality.
- "We conceive of immortality as having a beginning, but no end; but we conceive of eternity as having neither beginning nor end. Hence it is proper to speak of eternity as the attribute of God, but of immortality as the attribute of man."
- ― HORACE MANN, Thoughts
- "Time... Time flows by us like water. The ages pass until we are weary, so weary of life. Everything we create is destroyed, the lands we love are upturned. Mortal man may pass beyond this world, even if they do not know what lies there, but the elves... the elves must stay. You are about to face something, Ancanar, that may require stronger faith then you know have. Death... death is a gift."
- ― Finlome (Ancanar)

Any injuries the user suffers immediately heal, even if the user's body is disintegrated or blown up or completely deleted, even if the user is completely destroyed to the sub-atomic level, they will still return to life. Alternatively, some users are absolutely immune to all harm, nor can they die of any natural causes.
The user's existence and soul become completely free and independent of even the concept of reality, making them unbound to the subjects of life, death and manipulations. Also, the power cannot be removed, rendered truly perfect and absolute.
