"Behold, Courier Six! The genius of Big Mountain research facility!" Doctor Borous yelled at the top of his lungs, his green brain jar shaking from the excitement as he gestured at the object standing behind him.

It was a massive space shuttle, based on the Hermes-13 rocket meant for the Mars Mission. Unlike its predecessor, it was further upgraded with a newer version of saturnite alloy and equipped with advanced ion engines based on the propulsion system, which utilized robots such as ED-E and Mister Handy. It was also outfitted with newest sensors, alongside an experimental jump drive technology based on the Big Mountain transportalponder.

The result, a massive space shuttle similar to that, which first carried people to the moon. However, compared to old rockets, which burnt fuel to reach the Earth's orbit. It used rails based on Gauss rifles to accelerate and reach the vacuum of space. The rails itself were located away from the facility to prevent collateral damage and keep the Big Mountain facility hidden from prying eyes.

"It's impressive, I will admit, but what do you expect me to do with it?" Courier Six admitted as he looked over the structure. The man in question was fully dressed in a suit of Pre-War Elite Riot Gear armour, further improved with technologies from the Big Mountain.

The armour itself was upgraded with a newer version of saturnite alloy. It was known for its durability, sharpness, and ability to retain heat for long periods of time. Good heat retention was a boon in certain circumstances, such as blades and other weapons acting on the same principle. However, infusing it with human bones or tissue would lead to the user cooking himself from the inside out and the space shuttle turning into a giant oven upon the entrance into the atmosphere.

That's why a new version of it had to be developed, specifically designed to be used with a human body. Following a year of research, the alloy was adapted to be more usable as armour and promptly named Saturnite 2.0. It was just as resilient as its predecessor, but this time it was even capable of surviving the cloud, without decaying anymore or letting it inside the armour and with the bonus of being hard to heat up.

On the man's back were two weapons, a flagpole known as Old Glory, given to him by Ulysses and further improved with saturnite alloy. The other one, a hunting rifle, known as Paciencia. The latter of which, he upgraded with a scope, extended magazine, and custom action. On the right side of his waist was a custom auto pistol, he received from Joshua Graham, previously a Legate of Caesar's Legion. The weapon was called a Light Shining in the Darkness, which was also upgraded with an extended magazine, silencer, and an HD slide. Last but not least, was a bowie knife called Blood-nap, which rested in a holster on his right thigh.

"Well, my little teddy bear, we were hoping that you would test it out and see if it works," Doctor Dala explained, paying close attention to her favourite lobotomite's movements.

"You want me to test it out? Seriously? Why not send some kind of robot instead?" He argued, crossing his arms in response.

"There is a risk of their internal systems being fried during launch or something. Not to mention, unless you put a true AI on it, their programming will limit them and prevent them from acting in case of emergency," Doctor Zero explained, his newfound confidence shining through.

"And it still doesn't prevent them from being fried," The Courier said, while the scientist nodded. "That makes sense. Having said that, what do you expect me to do? Fly to the other side of the galaxy?" He asked, his voice modulated by the helmet.

"Nothing so extreme. We only want you to take it into space, make a jump from Earth to Mars and that's it," Doctor Zero explained.

"And what if it doesn't work?" He questioned.

"^#!#($%^$^&!$^$," Doctor Eight butted in, gaining the attention of the group.

"You are not filling me with confidence, Eight. Suffocation is not a pleasant death, the same with burning up in the atmosphere," Courier deadpanned, before resting a hand on his temple and sighing with resignation. "Fine, I'll do it, but at least tell me, will I be the only passenger on the shuttle?"

"WE, THE GREAT SCIENTISTS OF BIG MOUNTAIN, INTENDED TO PUT SOME OF OUR FINEST EXPERIMENTS INSIDE, FOR SCIENCE!" Doctor Klein yelled, his volume knob turned up too much, again.

"Of fucking course, but… did you?" He groaned, before glancing over the scientists.

"Klein wanted to, but we managed to prevent it, Mobius helped with his roboscorpions. So, to answer your question, you should be the only one inside the shuttle," Zero responded.

"Should be?" He inquired, his eyes narrowed behind his helmet.

"We ran multiple scans, my little teddy bear, which came out negative," Dala answered, while the Courier sighed.

"At least that's something…fine, let me put on the spacesuit and I will be on my way," He finally admitted, while the scientists cheered.

