Everything was red.

The floor, the walls, the empty crates, the windows. There wasn't a square inch of the entire storage area that wasn't covered in either blood or gore.

Dozens of mutilated corpses, Harpies, Centaurs, Kobolds, and Lamias, were hung up and cut open, and placed around a circular perimeter, and in the center of it, a large pentagram drawn with blood, a horrendous display as if the absolute worst of nightmares somehow came to life in all its unholy glory for the world to see.

At the center of it all, a large red pentagram shone brightly, coursing with active Argent Energy obtained from the blood of all the dead liminals, ripping a hole in spacetime connecting the warehouse to the one place no human, at least the ones in this world, ever knew existed. Hell.

To a normal human, such a nasty sight would provoke a wave of shock and disgust, followed by an irresistible urge to expulse their stomach contents.

To a certain green armored man with an indescribable hatred for demonkind, this was just another Tuesday.

Walking towards the pentagram in the center of the warehouse, the Doomslayer loaded an explosive round with the Combat Shotgun, just in case some suicidal demon decided to jump in through the open portal.

The sudden bright flash of red light followed by a looming figure of a tall, thin figure with no eyes and wing-like appendages on its back confirmed his instincts.

The Summoner shrieked loudly for the world to hear, not with the intention of declaring its presence on the world, but simply due to the horrifying revelation that the Doomslayer was right in front of it, shotgun in hand. Now the Summoner realized why the demons it sent through the portal earlier haven't reported back.

A single explosive round colliding with its forehead ended the Summoner's line of thought, smearing brain matter across the cold hard cement floor. The demon fell backwards to the ground, no longer having the capacity to levitate, its face no longer recognizable from all the blood and melted bone, but the Summoner wasn't dead yet. It was still breathing, although barely.

The Doomslayer decided to give it a little taste of his "mercy", by ripping off one of its arms, ignoring its painful cries, and smashing its head with said severed arm, the glorious visage imitating a watermelon smashed open with a baseball bat.

After dealing with the dead demon, whose body slowly disintegrated into thin air for no known reason, the Doomslayer looked upon the pentagram, and thought of an idea. He walked into the pentagram, stood in the center and waited.

Nothing happened.

"It appears that the portal that was formed is only a one-way dimensional rift created with the sole purpose of sending Hell's forces straight towards this Earth with no way back. The demons we encountered earlier could have been a mere scouting party, and they would've gathered the bodies they require to open another portal, in which then the real invasion would occur, had it not been for your intervention." VEGA's voice informed him with his usual robotic tone.

The Doomslayer grimaced a bit. He hoped he could return to Hell immediately to continue his campaign of destruction upon all demonkind. And possibly find a way back to Mars and give Samuel Hayden his "opinion" on humanity's needs, with his fists.

Sighing, he wondered how he could close the portal from this side. While the idea of continuously massacring them while they idiotically jump in from their dimension to this one, unaware that he was waiting for them was fun, he knew the demons were much smarter than that. If they were able to do something like this, no doubt they could do it again, in some other place, where there would be more humans to corrupt, which would mean more portals might be opened. As powerful as he is, he couldn't be at two places at once to stop more portals from opening.

Alone, he could definitely take on all of Hell and come out unscathed, but if other innocent lives are on the line, that's a different story entirely. He may not trust the humans, but even they don't deserve the same fate as hisown world. He could survive, even thrive, by himself just fine, but he's nowhere near capable enough to protect the whole population in the entire world all at once, should a global-scale invasion were to happen.

He was but one man, after all.

He looked around the warehouse, hoping for any signs that could mean some sort of switch, or even a Gore Nest, that could deactivate the portal, only to come to the conclusion that there was none.

Unsure of what to do, VEGA came to the rescue, "Upon analyzing the blood pentagram, I have significant evidence that this portal is more than likely an incomplete version of a Gore Nest, made in desperation by the ones who lack the necessary resources or knowledge to produce one, and as such, the portal itself is incapable of storing massive amounts of pure Argent Energy within, as such a large amount deposited into it would in a way, "overload" and destroy the connection sustained by the portal into Hell."

