3rd person POV:

An army led by the great hero Ciri and her companions marched towards the  Demon Lord castle.

When they were met with the demon army, the fight broke out.

Ciri and her companions charged past the demons while leaving Yenefer to command the army.

Meanwhile, the Demon Lord was whistling to himself in his throne room.

Demon Lord:(whistles)

Ciri and her companions fought off a small group of demons. After defeating the demons, they were stopped from continuing by the Demon Lords right-hand demon, Orcan.

Orcan: Foolish mortals! You dare break into the great lord's castle!?

Ciri: This is the end Orcan! The Demon Lord will die today!

Orcan: Not if I have anything to say about that.

Elf: Ciri, go on ahead, we'll defeat him then meet up with you.

Ciri: Are you sure?

Brawler: Don't worry about us, we'll beat him to a pulp!

Ciri: Fine, I'm counting on you all. Don't die on me!

She rushes onward. Orcan fires a purple ball of cursed fire at Ciri. She pulls out her magic sword, a silver blade with a v-shape cross guard, and runic symbols along both sides of the blade.

She swung the blade at the purple fireball when the sword made contact with the attack, the fireball was seemingly negated and the excess magic from the attack was absorbed by the sword.

Orcan was stopped from attacking her again when her companions attacked him allowing Ciri to escape.

Ciri:(mind) Thank you all. I won't fail!

Meanwhile with the Demon Lord.

Demon Lord:(mind) That cake was really good... But that meat... Mmmm meat~

Ciri:(mind) I have to be careful, who knows what that maniacal bastard has in store for me.

Demon Lord:(mind) Whistling is hard with demonic lips.

Ciri then sees what looks like a door to an important room.

She kicks the door open and enters the throne room where she found the Demon Lord sitting on his throne.

She takes a battle stance.

Ciri: Today you fall!

Demon Lord:...(smiles) Let's end this once and for all.

The fight to end it all then began as the Demon Lord stood up.

Ciri waited for him to attack first, which he did. He created several crimson sword constructs that flew towards the hero.

Swinging her sword masterfully around, one by one she shattered the crimson blades with her magic sword.

Using the magic her sword has absorbed, she launches a crescent wave of holy magic towards the Demon Lord who sent his own version of the attack but with his own demonic twist.

When the two attacks collided the exploded. The Demon Lord then took flight and created more crimson blades.

This time the blades began spinning with frightening speed, turning them into saws.

They flew quickly towards Ciri who barely managed to dodge the first few attacks. She was grazed by the first few that allowed the rest to surround her.

As all the blades began spinning around her, getting ready to attack her, Ciri used more of the magic that was absorbed into the sword to augment her speed and reaction time.

As the blades came flying towards her, she rapidly began shattering the blade constructs and dodging the rest that was trying to flank her.

Ciri: Do not toy with me!

She shouted at him while turning to face him. When she turned around, she saw the Demon Lord right in front of her with a large crimson sword in hand ready to strike at her.

She jumped to the side to avoid the overhead slash, but while she was in the air, he kicked her into the wall behind her.

Ciri immediately got up and rushed towards the Demon Lord. She swung her blade at him. He used his crimson construct to block. Ciri's sword took a moment to destroy the devil's blade due to the immense power of it. Eventually, it did, and the Demon Lord was forced to lean back to avoid getting cut.

Ciri was able to graze and damage his chest.

Demon Lord:(winces)

Ciri: Have you forgotten the sting of my blade?

Demon Lord: How it's able to damage me still eludes me... But who cares?

Ciri: You should. Maybe after you get a good taste of my blade, you'll care.

The Demon Lord rolls his eyes at the accidental innuendo. He then creates a few more blades and the battle continued.

Blades clashed and damage was done to one another.

Ciri, however, couldn't shake the feeling that he was stalling for something.

The Demon Lord noticed her getting distracted, so he smirked at her. When she saw this, her blood began to boil from anger, she believed she was falling for some kind of ingenious plan of his. So she focused all of her attention back to the fight.

Ciri: You'll pay for all you've done!

Demon Lord: Eh, I don't even remember what I've done.

Ciri: You don't even remember the horrors you've inflicted on the world? You are unforgivable!

Demon Lord: Don't judge me, for you're a hero, not a judge.

He sent several constructs towards her. Ciri raised her sword to swing at the constructs, but before she could hit them the constructs exploded knocking her back.

Her sword absorbed enough of the explosion to make it none fatal but Ciri was knocked back along with having the air knocked out of her.

Demon Lord: I can't wait any longer, it's time this fight reached its climax.

He created distance between him and Ciri, then flew as high as he could. The Demon Lord then created many blade constructs that began spinning around while forming several rings that led to Ciri herself, who was breathing heavily to catch her breath.

Magic began coagulating on both the Demon Lords' hands.

Demon Lord: I've created a new spell, specifically to end this battle.

He makes several signs with his hands as Ciri got up.

He then thrusted both of his hands towards Ciri. The rings that he made, focused the spell in one direction and stopped it from leaking out.

Seeing the blast coming, she raised her sword and began blocking. The force of the blast caused her to slide back and slam into a wall, but she continued to block.

Her sword was unable to negate the attack instantly due to the sheer power of it. She began to use the magic her sword was absorbing to augment her abilities to there absolute limit.

Demon Lord: Is this all the great hero is capable of? I thought you were better than this. I guess my plans were made for someone of a higher caliber than you!

Ciri then began to try to think her way out of this situation, but her mined only flooded with memories of her friends, the good times then her mind began thinking of all the horrors caused by the demon lord.

Ciri: No!

Ciri: I can't lose... I won't!

Demon Lord:?

Ciri took a step forward with all her might.

Ciri: I am the hero who's supposed to stop you... I WILL DEFEAT YOU!

Ciri then copied the Devil Lords blade constructs and made her own purple variants while continuing to block his attack.

She then had them move behind the rings and made them form several rings like the Demon Lord had made to focus his attack.

Her rings then began spinning violently in the opposite direction of the Demon Lords rings.

Demon Lord:(small smirk)

The Demon Lords attack began spinning in the same direction as her rings. The magic began moving towards the Demon Lord.

Demon Lord: What are you doing!?

With all of her strength, she pushed the attack back towards the Demon Lord.

Ciri: RRRRAAAAGGGGGGHHHHH!!

Demon Lord: THIS CAN'T POSSIBLY BE HAPPENING! NOOOOOOOO!

The attack swallowed the Demon Lord and with a large explosion that blew the ceiling off of the throne room, the Demon Lord was gone.

Ciri fell to her knees due to exhaustion.

Ciri:(smiles) It's over... It's finally over...

(Weeks later)

In the middle of a forest in the Vaderton kingdom, a young man with brown hair, that looked extremely young for his age was lying unconscious in a circle of burnt ground.

The young man suddenly opens his eyes to the bright evening, inhaling suddenly as if he had just poked his head out of water.

He looked around. The smell of pine filling the air.

He rose up into a sitting position. He looked around then to his body, a smile growing slowly on his lips.

Young man: Legs... Two.

He touches his lower back.

Young man: Tails... None.

He looks at his arm and hands.

Young man:(smiles) No scales... Or clothes...

Young man: I've come prepared!

He gets up, looks at a tree with an x on it. He then shoves some dirt off from under it and finds a box with clothes. He puts them on.

Young man:(sigh of relief) I'm Demon Lord no more.

He then turns around to see an old man leaning against a tree.

Old man: What's up kiddo?

Ex Demon Lord: AAAAAAHHHHH!

The now Ex Demon Lord throws the box that contained his clothes at the old man.
