Tokyo Metropolis, Beige City, Beige Town –
Teitan Elementary School, Grade 1, Class B
The sunlight spilled through the windows in warm golden beams, casting shadows across desks and making the lush leaves outside shimmer in the breeze. The peaceful view gave life to the otherwise mundane classroom.
At the second row from the window, a child in blue short sleeves rested their chin in a small palm, gaze fixed on a bird preening itself on a branch. Though young, their eyes were filled with a world-weariness, like one who had seen too much for their age.
The elegant teacher at the front of the class noticed her most brilliant yet least engaged student drifting again. With a subtle sigh, her refined features shifted to a soft smile. "Suzuki-san, what is seven times nine plus six?"
"Sixty-nine," came the immediate response—absent-minded, yet precise.
Gasps of amazement swept through the classroom like wind across a wheat field. Awe filled the eyes of classmates, each reacting as if a divine being of intellect had just spoken. Though this had become a daily occurrence, their enthusiasm never waned.
Suzuki Seimei, aloof yet peerless in intelligence, seemed to defy logic. Despite his lack of effort in class—often caught daydreaming or napping—his performance remained flawless. Every assignment: full marks. Every test: a perfect score. It was maddeningly admirable.
"Correct…" The teacher, Sumiko Kobayashi, forced a smile that didn't quite reach her tired eyes.
Honestly, can't this genius get something wrong for once? she lamented internally. He's too perfect—it makes me feel like a decoration in the classroom…
She turned away as Seimei continued to stare out the window, lost in thought. Despite her inner frustration, Sumiko harbored deep fondness for the child. If every student were as bright as Seimei, teaching would be a dream. Yet his overwhelming intelligence made her role feel almost meaningless.
Still… she mused. He's just a first-grader… isn't he?
Unaware of the internal battles he inspired, Suzuki Seimei continued to bask in the warmth of the sun, thoughts drifting far beyond his tiny frame.
"Life as an elementary student is dull, sure—but it's peaceful. No debts, no clients, no deadlines. Just sunlight, playgrounds, and free snacks." A small smile touched his lips as his memories wandered back to a past life long gone.
Because Suzuki Seimei was not like other children.
Once, he had lived in a very different world, one rooted in sweat and struggle. Born in the Eastern Nations, he'd lost his parents early and wandered into adulthood as a modest, unnoticed painter. Though passionate, he never reached fame—his work appreciated by few, his earnings barely enough for rent and brushes.
That life ended during an art excursion to the cliffs of Jiankou, where a careless step sent him plunging into darkness. Death came swiftly… and rebirth came unexpectedly.
The next thing he knew, he was an infant again—cradled in soft blankets, surrounded by wealth and warmth he had never known. This time, he had a name. A powerful name: Suzuki Seimei.
Born into the legendary Suzuki family—the same conglomerate backing the world-renowned Suzuki Financial Group—his life trajectory shifted drastically. No longer a starving artist, Seimei became heir to one of Japan's greatest fortunes. Not only did he have living parents, but also two older sisters: Suzuki Ayako and Suzuki Sonoko.
Through family chatter, he soon learned of a strange twist. Sonoko had classmates named Mori Ran and Kudo Shinichi—names Seimei instantly recognized.
No way… he had thought. Isn't this the world of Detective Conan?
His suspicions deepened when he encountered familiar faces. Professor Agasa walking down the street. The distinct posters of the Kaito Kid. Even the school uniform designs matched. He wasn't just in a different life. He was in a different universe.
He now lived in a hybrid realm, where the grounded criminal mysteries of Detective Conan subtly overlapped with the bizarre—rumors of shadowy organizations like the Black Org, whispers of strange child prodigies in strange bodies, and secrets hidden behind every alley. Yet strangely, he sensed more: anomalies in the atmosphere, the flow of chakra-like energies similar to Naruto, and rare individuals who exuded haki-like pressure from One Piece.
Still, Seimei found solace in the comfort of his second chance. Born into wealth. Loved by family. Respected in school. It was the very definition of a golden start.
There was just one caveat—he hadn't awakened a system. No cheat, no plug-in. No daily quests, no sign-in rewards. Despite all the isekai novels and manhua he'd consumed in his past life, Seimei seemed… ordinary in power.
But maybe that's the price of peace. Who needs a golden finger when you're already holding the gold?
The school bell rang sharply, pulling him back to the present.
"RIIIIING!"
Class ended in a burst of movement as children grabbed bags and darted outside like released Pokémon.
Before Seimei could reach the gate, three small figures blocked his path: Yoshida Ayumi, Tsuburaya Mitsuhiko, and Kojima Motota.
Wearing her signature orange dress, Ayumi approached shyly, eyes bright. "Seimei-kun, tomorrow's Saturday! We're going to Dorobika Paradise. Do you want to come with us?"
Kojima, ever the loudmouth, chimed in with a boastful grin. "You better say yes! Ayumi invited you herself. Don't be a jerk about it!"
Seimei raised a brow. Kojima's oversized frame and puffed-up bravado might scare other kids, but not him. I've seen pirates stare down admirals. You think a chubby kid can scare me?
Still… the sparkle in Ayumi's eyes made it hard to say no. Not that he wanted to. He definitely wasn't curious about the new haunted house expansion. Not at all.
"Alright, alright," he relented. "Let's meet at the entrance at 8 a.m."
"Yay! See you there, Seimei-kun!"
The trio dashed off, elated.
As Seimei walked toward the school's side alley, his mood lifted. He didn't know why, but something told him tomorrow wouldn't just be fun… it would be important.
A black van waited at the curb—sleek, tinted, unmarked.
Inside sat a sharp-eyed man in a black suit with a weathered, squared jaw: Inoue Ryuichi, his personal driver and bodyguard. Former JSDF special ops, now under private contract by the Suzuki family. Behind the wheel, calm and vigilant.
Though the Suzuki household raised their children with modesty, security remained non-negotiable. Especially for Seimei—the future of the entire group.
Seimei climbed in without a word.
Behind him, the sun began to dip over Beige Town… and somewhere in the shadows, two men in black suits watched through binoculars.
The game had already begun.
