I was inspired by ScarecrowGhostX to try my own hand at writing One-Shots. I felt Black Clover has lots of awesome characters and potential to work with. I also felt it was appropriate because Black Clover is somewhat of a sister series to MHA in the same way Naruto and One Piece are to each other.
Anyways here's the first chapter, It does have borderline smut due to a hot spring scene, so Enjoy and tell me what you think!
Special thanks to ScarecrowGhostX for the inspiration and Asdf0789 for reading over it.
"….Are you really sure you want to fight my elder sister?"
"Yeah, I'm certain of it, Fuegoleon! If I'm going to be the Wizard King, I have to honor any and all challenges!" Asta said, waving a red envelope in his hand.
Leopold and Fuegoleon stared at each other in a shared unease. In the background, Theresa was lightly chuckling at the current scene unfolding.
Asta the star and now captain of the Black Bulls, and renowned hero to multiple kingdoms and territories had suddenly barged in their home unannounced.
Apparently, the eldest sister, Mereoleona, had issued a letter of challenge. Yet she forgot to note where to find her.
In hindsight, Fuegoleon shouldn't've been surprised. His sister had claimed him as her 'prey' for years now, like the wild animal she was.
And like all predators, they knew when it was the perfect time to strike.
What had Fuegoleon concerned was the fact that Asta had a very real chance of coming out on top. Sure, he learned to never bet against his older sister who he deemed 'The strongest,' but let it not be said he wasn't worried about the consequences should she be defeated by anyone other than himself or Leopold.
Speaking of, it seemed that his younger brother had reached the same conclusion.
"It's not that I don't support it—I'm ready to throw down anytime, anywhere, anyplace. Just….does it have to be her?" Leo said though Fuegoleon did note the timbre of nervousness in his voice.
Asta tilted his head in confusion. "….I don't understand? She challenged me. So, I have to take her up!"
Fuegoleon was about to interject when Theresa spoke up instead.
"Let him go off and do what he needs to do. Some lessons are better learned personally than taught verbally."
Fuegoleon closed his mouth, conceding the point with a sigh.
"….Fine," he said after a second to process what was about to happen. "You can find my sister on the Ultima-Volcano Mountain Trail."
"Wait," Asta said, holding up a hand. "You mean that same place she always drags us for training?"
Leo crossed his arms and nodded. "The one and only. Big sis loves it there."
"I guess fire and lava is her natural element…Makes sense." Asta then turned on his heel and ran to the door. "Thanks for everything guys!" he cried as he burst through the door once more.
Theresa was still cackling as the door had yet to settle back into place.
"That boy has no idea what he's getting himself into."
Leo elbowed the frowning Fuegoleon. "Hey, look on the bright side. If Asta wins, we'll have the ability to fight him any time we want." The younger brother then began to laugh boisterously while claiming Asta as his rival once more.
Fuegoleon shook his head and pinched the bridge of his nose. "That's not exactly what I'm worried about."
In his head, a certain scene from his childhood played out on repeat. Oh, dear. Maybe with age came wisdom.
Knowing Mereoleona?
Unlikely.
Once again Fuegoleon sighed. He then walked off towards his office, leaving the laughing duo of his younger brother and his former mentor behind.
Someone would need to have the paperwork prepared should Asta return victorious. Also, he needed to prepare himself for Yami's inevitable antics no matter the outcome.
Even though Yami was no longer a captain and he himself had passed the position to Leopold, the man still had a habit of making a nuisance of himself.
—X—
Asta hopped off the Demon Slayer sword and onto the heated rock of the volcanic trail. One of the few islands in a sea of variable fire—Not counting the volcano of course.
It hadn't taken him too long to get there from the Vermillion estate. But long enough to vaguely ponder what Fuegoleon and Leo were being cryptic about. To him, a challenge was a challenge. Mereoleona loved to fight and so did he!
Asta shoved those thoughts aside as he took in the atmosphere of the unique environment.
The all-too-familiar smell of sulfur and brimstone hit his nose as he gazed around in awe.
Liebe popped into existence on Asta's shoulder.
"I'll never get tired of this place; we trained here so hard back when the Midnight Sun was running around." Asta mused to Liebe as he slung the massive zanbato over his other shoulder.
