Orario, the Labyrinth City, is a massive metropolis with an enormous underground maze. This is the dwelling place of the gods.
It's not the heaven (Tenkai), but rather the earthly (Genkai) home of the gods. Because the gods lifespan are far too long, they became bored in the heaven. So they descended from heaven, sealed their divine powers, and chose humans, elves, or demi-humans to bestow their blessings upon. They lead them to form Familia and help them grow stronger.
This is a city founded by the gods and created to please them. It is also a city longed for by the intelligent beings of the mortal world, for here, anyone has the chance to make a name for themselves and become a hero or brave warrior spoken of by others.
In this world without a Demon King, to make a name for oneself naturally means competing among the intelligent races. But since this world has gods, gaining fame among ordinary humans seems rather tasteless compared to the realm of the gods. So the young people of this world are more willing to come to Orario to try their luck, whether for love, money, or power. This is a place where dreams can come true!
And the way to realize one's dreams is to join a god's Familia, become an adventurer, and then venture into the Dungeon!
Bell Cranel is one of these adventurers yearning to fulfill his dreams. Growing up in a village, he always listened to his grandfather stories of his youthful adventures. So, carrying his dreams, he came to Orario, entered the Dungeon, and began his own adventure.
Having just arrived in Orario, he hadn't yet joined a Familia. But carrying the bent sword from his village, given to him by his grandfather, bearing the hopes of the entire village, he resolutely charged into the Dungeon to begin his adventure.
However, after entering the Dungeon, Bell discovered that adventuring there seemed completely different from what he had heard and imagined.
The elders in the village spoke of adventurers wielding weapons - swords, spears, axes, or even bows - to slay monsters, or of mages using magic to bombard enemies.
But when Bell found a group of monsters and prepared to act as a hero by defeating them, a flash of fire descending from above him left him stunned.
"wryyyyyyyyyyy!!"
Accompanied by a roar, there was fire, thunder, and a constant cracking sound. Then, the monsters before him simply turned to ash and dissipated.
A handsome blonde man, holding a strange metal weapon with a wooden handle, carrying a huge pack on his back, and shouldering a black metal tube, ignored Bell who stood dumbfounded holding his village's hope. He walked directly to where the monsters had disappeared and began picking up the magic stones dropped by the dust monsters.
If Bell had come from Earth's 21st century, no, even the 20th century, he would certainly have recognized the weapons in this man hands: one was the battlefield rifle AK-47, and the other was the helicopter-killer RPG.
This was supposed to be a Dungeon of swords and magic, where people should use swords and magic to fight monsters. But now, weapons completely inconsistent with the sword and magic setting had appeared!
All of this stemmed from this blonde man, a Level 1 adventurer named Nathaniel!
......
Nathaniel is not from this world.
In this era of isekai trends, Nathaniel, an ordinary semi-otaku, was lucky enough to become one of the transmigrators and gained a system. The name of this system was unknown, and its specific function was only one: achievements.
When Nathaniel landed in this new world, the system gave him a newbie benefit.
[Cat Body]
Characteristic: Have you heard of 'Tom'? That's right, the blue cat. With this skill, you will have a body just like his. But be aware, inheriting his traits means you will also be unable to defeat enemies named 'Jerry', just like him.
Holy crap, starting off with immortality right away? Isn't that awesome?
When he saw this skill, Nathaniel was shocked!
Tom Cat is a legendary comedic character, and as everyone knows, the trait of cartoon comedy characters is that they're unkillable cockroaches. Especially Tom Cat, who's the ultimate cockroach among cockroaches. This basically gave Nathaniel immortality right from the start!
Besides [Cat's Body], Nathaniel had a chance to customize his appearance when creating his character, just like in an RPG game where you can customize your character looks.
So, Nathaniel directly sculpted himself into a handsome, sunny guy template: golden messy hair, emerald eyes, a tall and muscular body. Compared to the familiar Arthur Pendragon from the Nasuverse, it wasn't just similar - it was identical!
Well, he simply copied Arhur appearance. You see, Nasuverse belongs to Japanese fantasy, and Arthur appereance fits perfectly with the Japanese fantasy setting. Isn't it good to just use him as a template? But it was just the appereance, his name was still Nathaniel.
Although he had immortality right from the start, considering this was a fantasy world, Nathaniel chose to play it safe at the beginning.
Unfamiliar with his surroundings, relying on his newly acquired good looks, Nathaniel cautiously surveyed this city for a while with the help of some young girls. Watching anime always seems wonderful, but reality isn't anime. The background of any fantasy anime is extremely dangerous; this is a paradise for the strong and a nightmare for the weak.
After carefully surveying for a few days, Nathaniel finally figured out the general layout of the city and understood its basic situation. He then registered as an adventurer. With his adventurer identity registered, he also received a new achievement and gained a new skill.
[Wolf Wisdom]
Characteristic: You will possess the wisdom of the smartest wolf king on the Green Grass Plains, but because of this, you will never be able to defeat a sheep.
After obtaining this skill, Nathaniel smiled.
And so, RPGs, AK47s, and high-explosive grenades appeared in this world of swords and magic!
