Summary: "He wasn't wrong." Archer isn't a hero. He didn't want to be one at all. But when the fate of humanity hangs in balance, what is a Counter Guardian to do?

Chapter [5]: Heart On Fire

"Every damn time!" Archer screamed even as he backtracked from a fast but sloppy strike of Beowulf.

"Archer…" Ozpin tried to calm the white-haired man to no avail.

"No, shut it!" Archer seemed to pour his frustration into his black bow, crushing the wolf like creature with the improvised melee weapon.

"Every time these idiots get involved, it seems to be my job to rescue them." Angrily Archer pointed at team RWBY and JNPR.

Team CRDL seemed to try their best to spontaneously develop camouflaging semblances. Professor Goodwitch glare more than made it clear that they failed.

Ozpin calmly listened the man berate him, idly wondering whether Archer was really as oblivious to the coming Nevermore and whether to intervene himself or leave it to Qrow.

Qrow seemed more interested in his flask of Vale's finest. Typical.

In lieu of defending, Archer raised a hand causing a blade to come screeching through the Nevermore.

For its part, the Nevermore took a mere second to notice the lack of its brain before it dispersed into Grimm ash.

"One more time." Archer swore aloud even as Hrunting was altered under the phenomenal strength of his magecraft into a projectile even as the horde of Grimm approached them.

"Test me one more damn time! I dare you!"

Archer fired.

The Noble Phantasm blurred.

"Well if that wasn't something." It just wasn't his day, Archer swore to himself.

First, Team CRDL thought picking on Jaune Arc of all people was a great idea.

Then, Team RWBY and rest of Jaune's teammates got involved.

Finally, the fight happened in middle of the damn Forever Fall, a place famous for its Grimm and Grimm attracting syrup.

It had been like playing firecracker in middle of an oil refinery.

No wonder, Ozpin himself had to come.

"Not like the bastard did anything." Archer swore internally.

Oh, Archer knew that Ozpin was skilled but Archer doubted that army slayer had been much of a specialisation in existence.

No wonder Alaya had been so interested in Emiya Shirou.

Take away his prana limitations and his Reality Marble was an ideal army destroyer.

And to top it off…

"What do you want, Winter?" Archer said.

In Archer's opinion, Winter Schnee was the incarnation of the concept "Spoiled" like Archer was the incarnation of "Sword".

Arrogant, conceited and worst of all, her condescending narcissism.

If only she had world destroying powers, Archer would wonder if Gilgamesh had come back.

"Why, Archer? Can I not come to simply meet my sister?" Winter said and Archer could feel his heckles rise. That was fairly polite by human standards. By Winter's standards, it was pretty much equal to grovelling before him.

She needed something. Bad.

"In less than a month since she had been here?" Ozpin thankfully was similarly quick on uptake.

Winter seemed momentarily startled before replying, "Now that you ask, I did have something to consult Archer on…"

"No." Archer didn't even bother listening before leaving.

….

"And if that isn't the worst way to getting rejected." Qrow took another sip from his flask.

Nobody replied.

It took ten minutes for Winter's patience to snap like a twig.

"You douchebag! You wouldn't even listen to me!" The rest of the Beacon's population seemed to watch but Archer ignored them just like he ignored the Atlas harpy.

"As if there is anything worth listening." Archer muttered, annoyed.

Winter latched onto it.

"What did you say?" Any lesser men would have frozen at the ice like chips that were here eyes. Archer didn't even bother raising an eyebrow.

"You are going to do what you always do. Read some act about humanity, Grimm, some supposed duty to save the world and it will end up with you trying to get me to join that damn Atlas slavery contract for research purposes."

"It is for good of humanity!"

"Oh, there we go again." Archer kept moving.

"Can't you put aside your ego aside for sake of saving the world for one second?!" She was practically shouting by now.

Archer stopped, patience snapped.

"But it isn't about saving the world, is it?" He faced her and looked her into the eyes.

Winter was shocked at finally having Archer's full attention. She had been trying for years to get it that she had no idea what to do, now that she had it.

