The girl I had been with the entire time turned out to be none other than Sara Hart, the first princess of the Hart Empire, the largest empire on the continent.
Let's imagine that this situation was common.
Let's imagine that I was truly a prisoner in the Demon King's Castle and that I suffered from amnesia.
When I first saw the girl, who was crying while clutching onto corpses, I pitied her for starving like that. However, it turned out that she was the imperial princess captured by the Demon King's army!
Let's say that I was to be rescued together with the princess.
So let's just say that the princess was going to ask them to treat me with their utmost respect.
The best expression that would fit this situation was "What a cliché."
However...
I'm a demon who's using [Change Face Magic]. If the princess tried to help me against my free will and had a high-level wizard check my brain, then I'd be dead in a matter of seconds.
Countless wizards and priests got close to the princess and immediately jumped into action. They also took some measures against me.
To my relief, I don't have any undead attributes, so the light magic priests' spells cast on me didn't cause any damage. It was fortunate that I didn't have a constitution that rejected sacred power.
Of course, if I did have such attributes, I wouldn't even be sitting here and telling you my story. If that were the case, I wouldn't have even tried to get rescued by the humans' side.
Not long after, they were treating me like a little kid.
A lot of people washed and cleaned me, wiped and tended to me. You know, it was embarrassing when I had to take a shower naked with all these men around. If there were women with me in the bath, it might be a different story.
Oh well...
It was a hot day, but the fear that I might die if I made a mistake made me overcome everything.
Let's say, for example, if a wizard cast a spell to, dispel curses on me, everything would be over. Fortunately, a large number of troops were put into searching the Demon King's Castle, and it seemed difficult for them to just take care of the princess as there were a lot of wounded and injured people among the wizard forces.
However, the question was, was Sara naturally naive, or did she somehow fall in love with me?
No, she is just trying to pay back the debt she feels like she owes me, there's no way she is in love with me, right? Right?
'Let's talk about love some other time. Now focus on what's going on, Kali.'
"Please look after this person. He's my benefactor, after all."
I bowed to the girl I had put my arm around not too long ago. Despite her lack of energy, she was constantly instructing them to take care of me first.
"N-no. It's alright, Your Highness. I'm fine. I'm healthy. Yes."
I didn't even do anything special.
"You said you lost your memory. You must have had a severe curse put on you."
"N-no, that's not it! I don't need to remember. Yeah, it's not such a big deal. Yes."
I don't want her to do anything to me.
No, I know you're a good girl and you are a princess and have responsibilities, but won't you leave me some space?
You're giving me much too much for just one piece of bread.
Eventually, I was allowed to lie in the private room next to the barracks after persuading the nursing staff and the princess. They were close to collapsing.
First of all.
I felt like I just escaped a collapsing cave only to jump into the mouth of a tiger.
[Event complete – Fall Demon named Kali]
[You have earned 100 Merit points.]
I somehow broke through the first hurdle...
And I know there will be more coming in the future.
The princess' consideration for me was persistent.
I don't know why, but after some time of resting and getting some sleep, the princess summoned me back to the barracks.
There was a huge amount of food set on a table.
"You couldn't have eaten well. Go ahead and eat."
"Oh, yes…. Yes."
I couldn't easily touch it. After all, there were too many eyes looking at me right now. She stared at me as if she knew what was going on. She nodded her head in my direction in a serious manner.
I felt like she was treating me like a child who can't even eat dinner in front of many people.
The princess turned her head toward the guards, wizards, doctor, and maid in the room.
"Get out of the room."
"But princess, it's not safe here."
"You said Demon King is dead along with all demons, so I think it's pretty much safe. Or are you hiding something from me?"
"N... it's nothing, princess."
"So get out of here."
"Okay."
Oh, I think I've seen a new side of her that I shouldn't have seen.
It feels like she's really cold, and she just changed her personality in a single moment. I should not speak rudely to her; she's a princess after all. I should be careful around her.
