I wondered, with a heavy sense of irony, how my structured life had devolved into this.
Right now, I was sitting snugly on the lap of a remarkably beautiful woman. She was holding me close, her voice a soothing hum as she read a fairy tale with absolute devotion. She claimed to be my mother.
Think, Aahan! Think! How did a seasoned, forty-five-year-old man end up as a literal toddler?
...... Flashback ......
My name was Aahan Sharma. In my past life, I was the epitome of self-made success—a prominent entrepreneur navigating the hyper-advanced, sleek streets of Mumbai in the year 3000. I had a thriving business, a beautiful wife whom I cherished, and a brilliant teenage son who was currently conquering high school. Life was perfect. It was a well-crafted masterpiece of hard work and comfort.
Until that one morning.
It was precisely 7:00 AM. I was commuting to my corporate headquarters when my luxury vehicle suddenly suffered an unprecedented mechanical failure. Standard procedure: I called a technician, provided the coordinates, and assessed the distance. The office was only a short walk away, so I decided to cover the remaining blocks on foot.
I never made it to the lobby.
Out of nowhere, the roar of a stray truck shattered the morning air. Before I could even turn my head, it struck me with absolute, crushing force. The impact was deafening, snapping the thread of my consciousness instantly. The last fragments of my memory weren't of a hospital white ceiling, but the suffocating sound of a gathering crowd, the panicked murmurs of strangers, and the cold, mechanical clicking of smartphone cameras capturing my final moments.
Then, total blackness.
And now, here I was.
I had blinked, and suddenly found myself trapped inside the tiny, fragile body of a three-year-old child. The twenty-five-year-old woman cradling me was showering me with an overwhelming amount of maternal affection, completely invested in reciting a legendary lore about some ancient 'Demon King.'
Wait a minute. A Demon King? My mind raced, digging through old archives of my previous life. It sounded exactly like those Japanese Isekai cartoons—anime, as my son used to call them. I remember watching those strange shows with him back when he was in the sixth grade, right before he finally got serious about his academics. In those stories, the reincarnated protagonists always had tragic, miserable pasts—social outcasts or shut-ins who hated the world.
But why me? I wasn't some miserable soul looking for an escape! I was living a peaceful, incredibly carefree, and successful life. I had everything a man could ever desire. I was arguably one of the most fortunate people on Earth, and yet, my entire reality was erased in a fraction of a second.
Damn that truck driver. Couldn't they have just looked at the road?
A heavy, invisible sigh weighed down on my tiny chest. I wonder how my family is holding up right now... They must be devastated. A pang of genuine grief struck my heart, but logic quickly suppressed it. There was absolutely nothing I could do to alter my current situation. Coping was my only option.
First things first: I needed a strategy. I had to learn how to behave like an innocent child before this new family, decipher the rules of whatever universe or planet I had dropped into, and most importantly, understand the language.
Yet, as soon as that thought crossed my mind, a chilling realization hit me. Wait... I can understand every single word she is saying. How?
I glanced around the room. The decor was an unsettling blend of the archaic and the impossible. For instance, the very chair we were sitting on wasn't touching the floor—it was silently hovering in mid-air. Yeah, this is definitely an isekai world.
Suddenly, a sharp, electric jolt shot straight through my brain.
"Ah..." a tiny gasp escaped my lips.
It was an influx of foreign data. A rush of raw memories was aggressively binding itself to my adult consciousness, weaving into my own mind like a software update. The mystery of the language resolved itself instantly; my understanding wasn't magical, it was an instinctual residue left behind by this body.
As the memories settled, the puzzle pieces fell into place. This self-proclaimed mother was, in fact, biologically mine in this world. I also had a father and two older brothers. My father was the established chieftain of this entire settlement. My mother was primarily a homemaker, though she frequently assisted my father with administrative duties when required.
The memories also mentioned a 'clan.' I felt a familiar, cold bitterness tighten in my chest at that word. In my original life, my biological parents had tragically perished in a house fire when I was just fifteen. Not a single relative had stepped forward to offer a roof or a helping hand; they abandoned an orphaned teenager to the streets. It was through sheer grit, relentless part-time jobs, and sleepless nights that I funded my own education and built an empire from scratch, eventually marrying my college sweetheart. Consequently, I had a deep-seated, borderline allergic reaction to the concept of 'extended family.'
Setting my past trauma aside, I analyzed the new data. My new mother's name was Kurenai, and she was twenty-five. My father, Minami, was also twenty-five. They were exactly the same age.
Hold on. They are both significantly younger than my actual psychological age! The sheer awkwardness of the realization made my adult soul cringe. How on earth was I supposed to call people younger than my past-life self 'Mom' and 'Dad' without dying of pure embarrassment? And don't even get me started on having older brothers who were technically toddlers compared to my real age. What kind of cosmic joke was this?
Fortunately, the world's technological framework wasn't entirely primitive. According to the residual memories, they possessed motorized transport like cars, motorcycles, massive ships, and aircraft. Structurally, the designs mirrored the aesthetic of 1980s or 90s Earth, with architecture reminiscent of European style—sloping roofs and intricate, heavy timber frames. However, the core difference lay under the hood: everything here was fueled entirely by magic. In essence, their society was vastly more advanced than ours, operating on a completely different laws of physics.
"Kurayami! Kurayami, sweetie? What deep thoughts have you wandered into? Are you even listening to the story your beloved mother is telling you?"
The voice snapped me back to reality.
The woman possessed striking, midnight-black hair and matching obsidian eyes. She wore an elegant, sapphire-blue dress that flared out gracefully like a frock. She leaned down, her face inches from mine, peering into my eyes before crossing her arms and crossing her lips into an exaggerated, playful pout.
Kurayami. So that was my new name. And our family lineage was Sasaki.
Kurayami Sasaki. It sounded distinctly Japanese, likely feeling foreign only because of the linguistic transition. I stared up at her, my adult gears turning rapidly. Think. How does a normal, innocent three-year-old child respond to their mother without sounding like a seasoned CEO during a board meeting?
I forced my vocal cords to pitch higher, softening my expression into what I hoped looked like childhood wonder. "Huh? Oh! Yes, Mom! I'm listening. It's such an incredible story, I didn't want to miss a single second. Please, keep telling me, I'm really curious!"
Internally, I cursed myself. Damn it. The opening sentence was passable, but by the end of the pitch, I had accidentally slipped back into my corporate negotiation tone. It was over. A mother's intuition is lethal; she was going to realize her child had been replaced by an adult ghost.
Kurenai paused, staring at me for a heartbeat. Then, her face broke into a radiant, gentle smile. "Ha-ha! Well, I guess I have no choice then. If my little Kurayami is that invested, Mommy will tell you everything until the very end."
I let out a silent breath of relief. She hadn't caught on. The innocence of a parent's love had blinded her to the anomaly. However, this was a massive wake-up call—I couldn't let my guard down again. I had to master the art of being a child to protect this family's peace. I had tragically lost my original family, but these innocent people shouldn't have to lose their real son to a stranger's soul.
"Now, listen closely," Kurenai murmured, adjusting me on her lap as she turned the page.
I locked my gaze onto the illustrations, sharpening my focus. If I was going to survive in this magic-driven era, I needed to absorb every piece of information this world had to offer.