Upon hearing VEGA's remark, the pentagram suddenly shone brightly, the blood trail crackling with red electricity, until a bright light engulfed the view.

After the light faded away, two hulking beasts with grey skin stood inside the pentagram, roaring loudly towards the one person in the warehouse who was still alive.

Not to intimidate the man, no. They were shocked that he was here, in a parallel Earth where he shouldn't even exist.

VEGA immediately told the Doomslayer the one thing he wanted to hear.

"Doomslayer, you know what needs to be done."

He smirked, pulling out the largest weapon in his arsenal. The only weapon that can produce massive amounts of pure Argent Energy in a single blast, which was just what he needed at this moment.

The BFG 9000 crackled with green energy, the humming sound of pure Argent being concentrated and released into a single projectile, the equivalent of shooting a small sun, filled the ears of the two Hell Knights, as they realized what was going to happen. But they were too late to do anything about it.

A bright green light engulfed the entire warehouse, followed by a horrified roar, before the sounds of flesh and bone being ripped apart filled the air. A large expulsion of energy soon followed, accompanied by strange howls of anguish and suffering, before everything suddenly went silent.

_

Everyone was silent.

The only thing that could be heard was the sound of dozens of hearts beating, and hasty, worn out breaths.

They were shocked, speechless.

After all, the visceral scene of a single man in green futuristic armor obliterating a group of demonic monsters in less than a minute using strange, never seen before weapons, with such brutality that it could make any person vomit in disgust, was sure to make anyone's gears stop working.

The silence felt like hours, then years, then eternity.

"Holy shit."

Until a certain redhead undead decided to break it.

Despite being shaken up by the traumatic event in front of her, Zombina was still arguably doing better than her peers, with Doppel completely frozen stiff, losing her usual playful demeanor, Manako having already passing out from the beginning of the carnage, and Tio covering her face with her hands the whole time while silently whimpering, apparently saving herself from witnessing the horrors in front of her. Though the echoing demonic screams of terror still didn't go away in her head.

The humans weren't having it much better. The SAT officers, were either unconscious since their minds couldn't handle such brutality, or have desecrated the pavement with their lunches.

Overall, their reactions are quite natural, if one were to think about it. Never in their lives would they have had the thought of ever seeing such ferocity and brutality, unprecedented by any human or liminal before, being done by a single man.

No, even calling the Green Behemoth a mere man would be too much of a stretch.

But what shocked them even further, was the amount of rage seething from the Behemoth's person.

As ridiculous as it sounds, the amount of fury harbored by the being was so great, it could be felt by everyone present, despite fury being an emotional state and not a physical thing, despite the being's face never seen, and despite him never uttering a single word.

Actions do speak louder than words, after all.

It wasn't until a loud demonic shriek coming from within the warehouse permeated the air, that the group was finally broken out of their stupor. Followed by what sounded like flesh being ripped apart, and the cracking of bone. And then silence once more.

The SAT had half a mind to go in and investigate, but the other half of their minds thought of simply running away like hell and leaving whatever ungodly abomination await within the building.

The cocking sound of a fully-loaded MP5 broke everyone out of their thoughts, and it came from none other than the undead liminal in front of them. Zombina steadily walked towards the source of the invasion, her submachineguns loaded, much to the surprise of the remaining MON squad members who were still conscious.

"W-wait, Zombina!!! Where are you going!?" Surprisingly, it was Doppel who questioned her teammate out loud.

Zombina stopped for a moment, looked back, and merely grinned.

"To kill those sons of bitches of course."

Zombina never said it out loud, but deep within, she was pissed. Seeing all those dead people, all the destruction, all the blood, and then seeing him, it triggered something inside her. A feeling she had never felt before, or at least, never one so intense. Rage. Pure, unfiltered rage. And a hint of excitement as well.

