So… I was transmigrated into this world.
Hiro Nakamura stood in front of the mirror, gazing into his reflection—a super cute eight-year-old boy with snowy white hair streaked with black and purple on the right side, and violet-purple eyes.
"Is this... little Arlecchino? Also known as The Knave, or Father, in Genshin Impact?" he muttered with a soft smirk.
But no matter how surreal it felt, everything around him screamed modern-day Earth.
His family was rich—like, generationally wealthy. Even his grandparents owned one of the biggest tech companies in Japan, specializing in biotechnology and robotics. Sure, their base was Japan-only, but they occasionally partnered with foreign companies.
And now it was owned by Dad. As for Mom—she was a novelist, one of the best in Japan. Many of her works have been adapted into anime and games.
The last thing he remembered was… Truck-kun. Classic.
After that, things got fuzzy. His name, his past—gone. What remained was a mountain of otaku knowledge, anime, and games. No memories of people's faces, no clue which country he originally lived in, not even the flag.
And yet… he remembered being an introverted student. Which is why I focused on studying. I became a top-ten student in school and top ten in college—not the best, but still someone. But all that knowledge? It was probably just enough to get him through high school here.
Why? Because this world… was a bit more advanced than the Earth I lived in.
The kid he reincarnated into didn't seem talented. Sure, he was top of his class, but that was just the leftover knowledge from his past life doing the heavy lifting. And it seemed that Mom and Dad weren't tutoring me—but from time to time, they would teach me things related to their work.
But today was different.
Today, his two lives' memories—the old him and the new him—merged. The memories finally aligned.

[Rewards include: Templates, Talents, Property. System Space is unlimited—but can only store system-related products.]
"Great… I've got a system."
Information flooded into his mind like a tsunami. Two systems had clashed and nearly destroyed each other—but fragments of both fused, and from that chaos, this unique system was born.
The aftermath wasn't pretty—his soul was damaged in the process. But thanks to the strength of having lived two full lives, he survived.
"I see… so that's why my memories returned only today."
"Hey system… do I have a beginner pack?"
[Yes, Host. Would you like to open it now?]
"YES! Open, open!!"
[ Beginner Pack successfully opened.
Congratulations, Host. You've obtained:

"Damn… A genetically modified super-assassin and a child prodigy from Big Hero 6? That's the real jackpot..."
Maste Dual gives the same as the game in my last life with my desk in it as interface that can be accessed.
I have about 8000 dual cards, and every monster card has Dual Spirit
The system explained that talents came in levels: Common > Uncommon > Rare > Legendary > God. Ten of the same rarity could fuse into one of the next tier. The same went for templates—two templates with similar classes could merge into even more powerful ones.
Because the two original systems had fused, it was now possible to acquire both magical templates and overpowered skill systems.
"Alright… let's see the templates and integrate them."
He tapped the system interface. First up: Agent 47.

"Alright then… let's integrate these templates."
...
His fingers—still small and soft, the hands of an eight-year-old—trembled slightly as he tapped the [Integrate] button beneath Agent 47.
[Initiating Template Integration: Agent 47
Warning: This process will synchronize combat knowledge, physical conditioning, and core instincts with the Host's body and soul.
Proceed?]
"Proceed."
The moment he confirmed, a cold shockwave flooded his spine—like liquid nitrogen being poured directly into his body.
His muscles tensed. Bones trembled. His breath hitched.
The floor beneath him seemed to vanish as his mind spiraled into darkness.
He was no longer in his room.
He stood in a shadowed hallway, dressed in a black tailored suit. The world around him was grayscale and eerily silent.
A briefcase in hand. A fiber wire gripped tightly.
He became Agent 47.
He felt the weight of every silent kill, the muscle memory of a thousand precise strikes, the deep, terrifying calm of a man who could end a life without blinking.
Hiro's heart felt like it had stopped—but his mind was wide awake. Cold. Calculated. He could feel it. The killer instinct was settling into his DNA.
I felt I could do so many impossible moves—blending into crowds, infiltrating any facility, fighting with CQC, Judo, Karate. Using all types of firearms. And not just that—languages flowed naturally: English, Russian, Chinese, and more. Winemaking. Driving. Mechanics.
When he blinked, he was back. Kneeling on the floor of his bedroom. Sweat soaked his pajamas. His vision swam.
But he was alive.
And stronger.

