The Labyrinth City Orario is a large city with a vast underground labyrinth, where the gods live.
They reside in the human world, not the Heaven. Because the gods' lives are too long, they get bored in heaven, so they descend to the world, seal their powers, and then choose humans, elves, or half-humans, give them blessings, guide them to form Familia and help them develop.
The city was founded by the gods and is used to entertain them, as well as being a city coveted by intelligent beings in the world. Here, anyone has the chance to become famous, to become a hero or a champion in someone else's story.
In this world without a demon king, the way to become famous is of course by competing between intelligent races. But since this world has gods, becoming famous among ordinary humans feels less classy. So, the youth of this world prefer to come to Orario to try their luck. For love, money, or power, this is where dreams can come true!
And the way to make dreams come true is to join the Familia, become an adventurer, and explore the dungeons!
Dori is one such adventurer who yearns for his dreams to come true. He grew up in the village, always listening to the stories of the youthful adventures of the old men in the village. With that dream, he came to Orario, entered the dungeon, and began his adventure.
Newly arrived in Orario, he had not yet joined any Familia, but he carried the best sword of the entire village, a gift from his grandfather. Carrying the hopes of the entire village, he boldly entered the dungeon, beginning his adventurous journey.
However, upon entering the dungeon, Dori realized that the adventure in the dungeon was nothing like what he had heard or imagined.
The old grandfathers in his village described adventurers using weapons... swords, spears, axes, or even crossbows to kill monsters, or mages destroying enemies with magic.
But when Dori stumbles upon a group of monsters, ready to become a hero and defeat the monsters, the flames that descend from the sky leave him stunned.
"RPG!!!"
With a thunderous shout of the legendary spell, firelight, rumbling, and explosive sounds constantly rang out. The monster in front of him turned to ash and vanished.
A blond-haired man, holding a strange metal weapon with a wooden handle, carrying a large backpack, and carrying a black metal tube on his shoulder, ignored the still dumbfounded Dori while holding the sword of hope of the entire village. The man went straight to the place where the monsters vanished and started picking up the magic stones that fell from the dead monsters.
If Dori was from the 21st century, or even the 20th century, he would have recognized the weapons in the man's hands. One was an AK-47, a legendary weapon on the battlefield, and the other was the RPG, The Helicopter Slayer!
This was clearly a dungeon with swords and magic, where people were supposed to use swords and magic to fight monsters. But now, a weapon appears that doesn't fit the sword and magic setting at all!
All this happened because of that blonde-haired man, a Level 1 Adventurer named Altair!
A man whose misfortune caused him to fall into the Labyrinth City Orario, the city of gods and adventurers, which originated from the Danmachi series.
Altair, who was originally just your average guy living a leisurely life while counting the days of tomorrow, was very fortunate to be able to experience the dream of millions of otaku to obtain isekai, on top of that he even obtained a system. Although the name of the system was unknown and its only function was Achievement.
When Altair arrived in the new world, the system gave him a beginner's bonus.
[Tom's Body:
Have you ever heard of Tom? That's right, the blue cat. With this skill, you'll have the same body as him. But remember, inheriting his nature also means you'll never be able to defeat an enemy named Jerry.]
"Damn, isn't this too overpowered?"
Upon seeing this skill, Altair was shocked!
Tom is a legendary comedy cartoon character, and everyone knows that characters in comedy cartoons can't die, especially Tom the Cat, who is notoriously hard to beat. This was like giving him the ability to not die in the first place!
Besides Tom's Body, Altair was also given the opportunity to change his appearance like in an RPG game when creating a character.
Thus, Altair molded himself into a man with blonde hair and blue eyes. His body was strong and slender. When compared to a certain Saber from a certain series, it couldn't be said to be similar, but it was definitely the same.
Well, he was definitely copying Saber's look. After all, this world is a fantasy world, and Saber fits perfectly into that theme. So, why not capitalize on it? However, even though his appearance had changed, his name was still Altair.
Despite gaining an immortal body, Altair still chose to be cautious in this fantasy world.
Knowing no place and still unfamiliar, Altair used his attractive new face to survive with the help of some girls. Watching anime can be fun, but the reality is not that easy. The backdrop of fantasy anime is full of dangers. This world is heaven for the strong, but hell for the weak.
After a few days of investigating, Altair finally understood the layout of this city and registered as an adventurer. Along with that registration, he gained new achievements and new skills.
You will have the wisdom and intelligence of Grey Wolf. But remember, you can never defeat a sheep.]
With this skill, Altair smiled.
And that was the reason why RPGs, AK-47s, and grenades appeared in this world of swords and magic!
