Author's Note: Hey everyone, I'm sure you're surprised I'm putting up another Berserk Fanfic, but to be honest, this is a request by a reader called FeralG3. They offered me a chance to test out a concept i wasn't gutsy enough to try (See what i did there) to try. Guts and Charlotte, but with some convincing, and me coming up with proper ideas in which i could use in this fanfiction, with some minor tweaking, I think i can pull this off. However, we made a deal that if this story doesn't get enough views, faves, and positive reviews, this will be a one-shot, but if I can get at least 10 for each category, I will continue this story until the end of the Golden Age Arc, as I can't think of how this story will work out past that point. However, if you any of you can help me figure out how to progress beyond this point, I gladly accept any ideas, anyway enough of my rambling, let's get going into Berserk: The Black Wolf! Catch you on the Flipside! *CLANG*

Chapter 1:

During the battle with Nosferatu Zodd, Guts, growling in anger, his own squad looking in shock as the eyes of the Raid Captain glow with a scars around his eyes gaining the same crimson glow. Guts's mouth contorts into a malicious grin, Casca looking at him in horror as Guts picks up a sword just stands there, a crimson aura flowing off of his body. "Oh?" Zodd asks, "Now isn't this interesting, it has been a long time since I have seen one of your kind, Revenant…"

"Revenant?" Rickert asks, shocked, "What is that?"

"A legendary monster, known to be humans born from the corpses of pregnant women, if any of them survive into adulthood, they are known for being faster and stronger than even the strongest humans, and they grow to be legendary warriors. However, there are only two things that motivate a Revenant into fight, bloodshed and revenge, if what that monster says is true, then Guts must be tapping into his true potential!" Judeau explains, "This is gonna get messy! Casca, get Griffith out of there!"

"Right!" Casca says, beginning to drag Griffith back as Guts laughs and charges forward and begins to swing his blade wildly, snarling like a beast as Nosferatu Zodd blocks each strike, but he notices that his skin is being cut, only shallowly. The sword the struggler is using is dull, which means there is only so much he can do, but each strike brings with it a sensation he craves, pain, proof that he is alive.

"Thats right, struggler! Use that dull blade and continue to fight me!" Zodd shouts, to which he swings his arm, his claws attempting to rake across Guts's chest, only for the berserk man to barely dodge. "So fast! You're much faster than any of your brethren!" Guts then jumps back and raises up one hand, causing his left eye to glow as what appears to be a demon dog's head draws in energy from around him and releases a torrent of slicing winds that rip through stone. Zodd, not having enough time to dodge, crosses his arms, only to have several shallow cuts on his body, but the demon smiles big. Guts falls to his knees, growling, "Ha…. HAHAHAHAHAHA! YES!" Zodd says, laughing, "This is what I have been waiting for, a true battle! However, you only just awoken to your strengths, get stronger, Struggler, and I shall fight you again!" Zodd opens his wings and looks to Griffith, "But I assure you, one day you may very well need to watch your back with that one, who knows, he may lead you to victory or the grave!" He takes off, but Guts raises his hand one last time, the dog head appearing and charging one last blast, only for it to stop short of the flying demon.

"Damn it!" Guts says, coughing up blood and collapsing.

"Guts!" Judeau, Rickert, and Pippin shout, rushing to his side.

"Blood…" Guts says, his eyes still barely glowing as his teeth are now sharp, "Blooood…" His voice is weak, but they can make it out.

"Blood? What is he talking about?" Rickert asks, but then Pippin picks up on of the corpses of the soldiers and a cracked skull, dripping the spilling blood into it, turning the skull into a makeshift bowl. "What are you doing?"

"My father once said something about Revenants, that they were no friends of humanity, but if you aided them in any way, be it giving them blood to drink, or aiding them in finding the obsession of their vengeance, they would spare you, and if you found a Living Revenant, giving them blood would heal their wounds and restore their strength." Pippin explains, "I never once took any account of those tales, but Guts is our comrade, so I am sure the members of his company wouldn't mind giving him their strength after avenging them." He gently lifts up Guts's head and gently lifts the skull to his lips, Casca watching with anger in her eyes, seeing how they are tending to Guts rather than their commander. However as the lifeblood hits Guts's lips, he begins to drink, his eyes slowly opening and he sits up, groaning in pain, his eyes glowing for a second.

