I was born as an orphan in Kuoh Town.
No parents. No family. Just a name— Riku —and a file that said I was abandoned as a baby near the outskirts of town.
Life wasn't bad, per se. I had a roof over my head, a high school uniform on my back, and more importantly, all the memories of my previous life. I remembered anime. Manga. Novels. Even the crazy physics behind Tensura's magicules and Fairy Tail's Lost Magic.
That knowledge gave me a bit of a leg up, but it also made me… lonely. It's hard pretending to be a normal teenager when you remember one lifetime' worth of cringe and context.
The weird part? I always felt different. Stronger. Not freakishly so, but enough that it made me cautious. Especially when I realize the kind of world I am in, the fact that I am in Kuho Town gave it away.
It is clear that I am in the world of highschool dxd, a world filled with Devils, fallen angels, angels, dragons, sacred gears, yokai, gods and other supernatural creatures with a helping of fan service mixed it.
It has been 16 years since i was reincarnated into this world, I am a first year in high school in the same class as Issei and he already has a reputaion for being a pervert with his two friends.
I was walking through the narrow alley behind the convenience store where I worked part-time, my mind still buzzing with plans for the future. I know the greatest possible threats in this world from canon, Ophis, the Khao Brigade, Kokabiel, Rizievim Livan Luficer.
The scholarship to Kuoh Academy was suspicious—I never applied for it, which meant either Rias or Sona was keeping tabs on me. Maybe both.
The thought should have made me more cautious, but I was too caught up in possibilities. Join a peerage, grow stronger, maybe even figure out my heritage. Eventually get my own Evil Pieces and create the family I never had.
I was so lost in thought that I almost missed the sound of footsteps echoing mine.
Almost.
The hairs on the back of my neck stood up—some primal instinct screaming danger. I stopped walking and listened. The footsteps stopped too.
"Shit," I muttered under my breath, picking up my pace.
The footsteps matched my speed.
I broke into a run, but it was too late. A figure dropped from the fire escape above, landing directly in my path with inhuman grace. The streetlight caught his face—wild white hair, manic grin, and eyes that held nothing but gleeful bloodlust.
Freed Sellzen. Even without his priest robes, I recognized that psychotic smile from the anime.
"Well, well, well," he purred, drawing a gleaming sword from beneath his coat. Holy energy radiated from the blade like heat from a furnace. "What do we have here? A little half-breed trying to play human."
My blood turned to ice. Half-breed. He knew what I was.
"I don't know what you're talking about," I said, backing away slowly. My hands were shaking—when did they start shaking?
"Oh, don't play dumb with me, boy." Freed's grin widened impossibly. "I can smell the devil stench on you from a mile away. Mixed with something else... something that makes my skin crawl with anticipation."
He took a step forward, and I felt it then—a stirring deep inside me, like something ancient waking up. Power I'd never accessed before, responding to the threat.
"The funny thing is," Freed continued, twirling his sword casually, "you don't even know what you are, do you? I can see it in your eyes. Poor little orphan, all alone in the world, not knowing mommy and daddy were monsters. But don't worry," Freed raised his blade, holy light blazing from its edge, "Uncle Freed is here to put you out of your misery!"
He moved faster than anything human should be able to. One moment he was five feet away, the next his sword was inches from my chest. I tried to dodge, but I was too slow—too human.
The blade pierced through my uniform, through skin and bone, holy energy burning through me like liquid fire. I screamed as the power inside me recoiled violently from the sanctified steel.
"There it is!" Freed laughed, twisting the blade. "I can feel your devil blood burning! But what's this other power? So familiar, yet..."
The stirring inside me became a roar. Something was awakening—multiple somethings. Ancient bloodlines that had lain dormant for sixteen years suddenly surging to life in response to mortal danger.
My vision sharpened impossibly. I could see the holy energy around Freed's blade, could feel the exact composition of power flowing through it. More than that, I could sense something else—water in the air, in the pipes running through the building walls, responding to my desperation.
"Dragon..." I gasped, not understanding where the word came from. "Sea serpent..."
Freed's eyes widened. "No fucking way. You're not just any half-breed. You're—"
He never got to finish. My awakening power lashed out instinctively—water erupting from the storm drains, ice forming in the air around us. For a brief moment, I felt magnificent, powerful, like I could tear this madman apart.
Then the holy energy reached my heart.
Pain exploded through every nerve. The awakening power flickered and died as the sanctified blade carved through my chest. I collapsed, blood pooling beneath me, my vision already starting to fade.
"Well, that was disappointing," Freed sighed, pulling his sword free. "I was hoping for more of a fight. Oh well, at least I know what to tell the boss. Mixed blood of two Great Houses... he'll be very interested."
He walked away, whistling cheerfully, leaving me to die alone in a dirty alley.
'This is it,' I thought, staring up at the narrow strip of sky between the buildings. 'After all that planning, all those dreams of having a peerage, a family... I die like this.'
Confirmed.
Extra skill: [Sage] Acquisition Successful.
