Throne & DxD

Hello Masters-in-Arms, I am here once again to provide you another CH. I do not own any property in this Xover, except for my OCs. Please leave a comment on what think of the story so far and if you have any ideas for future chapters. I am also open do do story commissions if anyone is interested.

Three months had passed since Kio began repaying his debt to Azazel, leader of the Grigori. Living under the alias "Nanashi" to conceal his true identity, he worked tirelessly, taking on jobs that wouldn't even pay enough to buy an In-N-Out order #1.

Though the tasks varied, they all shared one thing in common—they weren't designed for a normal human. Taking on assignments that ranged from reconnaissance to dealing with rogue supernatural entities. Despite his young age and blindness, his efficiency earned him quite the reputation—whispers of a skilled child who could hold his own. Kio approached them with quiet determination, hurrying to pay off the shady man that helped him.

After completing yet another mission, he returned to the small apartment provided by the Grigori. The space was plenty for one person, functional. It suited Kio just fine. The solitude offered him a reprieve from the annoyance of his work, a place to unwind and gather his thoughts.

But today was different. As he approached the building, a presence made itself known. A pulse of energy crackled in the air, faint but unmistakable. He'd felt it before—the aura of a dragon. And not just any dragon. This was Valencia (Vali) Lucifer, the White Dragon Emperor.

"You're Nanashi, right?" her voice called out, clear and commanding as she stepped out from the shadows. Her silver hair shimmered under the dim light, and her confident smirk radiated pure determination. "I heard you're strong for a child. Even more impressive for a defective human."

Kio didn't stop walking. "Lucifer Valencia, What do you want?" he asked flatly, his tone devoid of interest.

"Oh! you have heard of me? You can call me Vali, and what I want is a fight," she said, cutting to the chase. "I want to see what you've got."

He paused briefly, tilting his head in her direction. "Yes, the old man mentioned you a lot, and what you are asking for is pointless," he replied, his voice calm but firm. "I have no reason to waste energy on someone else's interest."

Vali's smirk widened. "Oh come on, don't be like that. This is just a friendly bout. I can be very persuasive; I'll make sure you change your mind."

Kio sighed, continuing inside, brushing off her presence as though she were nothing more than an annoyance. Walking into his room and slamming the door behind him, echoing though the night.

"I think you were a little too straight forward and forceful, Vali." a low and regal voice calls out to her. "It will be fine, Albion. I think that this is the beginning of a beautiful rivalry." she responds.

She leaves, heading in her own direction.

Vali, however, was not one to take no for an answer.

The next few days became a trial of patience. She showed up at his apartment unannounced, determined to pester him into agreeing. She barged into his room while he was asleep, her voice cutting through his dreams like a blade.

"Get up, Nanashi! Let's go!" she yells, not as soon as she was forced out by a palm strike.

"Leave," he muttered, pulling the blanket over his head.

Even his meals weren't safe. Sitting at his small table, finally enjoying a moment of peace with an egg on top of a bowl of rice, miso soup, and tuna. He heard the telltale sound of the window sliding open. Vali hopped through, landing gracefully in the middle of the room.

"FIGHT ME!" she demanded, ignoring his exasperated, yet deadpan expression.

"If I agree, will you leave me alone?" he asked, his tone heavy with resignation.

"Sure," she said, her smirk victorious.

He sighed, setting his chopsticks down. "Fine. One fight. Then you leave me in peace."

Vali's grin widened. "Deal."

Vali smirked triumphantly as she grabbed Kio by the arm and effortlessly hoisted him into her arms. Before he could even protest, her dragon wings unfurled with a powerful snap, and they were airborne. The rush of wind whipped past them as Kio sighed, resigning himself to whatever madness she had planned.

"Where are we going?" Kio muttered, the fatigue of her relentless badgering weighing on his tone.

"An appropriate venue with an audience galore," Vali replied, her voice brimming with excitement. "You're going to show me just how strong you are, Nanashi."

