Prologue: The Unvarnished Truth.

AN: Another Crossover fanfiction I wanted to do. When people see God of Wat, they see Kratos and ignore the other characters. But not me. I thought a lot on what crossover to do and I stumbled on KnY (or Demon Slayer).

I will try to make a interesting story and diverge from canon if I can without making the story seem like bullshit.

Anyhow, thank you for giving a chance at this fic!


That is what comes next", Said a vengeful dwarf.

Sindri took the sphere that had Odin's soul in it. Just after Freya managed to forgive herself. After many conversations and many experiences, after the entire war that happened, she managed to forget, but not Sindri.

Kratos hid his shock, Atreus was perplexed and Freya was stunned and Mimir couldn't describe what he was seeing. The dwarf vanished and soon as he turned to them.

He was still mourning the death of Brok. Even if Kratos trying his best to talk with him, he wouldn't listen.

A distant wind is heard until a big "thud" comes after it, "It's Ragnarök! He's here!", Freyr said as he pointed to the sky.

And indeed he was there, ready to strike Asgard and reduce it to ashes. The sword descends with great speed and power, but thankfully, both Freya and Freyr manage to hold the attack.

"Time to go!", Freyr exclaims.

"Where exactly?", Mimir mocks in desperation.

A portal appears behind them and a familiar bark can be heard. It was Fenrir and Angrboda, "Need a hand?"

"...How?", Kratos asks in mildly disbelief.

"Giant stuff", She brushes it off, "Okay, follow me—quickly!".

Kratos and Atreus soon follow as they see the sword going up and preparing to go down with double force. The siblings manage to hold the attack, but it wasn't going to be hold for long.

"Nað...", Freyr says solemnly.

"Yngvi...", Freya reciprocates.

Freyr wanted his sister to leave, to escape, to live. But if he changed a fraction of his focus to her, even if a slight amount, the attack of Ragnarök will succeed in the destruction of everything.

However Freya wanted the same. It's been years since they saw each other. Since they've been in speaking terms. It was since she married Odin and later banished to Midgard that they didn't even had the faint idea to speak wit one another. The reasons for each to do what they did were already something from the past, something they already forgave themselves. Siblings that now loved each other.

The problem was that only one could leave this place alive.

"It's time! We need to go, now!", Kratos warned a last time for one of the siblings to go.

Both face each other. Freyr tries to speak.

"You shou-"

Only for him to be pushed forcefully by her magic to the portal.


Freya used both Thrungva and Mardöll to hold off Ragnarök's attack one last time. Time enough for everyone to be at the next side. She succeeded at the cost of her life.

Funny how it is. Immortality is often interpreted as a "you can't age" when the definition for this is "Eternal". Immortality is that you "can't die", this being the antithesis of mortality. But it was fine. She didn't have any regrets. She managed to do everything she could to repent for her past sins.

Freya only had one mistake she couldn't forget, and that was with Baldur. He was... Misguided? Yes, misguided. She only wanted to prevent him from coming to harm, but the irony was that this simple action caused this entire odyssey to happen. If for some reason she got back in time, she would try to do differently. She would make things right.

All she could do now was lay down in this soft snow she was.

Wait... Snow?

Freya opened her eyes. And she couldn't believe it. She was in a forest? It had snow everywhere. Was she on Midgard? She managed to escape? So she could go back to Freyr? She needed to go after him! After everyone!

Upon getting up however, something felt very odd. Walking took effort. Something that should be trivial to her. Wait... This isn't right, what did happen? She couldn't feel her usual strength. Or worse yet, she couldn't feel her magic, she couldn't feel her wings, she couldn't feel... anything? What was going on?

"Rot!", she tried to bend the roots in the forest.

The results were horrifying. She did manage to lift a few roots, but that's about it. Her overwhelming power she had? Gone, reduced to atoms.

"What is this sorcery?", She asked to no one in particular.

A small breeze made itself know and Freya felt it. And this wasn't the cold of Helheim.This means that either she used more of her magic than she realized or she is being restrained somehow. Judging by how things used to work in her life, it's probably the latter.

No time to panic right now, she needs to find shelter. And quick.


Freya managed to have a safe and secure place to stay. It was a cave (well, a hole in a wall) hidden enough so she could think better on what just happened to her.