Walking, then running, towards the warehouse, she looked at her two guns, each one only having one magazine left before she completely run out of ammo. Then she remembered the green armored giant that walked in before. And the gun, no, guns he carried around.

'Eh, that green guy will probably lend me at least one of his toys.'

Menawhile, Doppel turned back towards her two remaining teammates, one of them lying on the floor, deep inside dreamland.

"Umm..hey, Tio-chan..."

The ogre in question, still having her hands covering her face, let out an opening with her fingers allowing her left eye to be seen towards Doppel, and simply uttered, "I...I think I'm going...to stay back. S-someone needs to look after Manako-chan anyway, r-right?"

It was clear that she was terrified, but tried waving it off and retained her usual carefree tone, though the stench and sight of blood and bile was making it significantly harder to do so. Doppel didn't say anything, simply turning back to the warehouse, where Zombina-chan had decided to go into.

She actually wanted to go in. To know more. About how all this even happened in the first place. But most of all, about him.

When she first met the Green Behemoth during their sort-of failed operation the day before, she just thought of him as a humanoid liminal with a strange fashion sense, or one with a serious case of chuunibyou. But then the symbol marked on his helmet, and the moment the man opened his helmet to show his human face, it clicked onto her. Of course, she was a damn good actor, and she managed to pretend like everyone else and acted oblivious to the situation at hand.

Being part of an ancient race of eldritch beings whose true forms cannot be perceived by mortals, Doppel was actually older than people think she is. Her race tend to age slowly, and thus, some of them are even thousands of years old. Not to say that she was that old, probably only near a century at most, but it's not like she would tell others about it. Her mother, who was quite old herself, had told her about plenty of stories that one would now consider to be mere folklore or a children's fairy tale.

But there was one story in particular, that her mother used to tell her almost every night, one that had been passed on from her grandfather, and many more generations before that. It wasn't a mere story, but rather a legend, one that she thought until now, was just a myth.

It told of a man, a human, in a world much, much older than the one we currently live in, who single-handedly fought against an army of unspeakable horrors from beyond the void, originating from a place far from the reality she is in, a place so horrifying, so malevolent, that those who knew about it refused to ever speak the true name of such a place.

To humans, this world would often be referred to as simply, Hell.

The story often fascinated her, mostly because of how ridiculous it even sounded. A single man, rose against the armies of Hell, in his own conquest for vengeance, seeking the dark lords who had wronged him. He wore the crown of the bravest and most powerful knights who sacrificed their lives protecting their world from the demons, and wielded a sword of unimaginable power, blessed by a godlike figure with adamantine strength and speed, and lastly, an armor forged deep in the fires of Hell itself, said to be unbreakable.

There were many variations of the same legend, but all of them used the same name to describe the man in said legend.

A name that, if translated from her tongue into human language, would be simply called...the Doomslayer.

Her entire life, she regarded the story, and the man, as nothing more than an old legend, a tale from history eventually forgotten by the tides of time.

Yet here he was.

And everything that has happened so far today, it almost mimicked the legend her mother told her. The demonic creatures coming from whatever hellhole they originated from, the blood and destruction, and then his arrival.

It was like she was reliving the legend herself.

But some things stood out which made her question her own memory of the tale.

For one, the man was wearing green, futuristicarmor. Never had her mother ever told her that the Doomslayer would look like an alien from space, instead of the usual medieval knight in shining armor. In fact, the armor itself looked quite beaten, the scratches and burns etched across its metallic plates spoke volumes of its true age.

And then, there was the fact that the Doomslayer used firearms instead of a sword, just like how she often imagined it as a child.

Other than that, his actions, his brutality, and most importantly, his wrath, enough to even terrify the demonic beings he fought against, were just like how her mother used to describe it in her stories.

And now, she was unsure of wether to simply stand back and watch from the sidelines, or to follow Zombina and meet this living legend once more.