In minutes, they arrived at a sprawling training ground outside the Grigori headquarters. Fallen angels sparred in groups, their weapons clashing and magic lighting up the air. Vali descended, landing with a dramatic flair in the center of the chaos. She dropped Kio unceremoniously, and with a commanding glare, shouted, "Clear out! This space is mine now!"

The sparring ceased as the fallen angels hesitated, murmuring among themselves. One glare from Vali was enough to send them scattering, giving the duo plenty of room to fight.

Kio dusted himself off, his expression unamused. "You really know how to make an entrance."

Vali grinned, her eyes gleaming with excitement. "It's part of the fun. Now, get ready. Show me what you've got."

Kio sighed again, loosening his shoulders and rolling his neck. "You're really not going to let this go, are you?"

"Nope," she replied, her stance shifting as she prepared to attack.

She wasted no time, launching herself at him in high speed. Her movements were sharp and precise, a flurry of punches and kicks that forced Kio to stay on the defensive. He ducked under a kick, his body reacting instinctively as he countered with an upper cut aimed at her chin.

Vali blocked it with ease, grinning. "Not bad. But you'll have to do better than that!"

She pressed the attack, her strikes coming faster and harder. Kio met her head-on, parrying her blows with precision. His movements were fluid, his breathing steady despite the intensity of the fight.

The two fighters moved in perfect rhythm, their clash could be heard outside the training ground. Vali's style was aggressive and relentless, each strike aimed to overwhelm. Kio, on the other hand, relied on his sharp reflexes and economy of motion, using her momentum against her whenever he could.

Vali feinted left before spinning into a low kick, sweeping at Kio's legs. He jumped back, narrowly avoiding the strike, and retaliated with a spinning backhand that forced her to dodge. She backed off, receiving a scratch on her cheek, blood seeping out.

"You're better than I thought," Vali admitted, circling him with a predatory grin.

"And this fight is just a waste as I thought," Kio shot back, sidestepping another one of her punches.

Vali laughed, exhilaration radiating from her with every strike. "You know, you have to enjoy the little things in life. That which is exciting!"

"I don't have that kind of luxury. All I need is to survive so that I can know what kind of tomorrow is there" Kio replied flatly, catching her wrist mid-punch and twisting it to throw her off balance.

She rolled with the motion, flipping back onto her feet and coming at him again without missing a beat. Their movements became faster, more intense, each of them pushing the other to their limits. Sweat dripped down Kio's face, heavy breathing, but he didn't falter.

As Vali and Kio charged at one another, their fists collided with explosive force, neither holding back nor bothering with defense. The sheer impact shook the air around them, their determination and raw strength clashing head-on.

In that instant, something strange happened, an understanding of one another. They both recoiled, their fists dropping as they are baffled.

"Well… that new!" Kio muttered, his voice tinged with shock.

Vali's breath hitched, her usual composure faltering. "The hell was that? You know what, forget it. Round 2!"

Neither could answer, but the connection lingered.

Vali delivered a flying kick that Kio narrowly blocked with both arms, the force of the impact, cracking his bones and driving him back a few feet. He readies himself, countering with a rapid series of strikes that forced her onto the defensive.

As the clash between Vali and Kio intensified, high atop one of the arena walls, a figure stood silently, his arms crossed and his gaze fixed on the fight below. Baraqiel, clad in his dark coat, watched the battle unfold with a sharp, unreadable expression. His wings remained tucked behind him, but the faint glow of the arena lights reflected off his form, adding an air of quiet authority.

The sound of rustling interrupted his focus, and he glanced over his shoulder to see Azazel approaching, a bucket of popcorn in hand and a mischievous grin on his face.

"Quite the show, huh?" Azazel said, plopping down on the edge of the wall beside Baraqiel and tossing a piece of popcorn into his mouth. "Vali's really going all out. She must really like this kid to put in so much effort."