"Yeah, it's where you first started tapping into my power consciously," Liebe replied.
"Exactly Mereoleona threw some serious trainin' at us." He pointed to the entrance to the nearby caverns. "Like those caves!" He pointed to a giant fireball hurtling in his direction. "And that giant fireball coming right towards us." He next pointed to a volcanic vent. "And not breathing in the poisonous gas!"
Liebe frowned in visibly stunned fear at him and popped from existence back in his grimoire.
Asta was stunned for a second until his brain processed what he said.
"Giant fireball headed right for me?!"
Asta by instinct swung his sword by the flat of its blade sending the fireball back.
Unfortunately, it collided with a second fireball resulting in both fizzling out.
It also revealed a whole barrage of fiery projectiles headed Asta's way.
Asta screamed as he frantically dodged, slashed, and parried as seemingly the whole island he was on was rained in hot fire like arrows on a foreign army.
"What is going on!" He yelled.
Far away on top of the volcano, a familiar voice started laughing maniacally.
"WAHAHAHAHA! LITTLE FOOL! THE MOMENT YOU STEPPED INTO THIS PLACE; THE FIGHT BEGAN. THIS TIME WE FIGHT FOR REAL. DO NOT HOLD BACK, I EXPECT MY PREY TO BE STRONG. GIVE ME THE FIGHT I'VE BEEN WAITING MY LIFE FOR!"
Her already loud voice was enhanced by magic; it was impossible not to hear her.
Batting away the last of the fireballs, Asta finally saw the person he came for.
Mereoleona was standing on the lip of the volcano's crater high above him. Her short hair was blowing in the wind, her hand was clenched in front of her, and her chest was puffed out proudly. She wore the feral grin of a predator Asta had learned to associate with her and only her.
She ripped off her squad cape and threw it to the wind, exposing the sleeveless white tunic underneath. She then waved her hand in a taunting 'c'mon' gesture.
Asta smirked at her in return.
"You want a fight?! Well, you got it! Don't come crying to me when I come out on top!"
Touching his sword with both hands Anti-Magic flowed through his body.
In no time flat his hair was black with horns and his entire body was covered in jet-black armor. Black-Asta: A form whose name was ironically given by Mereoleona's younger brother Leo.
Using his Anti-Magic, he flew through the air, black lightning rolling off his body as went.
In no time flat he cleared the distance up the volcano and swung his sword at Mereoleona who was grinning even wider than before.
"Calidus Brachium!"
A giant lion's paw made of fire collided with the Demon Slayer sword. Despite its innate properties, it was only slowly moving through and dispelled the magic. To Asta, it felt like trying to move through Jello. Her mana was that dense. By the time he cut through, she had already leapt out of the way.
"I refuse to be left behind by you!"
Shouting the name of her magic to the heavens once more, a whole flurry of fists descended on Asta, knocking him back.
The attack hardly scuffed his armor, but it did stun him, leaving him open for a punch to the face, courtesy of Mereoleona in her hellfire incarnate mode.
The former squad leader of the Crimson Lion-Kings remained floating in the air with a cocky smirk on her face and her arms crossed as she watched Asta recover from the blow.
"Wow, you really are serious about this!" Asta exclaimed, rubbing the bruise on his cheek.
He looked her up and down. Asta had always thought that Yuno was his opposite but seeing her, maybe he was wrong.
Mereoleona wasn't just blessed with magic like Yuno was, but she turned her body into pure magic in comparison to his Anti-magic. Combined with her fire magic….
Mereoleona was quite literally the light to his darkness.
Upon seeing him stare at her, the woman's lips turned up into a smile. Unlike her usual feral versions, this one has something else to it. Something he wasn't able to immediately place.
Mereoleona laughed at his confusion and started to speak.
"Lionesses are always serious when it comes to the hunt." Mereoleona's voice then took an unknown edge to it. "Especially when it comes to the strongest male possible!"
Warning bells went off in his head, and he could also sense Liebe's uneasiness at the last part of her statement. Asta chalked it up to her ki as he dispelled the Demon Slayer sword and brought out the Demon Slasher katana.