Curiosity is a powerful thing. It drives us to seek and embrace the unknown. Pushing us forward to uncover the ones hidden beneath, opening our eyes to newfound knowledge, and sometimes, it simply couldn't be ignored.

Humans aren't the only beings who fall prey to such instincts.

Doppel silently cursed.

"Screw it, I'm going in."

-

The blinding light eventually faded out of existence, and the pentagram was no more. The dimensional one-way portal was closed.

The Doomslayer dematerialized the BFG. He had to tread carefully now so as not to spend all of its ammo too quickly. Not that he would be powerless without the big freaking gun. It was just really fun to use. It seemed that he had found a new form of enjoyment in his eons of existence, that is to gaze upon the glorious sight of a dozen hellspawn disintegrate into a cloud of blood and gore all at once.

The sound of footsteps prompted the Doomslayer to quickly turn around and whip out his Combat Shotgun at the ready, and he was greeted by a certain familiar redhead dressed in a yellow vest and dual-wielding what seemed like primitive firearms. He had seen her before, on the day he was first transported into this world.

The redhead in question was gawking at the gut-wrenching sight of dozens of dead liminals, hung open like animals inside a slaughterhouse. She immediately covered her mouth to resist the urge to vomit, and her expression of shock and disgust, eventually turned to fury.

"Who...the fuck...would do this kind of SHIT!??" Zombina was furious. Whoever, or whatever, did this, was no animal. No, they would be worse than that. Monsters. That's what they are. Genuine, heartless monsters who don't deserve to live. She was ready to unload how lead to those despicable demonic creatures who would dare do such a thing, when her eyes came across the silhoutte of a familiar green armored behemoth. And the lack of anything else alive around them.

She clicked her tongue. "Don't tell me...you already killed them all!?"

The Doomslayer simply kept quiet. He didn't reply back, because he didn't feel the need to. But he could understand the redhead's anger. It was nothing compared to his own, of course, but it was still relatable in a way. He simply watched as the redhead started cursing to thin air and throwing her arms around wildly, like a child throwing a tantrum.

He then realized that the redhead possessed no heat signatures within her body, suggesting that she was practically dead, but somehow still walking. Akin to a Possessed. But she did not display any traits that would classify her as one, so perhaps she could be a liminal? Than it would only make more sense on why she would be so angry.

Just then, another figure approached the redhead from behind, also shocked and wide-eyed upon seeing the liminal corpses. She had a small childlike form, and long flowing white hair which seemed to appropriately cover the intimate parts of her naked, dark-skinned body. She didn't seem human, so another liminal as well?

The dark-skinned girl didn't say anything upon seeing him, but her eyes told something else. She was examining him, looking at him like some sort of rare specimen, and even having a hint of admiration towards him. Almost like she knew of him. Strange.

More footsteps followed, and he was met with numerous humanlike figures approaching him, all of them sharing the same expression of horror and disgust upon seeing the contents of the slaughte-no wait, warehouse.

However, most of the human officers immediately had their attention focused on the being in the middle of the large room, the so-called Green Behemoth.

None of the humans said anything, probably too slack-jawed or scared to do so, but the Doomslayer understood why they were here. He was expecting this anyway. He dematerialized his shotgun and stood in silence.

This world had just experienced the first taste of a demonic invasion, and it wasn't even a real invasion force, merely a scouting party. They had no experience whatsoever when it comes to dealing with the monstrosities that lay waiting in the other dimension, and their low preparation for such an attack, had caused many lives to be lost. All that in just a span of a single day after he had arrived in this world, also uninvited, being an anomaly that this world was also unprepared for. It was too much to be a mere coincidence.

There will be many questions to follow. But the Doomslayer thought he should probably just let VEGA do the talking.

Now that he had thought about it, these people don't know that VEGA exists either. The existence of an advanced artificial intelligence inside his armor would definitely raise more questions than there already were.

He sighed. The Doomslayer was never quite a team player himself, but the humans and nonhumans of this world needed to know what they were up against, lest more lives will be lost when another invasion might, and would occur.

