Beginning

Uglix, of simple appearance, grabs the cup filled to the brim with a strange liquid from the small old wooden table.

Uglix, with a face deformed by a horrible nose, an old and wrinkled face, and a somewhat fat body, brings the metal cup to his mouth and drinks the strange liquid eagerly and hurriedly.

...

"There are no changes in my body, hehe, I should have known, it's all fake...", Uglix, of simple appearance and already tormented by his thirty years, lets out a sigh of pain, his mind analyzing the various reasons that brought him to this point.

Gradually, his mind clears with memories of past times. Formerly, as a worker in an important company in the modern world, he encountered a problem: he had reincarnated. One night it all simply ended; his body was transported to this fantasy world where various anime characters coexist in a sort of medieval life.

More specifically, this is a medieval fantasy world where various dungeons appear in different random places across several kingdoms.

These dungeons bring creatures from other worlds, including Kobolds, skeletons, necromancers, and rat kings depending on the level of the dungeon. Once a dungeon appears, the humanity have up to seven days to send qualified personnel to deal with the monsters in the dungeon. If these dungeons are not "cleared" for the first time within seven days, the monsters could come out and attack anything in their reach.

Accordingly, groups of adventurers have formed, dedicated solely to entering these dungeons and killing the monsters within, where they can obtain the hide, meat, and whatever the monster or demon has on them.

It should be noted that killing these monsters grants the killer power according to the class they chose when registering with the adventurers' guild.

For example, a mage would gain a slight increase in their magical abilities and power, a warrior would gain endurance and strength, an assassin would gain agility, and so on.

In addition to these classes, there are various professions like enchanter, who can enhance the attributes of specific armor or clothing, as well as blacksmith, alchemist, and more...

The professions are broad, and each person's adventurer card can show a different profession, ranging from herb gatherer to cook or alchemist, depending on what the person dedicates themselves to and their luck.

Now, Uglix, residing in his small hut on the outskirts of a small village under the command of a Baron in the Kamelin kingdom, is furious.

He transmigrated to this world but did not receive any system or any powerful skill besides his strange profession.

"Parasite", this profession is quite simple. It allows him to benefit and increase his stats as long as he is near a powerful character. Gradually, he can be like a parasite, feeding on the strength and magic of others until he devours the other person.

All this is fine, but, How can he do it if he doesn't have outstanding strength or magic?, Uglix is a cannon fodder adventurer who spends his time moving from one group of adventurers to another, and his "parasite" skill only activates with notable characters.

Uglix squints his eyes; this week has not been good, and he still hasn't found a group to join to go to the C-rank dungeon in the center of the small village.

Uglix looks at the empty cup before licking his lips. Mixing the blood of various low-ranking monsters with his own blood and then drinking it might not have been a good idea.

At this moment, Uglix's stomach is complaining, and he feels a great need to go to the bathroom and not come out for a couple of hours.

However,

Knock Knock 

Came the sound of the door.

"Excuse me... Is this the residence of Soldier Uglix?", a somewhat delicate and difficult-to-differentiate voice between male or female came from outside. "Soldier" is Uglix's class, a class specialized in melee combat. It increases sword and shield skills and serves as the front line in wars.

Uglix squints his eyes and ignores the pain in his stomach. He has no friends or acquaintances in this world and doesn't know who came knocking on his door.

So, Uglix simply licks his lips before deciding to go out and see who it is.

...

Outside, a somewhat delicate figure swallows nervously. This is a figure covered by a worn cloak and tattered clothes. Is a cat-girl, with white cat ears and white hair. Named Koneko, she is a cat-girl who was abandoned by her family at a young age and has been surviving by begging for alms.

For a few days now, Koneko has had no luck, and at this moment her stomach is constantly growling.

In her hands hidden under her cloak, she holds a blunt knife, her eyes showing the killer instinct of a small demon.

As her body trembles slightly from excitement, her heart beats intensely. From time to time, she licks her lips. Somehow, this feeling, when she is about to take the life of the person inside this small hut in a corner of a poor village, her mind harbors certain expectations.

There was murderous determination in her eyes, and her pupils dilated when she saw the door in front of her slowly opening, making a slight creaking sound.

Her hands moved almost by instinct, lifting the knife to aim directly at the heart of the person of whom she could barely see half of their body.

With determination written on her face and the wind cutting by the blade's tip, she thrusts the weapon with all her strength.

Clash

However, despite the effort it took to prepare physically and mentally to kill the old man inside this hut, Koneko simply sees her knife being stopped by another knife. This is a well-sharpened kitchen knife that is blocking her knife with its tip.

Koneko's eyes widen in surprise. How much skill does it take for the tips of both knives to clash and contain the strength of a child and an adult?

Koneko's thoughts collapse, falling into a sea of endless cycles for a moment before she blinks. The next moment, the man made a strange movement with his hands, sending her blunt knife flying and pressing the tip of the kitchen knife against her throat.

The cold blade of the knife presses lightly against the delicate skin protecting her trachea, and for a moment she could feel the edge of death slowly cutting her skin composed of cells, creating a small wound in her smooth skin without the need for strange movements. Only the light pressure of the knife is enough for her body to react to such a threat, some red liquid slides down the edge of the kitchen knife.

Koneko's yellow cat eyes look at the man's figure with fear and terror, but deep in her heart, some hope lies like a faithful soldier in a lost war.

Her yellow cat eyes seem to shine as she observes the man intently.

Until this moment, she had only heard rumors about this man, Uglix, or rather, "Sir Quasimodo, Quasi to friends, although he has no friends."

Rumors speak of a man with the ability to come out alive from any unexpected situation, a man who has belonged to dozens of adventurer groups, who has seen his fellow adventurers die under the claws and fangs of fierce beasts while he, a fat and ugly man, always comes out of the C-rank dungeon alive.
