If you think about it
Epilogue being stated to be beyond the
strongest imaginable and
the author saying he cannot defeat something like the epilogue
Means that any positive quality would exist in this More "Fictional layer". If we assume the Strongest Imaginable being is purely hypothetical (including any possible positive quality) as its theoretically possible to exceed even Nebula as she doesn't really limit the
Realm of Comparing abilities and There are beings who can hypothetically resist the Epilogue and would get their
story Closed by the Epilogue as they are purely fictional incomparison to it
Its similar to The Author is writing on a piece of paper and he can include any combination of words and yet...
its still remains as nothing more then words on a piece of paper while the Epilogue is outside it. Viewing Reality as
nothing more then a Book (Which funnily enough is something
Sirius Senpai did with the Manga... is Sirius Senpai actually the Epilogue ? Nah...)
It fits in with how No One
knows about the Epilogue despite 4th wall breaks or gags and
No Adjective can be used for the Epilogue as its entirely outside their fictional setting
Even Vernal herself is
implied to not know about the Epilogue... meaning she may also be a fictional character in this analogy while the Epilogue is the Reader and perhaps more distinct from it ?
The Prologue which can make any
scenario possible even if it is impossible... maybe the "Writer" in this context ? But dunno... it seems abit more consistent with the Writer Analogy I used earlier as only the Writer can create
impossible scenarios... since from an analogy Point of View.. Fiction can be whatever they want... but they are still only manipulating a Fictional Framework while Epilogue is already outside that Framework
Kinda Neat I guess