Baraqiel grunted, his gaze returning to the fight. "Or she's just bored. You know how she gets."

Azazel chuckled. "True, true. But still, there's something... intriguing about him."

"Nanashi?" Baraqiel asked, his tone skeptical.

"Yeah," Azazel replied, leaning back casually. "A blind human kid holding his own against Vali is no small feat. And have you noticed how calm he is? No panic, no hesitation—he's not just surviving. He's analyzing, adapting. That's not normal."

Baraqiel nodded slightly, conceding the point. "I've noticed. He's not like the other humans we've dealt with. His strength and skill are... familiar. Like that of an old friend." A small grin cracked on the corners of his lips

Azazel grinned, tossing another piece of popcorn into his mouth. "That's what makes it fun, isn't it? He just shows up out of nowhere one day, becoming our part-timer, and somehow ends up getting her attention. I'm glad she found a new friend."

Baraqiel's expression darkened slightly. "There's more to it than that. I've been watching him. He's disciplined, but there's a weight to him—a burden. He hides it well, but it's there."

Azazel raised an eyebrow, intrigued. "You think he's running from something?"

"No," Baraqiel said. "He's running toward something."

Azazel hummed thoughtfully, his gaze shifting back to the fight. Below, Vali delivered a series of rapid punches, her movements precise and relentless. Kio countered with equal precision, his calm demeanor unshaken despite the intensity of her attacks.

"Whatever it is," Azazel said, "he's got potential. And if Vali keeps dragging him into fights, we might get to see just how far that potential goes."

Baraqiel remained silent, his sharp eyes never leaving the combatants. Azazel, as relaxed as ever, continued munching on his popcorn, clearly enjoying the show.

As Vali and Kio's battle reached new heights, the two observers remained perched above, their conversation fading into a quiet curiosity about the enigmatic boy below.

For a moment, they broke apart, Kio continues to breathing heavily, as Vali barely broke a sweat, but neither willing to back down.

"You're holding back," Vali accused, her eyes narrowing.

"So are you," Kio replied, his stance steady.

Vali grinned. "You're not wrong there. Let's fix that."

The tide of the battle shifted suddenly as Vali's energy surged, radiating power that made the air around them hum. Her aura became almost suffocating, and Kio instinctively took a step back, his calm exterior cracking as he sensed the difference in strength.

"Vanishing Dragon: Balance Breaker!" a deep, resonant voice called out, echoing through the arena.

A blinding light enveloped Vali, forcing the onlookers to shield their eyes. When the light subsided, she stood fully armored in the gleaming white dragon armor of the Vanishing Dragon Emperor. Her form radiated an overwhelming presence, the intricate design of the armor and glowing highlights exuding raw power.

"Vali," Albion within her spoke. "Are you sure about this? This child—this human—isn't on your level. Going all out could kill him."

Vali smirked beneath her helmet, her tone confident and almost playful. "Relax, Albion. Look closely. See that wicked smirk on his face?"

Albion fell silent for a moment, observing. Sure enough, despite the nervousness in Kio's stance, a faint grin tugged at the corners of his mouth.

"Interesting," Albion murmured.

Vali raised a gauntleted hand, pointing at Kio. "Show me what you're really capable of!"

Kio's heart raced as the pressure of Vali's power pressed down on him. He took another step back, sweat forming on his brow. He knew there was no escaping this fight, but the sheer difference in power was staggering.

As he steadied himself, his foot brushed against something on the ground. He noticed something hard in the dirt. With a swift motion, he kicked it up, catching it midair. The weight in his hand was reassuring, though far from ideal.

It was a broken sword, the blade jagged and incomplete. He ran his fingers along its surface, noting the worn hilt and fractured edge.

"Not exactly perfect, but it will have to do," he muttered to himself, gripping the hilt tightly.

Left with no other option, Kio placed his other hand on the blade, gripping it as though pulling it from a scabbard. Cutting himself, blood trickled from his palm, running along the broken blade.

