Is it wrong to be a Hero in a dungeon?

A crossover if Fate/stay night and is it wrong to pick up girls in a dungeon

Chapter 1: A brand new world

"This is it uh?... my end…. I have to say, I have no regrets, I avoided the path that made Archer" Shirou Emiya thought as he breathed heavily.

His body was heavily injured and losing blood.

He was content with this ending, he had managed to protect the world.

Yet… as bittersweet as it was he would never be considered a hero… he had left no legend to speak of and thus he would never be a heroic spirit.

"It's my win… ARCHER" Shirou thought with a smirk.

He then fell to his back and closed his eyes for the last time.

He let himself go… it was a shame really, but he would finally be reunited with her.

However his death was to be postponed, either by chance or miracle or what have you his body vanished as it dissolved into blue particles.

Elsewhere

My name is Hestia… goddesses of the hearth, I came to Orario to establish a Familia… and to be honest I have lucked out! I managed to find a cute adventurer who accepted me! Even if I was just starting and our HQ was in a secret room of an old abandoned church he choose me. His name is Bell and he is my first child of my Familia.

We were in our way to register our small Familia when something in the sky just… cracked. This has never happened before and thus both Bell and I were shocked… it only doubled when we saw a person fall from said Crack.

"Goddess watch out!" Bell yelled as he tackled Hestia.

From the sky a young man fell into the ground forming a crater on the ground.

"Oh my goodness… we need to help him… he is badly wounded!" Hestia said.

"Is he a god?" Bell asked.

"No… he is a human like you" Hestia said.

Bell and Hestia both carried Shirou to their HQ.

After contacting her old friend Micah they managed to get a healing potion to help the young man healing.

Shirou dreamt that night.

He was in a hill, the place was sunny and green grass covered the hill… he walked up to find her…

"Saber"

"Shirou"

"I am back"

"No…. Not yet, as much as it sadness me it is still not our time to meet, you have to do it… remember what you said to him? That promise?"

"I see… yes, that's true, I already caught up to him… now… I have to surpass him"

"Because that is the Emiya Shirou I feel in love with"

She walked closer to me and I embraced her, she out her arms around my waist.

"Go back… and carve your legend, don't worry I will always be waiting"

"Yes, and I will always be searching for you"

Back to the real world

Shirou felt tired and in pain, after the ordeal he went trough it was little surprise he was like this… wait… no… something is wrong, he couldn't remember what had happened to him but he was sure that whatever he had been involved in had certainly ended him. That should have been the end of him.

After all he saw her.

With some effort he cracked open an eye, thankfully the pain and wounds had decreased in intensity, he was sure Avalon had some part in this, but since Saber was nowhere the golden sheath wouldn't work as well as it could otherwise be. That meant that there was external factor in play.

He moved a bit, shifting around to find a young boy with white hair and a girl with dark hair sleeping in a sofa.

That meant that he was in a bed, he felt uncomfortable at taking their space but appreciated their help.

2 days later

Bell woke up as he careful slid his way out of the sofa to not disturb his Goddess rest. He looked at the young man who seemed to be sound asleep. Bell couldn't help but be surprised, his wounds had decreased so much that he looked almost healed, when he first saw him he was a bloody mess, if it wasn't for the fact that he fell out of the sky he would have thought that either he ran afoul with some of the dungeon beasts or he had been savagely beaten in a robbery.

It was Hestia who suggested the use of the bed for him, at first she said that Bell and her could share the bed but Bell declined and thus this was the new arrangement for the time being.

Hestia was severely surprised by this young man appearance, she thought it was a god or a demon but after seeing him closely and noticing the lack of inhuman presence in him.

Still she and Bell couldn't leave him like that, he would surely had died had they hadn't done anything and that would leave a foul taste in her mouth and sweet Bell was such a kind soul…

Well if anything at least she had some more Bell time due to this arrangement, however momentarily it may be.

It was then when Shirou woke up.

His body was feeling stiff, which in itself was no surprise as he was bedridden for a few days.

"Ara… you are awake!" the girl said.

I swallowed my saliva when I saw her… this girl.

She was a dead set for Rin… save for one critical area.

I don't want to hurt anyone with my thoughts but it is just so glaringly obvious that even if I say nothing people will just nod and say "Yes, I see".

