Chapter 1

A/N: I know, I know, another story. And this one has been brewing in my head ever since I got my hands on the game Sekiro when it first came out. And I will be continuing the other stories I have with the best of my ability. And honestly, this was fun to work on and I hope you guys will enjoy this. As always, criticism is welcomed.

"DO IT!"

A silent grunt of confirmation came from Sekiro as he held the Mortal Blade above him as he gazed down at his defeated foe, the legendary Sword Saint, Isshin Ashina. After a long and arduous battle, he had won against such a fierce opponent. And now the aged samurai awaited his coming death from the one-armed shinobi.

With no hesitation, Sekiro brought down the Mortal Blade, cleaving away at Isshin Ashina. A crimson spray erupted from him as the old samurai couldn't help but be impressed at his opponent in his final moments.

"Well done… Sekiro…" Isshin Ashina croaked out at him, falling forward, laying silent in the Moonlit Field.

"… Farewell," Sekiro uttered softly as he flicked the Mortal Blade down and slowly sheathed it back into the weathered red scabbard.

This truly was the greatest battle he had ever fought, all to save and serve his master. All the lives he had taken, the battles waged, and insurmountable obstacles overcome, Sekiro had come far. He was victorious in the face of death, many times, over and over again.

Though he had no time to celebrate with what he had accomplished. He still had something to do. The journey itself was nearly at a close now. All that was needed now was the last step to have it be completed; the severance of immortality for the Divine Heir.

He scanned the Moonlit Field, searching for his young master. The moment he located him, he ran over to him and knelt down beside him. He was wounded by Lord Genichiro Ashina prior to the battle, but he was still alive, just clinging on.

"Wolf… Where are you?" The Divine Heir, Lord Kuro, rasped out as he tried to look for his faithful shinobi.

Sekiro sighed softly as he reached down with his right arm, placing his hand on Kuro's back, and gently brought his lord up. "I am at your side," He told him trying to bring his lord reassurance.

But he knew those words would do little knowing what his lord wanted in the end for the severance of immortality… The Divine Heir must die at the hands of their servant.

And the thought alone horrified Sekiro when he learned this from Lady Emma early on. The code he was raised up by, the Shinobi Iron Code, dictated that he must protect his master no matter what. And if his master was taken, to bring him back at any cost.

Though it was a code he had chosen to break. First to his foster father. And now, to his young lord, to preserve his life. He had died countless times already to save him. Many more times when he sought out the tears of the Divine Dragon and another little item that would ensure his lord would live.

Another death would be no different than all the others.

Looking down into his left hand, he saw the tears of the Divine Dragon and the petals of the Everblossom Tree coalescing together, knowing that the choice he was making would be the point of no return.

As he looked at the face of his young lord, he could hear the voice of Lady Emma repeating what she told him about having Kuro live instead.

"Those made immortal by the Oath of the Dragon's Heritage shackles their masters."

This he knew all too well ever since he awoke back in the Dilapidated Temple when he lost his left arm. But the next did bring a small chill up his spine if he was being honest to himself.

"The oathbound of the Dragon's Heritage must die."

But despite all of this echoing in his thoughts, he soon recalled what he said to his foster father back in Ashina Castle.

"A code must be determined by the individual… This is what I've decided."

Sekiro nodded to himself as he knew what he must do now as he brought his left hand over to Kuro's face. "Take the Dragon Tears," He said softly as he poured it over the young lord's face.

Kuro opened his eyes as he looked his loyal shinobi, grunting softly in pain from his wound. But before he could speak, he drifted to sleep against Sekiro none the wiser.

The Wolf could only nod in affirmation seeing that his lord had fallen asleep. He gently placed him back down on the ground before reaching up with his right hand and gripped the handle of the Mortal Blade.

"The final step," Sekiro thought to himself as he drew the infamous odachi from it's sheathe. He brought it in front of his face, his eyes gazing upon the crimson hue of the Mortal Blade. His grip tightened on the handle as he nodded.

"I hereby condemn the last Immortal," He declared and placed his fake hand on it, the blade now positioned against his neck. His heart hammered within his chest as he glanced down at his young lord. And for the first time in a long time, a small smile tugged at his lips.

"May you live on, and embrace what it means to be human," He softly uttered to his master. He slowly raised his head back up with his eyes now closing. He knew what needed to be done now as he let in one last deep breath. "Farewell… my friend."

His hands gripped the handle tightly and with the last vestiges of hesitation gone, he swung the blade towards his neck. A loud slash echoed through the air with a flurry of Sakura petals appearing into the air. Sekiro's now headless body still remained on its knees in its final seconds of protecting his lord before it fell forward.

His duty is now complete, for his lord was now rendered mortal, freed from the curse of immortality. And Lord Kuro would live his life like any mortal man, with the memory of his shinobi living on even in death.

For his story in Japan was over.

Yet his story would continue elsewhere, where a man of his caliber was needed. In a world where the moon was shattered, but hope still held strong in the hearts of the courageous.

The afterlife was where Sekiro thought he would make his final journey to. Regardless if he was to be welcomed by his ancestors or dragged to the depths of Yomi, he knew that what he had done, he had no regrets.