With a shake of his head and a small smile on his lips, he got down to work. Ever since he had dealt with Think Tank, he began clearing out the Big Mountain, fixing the broken facilities, uncovering new technologies and improving the ones already existing. While he was harsh towards them, it was not without basis. If Doctor Mobius hadn't trapped them in Big Mountain using a reclusive loop to trap their programming all those years ago, the Think Tank would have wreaked havoc upon the world. Still, once they were on his side, their expertise proved to be invaluable in helping the world recover.

They had improved the holograms from the Sierra Madre, making them more aware of their surroundings, deadlier than before, with a bigger range and reinforced saturnite casing that protected the fragile electronics located inside. Then there was his grappling gun as well as bomb collars, not to mention the ability to store Cloud. Furthermore, they improved his pipboy, copying the schematics of all kinds of weapons and armour, even those from before the War as well as those manufactured by Gun Runners. He could easily produce almost anything, including chems and drugs, as well as even the holograms themselves.

There were also the implants, like Kinetic Accelerators, Nanobionic Weave, Bionic Eyes, Nemean subdermal armour and many more. They even managed to scale down the forcefields from Big Mountain, allowing them to be used in actual combat, one of which he had installed in the left arm of his armour. They also managed to replicate ED-E, with all the appropriate upgrades he acquired back at the Divide. Unfortunately, some of the discoveries and technologies came at a price. An unpleasant memory began to surface, but he forced it down and focused on the task at hand.

"I'm in Earth's orbit, do you copy?" Courier asked, fully suited up in a red spacesuit, that he found at the RepCon HQ.

He was sitting in a single chair out of three, located inside the main cockpit. The cockpit itself was fairly unremarkable, Spartan even. Outside of huge console with more buttons, levers and pilot lights than he had ever seen before, it was bare of any human amenities. Metal panels, screwed to the hull, some handles for easier manoeuvrability and one huge glass window with a clear view on the vacuum of space.

"This is Zero, Think Tank copy. How are your vitals, was the acceleration too much?" Zero inquired, relieved that everything went well so far.

"Compared to being shot in the head, it's bearable. You could boost it a bit more, I had to use the engines sooner than I expected. Outside of that, smooth sailing, copy," He replied.

"Glad to hear it, now set up the coordinates and we should hear from you soon enough. The communication will be cut, due to the distance, do you copy?" Zero asked, his voice tinged with excitement.

"Copy, setting the coordinates now, stand by for jump in ten seconds," Courier replied, before shutting the communication down. Preparing mentally for the experience, he began the countdown. "Ten, nine, eight, seven, six," He said, the shuttle humming, a small bubble-like barrier forming around it. "Five, four, three, two, one."

It happened in an instant, one second, he was prepared for the upcoming jump, next he felt like he was put through a keyhole, head first, the agony he felt lasting for a moment, before it disappeared just as quickly as it came.

However, before he could get his bearings, the console in front of him began sparking uncontrollably, the lights in the shuttle dying down, before everything went silent. He blinked, feeling dizzy from the experience. With a groan, he forced his brain to focus on the current situation.

"What the fuck just happened?" He muttered to nobody in particular. Taking a look around, he materialized the pipboy out of thin air and turned on the light. 'At least that one seems to be working just fine…' It was yet another of Big Mountain's inventions, which allowed him to store almost anything without being over-encumbered. This along with his own capacity limit, allowed him to house hundreds of stimpaks, drugs, ammo, special rounds and weapons just to name a few.

Thanks to that, he no longer had to leave anything behind. It was probably one of the most useful things he possessed in the entire history of Big Mountain research facility, their Magnum Opus so to speak. Normally the pipboy was bound to his arm and locked, but the Think Tank managed to take care of that. It also used to look bulky, while the new version easily rested in the palm of his head.

Standing up, he could feel himself float, as the magnetic shoes failed to work. The Courier frowned, brought the left shoe close to his face and gave it a quick glance. It seemed to look fine, but for whatever reason, it didn't work. 'That's worrisome.' Biting his lip, he materialized two pieces of scrap electronics, alongside all the appropriate tools, and began unscrewing the panel. Once all the screws were gone, he looked inside and scowled. 'Everything just melted or straight out fried, it's nothing more but a scrap metal, if it can even be called that, to begin with. Only the wires survived. Wait, what about the rest of the ship?'

