Why do I hear boss music?

Bonjour guys. I'm running, because I heard WREY loud roar, so taking into account the fact that my stats were increased, and how loud this roar was, I doubt that the enemy will be weaker than me. Also i don't knew why these quest is called that way. (Who can be familiar to me? A haven't met any humans in these life). Anyway

You are probably wondering what did I bought. Well, I bought 1 X2 stats pill, 3 potions of heal, 3 potions of mana, 1 blink scroll x 3, and another surprise tool which will help me later.

[{3rd person POV}]

This was a good day. As i like to say: birds are singing, flowers are blooming (flowers... in a f@#king desert), but this day wasn't good fore soldiers, who were ordered to conduct their queen and prince. The road was long and hard, but this is not the most difficult part of the journey, they were attacked by a demonic beast in the middle of the forest. The demon was 16.4 feet tall, and his entire huge body was covered with muscles. Soldiers tried to fight back, but the demon was too strong.

- BWRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA (demon)

- Retreat,, this demon is too strong (press)

- We have no chances (F)

- We will die (to)

And now, when the soldiers had already lost hope of victory, a nine-year-old girl suddenly came out of the forest. She was dressed in the traditional clothes of this country, and in her hands she had a sword.

- Girl, RUN! It's not a place for games! This demon will kill you! (pay)

The girl did not say anything, and sharply attacked the demon, , which immediately caught fire.

- BWRAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!! (demon)

- Impossible, how can this girl damage this demon? (respect)

Maybe she managed to hurt the demon, it only made him angry. He began to beat his chest and roar angrily. Even an idiot would understand that he is angry, and now he will attack even more fiercely. However, the girl stood still, not saying a word.

- RAWRRRR!

Suddenly, the demon hit the ground with his hands, raising dust and scattering all the brave warriors around. The demon thought that he killed everyone, and now noone can't stop him, but suddenly he felt pain in his knees. He looked down and saw that someone had cut off his legs. That was this girl. She somehow managed to survive his strongest attack, and he was werry angry about that. The real buttle starts now!!!

(first time trying to write the battle scene)

Demon started running on his hands, and trying to smash our Uanna, but she dodged all of his attacks and then started to counterattack. Her attacks were weaker than demon's, but that demon can't even hit her. Uanna's attacks were like a strange dance, and demon's attacks looked like a fury of nature. both of them doing their best in this battle. Noone of them haven't wanted to lose. Demon tried to ram our heroine, but suddenly before demon's attack reached her body, Uanna jumped, and started using her skills. Uanna jumped even higher using her second jump and then she used her sword technique. Her sword started burning with fire, and her body was covered by yellow lightnings. She also used her third fump to change the direction, and cut demon's head. Unfortunately, demon dodged her attack, and started his counterattack. What demon didn't expect, is that this girl won't retreat, like she done this before. She started attacking again, and she had speeded up because of her fire skill. She began to make dashes next to him and put a lot of wounds on his body. That demon can't even notice her, and she slowly killing him. Demon had enough, he punched the ground even harder, and knocked her away, and when she lays on the ground he started quickly approaching her, but when he was wery close to her, she smiled. Suddenly she grabbed his hand and used it as a support for a jump, then after this jump she used all her additional jumps, and pulled beautiful bow out of her inventory. This bow was a B+ rank nobel phantasm. This bow's secret ability was that if you use other phantasms as arrows, they receive additional damage from the solar, wind and fire elements, but even if you use ordinary arrows, this bow can shoot at a speed of 1523 kilometers per hour . She took out a spear from her inventory and used it as an arrow for this bow. This spear were also a nobel phantasm, but it had C+ rank. She quickly pulled the string of her bow and fired. She quickly pulled the string of her bow and fired. The shot pierced through the demon's body, making a huge hole in the place where the head was, and seriously damaging the demon's torso. The demon was defeated.