"What happened?" Guts asks, then sees Griffith, "Griffith!"

"Get away from him!" Casca shouts, "It's all your fault he is like this!"

Some time later, as the Band of the Hawks return to Windham Castle, Guts is carefully walking through the halls with his crutch, remembering the taste of blood in his mouth. The others had told him of what Zodd had called him when he lost consciousness, and how he subconsciously fought on and pushed Zodd into a corner. 'I'm an Undead, ridiculous! I'm a living being, my heart…!' Guts places a hand against his chest, feeling his heart beating, 'My heart is still beating… But what was it that Zodd said? That when Griffith's dream collapses, that Death will come for me? Tch… I won't let him dictate how I live!' Guts thinks, growling as he passes by a noble, who proceeds to taunt him, but Guts simply plants his crutch into the man's foot. "Sorry, the pain from my injuries threw off the aim of my crutch.

"You cur! Face my blade!" The noble says, growling as he draws his sword, Guts turning to him as his left eye transforms into it's previous lightning bolt shaped form, glowing red with his irritation. The man stops, turning pale and stopping middraw of his sword, before Guts continues on, 'M-monster!' Soon reaching the group, Guts looks to the group with a hint of a smile on his face.

"Hey…" Guts says as Casca glares at him. "How's Griffith?"

"You shouldn't be up yet!" Rickert says.

"Here…" Pippin says, tossing gut a wine skin, to which cut carefully opens it and sniffs it. "It's your new medicine…"

"It's blood…" Guts says, tossing it aside as he puts the cap back in. "Don't need it…"

"Just keep pretending to be human, monster…" Casca says, under her breath, turning her head away.

"Casca…!" Rickert says.

"Well it's the truth, isn't it? Guts is a Revenant! He's a monster, a monster that will kill and eat us if we give him a chance!" Casca says.

"Like I would want to…" Guts says, annoyed with what she is saying.

"Listen Guts, we all know what happened wasn't your fault, she was just worked up as much as we all were." Judeau says, "However, it seems you didn't know you were a Revenant until that fight."

"I was told i was found beneath the corpse of my lynched mother, after that, my adopted mother took me in, but she died to plague when I was 3…" Guts says. "After that I was bathed in bloodshed until now… I know nothing else except for war."

"That doesn't make you any less human, Guts, I've done some reading on what you are, and as long as you feed once a month, you'll be able to keep your instincts in check." Judeau explains. "Not only that, i think you should learn how to harness your abilities, who knows when they will come in handy."

"When I heal up…" Guts says, to which Pippin walks over and offers the wineskin again. Hesitating at first, Guts opens it and gives it another sniff. "What animal did you get this from?"

"A pig…"

"Better than human blood I guess…" Guts says, lifting the skin to his mouth, and as it washes over his tongue, the swordsman's at first repulsed face becomes relaxed and he drinks the whole skin, and gasps for breath once he finishes. Guts then begins to feel his own strength returning, and with a slow movement, settles his broken leg down, and feels the bones reconstructing themselves. "Whoa… I feel different!"

"That's your own physiology…" Judeau says, "You heal much faster than we do, and according to my research, if you take an hour to train with a sword, it will bond to you and will act as an extension of yourself on the battlefield, repairing itself and healing your wounds as it feeds."

"I see…" Guts says, "Interesting…" He then nods and looks to the group, "So whats going on here?"

"Take a look…" Rickert says, "A group of dignitaries and bishops are attempting to vie for Griffith's favor, since up until now, Griffith and the rest of us have had a winning streak going, they want a chance to get favors from him down the road, though some still think of him as an upstart."

"Alright…" Guts says, stepping forward.

""Alright" he says…" Judeau says, smiling.

"Guts hold on! Weren't you listening!?"

"Yeah, so what?"

"WHAT DO YOU MEAN SO WHAT!?" Casca shouts, "We have to wait until the Dignitaries are done!"