Wait... what? That voice... it's like something out of Tensura. But that's impossible, unless—
"Urgh" my thoughts were interrupted by the heat and pain left behind by the low grade holy light sword that stabbed me.
That's when I heard it again—a voice that seemed to come from everywhere and nowhere at once.
Confirmed.
[Heat Resistance] Acquisition Successful.
[Pain Resistance] Acquisition Successful.
[Holy Attack Resistance] Acquisition Successful.
The voice is real. This is actually happening. Am I... am I dying and being reborn like Satoru Mikami/Rimuru was?
Am I going to die again? Wasn't I a reincarnation once already? I can't catch a break can I?
God, this is such a pathetic way to die.
The cold was seeping in now, making my thoughts sluggish. My strength was fading fast.
'I never even got to find out who my parents were. Never got to understand what I really am. All that knowledge from my previous life, all those plans... wasted. I wanted to use Demonic power to recreate [archive magic] from Fairy Tail.'
Request Accepted.

The cold was getting worse, but somehow the voice was becoming clearer.
Confirmed.

The pain was fading now, replaced by a strange floating sensation. I was dying, but somehow I felt... peaceful. Protected.
The world was getting darker, but I could still hear the voice, still feel skills settling into my soul like stars being born.
The last thing I felt before consciousness faded entirely was a sense of profound possibility. I'd died as a powerless half-devil who never understood his heritage.
I was about to be reborn as something far more interesting.

Daemon Realm
Darkness.
Then... awareness.
I exist. That's the first coherent thought I manage. Not "I'm alive"—because whatever I am now doesn't feel alive in the traditional sense.
[Archive] activated automatically, cataloging sensations as they return:
- No heartbeat detected
- No breathing required
- Ambient magicule concentration: Extremely High
- Current location: Unknown forest environment
- Body composition: Spiritual Life Form confirmed
I try to move and find myself... floating? My form feels insubstantial, like I'm made of shadow and will rather than flesh and bone. When I look down at where my hands should be, I see translucent, claw-tipped appendages wreathed in dark energy.
Suddenly, my fading consciousness sharpened. Information flooded my mind—not just my memories, but a perfect catalog of everything I'd ever learned, organized and searchable. I could feel the skill settling into my soul like a missing piece finally clicking into place.
I could feel [Sage] connecting with [Archive], the two skills synergizing in ways that felt natural, right. Information wasn't just being stored anymore—it was being analyzed, cross-referenced, turned into actionable knowledge.
Lesser Daemon. The Voice of the World called me a Lesser Daemon.
The memories flood back—Freed's blade, the burning pain, and then... skills. So many skills acquired in those final moments. Including ones I never knew I had.
[Dragon Tamer], [Dragonification], [Sea Serpent of the End]...
My devil heritage. It had been there all along, dormant until death awakened it.
Buné family... Leviathan family...
I wasn't just any half-devil. I was the mixed-blood descendant of two of the most powerful devil lineages in existence, and I never knew.
No wonder Freed could sense what I was. No wonder I always felt different.
And now, in a world where such knowledge might actually matter, I finally understand what I truly am.
The question is: what do I do with this power?
-----------------------------------------------------------------
Kuho town
6 minutes after mcs death
"His residual energy signature ends here," Akeno said softly, her usual playful demeanor replaced by uncharacteristic tension. Purple lightning flickered around her fingertips as she knelt beside the alley entrance. "But there's something else... something that feels wrong."
Rias nodded grimly, her crimson hair catching the streetlight as she surveyed the narrow space between buildings. "I can sense it too. Holy energy... and blood."
Behind them, Sona adjusted her glasses with barely concealed worry. "We should have approached him sooner. The energy readings we've been monitoring for months... if we'd just made contact instead of observing—"
"Second-guessing won't help now, Kaichou," Tsubaki interrupted gently, though her own voice carried an edge of regret. "We need to focus on finding him."
The four devil heiresses moved deeper into the alley, their supernatural senses painting a picture none of them wanted to see. The scent of spilled blood grew stronger with each step, mixed with the acrid burn of sanctified weapons and something else—something that made their devil instincts recoil.
"There," Rias whispered, stopping abruptly.
In the shadows between two dumpsters, illuminated by the harsh glow of a flickering streetlight, lay a figure in a Kuoh Academy uniform. The white shirt was stained dark with blood, and the body lay unnaturally still.
"Riku..." Sona breathed, recognizing the quiet student they'd both been monitoring.
Akeno was the first to reach him, her usual sadistic smile nowhere to be found. She knelt beside the body, her hands hovering over the massive wound in his chest. "He's... he's gone. The holy energy burned right through him."
"But that's not all," Tsubaki said, her voice tight with confusion. She was examining the area around the body, her analytical mind cataloging the evidence. "Look at this—water damage on the walls, ice crystals that haven't melted despite the temperature. There was a fight here."
Rias knelt on Riku's other side, her blue-green eyes scanning his pale face. Even in death, there was something about him that had always intrigued her—a presence that felt familiar yet foreign, powerful yet restrained.