One thing was that she still had her wings, but they felt... heavy, strange. She could summon them anytime she wanted and even could fly for a few seconds before being drained by the effort needed. She also could cast a few spells, but judging by the microscopic amount of magic she had now... Maybe two, threw spells a day? Hard to tell.

Not even to mention the effectiveness of the spells. They felt weak and unpolished, which is rather unsettling since she had more knowledge and proficiency in magic than Odin himself. But after a small analysis, her magic was returning, albeit very slowly.

Her strength was also reduced, but still greater than the common person. The problem was the constitution. Even in Fimbulwinter she didn't fell the cold (or rather any temperature). It was always comfortable to be either in Muspelheim or Helheim, but now? It was uncomfortable to put her feet in the ground.

Granted that the "Fate Breaker" armour that Lúnda created covered most of her skin (and feet) but still, snow is snow.


Freya traveled for a few days. She wasn't in any of the Nine- Eight Realms as far as she could tell. She didn't feel the magic in... pretty much anywhere. Maybe the reason her magical power is slowly restoring?

The news made her frightened. It was a totally different realm, one with little to no knowledge in magic, maybe even basic medical knowledge. She theorized that she was transported thanks to the destruction of Asgard to another realm, but if that was the case, Odin's dogs, the Einherjar would hunt her as soon as she woke up, giving her weakened state.

Or maybe she was in another place of the world? Kratos came from Greece, so maybe she was in another Pantheon? She studied along the years, thanks to Týr, that a bunch of other Pantheons exist in the world. But if that's the case, she would be contacted even in her weakened state.

Freya discarded these theory.

She formed another theory. She was probably in another world. A different place altogether. It was quite generous at it was that she still had virtually every single feature that she has.

Anyhow, it did take a while to find another living being aside from wild animals. Thankfully, they were civilized people. Humans, but still, civilized.

While she did find civilization, she did find new things. Thanks to the low-than-average magic levels, she was now dependent on food, water, sleep and... well... bathroom breaks. Of course, she still needed that in her life, but in far grater intervals.

Another problem to deal with, but one that thankfully was solved. And quick. If this world lack knowledge of medicine or medical care, she would use it in her favor. And giving that she lived in Asgard for many years because of the curse that Odin casted, the list of treatment was big. Very big.


Year: 1250 A.D.

A few months later after Freya's arrival

The name "Frigg" quickly became know in these lands. A healer from a far place, using her intellect and skills to help those in need.

She travelled the Shogunate of Japan, spreading the knowledge of "her" craft in every village she came across. A woman skilled in the arts of healing with both impeccable beauty and wisdom? And being a commoner? Truly, this woman was a mystery to the average eye.

She managed to be the uncontested best in the field. From helping simple farmers and beggars to the Noble Houses of the Capital. Thanks to these accomplishments, she managed to achieve great influence, enough to have a lordship.

It was quite a feat. Having a fixed place for work, research and study.

Freya needed to give credit to the Nobles and the Shogun. Due to their efforts and recognition of her abilities, she not only had a "Hospital", but also staff to maintain the place and supply it.

Of course, the more advanced treatments are forbidden. Cutting someone open to remove whatever that is inside the body is not just frowned upon. It's way worse than that. But all the other treatments like medicine, potions, chiropractic care and other treatments were really well received.

After teaching the staff how to operate the majority of the treatments, she started to learn the intricacies of this world and society.

Geopolitics, philosophy, history, maths, social norms, cultural sensitivity, mythology, language... Everything. She couldn't outright make a silly mistake and possibly offend someone that has a "short fuse" as the people here would say. Not even to mention a high temper or big ego.

For now, she would continue this roleplay until she finishes studying.


Approximately six centuries later

Freya had lived for quite a while now. Her magic levels didn't grow up that much. Before she could effectively cast five spells and call it a day. After 600 years, this number only doubled.

She learned all she could, not only about Japan, but the world. It was quite the journey to not only read about things but also witness it. Especially the United States, that place is going far. England was also very nice with their Monarchy. The tea was delicious as well.

China, formerly know as Ming Dinasty, India, formerly known as the Mughal Empire, Egypt, still know as Egypt...

She also visited Greece and the Scandinavians. She learned a lot about the Greek/Norse mythology in ways she couldn't otherwise. It was interesting seeing how very was written in Norse compared to Greek. She did her best to put it in books and encyclopedias. Some stories diverged from what she knew but otherwise they were correct most of the time.

