The Demon Swordswoman

Equestria
After Discord's defeat

"Fan out, everypony! Find the remaining creatures!"

That's what the Captain of the Royal Guard ordered to her troops as they scoured the nearby forest. Shortly after Discord's defeat at the hooves of the Alicorn sisters, they took charge of leading Equestria from then on, and any of Discord's abominable creatures that were left behind were to be slain immediately on sight. When an hour has passed, the guards reported back with the destruction of the remaining monsters, until a grunt came up to the new princesses all frantic like.

"Your Highnesses! Come quick! There's a creature I've never seen before, but it doesn't look like one of Discord's abominations!"

The princesses and the Royal Guard followed the grunt to find a bipedal female with black hair, black and red clothing, and a katana in her hand, all the while she is asleep.

"Strange creature, indeed." The Captain said, then turned to the princesses, "Should we slay it?"

Celestia walked up to the female and use her hoof to move her head from side to side, examining her appearance. She removed her hoof from her face and backed up.

"...Get her to the infirmary, restrain her as well, in case she is a threat."

The guards did as she said and took her to the medical wing of the castle while roping her arms to the bed.

Three Hours Later...

I stirred awake and took notice of my surroundings; I was in a hospital of some sort and for some reason, ropes were tied on my arms and onto the bed, holding me down. I tried to struggle, to get my restraints off me, but a voice stopped me.

"Be still, young one." A giant pony stepped out of the shadows, she was white with purple eyes and an ethereal like mane and tail, wearing gold regalia around her neck and on her hooves, "I would like to ask you some questions."

There was no mistake.

I'm in My Little Pony: Friendship is Magic.

Yeah, I'm a brony, got a problem?

Anyway, I was still trying to grasp my situation, what did that merchant do?

"First, what is your name, little girl?"

"Girl?" I asked, and immediately noticed the change in my voice and knew who's it was, "...Mirror."

"What?"

"I need a mirror."

Celestia was surprised, but levitated one in front of me.

Then I saw it.

I heard the rumors of people disappearing from conventions, but I didn't believe them until now.

Whatever that merchant did...

I somehow became Akame.

I knew that I still didn't answer Celestia, so I have the name I should stick with.

"...Akame."

"Huh?"

"My name...is Akame."

"Well, it is very nice to meet you, Akame. Forgive me for being blunt, but...what exactly are you?"

"Human."

"Human...I must say, I've never heard of that species before."

"I didn't think you would."

"Hmm...does the name, 'Discord', ring a bell?"

Of course it does, but I couldn't tell her that, "...Not really, no."

"I see."

Just then, someone barged in the room, "Your Highness! Our Unicorns have discovered something within the sword the creature had! There's traces of an unknown poison embedded in the blade! We tested it on one of Discord's creatures and it died in seconds!"

Celestia gasped in shock at this news and turned to me, "How can you have such a weapon at your disposal, Akame?"

I hesitated, but answered, "It's called an Imperial Arms."

"Imperial Arms?"

"One of many. My sword, Murasame, is known as the 'One Hit Kill Sword' due to the poison inside it. It only takes one strike, once the blade enters my opponent's flesh, the poison courses through the body and inflicts the heart. There is no cure for the poison."

The two were rendered silent by my explanation, but the armored pony recovered quickly and drew his spear.

"I knew this thing was dangerous! I'll slay it while it's restrained!"

With a battle cry, she charged forward, ready to end me, but I didn't even flinch. Celestia stopped the armored pony with a hoof.

"Settle down, Commander Hothead!" She ordered, then turned to me with an unreadable expression, "She's powerless without her sword, and she can't move at the present moment, so right now, she poses no threat to us."

"I don't intend to hurt anyone here." I said.

"Right now, we can't trust you, so you'll have to stay with us, and your sword shall remain in our custody until further notice." Celestia turned back to Commander Hothead, "Leave us. I wish to speak to Akame alone."

"But, Your Highness!" Celestia's glare shut her up and she sighed, "Very well." Hothead gave me a glare of her own as she left.

Celestia turned back to me, "Tell me more about these, 'Imperial Arms'."

For the next few hours, I explained, to the best of my ability, what the Imperial Arms are, how they're made, and what some of them do. Celestia nodded her head every now and again, letting me know she understands my explanation. After I was done, Celestia stood up, lit her horn, and released my bindings.

"If what you say is true, then we will need you in the coming days. But for now, you are a Royal Guard in training. Other than me, Commander Hothead is your superior, you will listen to both of us and do what you are told."

I nod, "Understood."

"Good, now get some rest, your training begins tomorrow."

"And my Murasame?"

"Shall remain with us until you can be trusted. You will be given a new sword for the time being."

She left the hospital room and I was alone, only one thing passing through my mind.

Tomorrow's gonna be hell...