Panic began to rise, as he finally realized how deathly silent everything was. Taking a deep breath, he forced himself to calm down and got back to his magnetic shoes. It only took a few minutes at best, before they were back in working condition. Standing up straight, he made his way to the control panel and looked through the window, his jaw-dropping to the ground. In front of him was a planet, similar to the Earth, with oceans, continents, and forests. However, that's where the similarities ended. The shape was all wrong, instead of multiple continents, there was a single supercontinent with a few smaller ones spread out over the planet.

"… At times like this, I wish I never agreed to this whole idea," He muttered. 'One thing is certain, this isn't Earth. Heck, I wasn't supposed to leave our solar system, yet here I am. I swear, at times like this I wish I had vivisected all of those idiots.'

Shaking his head, he investigated the control panel and frowned immediately. No matter what he did, nothing seemed to work. 'Okay, everything is either fried or melted, just like the boots. The reactor most likely shut down and all life support systems along with it. Which means, unless I turn them back on, I will die due to a lack of oxygen if the ship doesn't crash into the planet before that happens. Fuck my life…' The Courier groaned as he realized just how bad things currently were.

He turned around and made his way to the back of the cockpit, where a single hermetic door was located, similar to that of a plane. Under normal circumstances, it could easily be operated by a small control panel next to it. Fortunately enough, one didn't design a spaceship or a plane without a manual override of some description. He pulled a lever located on the door, then began rotating the sluice, until it opened with a small hiss and he made his way to the storage compartment. It was meant to house all kinds of stuff but was left empty on purpose to give the space shuttle clean run so to say. Not to mention, with the Pipboy being far better at storing items and supplies, it was deemed unnecessary.

The only problem was the fact, that the Think Tank did not supply all of the parts in case of an emergency. They calculated that under no circumstances everything in the ship would fail, and only provided back up parts for the engines, reactor, and life support systems, alongside all the necessary blueprints for the space shuttle. 'And that's why you should never trust a bunch of insane scientists in brain jars. I knew I should have taken more spare parts. The only good thing about this whole situation is the fact that I still have got my smarts and skills, so making some makeshift repairs should be doable.'

After that, he made his way to the reactor located in the back. It was a giant cube with some tubes, similar to the transportalponder. And currently, the entirety of it was fried. While he could technically fix it right here and now, he didn't want to waste the only working reactor he had left, in case the shuttle decided to crash on the planet in the nearest future. With his mind made up, he used two fission batteries, some scrap metal and some scrap electronics to jury-rig the reactor into working condition.

Once it turned on, he could see some of the panels sparking, but nothing else seemed to have happened. Turning around he made his way to the life support systems, similar in design to the reactor. And just like the last time, he jury-rigged the whole thing, before it turned back on. A green light told him everything he needed to know, his body releasing a breath he hadn't known he held.

Only after making sure the two systems were working fine, he made his way back to the cockpit and looked at the control panel. He had to manually fix all the components to get this ship back into working condition. He looked up and gazed at the planet below. It wasn't the only thing he was worried about, he couldn't tell how close he was to the planet or how much time he had left before the whole thing came crashing down. Worst case scenario, he would crash on the planet and be forced to create a new space shuttle from scratch. Just as he was pondering his options, something collided with the back of the ship, making him crash into the console with a thud. 'Oh, come on! This ain't fair anymore!'

The planet that he considered far enough to be in stable orbit was coming closer, as the speed of the shuttle increased. One thing was certain, hitting the ground would result in catastrophic damage – for both the shuttle and himself.

He was tough, one of the toughest and deadliest men in Mojave Wasteland, but that didn't make him invulnerable. And the impact of this size could kill almost everyone he knew. He had only one chance of survival. Using his pipboy, he put on Remnants power armour, before making himself comfortable in the seat as he awaited the inevitable. The armour itself was black with an insect-like design of the helmet, black paint and a reactor located in the back. He could see a corona of flame forming around the cockpit as the speed of the shuttle increased, the ship entering the atmosphere. The surface of the shuttle slowly gaining a red hue as the air friction caused an immense strain on the surface.

The entirety of the vehicle was now shaking, as it dived at a sixty-degree angle towards the surface. As he drew closer to the surface, he could see clouds going past him and decided it was as good time as any to do so. Bringing his pipboy close to his face, he selected one drug that would decide whether he would survive or not, Battle Brew. He preferred not to use it unless things were going real south, but at this point, he had no other choice. He could feel as his body became tougher to external damage, the miraculous substance flowing through his veins as the surface of the planet became visible. 'Here goes nothing…'

In the meantime, the citizens of the city of Orario were casually strolling through the city at night, drinking beer, dancing or just going to the Dungeon to grind some more. Those that looked in the sky, could see what looked like a falling star, heading towards someplace on the planet. Many looked into the sky, pointing at it, making wishes and enjoying the show. One particular goddess, sitting at the top of Babel tower found herself smiling, sipping wine from her glass.

