Reborn as the Doomed Succubus
Regina suddenly opened her eyes, and I found myself lying in an unfamiliar space. The ceiling above, and as I looked around, it was a scene straight out of a medieval fantasy—a stately room filled with antique furnishings. From the ceiling etched with intricate patterns to the curtains adorned with swaying decorations fluttering in the breeze from the half-open window. Even the bed I was lying on. It was packed with things I'd never seen before. Had I ever bought stuff like this? No, my room hadn't even been this big to begin with. ...And I'd never seen a ceiling that high before either.
This isn't my room. It didn't take long to realize that. Or rather, maybe it took too long. No matter where I looked, it was nothing like my room, so it was ridiculous that I hadn't noticed right away. Was I just that sleepy? My head felt sluggish, like it wasn't working properly. But now that I was somewhat alert, it was time to calmly assess the situation.
In the fantasy novels I usually read, protagonists immediately jumped to reincarnation. Unfortunately, that wasn't my style. But that was too unrealistic anyway. Reality is reality, fiction is fiction. So, hypothesis one—being transported or reincarnated into another world—was scrapped. The most likely scenario? I'd been kidnapped by a gothic-medieval-fantasy-otaku-yandere girl obsessed with menhera tropes.
Does that even make sense? ...There were two main reasons for that thought. First, this room was unmistakably far from anything modern. Second, my body wasn't responding. And honestly, being kidnapped by a creepy fat bearded uncle sounded worse for my mental health than a clingy yandere girl.
Am I tied up? No, it wasn't that. It was more like my body was completely limp, devoid of strength. Even turning my head was a struggle; I could only roll my eyes. Had the kidnapper drugged me with something weird?
That's when it happened. With a soft click, the door opened, and the presumed kidnapper entered the room.
Oh... Seeing her confirmed that my hypothesis was at least half right. I couldn't say if she had the yandere menhera vibe, but she was undeniably a stunning beauty. Golden hair so radiant it seemed like it would glow sunset hues in a valley. Crimson eyes like embedded rubies. Skin so pale and creamy it looked like it'd never seen sunlight. Her movements were elegant yet seductive, even endearing.
An incredible beauty...! Why would someone so refined kidnap a lowly guy like me? I gaped blankly at my kidnapper. She was more beautiful than anyone I'd ever seen—not just my high school crush, Minji Kim, or any celebrities from the internet.
By then, I'd already accepted being kidnapped. If it was by someone this pretty, it might even be a good thing. I had no strong attachment to my old life anyway, and maybe my brain was pickled from reading too many of these genres. But there was one problem: her outfit was way too revealing. For a guy like me who'd never seen a woman's bare skin up close, it was overwhelmingly provocative.
Is she wearing clothes, or is she naked? Strangely, though, staring at her curvaceous figure didn't stir any lust or dirty thoughts. Maybe because her beauty was too otherworldly.
Then, the gracious kidnapper's gaze met mine. Our eyes locked, and her eyes curved into a gentle smile.
"Our baby’s already awake?"
Baby? Was she into that kind of play? Sorry, but I don’t know much about that stuff.... Flustered by the sudden pet name, I stammered incoherently as she leaned in close. A sweet, sugary scent wafted faintly from her skin.
...Uh...
"Why aren't you sleeping more? Hungry for milk?"
Milk. Yeah, my stomach does feel empty.
"Ughhh...."
Eh? Why does my voice sound like that? Is my tongue numb?
She smiled brightly and strode over, leaning in. Her exposed cleavage filled my vision completely. Whoa, why are you doing this? Not that I hate it.
...This vixen! She's totally trying to seduce me!
More importantly, fix my tongue! I tried to calm her down first, but whether it was paralyzed or cut off, words wouldn't come out properly.
"Abubu...."
"Aww, is that so, our baby?"
Now I noticed—she even had horns. Kidnapping me to a gothic-medieval-fantasy room wasn't enough; she paralyzed my body, cut my tongue, cosplayed herself, and now wanted baby play with her victim?
Dangerous. Crisis dawned on me too late. Was I about to lose my precious virginity like this...? To this exotic, ultra-beauty cosplayer who locked me up and called me baby?
Eh? Actually, maybe she's a nice person? ...Snapping back to reality wasn't easy. Her faint, alluring scent seemed to scramble my thoughts, disrupting my mind.
I tried to stay rational, but it didn't last. She slipped her hands under my armpits and effortlessly lifted me up.
Huh? My body floated into the air so easily. I wasn't heavy to begin with, but for her slender frame to lift me like this was bizarre. As I tilted my head in confusion, puzzled by the situation, my body came into view.
Huh??? So... not the slightly skinny adult male body.
"Shall our baby have some milk?"
...But a cute little baby's body. Panicking, I tried to move, and in response, my tiny, twig-like limbs wriggled slightly. Had I really reincarnated like in those novels? Or was I hallucinating from insanity? But seeing her smiling purely while holding me, it couldn't be a hallucination or dream. The thick, mind-clouding scent, the soft, fluffy sensation against her... Her tender whispers. Every sense screamed that this was reality.