While 99 percent of her looked just like her, the fact is that she had breast size comparable to Rider's or Luvia could just not escape notice.

"Bell and I were so worried when we found you! You were nearly dead, thankfully I had an old friend who helped us procure a health potion, but I must say you heal very fast! Micah was sure you would need a week or so to be stable, he wasn't sure you would make it! Ah! I am being rude, I forgot to introduce myself, My name is Hestia! Nice to meet you! The young boy here is my "child" Bell, welcome to the Hestia Familia" she said with a heartwarming smile.

"Ah, goddesses we have to register at the Guild!" Bell said.

Wait… Goddess?

It took me a minute to get my bearings as I used my 6th sense and then it hit me.

The girl in front of me was not human.

The power inside if her dwarfed Ilya's when she powers her Berserker, more than that of Zelretch.

Wait… but the Age of God's…. Gilgamesh ended it didn't he? I know a few survived but they became shadows of their power or returned into the ether.

"You can can stay here until we come back just rest up, even if you are healed you must be tired" Bell said.

I nodded as they left.

There was a small table with a glass, a pitcher of water and some bread.

I pushed the cover off me and made my way to the table, I grabbed the pitcher and poured myself a glass.

I was thirsty, I greedily drank the glass and poured myself another.

I tried the bread, it was good, it was still warm so it was fresh so I ate it.

I was unsure what was going on and so I concentrated as I expanded my awareness.

There were a lot of individuals where I was that where not human.

It seems, however unlikely, that I had been sent to another reality.

I first suspected that it may be Zelretch's doing, but I had not detected his particular scent of power anywhere around me.

Still thought, who could had done this to me, and more importantly… why?

He had no choice but to wait for the duo.

He had to admit,The Goddess Hestia was…. Nice.

He decided to learn a bit more about the pair, why would a Goddess stay in such place in the world and have a young boy as part of her "Familia"... whatever that is.

A fair amount of time had passed and both returned. It was there when I asked the pertinent questions that I had.

"Where are we?"

"We are in the city of Orario, one of the biggest cities in the land" Bell answered.

"I… I see" I said as I registered the name.

Definitely another world,as no such place existed where I was from.

"I couldn't help but overhear that you registered a… Familia, was it? What is that?" I asked.

"Ah… I can answer that" Hestia said as she raised her arm enthusiastically. "A Familia is basically a god/Goddess group of adventures, they basically are part of the family of the deity! Different deities have different expectations and some had a 'type' of people they accept, I am currently looking for people for my Familia, the only one I have is Bell since I am not well known and I just started… a benefit of joining a Familia is that you can enter the dungeon and receive a Falna, that is to say a blessing of a deity to help you grow as a person and help you in the dungeon that most adventurers go to, as it is one of the ways to make money" Hestia explained.

I considered my options, on one hand I could thank them and cut ties with them and venture on my own, that wouldn't be bad, but we are on a different world and from the small exchange I could tell that this Goddess was very… human.

She was a bit ditzy and kind, and they boy that had joined was fresh meat… no way he knew how to fight, he could get killed of he went to a dungeon, he could tell from looking at his hands.

Joining them had also opened another door, by joining he would get a Falna, or blessing and help him grow…. He didn't know how that would work but it would be nice to have a boon from a kind deity rather than the MANY deities that are assholes.

A lot of deities sneezed very hard that very minute

Also he would be able to earn money and be able to afford food and lodgings.

After careful considering his options he sighed. "If you think me worthy… I wouldn't mind joining your Familia"

Hestia smiled in delight as he clapped her hands. "That is so great! My Familia is growing already!" she said sincerity happy at this.

She asked me to lay on my back as she straddled me.

"A falta is the only magic a deity can use in the lower world you see… we have collectively decided to seal our powers while here, the blessing is very simple… I pick my finger and a but of my blood will hit your back and create the Falna, this Falna will indicate your strength, speed, Intelligence, magic potential and list any skills you may have. Ah… be sure not to show it to anyone except members of your own Familia, ok? This is secret information of yourself so you don't want people nm owing that kinda stuff, ok?" she said with a smile.

I could sense the essence of her power permeating my back as I felt a small change in me...then she gasped.

"Goddess… is something wrong?" Bell asked.

"No… not wrong… just… unexpected… or rather… shouldn't it be impossible? And what's this? I don't recognize this at all?" she said as she was confused by something she saw.