"What do you mean?"

"It is about saving Atlas, not the world."

"No, it isn't!" Winter refuted vehemently.

Archer looked at her, wondering whether to be angry at her obnoxiousness or be pitiful.

So, he said only one word.

"Penny."

Winter seemed to take a moment to wonder what he was trying to say before it made sense.

Eyes widening, she dragged Archer into a nearby confined Janitor's room.

"How do you know about that?!" Winter whispered angrily.

"Implantation of a soul? What's there to know about it?" Archer wouldn't admit it but he was enjoying this game of theirs.

"It is supposed to be top secret!" Winter refuted.

"It is supposed to save the world as well. Yet, why only Atlas seems to have retained the information?" Archer accused rather blatantly.

Winter took a moment wondering how things had degraded so quickly.

"Because Penny is dying. The project failed."

That caused Archer to stop in his footsteps.

"Dying?! You succeeded in implantation?!" Archer shouted.

To understand Archer's shock, it is necessary to understand the nature of Aura. Aura was a part of soul, a bleed off of the soul's infinite power. To transfer aura was to transfer soul…

Heaven's Feel, The Magic of Soul.

But this world has nothing even close to that scale!

If Atlas controlled even a fraction of that, they would have conquered the world/destroyed Grimm within days…...!

"Yeah, we found a semblance. A girl named Miyu Emiya…."

The rest of the world seemed to stop as the accursed Emiya name resonated in an empty wasteland filled with sword.

During his existence as a Counter Guardian, there had only been one Miyu remotely capable of a True Magic.

The Children Of God

For her to take, the forsaken name….

This changed things. A child of god was akin to a walking, alive Holy Grail. Anyone short of Alaya/Gaia themselves couldn't be allowed control of something of that magnitude for even the smallest instance of time.

"Hey are you listening to me?" Winter snapping her fingers in front of him brought him out of his thinking.

"You were telling me about Miyu?" Archer said.

Winter seemed sceptical for a moment before explaining that she didn't know much about Miyu but if he wanted, he could ask Miyu herself as she was with Winter on the ship.

Archer agreed.

Archer traced Kanshou moments after ditching winter somehow.

And so, I walk this path again.

It was cruel but A Child of God couldn't simply be allowed to walk this world. Nor could it be allowed to perpetuate the accursed Emiya legacy. Too much blood had already been shed by Emiya family.

She is innocent. A voice suspiciously like Shirou Emiya said in his mind.

So is this world. Archer said.

Sacrifice one to save a hundred?

Then what was one life to save a world?

Then why does Kanshou feels so heavy. Shirou's voice was neutral but even his blades couldn't have cut Archer so deep.

The Noble Phantasm in his hand seemed to weigh like the Skies that had weighed on the shoulders of the giant Atlas.

Why does life have to be so cruel? Perhaps Archer thought, he had really gone insane, Shirou Emiya pitying him? Was it perhaps some twisted form of self-pity?

Or perhaps the world is the one twisted.

And so, as Archer moved towards where Miyu's room should be, he never noticed the moisture dripping from his eyes.

All he could feel was the heavy, cold handle of Kanshou.

A part of him wished she was sleeping. A part of him begged.

He didn't think he had the strength to look in the eyes of yet another innocent as life drained away from them.

The fate like always held no pity for him.

She looks like Illya.

And if that wasn't his biggest mistake. He had been weak, slow and simply not been enough to save his sister.

Perhaps Illya's death had simply been the catalyst. The spark of mistake that had ignited the chains that ended up damning so many…

She was so young.

And the price that humanity's survival had never run higher.

He raised the blade….

"Onii-chan!"

And the fates shattered.

Important announcement

This story will be on a one-month hiatus while I work on my new Worm story A Will To Shatter Stars(my personal favourite)

and

DxD Xover Hold The Heavens

This chapter was intentionally short. I had almost abandoned this story due to Writer's Block. I have admittedly lost interest in RWBY due to its shitty cannon but I will finish this story probably by Christmas.
Expect new update by Early November. I will probably figure out the plot by then and the ending.