"Like I care, I'm just visiting a wounded comrade!" Guts says "Social status means nothing to me!"

"Halt!" The two guards say.

"You shall not pass until the dignitaries have finished…" One of them states.

"Out of the way…" He says, tossing the one of them aside.

"You damned knave!" The second guard shouts, only for him to be tossed aside as well.

"You coming, Rickert?" Guts asks, but then he stops as Casca, punches him in the face, knocking out one of his fangs. "Gck! What the hell, you crazy bitch!?"

"Why does Griffith even bother with you!?" Casca asks, "Why are you always like this!?"

"Tch…" Guts says, snarling as his tooth grows back, "Fine! I'll be back later!" Guts stomps off growling as his eyes begin to glow in front of the Band of the Hawk.

"Damned monster…" Corkus says, glaring at Guts as he leaves.

It's not much later that Guts is standing on a stairwell, and as he feels the wind, he closes his eyes, and begins to fall into his mind, searching deep inside him for that darkest part of him. Through many dark corners and corridors he searches, as if by a maze, and after what feels like hours to him, he finds it, a massive dog shaped monster chained and bound inside him. "There you are…" Guts says, standing perfectly straight, his fingers interlocked, the fingertips aligned with his knuckles, and his thumbs standing up, the tips pressed against one another, his breathing slow as he concentrates.

"Guts…?" Griffith asks, to which Guts opens his eyes quickly and lunges his hand towards the sound of the voice, but stops as he turns. "Oh, you didn't hear me until now?"

"Griffith, don't sneak up on me like that!" Guts says, "I hate it when people do that!"

"My apologies, I was practically screaming your name when i approached, but you seemed to be ignoring me." Griffith explains.

"Oh, sorry about that…" Guts says, to which the two of them begin talking for a short amount of time before the King appears.

"Guts, kneel…" Griffith says, kneeling.

"Huh?" Guts asks, not catching that.

"You cur…! You are before the King, you will show the proper respect!" General Julius shouts at Guts, who simply glares at the General with a menacing smile as he kneels.

"There is no need for you two to kneel, please raise your heads!" The King says, looking at them, "I am merely on a stroll, getting some air."

"Your highness!" General Julius says.

"It is alright, brother, besides, I am pleased to see the White Hawk and the Black Wolf are both recovering from that ferocious battle just prior!" The King says.

"Black Wolf, sire?" Guts asks, remembering his respect."

"Yes, my men who watched you in battle have claimed you fight with the strength of a wolf in battle, and as one knows, the Black animals and white animals are the dominants of the species, and as such, my men have claimed that while the White Hawk is leading the charge with grace and skill, the Black Wolf covers the retreat with sheer ferocity and raw power." The King says, complementing Guts. "And the rumors about you being a Revenant is something that recently peaked my interest…"

Guts audibly gulps at that, and the King just chuckles, "No need to be nervous boy, so long as you don't aim your sword at me, the Church of the Holy See shall not lay a hand on you!" The king explains, "And you, White Hawk, you have lead us to victory after victory, and for that I am truly grateful, to have both of you here puts my mind at ease, and gives me hope that you will bring an end to this war!"

General Julius glares at the two, but the two of them stand and bow their heads, "We won't disappoint you, sire!" Griffith and Guts say at the same time, showing the proper respect for the man. That is when Guts sniffs the air, his enhanced senses turn his head to see a young woman hiding behind a pillar, and Guts is stunned by her beauty.

"Oh, sire, who might that young lady be?"

"My daughter, Charlotte!" The King says, giving her a signal to come forward, but she hides further still, "As you can see, she is my only daughter, I have spoiled her to a degree. Please excuse her, Lord Griffith, Sir Guts!" The King says, walking past them. "Come Charlotte, we are leaving…"

"Coming Father!" She says, as she attempts to keep up with her father, only for a loose tile to catch her shoe and the girl begins to fall. As she does, a had catches her, a strong arm, and Charlotte looks up to see a young man's face, one with short black hair, and dark brown eyes, like that of chocolate, looking at her, concerned.

"Sorry for my rudeness, but are you alright, highness?" Guts asks.

