Summoned to Another World, but as the Final Boss [ONGOING]

(12.) Almost the Start.

    2 Years later...

    It's the final stretch. Just next year, after Alis turns thirteen — she will be entering Evelias Magic Institute and the plot of the game will begin officially. I've had over 12 years to prepare now for the beginning of the games main story, as well as prepare to prevent any events that connect to my death after the games main story begins, so you would think that I would be confident - right?

Well... Not quite. Even with 12 Years of preparation for the main story to begin, as well as all the precautions I have taken to prevent the ending - such as taking and claiming the Sacred Blade as mine and then even trying to guide the protagonist onto a different path from which they were going to walk when the main story of the game began, I was still extremely nervous and skeptical whether or not my preparations were actually enough. After all, you never know what may happen...

Maybe a sudden oversight on my side can cause the story to escalate and lead to my death, or even just the Gods interfere to try and set the story back onto the right path.... If that's even possible.

Point is — I was paranoid, despite the 12 years now that I have had to prepare for the main story to begin. After all, the final act of the game was... Well, technically 5 years away as of now, however the moment the main story starts, there will only 4 years remain for me to try and prevent the final act from turning out the way it did in the game and in case I fail to prevent it, prepare myself to face the protagonist and kill them in a fight.
I know, I know — How could I just come up with a backup plan that involved killing the protagonist should I fail to prevent the Final Act of going out the way it did in the game?

Am I not being all friendly with the protagonist right now as they're growing up? Well, yeah, but you have to consider this — It's either I kill them, should the need come up, and humanity loses the only individual worthy of the Sacred Blade of Hope.

Or I get killed and a massive calamity is launched throughout the world to wreak havoc upon it, simply because my power was released into the world. With that context —
What other choice do I have should the final act play out the same as it does in the game? I don't exactly want to let this world plunge into chaos just because I died....

Well... Whatever. For now — I should focus on continuing to search answers for a question that has been bugging me for a while.

I was inside the Demon Castles library, looking through the books in here using my magic to quickly move them around via levitation. Each book I was looking through was mainly ones focused on theories of magic, history and even the theories of how the world came to be. All books that the Demon Army had stolen either from Inara after it got invaded or were personally written by the most genius mind in the Demon Castle — right after the Demon King of course.

The most genius mind in the Demon Castle was actually also one of the 7 closest subordinates that the demon king has — her name is Kaila and her title within the ranks of the demon is 'The Strategic Hive mind'. She was weak when it came to physical power, however her magical abilities were extraordinary.

During the game, it was a nightmare to dodge all her magic attacks as they were basically random and unpredictable — which didn't make her the hardest persay, but definitely made her one of the most difficult bosses to take down in the game.

As I was flipping through the different books, I kept moving through the library, with books just flying behind me and all over the place as I kept on searching and searching for a book that could possibly give me an answer to my burning question. Just — one burning question.
How is any of this even possible?

I know, dumb to ask that 12 years after I got transported into the body of a tyrant with in a world which had a fantasy setting — but it was a question I had been clinging onto. It is also one of the main reasons I had been spending most of my time at the Demon Castle inside the library. Well, that and the fact that I was researching and creating new spells in the library, but that's besides the point. What's important is that this library had a bright and basically clear detailed record of this worlds entire history and all of its functions, which meant that it would be the best place to search for an answer to a... Well — strange question such as the one I had in the back of my mind this entire time while living in this world for the past 12 years.