"The scholarship," she murmured. "We gave him that scholarship because we sensed something. Demonic energy, but... different. Older."
"Mixed blood," Sona concluded, her strategic mind piecing together the clues. "We suspected as much, but we couldn't identify the lineage. His energy signature was too complex, too layered."
Akeno placed her hand near the wound, flinching as residual holy energy stung her fingers. "Whoever did this knew exactly what they were hunting. This wasn't random—this was an execution."
"Wait," Tsubaki said suddenly, moving closer to examine something that had caught her eye. "Rias-sama, Sona-sama... look at this."
She pointed to the ground around Riku's body. Carved into the concrete were strange patterns—not quite magic circles, but something that spoke of power being unleashed.
"Dragon," Rias whispered, recognizing some of the symbols. "And... is that a serpent motif?"
Sona's eyes widened behind her glasses. "That's not possible. Those are clan markers. Specifically..." She trailed off, her analytical mind working through the implications.
"Buné clan dragonification sigils," Akeno finished, her voice filled with shock. "And Leviathan family sea serpent manifestations. But that would mean..."
"He was mixed blood of two Great Houses," Rias completed, staring down at the boy they'd been too cautious to approach. "Not just any devil heritage—he was nobility. Potentially more powerful than any of us realized."
The four devils stood in stunned silence, the weight of their discovery settling over them like a shroud.
"We failed him," Sona said quietly, her usual composed demeanor cracking. "We knew he was different. We sensed the potential. But instead of reaching out, we watched from a distance."
"We were being careful," Rias replied, but her voice lacked conviction. "Strange energy signatures can mean danger as often as opportunity. We needed to understand what we were dealing with first."
"And now he's dead because we took too long," Akeno added, uncharacteristic sadness in her tone. "Someone else recognized what he was and decided he was too dangerous to live."
Tsubaki knelt down, examining the body more closely. "There's something else. His expression... he doesn't look surprised. Terrified, yes, but not surprised. As if he knew this might happen."
"He knew," Rias realized. "Somehow, he knew about our world. About what he was. Maybe not the specifics, but..." She gestured at the evidence around them. "This awakening didn't happen by accident. It was triggered by mortal danger."
"A final desperate attempt to save himself," Sona concluded. "His bloodline activated in his last moments, but it was too late."
"We need to find who did this," Rias said, her voice hardening with determination and barely controlled anger. "No one murders someone under our protection in our territory and walks away."
"Agreed," Sona replied, her strategic mind already working through possibilities. "The weapon signature suggests a church militant. Probably a rogue priest or exorcist."
Akeno's expression had shifted to something dangerous. "The holy energy residue is still fresh. Whoever did this is confident enough to use sanctified weapons in devil territory. They're either very stupid or very well protected."
"Or both," Tsubaki added grimly. "We should inform our families immediately. If someone is hunting mixed-blood devils, especially those with Great House lineage..."
"We could all be targets," Rias finished.
Sona stood up, brushing dust from her school uniform. "We can't leave him here. He deserves better than to be found by human authorities and written off as another random murder."
"What do you suggest?" Rias asked. "His heritage makes this complicated. We don't know which family might claim him, if any are even still alive."
"We treat him as what he was," Akeno said softly. "A student under our protection who died because we failed to act. The least we can do is give him a proper devil's funeral."
Tsubaki nodded. "I'll contact the necessary authorities in the underworld. Mixed blood or not, Great House lineage demands certain protocols."
As they prepared to move the body, Sona paused, looking down at Riku's peaceful face one last time. "I wonder what he could have become. With that kind of heritage, properly trained and supported..."
"He could have been extraordinary," Rias agreed quietly. "A bridge between the old nobility and the new generation. Someone who understood both power and restraint."
"Now we'll never know," Akeno said, her voice carrying a weight of regret that would linger long after this night.
As they carefully lifted Riku's body using their devil magic, Rias made a silent promise. Whoever had done this would pay. Not just for the murder, but for robbing the devil world of someone who might have made a real difference.
"We should have been better," she said aloud as they prepared to transport him. "All of us. We sensed his potential and chose caution over compassion."
"Then we learn from this," Sona replied firmly. "The next time we encounter someone like him—someone caught between worlds—we act. We reach out instead of watching from the shadows."
"The next time," Tsubaki agreed. "If there is a next time."
But as they disappeared into the night carrying their fallen schoolmate, none of them could know that in a world far from theirs, the soul they mourned was already beginning a new chapter—one where his dreams of family and belonging might finally find fulfillment.
The alley fell silent once more, but the impact of that night's discovery would ripple through the underworld for years to come. A mixed-blood heir of two Great Houses, murdered before his potential could be realized—it was exactly the kind of tragedy that started wars.
And in the deepest vaults of devil nobility, ancient family records would soon be searched for any mention of a child who went missing sixteen years ago, when a devil and their human lover tried to give their son a normal life.
Some secrets, they would learn, were worth dying for.
Others were worth killing for.
