In the deepest floor of the dungeon, the final battle that will determine the fate of the world is taking place. A young man from Japan, tasked by a Goddess to defeat the Devil King of this world, is in the midst of this battle.
Before coming to this world, he had always worked tirelessly to protect his family's home from disasters. However, despite his efforts, no one ever understood or praised him. Tired of his miserable life, he chose to leave that world behind.
Or perhaps, he had no choice but to leave that world. The whims of fate are cruel. Even his death was pitiful—he died in fear, wetting his pants because he thought he was about to be hit by a truck. In reality, it was only a slow-moving tractor approaching him.
Even when his parents heard the news of his death, instead of crying, they laughed at how he died. That's right, his name is Satou Kazuma, and he is an adventurer. Right now, he is facing the Devil King.
Before this, he was just a weak adventurer. But due to Aqua's reckless actions, he was forced to take matters into his own hands.
Kazuma teamed up with the former general of the Devil King's army 'Vanir' to help him level up and earn skill points to learn various skills. But he didn't stop there.
He exploited the leveling system in this world by resetting his level with Vanir's help and repeatedly leveling up again.
In this way, he gained more skill points than anyone else and learned more skills than anyone else.
However, despite this, he still couldn't harm the Devil King.
That's why he planned to use the strongest magic he had learned from a certain loli girl in his party.
Kazuma's hands began to glow, signaling that the explosion magic had been successfully activated.
After seeing Kazuma attempt to use explosion magic, the Devil King was taken aback.
"Impossible!!!! A low-class adventurer who can't even use high-level magic can use explosion magic?"
"There was a girl who loved this magic very much. I accompanied her every day as she used this magic until I learned it naturally. At this close range, you will surely die."
"Stop! Aren't you afraid of dying? You will die using magic like that in this room. Besides, that magic might not even hurt me."
"I'm very afraid of dying. I've experienced it many times, which is why I fear death so much."
"Stop that! If I die, all the knowledge I've gained will vanish from this world."
"I don't care."
Kazuma replied coldly.
Then, Kazuma recited the incantation for the explosion magic.
"Darkness blacker than black and darker than dark, I beseech thee, combine with my deep crimson.
The time of awakening cometh.
Justice, fallen upon the infallible boundary, appear now as an intangible distortions!
Dance, dance, dance!
I desire for my torrent of power a destructive force: a destructive force without equal!
Return all creation to cinders, and come from the abyss!
This is the mightiest means of attack known to man, the ultimate attack magic!"
EXPLOSION!!
"BOOOOM!!!!"
...…..
In a large mansion, the four members of the hero party who had successfully defeated the Devil King were having a farewell party.
"Aqua, Kazuma, do you really want to go back to your original world?"
Megumin and Darkness asked them both in a sad tone.
"Megumin, Darkness, I am a goddess. Even if I return to heaven, I will always watch over you from up there. If you miss me, you can join the Axis sect; that way, you'll be able to see me more often."
"I refuse that."
Megumin and Darkness instantly replied. Having experienced the madness of the Axis sect members firsthand, there was no way they would want to join.
"Kazuma, why are you so quiet?"
Megumin asked again.
Kazuma remained quiet and said nothing. His feelings were a mix of confusion and turmoil.
Both Darkness and Megumin had already expressed their feelings for Kazuma. He liked both of them, but deep in his heart, he couldn't act on those feelings. Despite his perverted thoughts and his tendency to 'accidentaly' steal women's underwear, Kazuma didn't want to play with a woman's sincere feelings.
Hesitantly, Kazuma answered Megumin's question.
"I'm sorry, Megumin, Darkness, but I want to go back to my original world. Don't worry; we will definitely meet again. Don't forget, I have Teleport magic, and I've asked Goddess Eris to grant me the ability to use this magic to travel between worlds as a reward for defeating the Devil King."
"I see. If that's your choice, Kazuma, then I won't oppose it. But don't make me wait too long; I will definitely miss you."
"That's right, Kazuma! Don't make us wait too long. When you go back, the Dustiness family will treat you well, so make sure to visit often!"
Unable to bear the situation, Kazuma tried to change the subject.
"Come on, don't be so dramatic. This is just a temporary farewell. Aqua, let's go home; you've prepared everything, right?"
"Eh, of course! We can leave anytime."
With his forced smile, Kazuma said his final farewell.
"Then let's go home. See you again, Darkness, Megumin."
Aqua pulled out her Scepter and contacted Eris to activate the magic circle that would take them away.
"HEYYY, Eris, hurry up and activate the magic circle! I can't wait to go back!"
"Okay, senpai! Thank you for your hard work. And Kazuma-san, I'm so proud of you!"
Moments later, the magic circle appeared beneath Aqua and Kazuma. The circle lifted their bodies slightly off the ground. But just as the magic circle was about to dissapear, Megumin suddenly jumped into the circle and hugged Kazuma.
"I can't accept this! I don't want to be separated from Kazuma. Wherever Kazuma goes, I will follow you. Please don't leave me!"