I was confused so I asked what was wrong.

"You see…. Since you just joined you are level one… most people on level 1 don't have any skills until they upgraded their status…. So you having a few skills is kinda...unheard of" Hestia said.

And thus I asked what where those skills.

"Magic Resistance… Mind of the eye (true) and Erei?" Hestia said confused at this development.

Okay… I could understand the first 2… but that last one?

"Oh… it seems like it's similar to Bell's" Hestia thought. "It helps him develop at a rapid rate this certainly is an unexpected boon"

So now I was part of the Hestia Familia and thus would be working as a dungeon crawler now.

Christ... I feel like a character in a video game now.

We decided that we would go to the dungeon first thing tomorrow.

The next day

Bell was armed with a knife and some light armor.

" Ah…. Shirou - san… won't you need any equipment?" Bell asked.

"Don't worry… I can handle myself"

Bell was wondering what he would do.

They entered the dungeon and found small monsters as Bell slashed at them. Shirou looked at the monsters and begun learning how they moved and how they attacked. Bell was doing OK as he continued to kill the monsters and collected the stones the monsters dropped when killed.

It was when they got a bit deeper, the 5th floor, when they heard something else

A lot of adventurers begun to run from the dungeon with honest fear

Moooh!

A minotaur has appeared in the upper level.

"Hey… is that supposed to be here?" Shirou asked.

"N...no way… that belongs on the lower floors… this is way too strong" Bell said in fear.

The beast roared once more.

Bell then tried to run away from it.

"Why are you running? Shouldn't we kill it? It would endangered everyone else should it make it outside… come let's lead it away from the exit" Shirou said.

They passed the Minotaur not before slashing it slightly as to make it chase after them.

Both of them begun running as the monster chased after them, until they have reached a dead end.

Just then a fellow adventurer with blonde hair came and sliced the monster arm somewhat, a thin line of blood flew in an arch as the monster furiously turned around.

"Trace...on"

With that two falchion like swords materialized in his hands and plunged deep into the Minotaur's neck… and with a slight flick of his wrist he cut the monster's head off.

As he did that a huge amount of blood splurged from it showering the poor kid in it and then the monster vanished leaving behind a stone that Shirou pocketed.

The helper was a young woman with long blonde hair and white armor, Bell was both smitten and ashamed at his terror stricken face he was showing at her.

"Thanks for giving me that window of opportunity, it would have been harder to do so without some help" Shirou said.

"Ah... no problem… are you two okay?" the girl asked.

"I am fine… but I think my partner is a bit traumatized… can't say I blame him… as we just started today" Shirou said.

Bell took the opportunity to bolt out of there.

"Like a frightened hare" Shirou said as he took out to catch to the scared rabbit.

Guild

"Miss Eina!" Bell yelled as he run through the streets

Eina, a half elf who had pretty face and green eyes smiled until she saw Bell covered and dripping in blood and thus shrieked in fear and dropped many files.

He wanted information on Ainz Wallenstein, the adventurer that helped them.

"Hey… Bell… don't you see you are causing a scene?! Take a shower first!" Shirou said as he caught up with.

Bell went to the a shower as Shirou converted the items into money, the currency was called Vali.

They made a good amount, they could buy ingredients so they could cook at HQ…. But decided to keep saving the money and just buy some meals for themselves… to save up for a small kitchen or the like.

Still as they did so Shirou asked Eina a little bit more about the dungeons and what laid within, with more knowledge of the layout and the type of monsters there he could make it more likely to come back alive with Bell and haul a lot of loot. They went back to their HQ.

Hestia was taken back by the money the two had made…. It was a very good haul for their levels and thus decided to upgrade their stats.

Bell had an unexpected growth on his agility from running away from the Minotaur.

She explained that fighting monsters isn't the only way to gain more status, they also include training and even fleeing.

Shirou nodded and decided to train Bell so he could survive. Bell's skills in combat where non-existent and thus he decided to at least make him more competent and aware of his surroundings.

"Bell, with your current skills… it would be dangerous to go into the dungeon as you are" Shirou said.

Bell clenched his hands but said nothing, it was true… he was very weak.

"That's why you and I are gonna train tomorrow all day, no going to the dungeon at all" Shirou said with a sigh.

