Saga of Twilight:Calin ga Kill!

Chapter 1

mozying along down a highway of the countryside, in the imperial year 1024, being pulled by a horse with a man driving it and a man walking alongside it, is an ordinary carriage, the specifics of the carriage are unknown and unimportant on this sunny day

That is until suddenly, bursting from the ground right in front of the carriage is a beast the size of a building, its body seemingly covered in natural armor, with long whiskers on its face and arms twice the size of tree trunks, its emergence knocks over the carriage, freeing the horse to run away with the drive barely having the chance to jump out

Man 1:EARTH DRAGON!
Man 2:I didn't know they came out in highways like these!
Man 1:Run!

The two men immediately start running for their lives, but in spite of its great size, or perhaps because of it, the earth dragon is not slow and its arm is long enough to reach out and crush at least one of the men flat in moments

Or at least it would have if said arm wasn't quickly and forcibly removed from its body, hitting the ground just behind it as the monster screeches in pain as a boy lands a short distance away, with his hair split down the middle being both black and white, his eyes being a heterochromatic red left and gold right, wearing a black coat over a white jacket over a shirt split down the middle and matching his eyes, wielding a blade that seems almost out of place in his hand for how ordinary it is

???:that's supposed to be some kind of dragon? Man, real low standards for that kind of a title

The Earth dragon roars as it turns to him and lashes out with its remaining arm

???:Yeah no

As the dragon's arm hits the ground the boy jumps at it, flipping in midair as he lands on the arm, running up it towards the dragon's head

???:Say goodnight

The boy jumps, flipping over the dragon's head, using the momentum to bring his sword down on it as he passes, cutting it straight down the middle and splitting its head right down the middle, the boy and the dragon both hit the ground, one alive, one dead, the two men are amazed as they approach and become excited

Man 1:A...Amazing!
Man 2:That was amazing young boy! You actually defeated a Danger beast single-handedly!
???:Hm? Oh that was no problem at all, the name's Calin by the way, Calin Blade, I was just heading on  my way to the capital
Man 1:...So you want to make it big in the capital?
Calin:Well yeah, make it there, get rich and famous, send money back to the village, mission accomplished

The two men look at each other for a moment as if contemplating how much to say

Man 2:...The imperial capital isn't the dreamy place you think, monsters live there, far more vicious that this earth dragon
Calin:Hm? I don't remember hearing anything about danger beasts in the capital?
Man 2:It's people, not everybody, but people with the hearts of monsters, there's plenty like that there
Calin:Ah, I see, monsters in human skin huh, dealt with enough of those before (Turns around and starts walking) Thanks for the heads up though

Some time later Calin eventually reaches the entrance to the Capital and is looking around like a tourist

Calin:Man it's been a while since I've seen such big buildings, well either way now I gotta find the barracks so I can start making money

A nearby woman having a drink takes note of him due to the sheer "new to town" energy he has as he wanders off, eventually finding said barracks and waiting in line to apply, soon getting to the front of the line

Receptionist:Oh, you're an applicant then, fill out this form then bring it back
Calin:I'd start as a foot soldier?
Receptionist:Isn't that obvious? they're also usually sent to remote regions
Calin:I don't have time to slowly climb the ranks, I need you to call somebody to test my skills, I'll show you I deserve at least a captain rank