But first, he would need to gain their trust back. And he hoped this time, they would trust him enough to not keep him locked up like an animal, otherwise there might be more bones to break.

-

Kuroko Smith, aka Ms. Smith, was having a mental breakdown. Sort of.

It had only been a few days since the incident, and the media was on fire, almost literally.

The cost in terms of property damage was equivalent to a natural disaster. The actual numbers were kept secret, but it was estimated that more than a hundred lives, both human and liminal, were lost. They were lucky the attack happened in one of the lesser populated areas of the town.

Still, it was a big blow to Japan, especially considering the country had never seen war casualties since WW2. Despite the fact that both humans and liminals were affected by the Asaka Inferno incident, as the media referred to it now, many were outraged by the government's seemingly inability to keep the situation under control.

It only got worse after the survivors of the incident were interviewed, where each interview described "hellish, inhuman creatures coming out of nowhere" being the perpetrators of the attack, and of course, such claims caused people to turn their attention towards the liminal society, as the majority thought that only liminals would fit such descriptions of being "inhuman". As a result, several violent small fights and protests had occured against liminals and their rights, caused by human anarchists and protestors, all of which had been safely supressed by the local police.

Even though the government had fooled the media by concluding that it was a terrorist attack and the use of hallucinogens was involved to explain the survivors' outlandish claims, it didn't stop the ensuing cases of human hosts deciding to end their contracts with the Cultural Exchange Program due to fear of their own homestays, forcing many innocent liminals to be deported back to their homelands, far away from human society.

The strain on the Interspecies Exchange Bill had only become significantly stronger than before, and it might be only a matter of time before the ties between humans and liminals are permanently severed.

Everyone, everywhere was hectic. The Cultural Exchange Office was loud and chaotic, due to recent events. In the midst of the chaos, she decided to seclude herself in the break room, and have a cup of coffee to relax her straining blood vessels, which were near the point of literally exploding at this point.

She could only imagine the amount of paperwork to come.

Then there was the matter of him.

The one that had been in the center of attention of the government in light of recent events. The one whose existence had been kept secret during the Asaka Inferno incident. The one who might be responsible for all this.

One day after this man, if he could be called that, suddenly came out of nowhere and trashed her operation, "demons" from another dimension attacked a small town and killed people, also coming out of nowhere.

It was too much of a coincidence.

Smith may be a lazybones, but she actually takes her work seriously when such attention is needed, as in the case of now.

If it wasn't for the reports given by the surviving SAT officers and policemen, as well as her own MON squad, about how the Slayer was actually the one who stopped the extraterrestrial attack, she would've personally begged the Ministry of Defence to just nuke this monster to outer space, and let him bring whatever horrors from the other dimension along with him far away from Earth. But alas, the Green Behemoth proved far too valuable as a rare biological specimen to simply be discarded away, especially since all efforts to retrieve the corpses of the attackers of the Asaka incident failed, since all the corpses of the demonic creatures simply vanished to thin air, according to the personnel on site.

The MON squad had been relatively silent about the whole ordeal. Probably because they were too traumatized by the event. Zombina looked like she could pop a blood vessel at any moment, Tionishia had become less cheerful than usual, which was troublesome since she was sort of the glue that held the team together, and Manako had just woken out of her three-day coma, too terrified to even say anything about that fateful day. Doppel...was different. She seemed like the one least affected by the incident, but she had been asking one too many questions about the Green Behemoth, almost like obsessed about the man. Definitely not her usual self.

Overall, her squad was in shambles. And it was partly her own fault for not realizing the true nature of the mission earlier, and sparing her team the horrors of the incident. Surely the fact that live ammunition was allowed should be enough sign that something was seriously wrong this time.

She had the chance to have a talk with the man after he was brought back to the facility that he managed to escape from in the first place. The subject of the "talk", of course, involved everything there is to know about the man, where he came from, why he was here, and what he was capable of. They already knew what he was capable of physically, but his armor, and his use of strange, never-seen-before firearms had garnered the interest of the science committee towards the Green Behemoth, more specifically the how.