Asta took a deep breath and raised his sword above his head, clasping the hilt in both hands. "Alright then, no holding back. Out of everyone I've met, you deserve that honor. It would be disrespectful to not give it everything I've got!"
"Bring it!"
"Calidus Brachium—Purgatory!"
Mereoleona's body turned from an infernal yellow and orange to a blazing blue. Even sparks of white were starting to flicker along her body.
A brilliant beautiful blue flame began to expand from Mereoleona's body as a result of her taking hold of the surrounding mana.
Sweat fell along Asta's face as he felt the sheer heat of her attack enveloping the entire area around him. If he wasn't wearing his Anti-Magic armor, he would have surely been cooked by this point.
He channeled his Anti-Magic into the blade and with a yell, slashed downward.
FWOOOSH
A jet-black wave came from the sword and cleaved her mana zone in two. His version of Yami's Dimension Slash.
The confident smile on her face quickly turned into an expression of surprise as she was rendered defenseless, and her body went from blue and white back to yellow and orange.
Asta didn't waste the chance as he locked on to her mana and rocketed right towards her, smacking her in the stomach with the flat of his blade.
The older woman was sent somersaulting through the air across the volcano.
He gave her no chance to recover and dictate the pace as he brought the Demon Dweller sword out and rapidly fired Anti-Magic beams to cover his approach.
Once he got to Mereoleona, he slashed at her with the Dweller sword. To his surprise, he went right through her and bisected her in two!
Asta's eyes widened as he watched her upper and lower half reconnect.
Mereoleona let out an unrepentant laugh as she righted herself in the air and faced him.
"A neat little benefit I learned about this form is that being made of magic means that even if you slice me to pieces, I can just come right back for more. Unless you erase my magic completely it'll never end!"
"Then the mana zone on top of that only adds to our troubles!" Liebe pointed out inside Asta's mind. "Captain Yami was right. This woman really is a wild animal on the loose!"
"Animal or not, I'm still gonna win and prove I'm the top dog worthy of being Wizard King!" Asta said forgetting Liebe had replied in his mind.
"Hell yeah, that's the spirit! Some would call you a beast of a man yourself. Time to prove who the top predator really is!" Mereoleona yelled back, charging at him.
Asta raised his swords in defense, expecting an attack from anywhere. His eyes widened as Mereoleona continued to charge in and started to throw out plain jabs and haymakers. No paws or tricks, only pure prizefighting.
Asta was forced on the defensive under her assault. Every time her hand hit one of his swords it dissipated. She didn't care; it returned to shape the very next moment.
"You sword types are all the same!" She roared, between blows. "You suck at infighting. You most of all. Those big swords mean nothing if you can't use them!"
Asta felt his anger rise in challenge, and Liebe nodded in agreement.
He dropped both swords, allowing them to disappear back into his grimoire.
"Haha! Finally surren—"
Her taunt was interrupted by a punch to the face. And then another to the gut. He attempted another to her face, but she stopped it using her own hand.
Wordlessly she smiled and threw her own punch. Asta was happy to reply in turn. The two then started to brawl in mid-air over the volcano.
Anti-Magic and fire surged in the air as the fighters grappled and slugged at each other.
Asta may use swords now, but he never forgot. He will never forget those early years he spent protecting Yuno and his other siblings from bullies and unfair adults. He never forgot the countless hours he used on practicing hand-to-hand combat as part of his training.
At some point, kicks were thrown in along with the punch. Both of their stances eventually lost form as the fight continued to devolve into what an outsider would be more likely to describe as something resembling two animals in a territory dispute rather than humans who had challenged each other.
Mereoleona's punches transitioned into wild clawing and Asta's equally wild punches came messy unorganized attempts to grapple.
Eventually, their forms started to flicker out. Asta was unable to maintain unity with Liebe, and Mereoleona, her magic being exhausted by both her own efforts and Asta's.
The two tumbled onto the lip of the volcano and with it came the end of upright combat. Mereoleona instantly went for the leg takedown. Asta countered by wrapping his arms around her waist and hip tossed her to the ground. She didn't let go causing the man to fall on top of her.
She head-butted him and rolled them over, so she was on top, straddling his waist.
Asta wasn't about to let her deal out any punishment. He laced his arms under her armpits and bent them back, forming a lock around her throat causing her to raise up just enough for Asta to roll them back over.