Hestia blinked.

The next morning

"Wake up Bell… you too Hestia" Shirou said as he shook the boy.

"yawn….. is too early Shirou" Hestia said.

Bell had a bit of trouble but woke himself up.

They both went to the back of the church where they had plenty of space to train and no one to bother them.

"Okay Bell…. I want you to attack me with the intent to kill" Shirou said.

"S...Shirou isn't that a bit…" Bell said a bit taken back.

"Don't worry… I am going to show you how to fight… and the only way I learned to do so is during combat… so come" Shirou said as he extended his hand and called out to him.

Bell hesitated, he never had attacked anyone just because… there was no reason for going so far.

"If you don't take the initiative… then I guess I should start? You are being disrespectful how you are acting" Shirou said as he vanished.

Bell felt a lot of pain in his chest as he was flung into a wall

*gagh*

"come on… attack… defend yourself, unlike the monsters I am waiting for you to recover" Shirou said.

Bell fell from the wall and eyed Shirou careful and then rushed at him.

With the dagger in his hand he went to slice his torso only for Shirou to grab his wrist and twist his arm and push him against the floor.

"Think Bell…. What can I do to get out… think fast think as if your life depended on it because it will at some point" Shirou said.

Bell twisted his body and managed to free himself, he got close to him and attacked with unrelenting swiftness, however,as in plausible as it seemed, Shirou was redirecting all his strikes with his hands by slapping his arms away from the target area.

"what can I do? This guy… even if he is the same level how is he beating me? I even had my status updated while he refused to do so… so logically speaking I should have the advantage… so how?!" Bell thought to himself.

"The difference between you and me is that I learned to read the flow of battle and change it to my liking, in other words I plan how I will fight and fight in the way that it would be the worst possible way for you… then again is not too hard to do so with you because you have no experience" Shirou said.

Experience…. That's what was lacking! Shirou knew combat well enought to be able to do as he just explained… still that just made more questions pop up… how did he get the experience to do so without the Falna? And what he had been fighting to be able to kill a Minotaur like he did?

"Faster! You have to attack faster but also you got to be precise, all your attacks have to go to their weakest point and deal the most amount of damage possible using the least amount of energy" Shirou said as they continued their one sided fight for half and hour more. After a short break they continued as Bell was slowly but surely learning new things.

Shirou then showed him how to defend.

Grain a small wooden stick he used alteration on it and made it into a boken,then he used reinforcement on it.

Bell swore thay thay wooden sword must had a metal core in it to hurt so much.

He however learned on reading the movement of the weapon to judge where the attack would go and react accordingly.

Hestia was torn… she wanted Bell to be stronger… but this was painful to watch… however the alternative was worst as one single mistake could cost him his life.

"Never go all out on an enemy, gauge their strength and use the minimum amount nesesarily to beat them" Shirou said as he disarmed Bell and slammed him into the ground, however, rather than staying on the ground, Bell rolled away and stood up and ready to attack.

It went on for hours or so until Hestia clapped her hands.

"Okay is time to eat…!" she said as she brought leftovers from yesterday and we ate silently.

"Shirou-kun, you are quite good at combat are you not? Where did you learn?" Hestia asked,curious about her new children.

"Where...you say? I learned on the fly… but I had an instructor who pounder the fundamentals on me… everything else is just years of arduous work to polish myself to this degree" Shirou said.

"Oh … I see, and why did you decide to be an adventurer?" Hestia asked.

"Well being an adventurer would mean I could make a lot of money in order to survive… but also because…. We'll it was a dream of mine when I was a kid… I rather not say" Shirou said as he chuckled awkwardly and scratched his nose.

"I promise not to laugh… I give you my word as a goddess" Hestia said.

"It's a promise I did with my father before he passed away… to become a hero of justice" Shirou said.

"I see… as expected of a child of my Familia, you and Bell-kun will grow strong… stronger and faster than anyone… I can see that you two will reach very far indeed" she said with a kind smile.

The day continued as they both continue to attack and defend… well mostly Bell… but slowly his tracks became more surer, more precise and dropped bit by bit unnecessary movements that he did before. After their training they went to the adventurers showers to freshen up.

Shirou decided to buy a futon he found on the store and rolled on the floor of the hidden room and rested.

The next day

Bell was feeling a LOT of pain that day.