"It looks beautiful, doesn't it, Ottar?" She asked her strongest adventurer, a level 7 Boaz person and the only one to ever reach that level.

"Indeed it does, lady Freya," He answered, nodding in response.

"Is there something you wish for?" She asked, gently swirling the wine in her glass.

"I only wish for your wishes to be granted, lady Freya," He answered, while the goddess smiled and sipped some of her drink.

She wasn't the only one to look at the light show, as certain red-headed trickster goddess, by the name of Loki also enjoyed the spectacle alongside the rest of her Familia.

"Look, Ais, a falling star!" Lefiya, an elf with auburn hair, exclaimed. "Quick, make a wish!"

Ais, a beautiful blond swordswoman of Loki Familia nodded at the suggestion and put her hand on her chest and made her wish. 'I wish to become even stronger.'

"I wish for Ais to take me on a date!" Loki yelled, grinning from ear to ear, before a fist smacked her in the forehead, causing tears to appear in the corners of her eyes. The owner of the said fist was from the same blond, she wished for.

"We should make an expedition and see if it brings some good valis towards us," Garreth, a dwarf with a long beard suggested, his Axe resting on his back.

"Possibly, though with the Guild having a rather restrictive policy, it might take some time," Finn, a blonde Pallum responded.

"Even then, it's worth investigating. It could even possess some unique materials not seen anywhere in the Dungeon," Riveria added, her green hair and pointy ears, reminding spectators she was one of the high elves – nobility amongst an elven kind.

"Hah, now you're talking!" Gareth said and laughed, along with the rest of the group, while Riveria rolled her eyes, before permitting herself a bit of smile.

At the same time, a lonely Renart with blond hair and green eyes, looked at the sky, her expression unreadable, while in the slums of the Orario, a young female Pallum also shared the night, her attention focused on the falling object.

The only person to not enjoy the spectacle was the Courier, who was freaking out as everything around him burned. The glass of the shuttle shattered shortly after it entered the atmosphere, the inside of the vehicle set ablaze, while the human held for his dear life to the door in the back, bracing himself for the impact. Just moments before he hit the ground, he cursed his luck, before there was intense pain and darkness consumed him.

When he awoke, he could feel the metallic taste of blood in his mouth. His ears were ringing, his body felt like it was used as a punching bag for a legendary deathclaw and his head felt like it was about to burst. With a groan, he opened his bionic eyes, which were linked to the pipboy, allowing him to see his current status. A quick look at his health bar told him everything he needed to know. It was around twenty per cent, meaning he was one foot in the grave. Thankfully, the Monocyte Breeder and Rad Child were already healing the damage and he could see it slowly replenish in front of his very eyes.

From what he could gather, he was still very much alive and the darkness all around his vision was the result of him being pinned down by debris or something along those lines. Turning on the night vision in his eyes, he took a glance at his own body. His left arm was stuck under a pile of metal, alongside both of his legs. The only thing that was not trapped was his right arm. He pushed on with his left arm and the metal barely budged, but just slightly. He began pushing harder, using the hydraulics of the power armour and his kinetic implants to push away the debris, freeing it his arm in the process.

Once that was out of the way, he pushed away a metal plate, located less than twenty centimetres away from his face. The light of the fire and rancid smoke greeted him immediately. The cockpit was gone, leaving almost nothing remotely similar behind. Small fires were burning all over the place, while the air was dark from the sheer amount of smoke. If it wasn't for the filters in his helmet, he would have a hard time leaving the shuttle without suffocating to death. Pushing off the rubble on his legs, he stood up and made his way out of the shuttle through the broken window, falling on top of the burnt-out ground, breathing heavily. Only after calming down a bit, his breathing slowing down, he looked around.

From what he could gather, he landed in the middle of some kind of forest or near one at very least. A massive crater easily over one hundred meters in a radius was devoid of all plant life. On the edges of it, he could see green trees and grass all over the place, very reminiscent to that of the Earth. However, that didn't mean air composition wasn't poisonous or there wasn't some kind of parasite that infected human brains floating in it. Luckily for him, the pipboy could analyze all kinds of substances and inform him about its effects. Same thing with air. Running a quick analysis, he noticed that the air composition was almost identical to earth, with the exception of less pollution than in his world. 'This is getting weirder and weirder, what are the odds of the same kind of atmosphere?'

