Nobody is really interested in this from the looks of it.
I still think Shiro has this though for reasons i listed above, coupled with some more info.
Her power is bringing phenomena to an end, all beings and things have an end, she brings it. This end can basically take whatever form she wants, ie she can end an aspect of a thing or person, such as their souls or memories or even something like an explosion.
Her incomplete version using the ability seemingly is either so fast it just leaves the results, or is some sort of causeless ability, idk which. You don't know when the ability is activated, nor understand it, only thing you can see or know is just the results. Looking at it, Alice is basically this person with a supercomputer brain that can analyze things she finds for the first time, yet has no clue about The Epilogue, despite it being used in front of her, wonder what i should list that as.
The Epilogue is already active in her complete form, bypasses resistances, people who are basically almost all knowing, came up with ways to protect against it, useless, sealing it, useless, running away, useless, regenerating from being erased from existence, useless you still die, being beyond the concept of life and death, useless, manipulating fate, probability and causality to win even if there is a 0% chance to win, useless, manipulating the story to win, useless, evolving into a being who can win, useless etc. The end comes to all things no matter what means you use.
Anyway gonna have to figure out what to do about The Epilogue later in the next CRT. Her incomplete version has it so is it some sort of smurf hax, and should it be listed in her complete form as something separate, though in that case i don't think so, it's stated to be her essence, something that makes up her existence, separating it from her seems contradictory, and her incomplete self hasn't shown anything to indicate it scales as high as when she is complete, so don't really think much changes, besides the other additions like concept manipulation, deconstruction, FTL upgrade to a lot of ppl, and maybe a 2-A upgrade.