Thinking quickly, he planted himself on her stomach and grabbed her wrist before she could shove him off. He pinned her legs under his.
Despite all of that the former captain was still thrashing around. Behind him her legs were still kicking, her head was shaking, and her chest heaved as she tried to push off the ground. Even under his superior physical strength she still wouldn't submit.
Asta watched her head sway and even years later he wouldn't have an answer for why he did what he did but he leaned over—
And bit her on the neck.
Mereoleona let out a roar, but Asta held on, keeping her head on the ground in one place. His instincts told him it was her most vulnerable spot. He clamped down and hung onto her with all his being.
Then as the seconds passed her rampaging ebbed and her roaring turned into something close to….mewling?
After what seemed like an eternity she completely stopped and went silent except for two words that passed through her lips.
"….. I surrender."
Asta hummed a disbelieving "What?" Through her neck, the vibration went through his lips and onto her skin.
"I said I give up, little runt."
In sheer surprise Asta let go and sat up, leaving a vivid red bite mark on her neck. He didn't dare let go of her wrists for fear it was some kind of set-up.
When he looked down at her she was smiling at him. The strange part was that it wasn't a fierce smile brought upon by pride or confidence. It was soft and demure. An expression he never thought he'd see from her in a million years. Even her ki had reached a level of calm rarely seen among battle junkies.
"….So."
"So what?"
"I've submitted. What do you plan to do with me?" That word made him feel powerful.
She gazed up at him expectantly.
"Let you up of course!" Asta immediately followed up, letting go of her hands and sitting up.
Her body didn't move but her face turned into a frown, and she tilted her head to the side. Asta blinked, feeling her ki flare ever so slightly. Though it wasn't out of malice or bloodlust. It felt more like frustration….and disappointment?
She wasn't the only one either. Liebe let out a long groan inside his head and called him a dense idiot.
Had he said the wrong thing?
Mereoleona's eyes slid back to him and upon seeing his confusion, her eyes lit up and she spoke again.
"….I've come to a realization. You're right, Asta. Let us bask in the hot spring to celebrate your victory!"
"Yeah, I could use a good soak after a fight like that!" Asta said, rolling his shoulders.
—X—
"Are you sure you're okay with this?" Asta said with a blush on his face, trying to look anywhere but in front of him.
Sol's divider still remained in the hot spring after all these years, yet Mereoleona had insisted on bathing together.
She was currently sitting opposite him against the bedrock, doing what Vanessa once described as 'manspreading'. Thankfully the water obscured everything below her neck save for her arms which were above water.
"I don't see the problem." She stated, smirking at his bashfulness. "It's only me and you. Surely a world-renowned hero and a man amongst men like yourself; has seen plenty of women in various stages of undress." She rose in the water just enough to give him a generous view of her cleavage but not enough to actually expose anything important. She was clearly teasing him.
"That's not the point!" He rapidly denied, his face flustered, gazing up at the sky, or any place but her. "You're just…"
"I'm just?"
"You're just too beautiful, and I respect you too much to see you like this!"
Mereoleona laughed. It was a loud laugh that echoed off the rocks and walls of the whole area.
"Did it not occur to you that I might want for you to see me in this state?"
Against his will, his eyes snapped to her. "Wha-?"
His question was interrupted by her standing up and sloshing her way over to him. Asta's eyes flitted back and forth between her firm breasts, her dark nipples, her toned abs, and her wide hips. His eyes finally fell on her amused face as she sat down right beside him, this time she was partially above water, her large chest remained exposed, daring him to look.
He tried to edge away from her, but she caught his wrist, preventing him from going further.
"Do you even know why I called you out here?"
"To see how you measured up against a rival?"
She tilted her head.
"While true, I did desire to test myself against the strongest man I could find," she admitted. "I also made myself a promise as a girl. That the only man I'd acknowledge as worthy of being my mate is not only someone who could win against—but a man among all men who could actually make me submit."
Mereoleona proudly turned her head showing off the bite mark that started to turn into a bruise.
All of a sudden everything finally clicked into place. Fuegoleon and Leo's apprehension, Liebe's unease, her suggestive manner of speaking, and her expression when she finally gave up.