"Hey, hey, Megumin, what are you doing? Let go of me!!"
"No, I won't let you go!"
Seeing this, Darkness couldn't just stand by and instinctively jumped into the magic circle as well.
"Megumin, that's unfair! I don't want to be left alone in this world either! Kazuma, take me with you too!"
Inside the magic circle, Megumin and Darkness hugged Kazuma tightly, as if they wouldn't let go of him even if their arms were severed.
Not long after, the magic circle began to malfunction.
Cracks appeared at every corner of the magic circle.
Kazuma quickly realized that something was wrong with the magic circle.
It might be because there were people who weren't supposed to enter the magic circle.
"Hey, hey, Aqua, what's happening? Something is definitely wrong here!!"
Kazuma asked Aqua in a panic.
"How would I know? I've never experienced this before?!!"
"Eris, Eris, help me! I want to go home!"
"Aqua-senpai, it seems there's a mistake. Wait—"
Before Eris could finish her sentence. They have already vanished from this world.
….
In another world, there is a city called Orario. This city is known as the only city in the world that has a dungeon. At the center of the city stands a tall building called Babel, built atop a dungeon.
While everyone was going about their usual activities, suddenly a magic circle appeared in front of the Babel Tower.
The magic circle attracted the attention of everyone, both outside and inside the Babel Tower.
After glowing for a minute, four silhouettes emerged from the magic circle.
One was a blue-haired woman radiating divinity, as if announcing that she was a goddess.
The other silhouettes were of an ordinary man tightly embraced by two women.
Several groups of adventurers planning to enter the dungeon were taken aback by this scene.
"Hey, look! A goddess has descended from heaven. Quickly, report this to the guild!"
"Yes, Captain."
"Really? But why are there humans beside the goddess?"
....
At the guild's reception area.
An adventurer, panting heavily, rushed in and tried to report the situation to the elf woman in front of him.
Eina Tulle, a guild receptionist who handles dungeon matters, had typical elf-like ears and bright emerald green eyes. With her beautiful smile, she tried to calm the adventurer standing before her.
"Please calm down. Speak slowly. What happened?"
"A large magic circle suddenly appeared in front of Babel, and from that circle, a goddess emerged. I think she just descended from heaven. But beside the goddess, there were also three humans."
"What?? A goddess descended from heaven? And she didn't come alone, but brought humans with her? I'll go greet her right away. Thank you for your report."
After hearing the adventurer's report, Eina immediately ran toward Babel. But in her heart, she had a bad feeling.
'This is really strange. Gods or goddesses descending from heaven to lower world is normal, but I've never heard of one bringing humans along. And where did those humans even come from? I need to check this out right away.'
---
After a few moments, the magic circle vanished.
Kazuma, Aqua, Megumin, and Darkness opened their eyes and took in the first sights of the new world they had arrived in.
In front of them stood an enormous tower, with many people entering and exiting. Judging by their appearance and the weapons they carried, they were likely adventurers or something similar.
Before the group of four could express their surprise, a female elf approached them.
"Hello, Goddess. Welcome to the Labyrinth City of Orario. I'm Eina Tulle, a guild receptionist overseeing all matters related to the dungeon."
The four of them stood frozen, unable to process what they had just heard.
"Hey, hey, Kazuma, did you hear that? She called me a goddess! This is the first time someone's recognized me as a goddess right away. It seems like the people here have good eyes."
Kazuma ignored Aqua and asked the elf woman, "Wait, Eina-san, did you just say 'goddess'? You know this woman is a goddess?"
"Eeh?? of course. She's radiating divinity, so of course she's a goddess. By the way, who are you three? What's your connection to this goddess?"
Just as Kazuma was about to answer the elf's question, Megumin interrupted their conversation.
"My name is Megumin! My calling is that of an archwizard, one who controls explosion magic, the strongest of all offensive magic!"
Megumin introduced herself in a grand way and make a pose that made her looks like some humanoid thing would appear behind her and ready to punch anyone while screaming and repeating the same word again and agian. Eina Tulle was at a loss on how to respond to Megumin's unusual self-introduction.
"Aaah… I see."
"M-my name is Darkness. I'm a Crusader, n-nice to meet you."
For some reason, Darkness also introduced herself with a shy expression.
Aqua wasn't going to stay quiet. After living so long in the lower world, someone finally recognized her as a goddess. Aqua felt this was her moment and began to introduce herself.
"Hehehe, I am the Goddess of Water, Aqua. I am the goddess who governs water in this beautiful world! Oh, by the way, this is Satou Kazuma. He's my follower and an honorary member of the Axis Sect that worships me."
"Oi, oi, who said I'm your follower?! Don't make things up!!"
Before the situation got any more complicated, Kazuma spoke to Eina Tulle.
"Eina-san, can we talk somewhere quieter? I think you need an explanation, and we also need to explain what just happened. Besides, we're not comfortable being seen by so many people like this."
"Ehh? I'm sorry! In that case, let's talk at the Guild."