"You Bastard!" General Julius shouts, "How dare you touch the Princess!?" Reaching out to strike guts, only for the young man to look him dead in the eyes, and for his eyes to begin glowing, the Princess seeing this, but the General ignores this warning, and smacks Guts. Griffith, knowing that is a bad move, positions his cane between Guts and the General.

"Pardon my comrade's rudeness, he only sought to protect the princess from a fatal fall, General Julius!" Griffith explains, smiling and giving him a look that gives him a hidden message. The King notices them and is about to say something as Guts helps the princess back onto her feet.

"Charlotte, is something wrong?" The King asks.

"Nothing is wrong, father!" Charlotte says, looking to Guts as she begins to leave. Guts gives her a gentle smile, with a curt bow, and Charlotte gives him a curtsy as she begins to leave, the King notices this and remembers something.

"Sir Guts, Lord Griffith, I wish to speak with you, later, if you wouldn't mind!"

"Yes, sir, just give me the time and place and I shall meet you there!" Guts says, bowing to the King. Once the royal family leaves, Guts turns to Griffith, "What do you think he wishes to speak with us about?"

"I am not sure, but let's get ready for the occasion." Griffith says, to which the two leave, and later that night, the two arrived, dressed in modest finery, and stand before the King on his Throne, the two of them kneeling before him as General Julius watches with irritation in his eyes. "You summoned us, sire?"

"Good of you two to arrive!" The King says, smiling at them. "I actually have a gift i wish to give both of you!" That is when doors open and the servants, pushing in wheeled platforms, holding powerful armors, carefully suited to their style of fighting, with Griffith's being full plate but carefully crafted to be able to allow freedom of movement, whilst being shaped like that of a humanoid hawk, with feathery flourishes on the shoulders and helm, but everything else is suited for combat, and armed with a saber that is opulent but powerful. The other is a heavy and monstrous armor shaped like that of a wolf-like monster, whilst bearing a heavier blade than guts is used to. "I had these both forged by a powerful sword smith named Godo, in which I had specified they both be a perfect balance between beauty and efficiency. Lord Griffith, this is the Gryphon Armor, may it serve you well, and for you Sir Guts, the Werewolf Armor, with a powerful sword called Durandal, the strongest sword in the Kingdom, aside from his absurd blade."

"Absurd blade, sire?" Guts asks.

"Yes, he has a sword that he claims could kill a dragon, but it is too large and heavy for any man to wield, however, I had this smaller, more manageable incarnation made for you." The King says.

"May I, highness?" Guts asks, to which he gives a gesture of permission, and as guts picks it up, he feels the weight of the weapon, unlike the sword he currently wields. "Amazing… I can actually feel the weight of this thing!"

"Simply incredible, that weapon weighs over a hundred pounds, and yet you are capable of picking it up with little to no trouble!" The King says. "May these weapons and armors serve you well in the future!"

"Thank you, sire!" Guts and Griffith say, to which they leave whilst the armors are brought to their quarters. Time passes and during the Autumn Hunt, Guts aids the hunters in getting their catch, whilst Griffith chats with the Princess, however, as he returns, Guts notices something on the hill with the two.

"GRIFFITH, PRINCESS, BEHIND YOU!" Guts shouts, to which they turn around as a boar passes by them, scaring Charlotte's horse into a panic. Deep inside him, something within Guts snaps, and he charges after her with Griffith, both of them moving quickly and swiftly catching up with the Princess. As the young woman begins to fall as Griffith calms the beast, Guts catches her, "Are you alright, Princess?" Guts asks.

"Y-yes, Sir Guts, thank you, both of you!" She says, her heart pounding.

"It's no trouble, just doing our job." Guts says, lifting her back onto the horse. "Are you feeling alright?"

"Yes, my heart is still pounding but I was terrified I would die!"

"Then let me give you some advice!" Guts says, and begins to instruct her on what it's like to ride a horse at high speed, and helps her calm an excited or scared horse. "Use this advice and next time you won't fall off, and you can even direct your horse during it's charge."