The implications hit him like a sledgehammer. His face started to turn bright red.
Mereoleona once again stood up, stretching one leg over him, she sat down right on his lap. Oddly enough, she didn't touch him at all, her hands remained at her side.
Even through the water, he could feel that despite all the muscle she had, she was still soft in the areas it mattered. Asta struggled to keep his attention on her face rather than wander elsewhere.
"You proved yourself to be exactly the man I was looking for and so much more. You have both the ambition and drive to match my own, not to mention a wild spirit, so I thought I'd finally put you to the test to be my mate."
"I-I don't know what to say…"
Her face lost its confident edge to be replaced by another new expression he had never seen her make before—Uncertainty. She didn't look at him directly and her face was a bit red.
She didn't speak, but honestly, she didn't need to, her body and ki said it all.
Asta knew it, she was rather intense, and it probably scared a lot of people away. Hell, it scared him away when he first met her. He doubted a lot of guys had what it took to keep up with her. She knew it.
She was giving him an out. If he really didn't want this—want her, he could end it now.
He stared up at her and realized they did have a lot in common. They were both wild yet focused on their goals of becoming stronger. They were both fiercely devoted to those they called family and friends. Another more perverted part of him brought up the fact that they both have big chests.
Asta swallowed and came to his decision. He reached out and tenderly grabbed her shapely hips, causing her to look down at him in wonder.
"I want…I want to give this a chance. I want for you to give me a chance."
"Fool. You're a hunter—you take what you want." She said quietly.
He gritted his teeth and nodded, he moved his hand up from her hips to her back and forcibly pulled her towards him. She didn't resist and with a small smacking sound, her body collided into his, her soft supple chest pressed up against his hard scarred one. Her hands wrapped around his back naturally. Her head came to rest under his chin.
"From now on your mine and I won't take no for an answer!"
Mereoleona looked up at him with a soft but coy expression.
"…Oh really? Then claim what's yours."
Asta returned her smile and bent his head down, the next thing he knew, his lips were pressed against hers.
Once again, he was amazed that someone so harsh could feel so soft not to mention warm. Not the blazing wildfire that drove enemies away, but the warm campfire that invited him as close as possible.
She scooted further onto his lap in order to deepen the kiss. A part of him started to stand in attention but neither of them cared; in fact, she actively rubbed against him.
As she ran her hands through his hair, he probed her lips with his tongue, and she let him in without any resistance whatsoever. He basked in how warm her mouth was. His tongue intertwined with hers as she started moaning.
That first moan empowered him, it awakened long-dormant instincts.
He suddenly broke the kiss and grabbed her by the ass. Assisted by the water he hoisted her up a bit and before she could ask why, he roared and bit her on the neck again.
She yowled in pleasure at the pain.
"YES!"
He continued to clamp down on her harder and harder. This time he wanted to leave a mark. It wasn't about winning; it was about showing the world that she was his.
Mereoleona was his territory.
His rival.
His lover.
His mate.
She stopped screaming, leaned down, and bit him in turn, he felt her canines break his skin. It didn't contain the same ferocity he showed her; he could feel it was her way of showing love.
His theory was proven true when her biting transitioned into her kissing his neck. She then put her hands on his chest and pushed off him, a happy, pleased expression on her face.
"There. Now everyone will know not only that I belong to you, but you also belong to me. There's no escaping now. I hope you're ready….Lover Boy."
Asta grabbed her arms and then forcibly switched their positions so that now he was above her and she was in the water. He took no small enjoyment in watching her chest shake and float in the sauna.
He didn't need any more words.
He gave her a reassuring smile….
And kissed her again.
And that was the first chapter both me and Asdf0789 were excited about this one. We both agreed that Mereoleona is our favorite female character so that's why she went first.
I do have ideas in mind for a continuation of Mereoleona, Noelle, Ichika, Mimosa, and Sally. I also have a Vanessa chapter in the works.
But I would love to hear your guy's ideas. For right now I'll stick to F/M because that's what I know and have experienced, but I'll slowly start to push the bounds if the ideas come to me.
Anyways, thanks for reading and please comment if you can, I read everything and try to reply if I'm able too.