His muscles were screaming bloody murder and so it was a decision that he must rest, so Shirou was the only one who could go to the dungeon.

Taking Bell's bag he went into the dungeon as Hestia went to her part-time job.

After collecting all the stones the monsters dropped he decided to go further into the dungeon and thus reached the 8th floor.

He noticed the intensity of the monsters changing as he went lower into the dungeon as well as different monsters coming at him.

He didn't understood nor cared about it but it seemed that this place actually "Birthed" the monsters.

So this place was a literal goldmine as monster would endlessly spawn and people could make money this way.

After killing a lot of monsters and having his bags filled to the brim with dropped items he made a trek back home, but not without first going to the Guild Exchange, to receive Vali for the items.

All in all… it was a good haul… tomorrow he would take Bell to the dungeon and have him fight the monsters on the 7th level… that would be a good way to train him as well.

The next day.

They all woke up early that day, Bell said his farewell as did Shirou… and Hestia hugged them both very affectionately and wished them good luck as she went to her part-time job.

Both of them managed to make it to the 8th floor of the dungeon and made a lot of progress… Bell was much better at fighting now, far more surer of himself and able to respond better to sudden changes in battle, while far from perfect he was doing great!

"Wow… I never expected to be able to reach this far down… thanks for the lesson Shirou" Bell said.

"No need to thank me… next time we will train on the use of weapons so be ready" Shirou said.

Bell nodded.

They returned and exchanged the items.

As they walked down the street Belk and Shirou felt something odd...

Shirou twisted around and looked towards the direction he sensed the presence and noticed that it was not human… possibly a deity.

Then someone called out to them.

"Excuse me… Mister adventurers…? You dropped this" the young lady said as she handed a small piece of the magic stones tel hey collected.

"Ah. .. thank you very much… I thought we had exchanged them all" Bell said with a smile.

"You are and adventurer right? You heading to the dungeon so early?" the girl asked.

"Heading to the dungeon you say… actually we are going back in again" Bell said with a small chuckle.

Then Bell's stomach begun to growl.

The girl than gave him a small bentou.

"Is not much but…" the girl said with a smile.

"I couldn't though" Bell said bashful "I can't take a lunch from someone I've never met…. Besides isn't this your breakfast?"

"Don't worry about it, there'll be something for me to eat once the pub opens"

"Still…" Bell said

"In exchange… make sure you come eat here tonight!" she said with a kind smile.

"Hooo… aren't you a popular bunny?" Shirou said with a smirk.

Bell glared at him ineffectively as he looked as he was pouting.

The girl giggled at them

"Don't worry… I'll make sure to bring the bunny" Shirou said with a smirk.

After that Shirou and Bell entered the dungeon again… this time making it to the 10th floor, Shirou decided to go for Quality over Quantity and picked only the most complete magic stones he could find as Bell continued to attack on his own.

"Say Shirou… why aren't you attacking anything here?" Bell asked.

"Because you need to get used to fighting while I am already used to it… don't get me wrong I am still learning by watching them attack you, I am learning how they move, how they attack and the like."

"Ah… I see" Bell said as he jumped back to avoid the swiping motion of a kobold.

After he finished he found a drop item from the kobold… a nail.

They continued further down until it was late into the evening.

They made a better haul.

"We could had made more if you decided to help out with the killing of monsters" Bell said.

"And I will… if you are overwhelmed" Shirou said.

They returned to the church where Hestia made another update to Bell's Falna.

His stats had made an incredible jump his speed was at rank B while the rest was at rank C.

Hestia looked pisses at something and then left… she said she had a party with her co-workers.

Shirou sighed, it seems even deities had it rough.

And so Bell and Shirou went to the pub they promised the lady to go.

The place seemed lively and many people of many different races partook of food and drinks.

The Benevolent Mistress was the name of the pub and both entered.

As soon as they got near the door the girl from early in the morning appeared.

"Ah you are the adventurers from the morning, you came" she said in delight

"Yes" Bell said.

"I am sorry… I haven't introduced myself, my name is Syr Flover"

They sat on the bar and ordered food, Shirou was shocked…. The portions were rather… generous. They didn't mind the price as it was well within their price range and begun to eat.

"Not bad… my compliments to the cook" Shirou said.

"Hahaha… thank you… is not often than people praise me" said the burly woman behind the counter.