The moment the blood touched the metal, it began to shift. The crimson liquid hardened, crystallizing along the fractured edge. With each heartbeat, the blade grew, forming a crooked yet deadly edge that gleamed with an unnatural light.

The onlookers gasped as the weapon completed itself, jagged and raw but exuding a fierce aura. Baraqiel's eyes narrowed from his perch, and even Azazel paused mid-bite, his popcorn momentarily forgotten.

Kio took a deep breath, steadying himself. The weapon felt alive in his hands, as though it had been waiting for this exact moment. His earlier nervousness gave way to focus, his mind sharpening like the edge of the blade.

"Interesting," Vali said, her tone tinged with excitement. "You really are full of surprises."

Kio adjusted his grip, his knuckles whitening as he raised the newly-formed weapon. "You wanted me to stop holding back," he said, his voice calm despite the storm raging within. "Fine. Let's finish this."

Kio and Vali charged at each other with everything they had. Vali's fists blazed with energy as glowing magic circles formed in front of her gauntlets, each crackling with destructive power. Kio's newly-formed aura sword flared a brilliant crimson, its jagged edges pulsing with raw intensity.

The two combatants closed the distance in an instant, their attacks primed to collide in a clash that would shake the entire arena.

But before they could make contact, a figure descended like a thunderbolt between them.

WHAM!

With one devastating swing of his arm, Baraqiel sent Vali and Kio flying in opposite directions. Both fighters hit the ground hard, as unconsciousness claimed them.

The gathered crowd erupted in boos, their disappointment echoing across the arena. Some shouted in frustration, while others groaned about the abrupt end to the fight. Even Azazel, still perched on the wall, tossed his empty popcorn bucket aside in mock outrage.

"Baraqiel, you killjoy!" Azazel called out, shaking his head. "They were just getting to the good part!"

Baraqiel ignored the crowd and glanced down at the unconscious fighters, his face calm but resolute. "This fight was getting out of hand," he said, his tone leaving no room for argument. "Neither of them knows when to stop. They'll thank me later." Hitting the audience with an intense stare for good measure.

Azazel rolled his eyes, muttering something about ruined entertainment as he stood up and walked away.

…

A few days later, Kio sat in his room, his body still sore and bandaged from the fight. The lingering ache of his injuries was a constant reminder of how close he had come to losing control during that battle. He stirred the butter pasta noodles in the pan, the rich aroma of garlic and basil pesto filling the air. Cooking was one of the few things that kept him grounded—a brief moment of peace amidst the chaos.

A knock on the door pulled him from his thoughts.

"Nanashi," Vali called from the other side. "Open up."

Sighing, Kio turned off the stove and made his way to the door, letting the walls guild him. When he opened it, Vali stood there, her usual confidence tempered by a faint curiosity.

"Come in," Kio said, stepping aside.

Vali entered, glancing around the room with a subtle air of detachment. The smell of food caught her attention, and her stomach gave a soft growl. She raised an eyebrow but said nothing, her gaze settling on him.

Kio returned to the kitchen, finishing up the meal and plating two portions of the butter pasta. Setting the plates on the small table, he gestured for her to sit.

"You're surprisingly domestic," Vali said as she twirled some noodles on her fork.

"Cooking isn't about being domestic," Kio replied evenly. "It's about knowing basic life skills. And I'd rather eat something good than whatever the cafeteria calls food."

Vali smirked, taking a bite. "Fair point." Her face light up with bliss after the first bite.

The two ate in silence for a while, the quiet punctuated only by the clink of forks on plates. Finally, Vali broke the silence.

"During the fight," she said, her tone contemplative, "Something strange happened. Whenever we clash ... I felt something, it was strange yet comforting."

Kio puzzled, his brow furrowing slightly. "What?"

Vali set her fork down, her fingers lacing together as she leaned forward. "It seems to me we are not so different from each other."