Although, it wasn't really a talk with him in particular. When the Green Behemoth opened his helmet, and then the helmet started talking instead of him, everyone was jaw-dropped, her included.

The AI, VEGA, as it referred to itself as, began an exposition dump onto her, every sentence sounding more far-fetched than the last.

"I am an AI created by an interstellar space agency who had somehow accidentally discovered a portal to Hell of all places, and this guy is actually an ancient warrior who is actually eons old and the only person who could fight back the armies of Hell because Hell itself is so fucking scared of this guy that they wrote testaments about him, and now both of us were transported here for some reason through some sci-fi teleport bullshit and surprise, turns out the demons decided to come here as well, what a fucking convenience."

At least, that was how Smith surmised it.

Of course, it was more than just that, but the rest of the information told by the AI were discussed in isolation, away from the coordinator's prying eyes and kept under the "Classified" files by the government officials and her higher-ups. So even Smith herself didn't know the full extent of the report.

The man in question, the Doomslayer, as that AI said, was far from a normal human, but it would be hard to identify him as a liminal as well. Especially considering he looked completely human on every level. No fur or any extra appendages or tails visible. This man would easily blend into the crowd as a human being, and no one would suspect him as otherwise.

Currently though, the science committee's main reason for their fascination towards the Doomslayer, was the discovery of the unknown element coursing within his bloodstream. Information on said element had been withheld from by the AI, for reasons both of the AI and the Slayer refused to speak of. Instead, the committee decided to do their own research on the unknown element, dubbed the overly cliched Element X, due to its unnatural state of matter. Further fueling the drive of the committee into the research was the recent discovery of the same form of element found in blood samples of various liminal species, though their quantities are highly miniscule. This observation was what made the Slayer's being all the more perplexing.

To put it in comparison, the amount of Element X found inside a single liminal, compared to the amount of the same element found inside a single sample of the Slayer's blood, was like comparing a drop of water to an entire lake.

His strange biological composition, had become the subject of attention of many scientists who wished to study him like a living specimen, prompting the government to classify him as a special case. At the same time, they wanted him to continue staying within theirs and his own terms and hopefully not have him go rogue again. One of his terms being that he gets to keep all of his belongings, more specifically his armor, for his own purpose. Initially, the CESS were against this, but his recent cooperative behaviour towards the government side, as well as VEGA's own opinion on the discussion, have convinced the former to accept on condition that that the Slayer's whereabouts must be monitored 24/7 to prevent any unnecessary "accidents".

And then there was the matter of where he should be staying.

Keeping the Slayer contained inside a government facility was out of the question, since he had explicitly hinted that he would not want to be locked up again, despite the special "luxurious" treatment he was promised. Besides, it would be futile if they were to try and lock him up again anyway, as it had been proven last time.

Making him a homestay for human hosts as a liminal wouldn't work out either. For one, the true purpose of the Cultural Exchange Program was to integrate the different cultures and lifestyles between liminals and humans and allow both to coexist peacefully, despite their differences.

The Slayer has no need for such extensive procedures since aside from his impossible strength, speed, and endurance, and his tendency to not speak at all, he would easily pass off as a normal human, rendering the purpose of the program moot.

Besides, even if he were to become part of the Cultural Exchange Program, the chances of any human host wanting to accept a hulking 6 foot tall behemoth of pure muscle as a homestay were slimmer than the breadth of hair. And it's not like they could just send him back to wherever he came from. Apparently the current 21st century humanity were still too "primitive" to even consider dimensional tethering, as VEGA remarked.

And so a light bulb suddenly flashed brightly on Smith's head, an idea that was so ridiculous, it just might work.

Instead of being a homestay, the Slayer would be deemed a "secondary host", a liminal who would be living under the roof of a human host, but do not have the same privileges and special laws as a normal homestay, and instead would serve as an additional host to care for the homestays living under the same residence as the primary host family, acting as the primary host's assistant.