"Is nice to eat good food made right" Shirou said.

"Well said young un" she said with a smirk.

And both Shirou and Bell begun to talk and discuss how they would continue training him when….

"Nyan, the customers with reservations have arrived!" said a cat girl as a group of adventurers came in.

He sensed it... a Divine entity had entered and with her a large group of people consisting mainly of women and 2 men… and then… she entered.

"Hey… Bell isn't that the girl you asked information about? Ainz something?" Shirou asked.

Bell turned around as to not be seen.

"Ainz, let's tell them all about that thing" said a boisterous wolf man.

"That thing?" Ainz asked

"You know… we let a bunch of minotaur us escape on our way back and you took out the last one on the fifth floor, right?" he said.

"But I…" Ainz said.

Indeed…. It was not Ainz who killed the monster… it was that other guy with the young adventurer.

"and you remember that tomato idiot who was there, right? A wimpy little kid who obviously just started adventuring got cornered by one of the Minotaur that ran from us… when Ainz cut the Minotaur apart it's stinky blood got all over him and he looked like a bright red tomato" he said smiling cruelly. "How pathetic is that?" he said slapping his leg.

Bell shook on his seat in shame and anger.

"Oi… you… how about you shut up since it was your fault this happened? Besides, it was not Ainz who killed the Minotaur… it was me… so stop talking crap about my companion" Shirou said.

"Eh?! You got a problem with how I talk about weaklings? A weakling is a weakling and they should just die… so what's the problem with that?"

"You should have him fixed… maybe it will correct his twisted personality" Shirou said with a deadpan look.

The wolfman's group laughed at this as he snarled.

"You want to be taught a lesson you bastard?" He said with a snarl.

"Bete… calm down… you are making a scene" Ainz said.

"No way…. I am not gonna take crap for. A weakling… I am gonna make sure he understands his position here" Bete said.

"It seems it's true… the dog that barks the loudest seldom bites" Shirou said.

"That's it you punk… you and me… OUTSIDE!" Bete said.

They exited the pub.

"Out isn't that the new child of Hestia? He just became an adventurer a few days ago… he is a level 1"

"He is gonna get destroyed… Bete is on a far higher level than him"

Bell just stood stupefied at what was gonna happen.

"I want you to see how I fight… so you can see how I developed myself to fight" Shirou said.

"Trace… on" Shirou said as the two weapons he used on the Minotaur appeared on his clenched hands.

Bete rushed in.

"I got ya!" he said as he slashed at the open side Shirou had in his defence.

However with a drop of his hand,his blade intercepted Bete's attack and then proceed to attack him with his free hand.

Shirou was exchanging between attack and defence on the fly… goading Bete into attacking the holes he left on purpose.

Shirou wasn't stronger than Bete, nor faster… he was, however guiding the flow of the battle.

Bell now understood it better.

A kick on the face. It broke Bete's nose and begun to bleed.

"You!" he said as he rushed even faster and fiercer.

However Shirou continued to exchange attacks and managed to slice him a bit.

"Enough! Bete stand down. .. this is an order" said a small woman in low cut shorts and with red hair.

This was their Goddess.

"But lady Loki that bastard…." Bete begun to said.

"You would have lost…. I saved your face now apologize and go back to eat and stay silent…. I don't want to be barred from my favorite place" Loki said.

It was then when another cut appeared around his shoulder and on his forehead.

"that young man… he is from Hestia isn't he? He is one you should watch for in the future"

"Chech… he got lucky" Bete said.

"Really? Then how come he has not a single scratch on him?" said his fellow members "also your nose is broken… here let me fix it"

Crack

"Dahhh!"

The rest of the people were clamoring Shirou's victory and were at awe that he managed to pull such an upset… they even bought him a few drinks.

They went back home as Bell tough about the fight and learned something about Shirou.

He used his own body as a trap.

He purposely left himself open to deadly attacks in order to herd the attacks and be able to parry them without the need of looking.

Of course there was no need since you knew what was open or not.

It was reckless and suicidal… yet he made it work.

To be honest Bell envied him… he was the same level as him yet he was able to fight higher tier people.

Hestia would probably not like Shirou's fighting style as she is always asking us to be careful.

Still they managed to get a good amount of loot and went back to their HQ.

They rested well that night.
