Once upon a time there was a demon named Vanir.

This story has nothing to do with him.

One say the guy named Kazzzuma woke up and decided that he wanted to try bench pressing.

"If I get stronk then I can bully Aqua better."

He went to the gym.

But there is no gym in Axel.

"I'm gonna make a gym," said Kazuobama.

And thus begins the story of how Kazuma founded Axel's first gym.

"Yo, mohawk guy. Im gonna make a gym."

The mohwak guy slowly lifted his head and gave a knwoing smirk.

"Hbabsbanfjdhabd."

Kazuma nodded. "You are jmtruly wise and mysterious. Thank you for your advice."

Following the mohwawkd's advice, Kazuma decided to build his gym right on of the Axis Church.

He got approval instantly.

"I can't wait to see buff guys qnd girls here all the time," said Cecily, drooling in anticipation. Kazuma did not tell her that a lot kf gtm patrons are out of shape people who want to get into shape.

First the roof was removed.

"Explosion!"

Megumkn removed it and then went to jail for casting a dangerous spell in a civilian area.

"Worht it," she said.

Now Kazuma can Starr building th gym. He gave Aqua 53 eris to help him build it.

Aqua refused the payment, because her arr is beyond the concept of value. She build 5 additional stories on top of the rootless church building, and painted it all in various shades of burgundy and lilac.

Now Kazuma needed weights for his gym. He went to Wiz's shop.

"Hello Wiz, I need sum weights."

Wiz was not there, so Kazuma just picked up the heaviest objects that were there.

"Aleight, these cursed tungsten cubes that were found in a dungeon should do the trick once I put handles on them."

He carried them all back to the gym. But in doing so, he raised his strength stat by a factor of 2.67.

He had become swoler. He immediately went back tot he mansion to show off.

"Boom! Bang! Firepower!!!" He flexed at the dinner table where the girls were trying to enjoy a nice bowl of beef stew.

Darkness took it as a personal challenge and started flexing in response. Aqua ignored him and got another rbowl of stew.

Megumin was inspired. She had a higher strength than Kazuma originally because of her higher level, so surely she could reach even greater heights if she trained.

Making her way to the gym, Megumin began lifting the cursed tungsten weights every which way she could.

And after much work...

Megumin had become...

A much stronger Megumin. Due to the hormonal differences between sexes, she did not gain as much muscle mass as Kazuma did, but her strength had increased drastically. In order to truly evaluate her strmetgj, she challenged Kazuma to an arm wrestling contest.

Kazuma refused because he was too busy flexing. Megumin punched him in the head and knocked him out with ease, and then challenged Darkness to an arm wrestling contest.

Darkness took her head on, excited to finally have a worthy rival in her muscle training passion.

When Aqua gave the starting signal for the match, the table immediately shattered beneath their power. They continued the match with their arms in midair, the resonating force from their match causing the air to ignite, blinding Aqua, the referee.

Neither girl would yield. Megumin, as the greatest genius of the Crimson Magic Clan, was determined to show what she was capable of. Dustiness Ford Lalatina, on the other hand, refused to concede to this newcomer, wanting to show the results of her lifelong training and dedication. She hadn't trained with the legendary tungsten cubes, but she still had the experience and muscle necessary to overwhelm any opposition.

Or so she believed.

A strange light was forming around Megumin's arm. Magic power was gathering about her hand, amplifying the power of her physical muscles. Darkness was refusing to yield, but Megumin likewise refused to admit defeat.

Her eyes glowed as the power coalesced...

"BICEPS EXPLOSION!!!"

With a great roar, the mana gathered around Megumin's arm combusted violently and forced her and Darkness's arm downwards...

But they did not reach the horizontal parallel. Darkness had held on. Even the greatest muscle magic had not brought her to defeat. With a great struggle, Darkness started to push Megumin back.

"You have become truly strong Megumin... but I WILL NOT LOSE!!!" As she shouted that, Darkness made a great push that flipped Megumin's entire body over, after which she was slammed against the floor.

But sadly, Aqua, after being blinded earlier, had retreated to her room,m tk drink wine, so there was no referee to determine whether any foul had been committed. So the match officially ended in a draw.

With her newfound love of weightlifting, Megumjn invited Darkness to be workout buddies at Kazuma's gym. Kazuma himself was haply just to reap the income from the gym. Having been disheartened by the difference in power between him and the girls, Kazuma had decided that he should stop comparing himself to others and just be the best him that he could be, and his mental health recovered.

Then Chomusuke ate the tungsten cubes and became a goddess. The end.

Also the curse from the cursed tungsten cubes is that anyone who touches it becomes addicted to muscle training, but that would've happened anyways so the curse was rather inconsequential. Apologies to Keele who thought it was a really clever curse.