"Y-yes, thank you, Sir Guts!" Charlotte says, a light blush on her cheeks. Guts grins at how cute she is, but then he sniffs something. "GRIFFITH!" Guts shouts, too late, only for a bolt to pin itself in his chestplate, with the Band of the Hawk approaching, Casca rushing over as everyone gathers, only for Griffith to stand up, and pull out the arrow. "Are you alright?"

"Yes, but I can see this is a poisoned arrow, somebody attempted to assassinate me? Guts, what does your nose detect?"

"I caught a whiff of that poison just before it flew, but now I can't trace it!" Guts says, growling as his eyes glow. "Dammit!"

"It's alright…" Griffith says, turning his eyes to glare at a noble, but then looks at the arrow again, "This is no ordinary poison… I think I can have somebody track it down. I'll need to see you later, Guts…"

"Right…" Guts says, his feeling a pain in his fangs, wanting to sink them deep into the man responsible for all this. Casca notices the look on his face and sees Guts's lips curled back in anger as his fangs begin to become visible. This startles her slightly, Guts is angry, and she knows from what was told, when a Revenant gets angry, they become hungry.

"Sir Guts…" Charlotte says, snapping him out of his rage, the young man turning his head towards her, only to find her sticking her finger in his mouth. Everyone looks in shock as Guts's eyes go wide as he tastes something on his tongue. Backing off quickly, rubs the back of his hand on his lips and sees blood, and notices the young woman's hand is bleeding from gripping the reins too tightly. "I thought you might need something to calm you…"

"Th-thank you, highness…" Guts says, stuttering. The King had noticed this and when they arrive with the royal doctor, the Princess explains what happened and says that before Guts went on a rampage, she gave him some of her blood to calm him.

"I did some reading, a few days ago, and it seems Revenants can be calmed if given blood to clear their heads." Charlotte explains.

"A wise decision, if a bit inappropriate…" The King says, looking to Guts, who lowers his head in shame. "Still, it is better than allowing a Revenant to go on an indiscriminate rampage trying to avenge his master."

"My apologies, sire…" Guts says.

"Tis no trouble, Sir Guts, you were only doing what comes naturally for you, I will overlook this just once."

"Your mercy is greatly appreciated, your highness!" Griffith says, hiding the bolt. Later that night, the Princess looks out the window, watching the full moon rise, and as she looks out, she can swear she hears the howl of a wolf in the distance, and she is tempted to make the call back. To this, she looks at the bandages on her hand, and smiles as she had calmed down the Black Wolf with her blood, and thinks of him. As she enters her bed, she dreams of him, protecting her, and her heart flutters. Guts, on the other hand, stares at the moon, the taste of the Princess's blood still in his mouth, and the scent of her skin stuck in his nose. Her scent was like of roses, whilst her blood tasted better than the finest wine he could remember tasting, and in the back of his mind, he finds himself thinking of the Princess, wanting to end this war for her.

'I swear, if anyone dares lay a hand on you, I will tear them to bloody pieces!' Guts thinks, 'Until then, my sword belongs to Griffith…'

Author's Note: Phew, to think I managed to get this done through the span of an entire day. Honestly, I didn't want to do this one, but it was a concept that was just too tempting to pass up. I'm not ashamed if this story becomes a One-Shot, at least i got the request out of the way and done with. Everyone I will be getting back to MHA: Life Foundation soon, i just need the inspiration to hit me so I can properly put out a chapter, so don't worry, I haven't abandoned it. As for this story, this is the Prologue/One-Shot chapter, but if I manage to get a good number of faves, follows, and good reviews, I will continue this. I am not sure what I will do after the Golden Age Arc, but if you guys can come up with ideas to help me, I'll try to go further than that. However, I need your help figuring out one thing, how in hell does Casca have her Demon Child in this story? This is a Guts x Charlotte fanfic, and so I can't figure it out, do I make the Demon Child Griffith's Son? What do I do? If you have any ideas, I am willing to listen. Anyway thats it for this One-Shot/Prologue! I'll catch you guys either in Ballad of the Goblin Slayer, Child of Darkness, or Life Foundation, catch you on the flip side! *CLANG*