A lot has changed since the Kamakura Period. Especially the Mongol Invasions. Thankfully she made a name for herself (or rather, Frigg). If wasn't for her medical knowledge maybe the Army wouldn't be able to repulse the invasion.

There was also the siege of Kagamura in the next century, the Nanboku-chō Period, the changes of the Shogunate and the Wokou Pirates causing trouble. The next few centuries also had a lot of both external and internal conflict. In 1523 things got so ugly that trading with China came to a full stop. Not to mention the famine and plague that came afterwards.

She wasn't at the country at that time and she couldn't decide if she felt safer for not being there and suffer what was happening or sad because she wasn't helping.

She did come back to Japan a feel times. She discovered that ber Hospital became a Clan, the "Frigg Clan". While she discovered that, a lot of things were happening while she was there. Namely was when she witnessed the Golovnin Incident. The Golovnin Incident involved the capture of The Russian Explorer and naval Captain Vasily Golovnin in1811 by soldiers. Of course he was released a few years later and even wrote a book that spoke about his time in there.

She didn't really read the book, but knew that it was translated world wide. This event also helped in the Russian-Japanese negotiations which helped in taking the Kuril Islands.

She left a year later after knowing about The War of 1812 in the United States. That war originated from the conflicts of the Indigenous Tribes and, well, everyone else. Freya helped as she could to minimize casualties, but the war's results was inconclusive at best.

She would refrain from joining or exploring the world for a while and would rest in Japan until figuring out what to do.

One thing to mention is that, probably because of her "Frigg Clan" that foreigners were more accepted in Japan. Since the trading rout Portugal did to Japan after the Nanban Trade in 1543.

But that's not important now.


1912 A.D. Taisho Period

"Nothing like home", Freya comments while getting out of the ship.

The journey was simple. Wait for a few months on sea to eventually set foot on land. Of course, this didn't mean that it wasn't tiring. Notably being the Goddess of Love, attracting the gazes of most mariners, sailors and passengers.

She is the most beautiful woman alive, yes, but being stared for months is quite... rude.

"Be careful, love", A British man warns her, "I hear that a bunch of murders are happening recently".

"Thanks for the warning. I'll make sure to go on man-made roads", She dismissed the man's preoccupation.

He didn't knew he was speaking with a Goddess, but was still wishing her well-being.

"There is a convoy going to a small village in the north. You should be able to find a spot and go there", The man suggests.

"Yeah, I am not in a hurry to go back to the capital. Might as well relish the ride", Freya says as she stretches.

With a few coins she buys passage to this random village.


"...I never thought that the other side of the world could be so beautiful", says a woman merchant, listening to Freya's stories.

"Indeed. When you visit places you get aware of how little you know about things", Freya says as she shows some parchments with paintings of various locations she visited.

"I wish I could do a fraction of what you did, Miss", A man says dispiritedly.

Freya could only chuckle a bit at his antics. Such theatrics for a simple dream.

"Well, might be a good idea to stop and make camp over here", The man in the wagon says.

"The village is in this roads direction. About... a day until there. We rest here and arrive there by nightfall", says another man.

"Very well, I shall cook a nice meal to everyone", Freya states lifting her non-existent sleeves.

Suffice to say that everyone was pleased by the prospect of eating her food.


Freya woke up in the middle of the night with a eerie feeling. She could feel that something was here, something lifeless. No. Not lifeless, but... bloodthirsty, hungry. But one thing that made her senses flare was that she smelled... Iron?

No, it was blood.

She quickly got up, jumping from her sleeping spot. She saw a pale man, munching over something, covered in blood. The blood of the people of the convoy she was riding with.

"I see. One of you woke up", The creature glanced over Freya, "No matter, it's not like you can do anything to stop me".

"What in all the realms are you?", The goddess asks as she sees the monster in front her.

He lunges forward, aiming to strike her head, only to said strike be dodged with a simple sidestep. He continued his attacks, not caring for a "one-time luck", wrongly presuming he would effortlessly kill her.

Only for her to keep dodging.

"Stay still, dammit!", he screams in annoyance.

"As pale as a white canvas, eyes of unique colour and teeth of a leech... Are you a Vampire, by any chance?", She asks with a gravity of someone speaking of the weather.

"Are you-? Stop this stupid nonsense! Just who the hell are you?", The "vampire" shots back angrily. She was clearly not taking him seriously.

