I still continued to observe around professor Athena, but it seemed like the person hadn't moved.
Therefore, I decided to go to the library, this time not to read books. I just remembered, there is a secret room in the library that even the head of the academy doesn't know about.
In the original story, the protagonist accidentally discovered it.
For that, I went to the library. To be honest, I forgot what was there. When I wrote the story, I intentionally didn't show what was inside the secret room, for the mystery. Hahh, and now I don't even know what's there. Well, just knowing the place is lucky.
I arrived at the library and went to the far bookshelf. If I'm not mistaken, according to my memory it was around this bookshelf.
"Found it."
The book was a bit old and dusty, a sign that it had never been picked up. But, it wasn't the book that I was referring to, but the place that was blocked by the book. A button.
I pressed it and suddenly the bookshelf opened. According to my memory.
This room seemed to lead to the basement. I went down the stairs, and used fire magic for lighting. It's very dark here, because no one has ever come to this place. I remember roughly, if I made a story about this room, there would be a plot twist, but I forgot. Really, I want to curse this weak memory.
It feels like I'm getting deeper into this room. And I finally found the end. I was surprised, really. In front of me, there was an altar. And on that altar, there was a sword with a single eye on the blade.
"This... What sword? I don't remember this."
'Humans, it's been a long time since humans came here'
"What? Who's there?!"
Suddenly there was a voice, but it sounded like it was in my mind. I, looked at the sword. His eyes... Open.
'I, demon sword. Human, come closer'
"What do you want?"
'No, human. I just want to ask you something'
"What do you want to ask?"
'Come closer first, human'
"No, I'll answer from here. You see-I'm a very cautious person."
To be honest, I was afraid to come closer. The aura of that sword, pitch black. Demon sword, it's a sword that has its own consciousness.
'Huh, alright. Humans, is the war still going on outside?'
War?
"No. Humans and demons have had no wars for the past 100 years."
'I see, looks like I've been stuck here for a very long time.'
I guessed it. He must be an ancient demon sword. Apparently, someone sealed it here during the war of the human and demon races.
'Humans. I have a suggestion. How about you make a contract with me?'
"Contract?"
'Yes. Make a contract with me, human. Take it easy, this contract is dominated by you, so in short, I am your servant. And you can use my power as you wish.'
"You, not deceiving me?"
'No. I just want to get out, I've been alone here for so long, it's killing me.'
I still hesitated, but... There's no harm in it. After all, I didn't feel any lying intentions from words.
"Alright, let's make a contract. How do I do it?"
'You just have to touch me, and channel a little mana on your touch'
"Okay."
I approached the sword, then held it. I also channeled a little mana into my touch. Then, the sword shone, the light bright yet dark.
Then, my eyes widened in shock. A small white-haired girl was standing in front of me now, on her head were two small horns.
"With this, the contract is made. From now on, I am your servant master. Please give me a name."
The girl smiled at me.
"Wait, you're the demon sword? How did you turn into a girl?" I asked.
"This is my true form before I was sealed, master. Before that, can you give me a name?"
"Name?"
"Yes. I want a name from you, sir."
"Well, then... Rurie. Your name is Rurie."
"Rurie, I like that. Thank you, master!" She replied happily.
"Then, don't call me master. Call me Sirius."
"Okay! Sirius-sama."
This is a good thing, I didn't expect to get something like this. But, how do I carry it without anyone finding out? Having it turn into a sword isn't good either. As much as possible, I'll ask it to become a sword only when fighting.
"Rurie, can you transform into something other than a sword?"
"Of course! I can turn into a necklace, Sirius-sama. Do you want me to turn into that?" She tilted her head.
"Yes. I'll take you out now, but it will be a problem if people see your current form."
"I understand, Sirius-sama."
Then, Rurie turned into a necklace. I put it on.
"How is it, Sirius-sama?! Aren't I great?"
"Haha... Well, you're great, you're great."
Rurie was still able to communicate with me when she became a necklace, just like when she became a sword earlier she communicated telepathically.
Immediately after that, I went out of this room. Up the stairs, back to the library. I was careful not to be seen by others. And, I made it out. For now, I must return to my room first.
"Sirius-sama, when can I change?" Rurie asked, it seemed like she couldn't wait to see the outside world after so long.
"In a moment, we're heading to my room now. Please be patient, Rurie." Answer me
"Alright~~~"
Arriving at my room, Rurie instantly transformed back into a little girl. And immediately ran towards the window, looking out.
"Woaww! The outside world! The sky! Finally... I'm out! I... I... I'm out. ...."
Tears began to flow down Rurie's face, it seemed like she had been very lonely all this time.
I approached her, and stroked her head. For some reason, she feels like my sister.
"Sirius-sama... Sorry, I couldn't hold back my tears..."
"It's okay, Rurie. Cry all you want. You're great for surviving this far, now you won't be alone anymore. I'm here." I smiled, while stroking her head.
"Yes! Thank you, Sirius-sama! I'm really very lucky, because the one who found me was you." Rurie smiled.
I smiled back at her.
I can't imagine it, a girl this small being sealed into a sword in a lonely room for over a hundred years. I know the reason, it's because she's a demon. But, that's a bit... Cruel. Damn it, even though I wrote such a story setting, my heart still can't accept it when I see it firsthand like this.
From now on, I will take care of her. Penance? I don't know. I just want to take care of this innocent little girl, as long as I live.
I'll make sure she doesn't get lonely again during her lifetime.