"Let's

I apologize for that. Here's the continuation of the corrected text:
"Let's eat quickly."
"Yes, huh? Ah, yes. Yes."
The princess grabbed the roasted chicken leg with her bare hands and began to bite into it.
"...."
It seemed like she kicked them out because she wanted to eat comfortably, or maybe she just wanted to eat with me alone.
I have to stop thinking like this. It's all my hormones' fault. I'm just a teenager in my puberty; I have to control myself. I'm a thirty-two-year-old man on the inside, and she's just maybe sixteen or seventeen. I'm ashamed of myself for thinking like this about a girl half my age.
After stopping myself from thinking like that, I asked her a question that I wanted to ask for a while.
"E-erm... Uh, won't we get sick...?"
If someone starved for so long and then ate something like this, wouldn't it cause stomach problems that could lead to death?
Do you trust the priests outside so much?
"You, too. Quickly eat."
She didn't answer my question. Oh well, there was no point in telling her that.
The meal was quite large, so I had time to sort out my thoughts while the princess munched away.
In the Prologue, the Demon King Kali died, but there was a situation that happened before that.
An all-out war between humans and the Demon Realm called the Demon World, the Demon World War.
Naturally, since there was a war going on, the hero killed the Demon King, although they ended up killing each other.
Although the reason behind the war wasn't known, it was started under the Demons' name. Demon King Kali had incredibly powerful forces and tried to make the Human Coalition surrender.
He sent spies into the Human realm to kidnap key figures of the political structure. He kidnapped politicians, kings, powerful warriors, and wizards themselves or their families to prevent them from participating in the war.
And the most important hostage was the First Princess of the Hart Empire and her mother.
Zina was the empress of the Empire; she used to have light magic as her primary spell, and that kind of spell power dealt a lot of damage to demons. So Demon King Kali kidnapped her and her daughter to exchange them for the humans' surrender in the war and use them as slaves. However, the king foiled the demon king's plan, and in the end, Kali was sent to hell by the hero of humanity.
Was it something like that...?
No. I don't think so.
Let's think about it.
It's a novel I wrote, but honestly, I couldn't remember every sentence. The story was relatively less memorable. I wrote that part the longest ago after all.
The princess, who ate in front of me with a cute face, wasn't the main character of my novel, which was a school drama romance.
To be honest, I didn't even know that her name was Sara Hart. It's not that I didn't remember it; I didn't know it in the first place. It wasn't like not remembering the name of someone passing by, but later when seeing the name of a said person written down going "Oh, right, there was someone like that."
I couldn't remember the princess' name at all.
Let's think about this some more.
What I wrote had become reality.
As a result, all the parts that I hadn't written got filled in.
So it's a butterfly effect.
This was the world I knew, and at the same time, it was a world filled with things I didn't recognize at all. Even though this is the world I thought up, it was natural that things were like this.
Therefore, there would always be events in this world happening even though I hadn't described them, and there should also be events that had already happened.
This was true.
And I never wrote anything about the first princess, who must be quite important for the main narrative. Of course, this was supposed to be just a normal slice-of-life school thing, however, the imperial family's history got mentioned slightly as well.
However, the first princess was right in front of me, and yet I had never written anything about this girl. An important character that was sure to appear on the main stage, deviating from the main narrative isn't something that should occur.
Although the princess should occupy an important role later in the story, she doesn't even appear in the future.
She is going to die soon, and I don't know what to do. Would I be able to save this girl? I knew I am not in any position to care about someone else's life.
Sara wiped the grease from the corner of her mouth as she looked at me.
The look in Sara's eyes, which had been innocent and pure until now, seemed to have suddenly turned cold.
Just when I thought that the atmosphere around her suddenly changed, Sara talked in a low voice.
"Now, listen carefully."
Sara's demeanour was more serious than before.
"Our lives are in danger."
Sara brought up what I had wanted to say before me.
And she told me it's us who's in danger, not just her. I'm telling you, it's you. You idiot.