Turning around, he despaired as he took in what remained of the shuttle. It was a burning wreck of bent metal, loose wiring, leaking fluids and the saturnite frame which took the general shape of the shuttle. The material was too expensive to create the whole shuttle from, so it was settled upon to only make the frame, which was the only thing that was still in one piece. He could feel his heartache at the destruction of the invention before he managed to get his bearings together. 'Let's see, I am stranded on some kind of alien world with possibly hostile fauna and flora. My spacecraft is worthless, the best I can do is try to salvage as much as I can and take the rest with me so that nobody does anything with it. And on top of that, I could come across aliens, which won't hesitate to put a probe in my ass. Klein, fuck you, sincerely, Courier Six.'

After calming down a bit, he pulled out his Cryo Revolver, a custom energy weapon that froze anything it hit and was deadly against unarmored targets. In this case, though, it would serve well at putting out all the fires. He got down to work, a single bullet was all it took to put out one of the fires and fifty shoots later, the shuttle was no longer releasing rancid smoke into the air. With that out of the way, he could finally start disassembling the whole thing in order to make sure nobody finds it. However, before that, he had to secure the perimeter. He wasn't going to let some kind of alien eat his brains, while he was busy. So, he set down six holographic emitters on the ground in a hexagon shape around the ship, turning them on and setting them to shoot on sight, if something came within the ten-meter radius of the ship. They used the same Sierra Madre security hologram, but far more advanced and deadly, all thanks to Big Mountain for their assistance on improving it.

With the basics secured, he materialized one of his most powerful weapons, Industrial Hand. It was a tool in the Divide consisting of a mechanical glove with a circular saw blade mounted on the back, used in industrial work for cutting materials such as metal or plastics, now repurposed for use as a powerful unarmed weapon. It was just as good at cutting through power armour as it was through ordinary metals. Now with a saturnite blade, it was basically unstoppable, able to completely ignore any and all kinds of armour. Now though, it would help in cutting the ship apart and leaving nothing behind. 'I hope, that I can make it before someone gets here...'

The rest of the day was spent in relative silence, as the Courier slowly but surely took the ship apart, leaving only the frame intact to keep it for the future endeavours. But even then, the ship was massive. It took him about eight hours with the sun even beginning to set and even then, the ship was still only around twenty per cent done at this point. He couldn't finish it in one night, no matter how hard he tried. And he was slowly getting sleepy, his current sleep deprivation hovering at around one hundred fifty of one thousand. 'I should call it a day, for now, being exhausted won't help me in the long run.' With his mind made up, he made his way back to what remained of the cockpit, setting up a Roughin'it bedroll kit on the metal floor and laid on his back, allowing his body to relax and falling asleep almost immediately.

AUTHOR'S NOTES:

So, here is my take on Danmachi crossover. I liked the premise, the lore, the characters of the franchise and the sheer amount of detail. However, I will admit without beating around the bush, I couldn't and still can't stomach Bell's storyline.

Don't get me wrong, he is a good kid and with a personality I can get behind. However, he has got one of the most bullshit deus plot machina in recent memory, Liaris Freese. In Danmachi setting, levelling up is really bloody hard, as in half of the adventurers are still level one despite going through shit on a regular basis. You either need to be suicidal or spend a lot of time practising. Then the author basically said 'fuck it' and gave him ability that makes him level up twelve times faster than the record breaker. Why? In order for him to stay relevant, to be a hero.

I am not saying protagonist can't have broken abilities or be overpowered, just look at the likes of Bleach, One Piece, Fairy Tail. All these have got issues of their own, but there are other bullshit characters with bullshit powers and it's more or less balanced.

In Danmachi, Bell gets unfair advantage, that the author insists is fair. It's not. The reason for Bell getting it is also stupid: love. Why just that? What about the likes of Finn, Ais, Bete, literally any adventurer in Orario? They risk their lives, they have got goals, feelings, emotions, why didn't they get the skill? It's so unnecessary.

So, here is how this is going play out. The story will diverge. Maybe not immediately, but it will. Bell WILL NOT get his broken skill, which is where the Courier comes in. And I think, you will appreciate him being there. Nothing shakes the balance of power more than a guy who can destroy an entire city or murder everyone in it by himself, without Falna.

Also, no pairing in the description. I find it insulting, when the authors tell the ending of the story, before it happens. The journey is far more important than the end goal.