"No matter, I shall kill you for you crimes. Rot!", Freya says as she casts her Chlorokinetic spell.

A bunch of tree roots entangle the man, leaving him stuck in place.

"What is this? Get this thing off me! Are you a De-"

Ignoring the monster, Freya takes one of the swords of the man that tried to fight it. She extends her arm and proceeds to decapitate him. She looked at the people that died needlessly to it. It's a shame, but she will need to-

"That's so fucking funny, haha", A voice scoffed at her.

She looks back to the Vampire she decapitated.

"Oi! Don't ignore me!", The voice came again.

From the head?

"How?", Came a bewildered question out of Freya's lips.

"Yeah, I can't die like that you bitch", He said full of mockery.

"Sorry, its been a while since I've seen a talking head...".

"What?"

"No, nothing, "She quickly dismissed it, "But... How?".

"I'm a Demon. Only the sun can kill me, darling", He says as he looks up at the woman, "That or those guys swords".

"So, a specific material on those swords", She concluded.

"It's really weird how naturally you've taken the situation, giving I am a taking head", The Demon voices his mind.

"Oh, believe me, I've seen my fair share of... weirdness", She says as she remembers the stories of Loki in this world. Let's just say it's... comically disturbing.

"Well, now that you've managed to behead me, can you answer my question?", the beheaded man says as Freya picks his head up to eye him.

"Which is?"

"Are you a demon?"

"No?"

"Why are you answering with a question?"

"Sarcasm".

"Oh".

"..."

"..."

"So...?", The guy asks.

"Well, if you are a Demon with your unique abilities, I can say that I have my own share as well", She says as she puts him in the ground.

"No shit", he says as he side eyes his body.

"How come I've never seen you Demons?", the goddess mutters.

"What?"

"I've been here for about six hundred years, but still I've never seen your species", She says after sitting in the remains of the wagon.

"Sorry ma'am, but I doubt you could have live that long", he says in a condescending tone.

"And yet I made those roots and branches hold your body", she says cheekly.

"...True".

"Well, what else can you tell me?"

"Not much. Partially because I don't want to tell you anything and majorly because if I open my mouth, I will regret it", he says deflating at each word.

Freya absorbed those words. That could mean a plethora of things. From being cursed somehow as to not speak about it, which would probably mean death or even worse. He's traped, but she still needed to consider what move to do next.

Carrying him with her? Not a chance. Even if it's just his head, she could be stopped by a traveling Samurai and be taken into custody. She could destroy the body, but that wouldn't make it die. The next possible option was to wait until dawn. But if someone sees her at the center of a massacre, people will start asking questions.

"In that case, you aren't useful to me anymore", Freya says as she gets up.

"What are you going to do?", The demon asks nonchalantly.

"Rot", the Goddess commands the flora so the body of the Demon gets far above the ground with a great view of the sky, "I will take you for a walk, nothing too serious".

"What? Where are taking me? And where is my body?", his confusion was starting to become a more worried tone.


The walk to the village was annoying. The vague and empty threats of her "belt companion" filled the night with nothing but a test of her patience. Thankfully, her suffering was rewarded with the most terrified face she's ever seen, thanks to the Demon becoming Ash as soon as any sunlight touched it's pretty stupid face.

It was cathartic in a way.

However, the question is still unanswered. What are these Demons? And how in her six plus centuries she has never encountered one? At least she know that the sun and "those swords" can kill them.

But what can possibly be those swords? The obvious is that they're made of a specific mineral. Adding the evident weakness to the sun and the search area for it goes down tremendously.

For now, she arrived the village and the only thing she needs right now is a bed, food and a good night's sleep.


In the middle of the snow in a small house, a boy in the outside could be seen chopping wood.

He is approximately 5 feet, 5 inches tall, dark red eyes and with a mix of black-red hair. Average height for Japanese, as well as average build. One particular and quite obvious feature is the scar in his forehead, akin to a small-degree burn.

The boy is wearing a checkered, black-and-sea-foam-green haori over a white robe and black pants. In his neck, a turquoise scarf with circular white bands looped around his calves.

"Tanjiro! Where are you?", A childish voice shouts from afar.

"I'm here!", The boy answers as he chops another wooden log. He is using similar clothes as the woodcutter, albeit a plain green haori.