But instead of feeling the supposedly cold grasp of a true death, he still felt warmth in his body. Confusion began to flood his mind as he could feel his back resting against something soft. It felt like that he had been asleep for far too long and that he should be getting up by now.

And woke up he did as he slowly pried his eyes open. His vision was blurry as it was met by the harsh sting of light shining in from a nearby window as he found himself laid on something soft. Sekiro blinked a few times to clear up his vision as his eyes focused on the ceiling. "Where… Where am I… At the temple? No… I shouldn't be…"

And what served to shock him some more was when he felt it… His left arm. He could feel it, his fingers moving at his command as he tried to see if this was a trick. It was no trick at all as he clenched his left hand into a fist. "Impossible… Genichiro cut my arm off… I took my own head…"

His ears twitched when he heard what seemed to be a door sliding open but felt too weak to react. Sekiro then heard a gasp with footsteps that came closer. "Ah, you're finally awake," A man's voice said.

Mustering what strength he had, Sekiro slowly moved his head to the side and blinked a couple times to clear his vision up some more. His eyes fell upon a beast of a man, as large as or maybe larger than most samurai leaders he crossed blades with. A beard sat on his face with black hair slightly long with yellow eyes that observed the Shinobi.

Sekiro tried to sit up, only to groan in pain as his body hurt all over. The man rushed over and stood at the side of the bed he was laying in. "Easy now, you shouldn't push yourself," The man told him.

"W-Where… Where am I?" Sekiro muttered out to him, only to be more confused as his voice sounded… Younger?

The man smiled as he nodded at him. "Do not fret, young man. You are in my home in Menagerie," He responded to him.

"Menagerie… I've never heard of that place before… Not even Father mentioned such a place…" His guard was up now but he didn't want to do anything rash. That was not the Shinobi way.

"And you're quite the lucky one too. My men have found you washed ashore on the beach three days ago and brought you to my home. And thanks to my wife, she convinced me to have you taken care of and nursed back to health," The man told him which made Sekiro widen his eyes.

"Three… Three days…" It wouldn't be the first time he had been incapacitated for a long amount of time. Death was an acquaintance he wasn't unfamiliar with.

"And they found this near you before they brought you over," The man mentioned as he reached down below the bed confusing Sekiro. And his eyes widened when he saw what was in the hands of the man. A sword he knew all too well as the man presented it to him. "Does this belong to you?"

Sekiro was silent with his eyes glued to the sword. The same sword his Lord… Former Lord Kuro gave him. It was at his side at all times, his constant companion through blood and tears, through those that opposed him, and preserved his life. "K-Kusabimaru…" He looked at the man and nodded. "Yes… It does."

The man smiled hearing this and nodded before gasping. "Oh, how rude of me. I haven't introduced myself yet to you, young man. Ghira Belladonna, at your service, Mr…" The man, now known as Ghira, said as he still didn't know the name of the Shinboi.

Sekiro was unsure of what to say as his teachings as a shinobi went through his head. Why would he tell him anything? But then his words that he told his father back in Ashina Castle echoed through his head. "A code must be determined by the individual… This is what I've decided."

And seeing how he had his left arm back, in a place he was unfamiliar with, and even felt even younger as there was a mirror behind Ghira to which he saw his own face. It looked like he was quite younger, probably a few years after he had been taken in by Owl to be trained in the shinobi arts.

"Is… Is this the doing of Buddha?" He thought at first as the Sculptor back in the Dilapidated Temple came to mind. "Perhaps…. Buddha gave me a boon… A chance to… To live my life…"

A moment had passed before he came to the ultimate decision as he nodded at Ghira. "… Sekiro… My name is Sekiro. And… And I'm forever in your debt."

"Please, you don't own me a thing, Sekiro. It would've been wrong of me not to help someone in need," Ghira told him.

Sekiro was about to respond before something interrupted them… The growling of his stomach. He was hungry. A flustered look appeared on his face being embarrassed how his stomach had rumbled so loudly. And Ghira ended up laughing heartily and nodded. "Ah, you must be starving after sleeping for so long! Well good thing its lunch right now. My wife should be done cooking."

Sekiro nodded as he was honestly hungry with his gut rumbling again. "Yes… I think food would be good…" He said softly.

Ghira laughed once again and smiled warmly at Sekiro. "Well then I'll be sure to let Kali know to bring some food over and-"

"No… I do not wish to linger in bed any longer… I need to start moving around again," Sekiro interjected to Ghira.

This took Ghira by surprise but he saw the intent in his eyes. He was going to get up whether he said no or yes. So he sighed softly but nodded at him. "Very well. Let me help you get up then."

Sekiro nodded as he managed to push the blanket off of himself as he inspected his body. He was smaller than he initially was, and his left arm was indeed there, not gone. Even with how sore he felt, he pushed himself to sit up and swung his legs over the edge of the bed. And taking a deep breath, he pushed himself off the bed, getting up on wobbly legs and unsteady legs.

And Sekiro took his first step in the world of Remnant.