Wait, then this woman calling me baby is...
Mom...?
* * *
In conclusion, that woman was indeed the mother of this new body—mine.
She seems busy, so I don't see her face often... Still, time flew by incredibly fast. As a baby, I spent most of it asleep, and whenever I woke from dreams, I was surrounded by beautiful women, so just watching them made time zip by. They say really pretty or handsome people are entertaining to just look at. It was true. And whenever I fussed from boredom while awake, horned maid sisters would rush over from everywhere, scoop me up, pat my back, and whisper lullabies so sweetly... Ugh. I almost resented this overly sleepy baby body. Those back pats put me to sleep instantly; I barely got to enjoy it. Well, thanks to that, time passed quickly.
"Hm."
Staring at the full-length mirror in front of me, I saw a doll-like baby striking a majestic pose, glaring at the reflection. This girl's name was Regina Diabolos. Yeah, what can I say? It was this body's name.

...Cool. Plus, it matched a character from my favorite game in my past life.
Though she was a villain who died no matter the route.
Anyway, cool. Shaking my head slightly, obsidian-black hair cascaded softly. Thanks to the maids' loving care, it was as smooth as silk. Blood-red eyes oozed charisma, even at this age when I could just start toddling around. And above all.
I have horns too... The pair just starting to sprout from my head added dignity. Bonus: the small wings that popped out near my waist when I tensed my back. Black like my hair, featherless little things.
Demon wings...! Imagining spreading them wide one day and soaring through the skies made my chest swell.
"Miss, looking in the mirror again?"
A woman in a maid outfit entered through the door, asking. She was my personal maid... or something like that, I guessed. Always by my side caring for me, she could almost be seen as a second mom. Two moms? Nice.
At this moment, I decided to share my ambitious dream with her.
"Bella."
"Yes?"
"I'm gonna become the Demon King."
My name, Regina Diabolos, literally meant Queen of Demons. Maybe I was born to become the Demon King...?
Bella, hearing my dream, widened her eyes in surprise for a moment.
"That might be tough, miss...."
She said it with a somehow pitying expression.
"Huh? Why?"
"Because you're a succubus...."
Year 5 after birth. That's when I learned my race was succubus. I'd only just started accepting this female body, and now succubus...? And in that instant, memories flashed like lightning in my mind. Memories of Regina Diabolos from the dark fantasy game Dust Saga.
Wait, it's not just the name?
I'd really transmigrated? As that thought hit, I recalled Regina's fates across Dust Saga's countless routes.
"Hic...."
"Miss?!"
I fainted on the spot.
...Looking back, it was amazing I hadn't noticed until now. Same name, similar appearance—black hair, red eyes, everything. Or maybe I'd known deep down but denied reality. I knew all the ways Regina Diabolos died in Dust Saga. I just didn't want to believe I'd meet the same end.
And rightly so. In Dust Saga, Regina Diabolos was a mid-boss you had to kill to progress.
In the hidden route, she got a bit stronger, like a chapter boss.
Still, you had to kill her to advance. No matter the route, Regina was fated to die. Now I faced reality. No more denial—I needed a survival plan.
It's okay. Regina's a succubus, but her bloodline isn't bad. Her mother, Lilith, wasn't just any succubus; she was the pinnacle, the Succubus Queen. Her father was the Demon King, apex of all demons.
This black hair probably came from Dad.
Truth be told, I'd never even seen Dad once since birth. To the Demon King, Lilith was just one of many wives—a concubine. So, I was a concubine's child. Sounds decent so far, but not quite.
The worldview is too unique.Dust Saga's dark fantasy theme: humans and demons allied against otherworld invaders. To breed strong heirs for victory, the Demon King sowed his seed wildly—not just among demons, but all races. Humans, beastkin, elves, even dragons and spirits.
Ultimate player, huh. Including unmentioned characters, he probably had over 40 kids.
And in this world where munchkin dragon-demons die like weeds... A child of Succubus Queen and Demon King wasn't exceptional. Better than a plain human, maybe.
No, actually, it might be worse. Among demons, succubi vied for weakest. Physical strength barely above average humans. Powers? Passive pheromones for seduction and invading non-resistant targets' dreams. The Demon King's blood gave minimal growth potential, but...
"How did Regina grow in the hidden route?"
In novels, succubi got stronger sucking men's essence....
"Blech."
I imagined it. Just a few years ago, an ordinary guy—me having sex with another man? Unthinkable. Hidden route Regina probably grew that way too...
"Rejected."
I'd rather die. Shaking my head, I pondered long, then fell asleep. Still a kid's body. When I woke, one possibility dawned.
...Dreams. And the succubus innate ability to manipulate dreams. Combine those two... maybe that was possible?