A small boy with similar features walks over, "Mom said that the coal cooled out", The boy warns while bringing more wood and an axe of his own.

"Thanks Takeo, I'll go right away", Tanjiro cleans the sweat in his forehead.

"Oh, and Nezuko said that we are eating rabbit today, so she needs some vegetables", Takeo adds as he starts preparing to swing his axe in the wood.

"Got it!"


Coal burner.

That's what not only Tanjiro does, but his ancestors before him did as well.

The Kamado Family, Coal Burners.

In the contrary to normal belief, he was very much content in working like this. He had his family, his own house, a stable job that would still go around, even if somehow they managed to replace coal.

After all, people still used swords. He heard stories about fire weapons and how a small projectile could kill someone as far as a marathonist could run. As far as a horse could run.

He shivered after having the mental image pop up.

"Hey Tanjiro!", A woman waved at him.

"Miss Fubuki", He complimented the woman.

She was a usual customer of the Kamado Family. The woman owned a small farm in the village. Always bought coal in the same date of the month. It was quite charming to see her since she was so nice to him and his family.

The days where she would land a few lettuce and tomato are always the best.

"There you go, and it will cost 3000 Yen", Tanjiro says as the woman pays.

"Give your mother a hug in my behalf!".

"Sure!"

It's always nice to know everything and everyone that goes around in the village. If you or another citizen had a problem, everyone would take a small amount of time to help you. Be it a food problem, health problem or water problem, a solution would come.

That's why Tanjiro was content with his life. He had all that he could possibly ask for.

bump*

In his daydreaming, he bumped in someone.

"Ouch... Sorry, I wasn't looking where I was going...", His speech slowly stoped as he saw who he bumped into.

It was another woman, but a foreigner. She clearly wasn't from Japan, as far as he could tell. Not even a naturalized citizen or daughter of a foreigner. She was... Different.

In a sense that this was the most beautiful woman he has ever laid his eyes on. And he had his mother and sister at the top two.

Of course, he didn't see that many woman, so call him biased.

"Are you alright, youngling?", The woman said with a dialect clearly of someone older than it looked like. Her accent was... Inexistent?

"Y-youngling? Yes! I am fine," He says as he gets up and dust off his clothes.

The woman looks at him with some interest. As if judging him for a few seconds.

"Just be careful. We are in dangerous times", The woman says as she heads to the small hotel of the village.

"Umm, e-excuse me! Are you going to stay around?" The boy asked aloof.

The woman eyes him with a unreadable expression, "Yes, I'll take my time here. Why? Are you going to show me around?".

"If you want. I'm going to deliver coal, so I can introduce you to it while I do my errands", His speech was far more coherent now.

"Sounds good", She says with a shrug.

Tanjiro shows the village to the woman. The food they have, the drinks, the farms and other worth-to-mention places. She was listening with awareness and taking mental notes to herself. As they walked, Tanjiro also finished delivering the coal and was ready to head off home.

He couldn't get off his head that she was older than she looked for some reason.

"And with that, that's all I can show you. It isn't a lot, but if you need anything, just let anyone know!", He says with vivacity.

"I'll keep that in mind. For now I could really have a food and a drink", She says puting a hand in her belly.

After sniffing the air for a bit Tanjiro pointed out in a general location, "Well, looks like Mister Hayashi is cooking some Fish down the street".

"How can you...?", The woman was quite surprised at his "ability".

"Oh, I have a good sense of smell, so I can tell how some things work thanks to it", He says in a bashful manner.

"Thank you anyway. I didn't get your name, mister...?"

"No, I'm not old enough to be called a 'sir'. But the name is Tanjiro. Kamado Tanjiro", he says awkwardly, "What about yours?".

"Freya", The woman says after a few seconds of thinking.

"Wow, that name is foreigner", He says a bit surprised.

"Oh, imagine when you hear the stories about my travels. You will be amazed by it", Freya says as if she has just discovered the biggest gossip of the Japan Empire.

"If that's true, I'll be around tomorrow selling more coal. I will be eager to hear you!", He says as he waves goodbye to her.

See? That's why he is content with his life here. Not only can he have the most happy neighbors in the village, but also adventures and tourists that travel the world.

He only hopes that this can last forever.

Getting back home, he gets a very weird feeling. Akin to dread. He did something terrible today, something he won't be able to forgive himself.

He forgot the lettuce and tomatoes.