"That was... intense. Hey system, why are there more skills than what showed up in the template?"
[Templates have Full Detailed and Basic Details interfaces. Full Detailed shows all skills you'll get. Basic only shows those that can be merged with other templates.]
I see.
His voice came out hoarse.
"Now… Hiro Hamada."
He pressed [Integrate] on the second template.
[Initiating Template Integration: Hiro Hamada
Warning: Neural Synchronization with Genius-level AI Architect and Real-Time Engineer. Host's brain will undergo temporary overclocking. Proceed?]
"Proceed."
This time, the sensation was different. It was mental.
His brain felt like it was being fed data at the speed of light. Algorithms, schematics, thousands of robotics blueprints, coding languages, engineering techniques, AI behavior patterns, and swarm intelligence control… all of it downloaded in seconds.
(I don't even understand, so don't ask.)
Hiro clutched his head, falling backward onto his bed, gasping.
Then suddenly—he saw it. A fully assembled microbot swarm design. A blueprint for a quantum computer. An AI assistant. Detailed specs for miniature flying drones in the ear.
No, I think it's in my mind.
Every wire, every line of code, every circuit—clear.
His eyes snapped open, glowing faint purple for just a moment before fading. His breathing slowed.
[Integration Complete: Hiro Hamada Template
You acquired: Robotics Mastery, Real-Time Engineering, and Genius-Level Intellect.

"...Damn. This is cool."
He sat up slowly, wiping the sweat from his brow. His hands shook—not from fear, but from excitement.
...
Hiro exhaled, still riding the rush from integrating two powerful templates. He leaned back on the bed, his heart slowly calming, sweat cooling on his skin.
Then—
[Legendary Talent Activation: Game Development
Would you like to synchronize this talent with your mind, creativity network, and emotional center?
Warning: Awakening a Legendary-level Talent may temporarily induce time-dilation, hallucination.]
"Huh? Bring it on."
He clicked [Accept] without hesitation.
Suddenly, his surroundings shattered.
Like pixels breaking apart, his bedroom dissolved into glowing blue code. He was floating—weightless—in a digital world that looked like something between Tron and SAO.
He saw menus, HUDs, event flags, dialogue triggers.
Code danced across his eyes. Systems unfolded in his mind with perfect clarity.
A world builder loaded before him.
He reached out. His hand touched a blank screen—then with a thought, it transformed. Character models appeared. Level maps. Loot tables. UI animations. Dialogue scripting. Branching narrative logic. Enemy AI. Skill trees.
"...This isn't a system. This is a game engine designed by my mind... just like Unity or Unreal."
The void cracked—fractured like glass—and time snapped back into place.
He jolted upright in his bed, lungs gasping for air, heart pounding like a drum.
But his mind was crystal clear.
A thousand game engines. A million design tricks. Storytelling frameworks. Monetization models. UI best practices.
And most importantly, the creative hunger to build worlds.
"Really, I want to make a game so bad now."
He slowly opened his hands and smiled.

I always wanted to be a game dev in my past life as a CS graduate, but I didn't finish college… and died.
As far as I know, this world's entertainment is far from the same as my old one. Or it has abomination mixes.
Like One Piece? Doesn't exist. But a counterpart abomination exists—calling it "fairly passable" is an overstatement.
The name?
Just judge for yourself: Bamboo Hat Pirate Adventure.
With only about 60 episodes, and the anime production stopped, I'll have to bring the real version to this world if I have time in the future.
But for now...