"I feel that you have gone through so much just to get where you are at right now," Vali admitted, her voice steady but tinged with curiosity. "Painful moments. Constant battles. There was so much blood lust, so much suffering..." She trailed off, her gaze locked on him. "It was like I was being pulled into your world."

Kio's expression darkened, his jaw tightening. For a moment, he didn't respond, and Vali wondered if she'd crossed a line. But then, with a heavy sigh, he spoke.

"You're not imagining it," he said quietly. "I felt the same thing too."

Vali's eyes widened. "Hahaha~ that unbelievable. I read that people who experience similar events can understand one another. I did not believe in that shit until today."

Kio nodded, his voice calm. "Yours felt stronger. It was cold and lonely. But you manage to survive and became stronger."

Vali leaned back in her chair, the weight of his words sinking in. "So it wasn't just me," she murmured. "Our pasts were... fucked up one way or another."

Kio's mind replayed her words. "It must've been triggered by the fight," he said after a moment. "The intensity, the energy we put into it... maybe it forced some kind of connection."

"If that's true, then maybe we're more alike than I thought." Vali responds, while looking though Kio's room. For a moment, the two sat in silence again, the weight of their shared revelations hanging heavy in the air. But this time, the silence felt different—less awkward, more understanding.

"Suffering," she said finally, her voice quiet but firm. "What we share in common, it leaves scars. It burns into you, twists you. But it also makes you stronger. Power and suffering—they're two sides of the same coin. The more you endure, the more you can wield."

Kio's expression became unreadable. "So you think power is just a reward for pain?"

"Not a reward," Vali replied, shaking her head. "More like... a consequence. Suffering pushes you to adapt, to grow. It forces you to find strength you didn't know you had. I wouldn't be who I am without it, and I don't think you would, either."

Kio considered her words, his mind turning over his own experiences. "Maybe you're right," he said quietly. "But that doesn't mean it's worth it."

Vali leaned forward, her gaze sharp. "It's not about worth, Nanashi. It's about survival. And the stronger we are, the less likely we are to suffer again."

"Well, thanks for the food. I'll see you around, Nanashi." Vali said as she opens a window and jumped out. Kio collect the dishes and cleans up after himself, thinking that what Vail said about suffering, may have some merits.

Back in his office, Azazel leaned back in his chair, a faint smirk tugging at his lips as he reviewed the reports on his desk. The papers, stamped with the Grigori medical department's insignia, detailed observations about a certain person. The findings were as intriguing as they were baffling.

"Just as I thought," Azazel murmured, his golden eyes scanning the text. He placed the papers down and turned his gaze to the large window behind his desk. The sprawling Grigori compound stretched out below, its lights flickering faintly against the darkening sky. His smirk softened, replaced by a rare moment of solemnity.

"I hope you're doing well, old friend," Azazel said quietly, his voice barely above a whisper. "It seems the world's still full of surprises. I wonder what you'd make of all this. Could it have been be FATE?"

…

On the other side of the world, far from the Grigori headquarters, an armored vehicle rumbled through the desolate terrain. Inside, the dimly lit interior hummed with the sounds of machinery and the tapping of a keyboard.

A young girl with a mechanical arm sat at the console, her small figure dwarfed by the imposing monitors and equipment surrounding her. Her mechanical fingers danced across the keys, data streams and coordinates reflected in her glowing blue eyes. She squinted at the screen as a signal pinged, a small icon blinking steadily.

A satisfied grin spread across her face. "Finally," she whispered, her voice carrying a mix of excitement and determination. "I've found him."

She leaned back in her seat, staring at the location displayed on the monitor. The vehicle's engine roared to life, the vibrations reverberating through the cabin as it began to move.

"Let's go," she muttered to herself, her mechanical hand tightening into a fist. "It's time to meet him."

The vehicle sped off into the distance, its destination locked and the girl's resolve burning brightly.