It sounded unnatural and overall confusing, but a being like the Slayer cannot receive the same form of treatment as a normal liminal would, considering he was too, human, to be regarded as one, despite not being fully human and being of extraterrestrial origin himself.

And conveniently for her, she knew just the perfect host for the Slayer. A host who would desperately need help supporting the half a dozen homestays living under his roof.

Sipping the last drop of her coffee, Smith slowly massaged her temples, hoping to at least be able to take a day off from all this madness.

-

It was supposed to be just a normal day.

Well, as normal as it could be in the Kurusu household, what with having six female liminals living together sharing a single male human host, which was essentially a recipe for destruction.

Knock knock

"-coming!!"

Creak

"Hello the-eh?"

Kimihito Kurusu, the 20-something year old part-time worker, who had involuntarily become the host of not one, but six liminals as homestays, were expecting to be greeted by perhaps the familiar sight of the lazy Ms. Smith, or perhaps another poor lost liminal which he would have to involuntarily host, since that kind of thing is normal for him at this point.

Instead, he met face-to-face with a 6 foot tall giant in strange green full-body armor, exhibiting a sense of cold burning fury of indescribable intensity, its faceless visor staring at him with a ghostlike, unnatural stare that could suck away one's soul like the grim reaper, an aura of madness and hatred that permeates the surroundings echoing through the recesses of the mind where nightmares come to life, the eternal fires of Armageddon burning the souls of the damned, trapped in a perpetual swirl of torment and suffering, and endless cycle of unbridled, unfiltered rage consuming the humanity within until it is no more-"DARLING!!"

"Eh?"

Kimihito broke out of his stupor. He realized that he spaced out for a while, and Miia was looking at him with concern.

"You were just standing there for a whole minute without talking. Are you okay?" Miia's concerned tone made Kimihito slightly flustered, unsure of what to answer. His eyes turned back to the "guest" in front of him. And a familiar black-haired woman in glasses behind said guest, who had a sinister grin plastered on her face, which was almost never a good sign.

"Good morning, Darling-kun!"

Kimihito tried to give the best pretentious smile he could muster. "Good morning..Smith-san..."

"Ahem...I have some good news for you, Darling-kun. In light of...recent events, the Cultural Exchange Program had looked into your case for a while, and I know how hard it is to take care after so many homestays at once, so I decided to bring you a special guest whose company I think you might appreciate! Isn't that nice?" Smith informed Kimihito with an unusual charming tone, which only made him more confused.

"Ahem, anyway I'd like you to meet...Mr. Doomslayer."

The armored behemoth suddenly extended its hand towards Kimihito, asking to shake hands with him, though its sudden movement only surprised Kimihito and made Miia jump back in shock, thinking that the behemoth was an inanimate object.

Despite the armored giant's seemingly friendly behaviour, the aura of silent dread radiating from the being made Kimihito wonder if Smith was really trying to kill him. Taking care of six hormonal female demihumans who could accidentally kill him with their strength all the time was already taxing enough, but this...thing...felt like it was way out of his league. He had never felt this terrified in his life before, and he's had his fair share of near-death experiences.

'This...monster...is going to be my next homestay?'

Author's Note

Man...this took way too long to update. I swear, sometimes my brain just refuses to work with me. I didn't plan to take this long to update, but work got in the way, so I didn't have time.

Anyway, the next chapters will mark the beginning of the Doomslayer trying to live a semi-normal life filled with monster girls, but of course, we all know who is the REAL monster among all of them.

And yes, there will be more demons in future chapters, because it wouldn't be a Doom crossover fic without them right, which means more ripping and tearing, when exactly, I don't know. I'm really just winging it.

In case some of you have already figured out by now, I am trying to converge the two universes of Doom and MonMusu together and hopefully I could come up with a semi-decent lore that could potentially make this crossover more realistic overall and hopefully, more fun.

Until next time, thanks for reading.
