Kai didn't remember deciding to use the device again.
That was the first thing that unsettled him—not the way his fingers moved automatically to the hidden compartment beneath his bed, nor the faint hum that seemed to rise in anticipation as he touched the Neural Echo, but the absence of hesitation. A week ago, he would have paused. Questioned. Weighed the risk.
Now, the only thing he felt was a quiet, creeping certainty.
He needed it.
The room was dim, lit only by the soft glow of Lagos' restless night leaking through the blinds. Traffic murmured in the distance, horns and engines weaving into a familiar lullaby. But inside his head, there was something else—an emptiness that hadn't been there before. A gap. Like a word on the tip of his tongue that refused to surface.
Or something that had been taken.
Kai sat on the edge of his bed, the device resting in his palm. Smooth. Black. Almost warm, as if it recognized him.
"Just once," he muttered under his breath.
That was what he told himself every time.
The first deliberate use had changed everything.
Before, it had been accidental—glitches, fragments, flashes of foreign memories bleeding into his own. But now? Now he knew how to direct it. How to choose.
How to benefit.
He powered the device on, the faint blue interface flickering to life across its surface like liquid light. Names scrolled—profiles, identities, lives condensed into data signatures. Each one a person. Each one a doorway.
He hesitated for a fraction of a second.
Then he selected one.
SYNC INITIATED.
The world tilted.
He was standing in a cramped workshop, the smell of metal and oil thick in the air. His hands—no, not his hands—moved with practiced precision, tightening bolts, adjusting components, assembling something complex without conscious thought.
Knowledge flooded him.
Mechanical systems. Engine diagnostics. Improvisation with limited tools. Years of experience compressed into seconds, pouring into his brain like water into a cracked vessel.
Then—
He was back.
Kai gasped, collapsing forward, his palms hitting the floor. His heart pounded violently against his ribs, but beneath the shock was something else.
Clarity.
He looked around his room, but it didn't feel the same anymore. Objects stood out differently. The broken fan in the corner? He knew exactly what was wrong with it. The flickering lightbulb? A simple wiring issue. Even the cheap lock on his door—he could bypass it in seconds.
He laughed.
A short, breathless sound.
"This… this is insane."
But more importantly—
This was useful.
It started small.
Fixing things for neighbors. Charging just enough to seem reasonable but more than he'd ever made before. Word spread quickly. Kai became "the guy who could fix anything," the one people called when others failed.
He didn't correct them.
He didn't explain.
He just synced again.
And again.
And again.
Each session gave him something new.
A programmer's logic—clean, structured thinking that turned his old laptop into a gateway of possibilities. He learned to code overnight, fingers flying across the keyboard as if guided by muscle memory that wasn't his.
A negotiator's charm—subtle shifts in tone, body language, timing. Conversations became games he couldn't lose.
A fighter's instincts—sharp, reactive, precise. The world slowed when he needed it to.
It was like stacking lives on top of his own.
Layer by layer.
Skill by skill.
Until the old Kai—the one who struggled, who doubted, who hesitated—began to feel distant.
Irrelevant.
The money came next.
Not all at once, but steadily.
Repairs turned into contracts. Contracts turned into opportunities. With his newfound programming skills, Kai began taking freelance jobs online—fixing systems, building apps, solving problems for clients who had no idea they were dealing with someone who had learned everything in days.
He worked faster than anyone else.
Better than anyone else.
And he didn't sleep much anymore.
He didn't need to.
"Bro, how are you doing all this?"
The question came from Tunde, one of the few people Kai still spoke to regularly. They sat in a small roadside bar, plastic chairs creaking under their weight, the smell of grilled meat thick in the air.
Kai shrugged, taking a sip of his drink.
"I've just been… focused."
Tunde frowned. "Focused? You went from barely fixing your own phone to building software for foreign clients in like—what? Two weeks?"
Kai smiled faintly.
"People change."
"Not like this."
There was a pause.
Kai felt it then—a flicker of irritation. Sharp. Unfamiliar.
Or maybe it was familiar. Just not his.
"Why does it bother you?" Kai asked.
Tunde blinked, caught off guard. "It doesn't bother me. I'm just saying—it's weird."
Kai leaned back, studying him. For a moment, his mind split—multiple perspectives overlapping. One part of him analyzed Tunde's posture, his tone, micro-expressions. Another part calculated the most effective response to deflect suspicion.
"You worry too much," Kai said lightly. "I just got lucky."
Tunde didn't look convinced.
But he dropped it.
Kai used the device again that night.
And the night after that.
And the night after that.
Each time, the process felt smoother. Easier. Less overwhelming. Like his brain was adapting—expanding to accommodate the influx of чужие identities.
Or maybe it was breaking.
He didn't dwell on that thought.
What he did notice were the gaps.
At first, they were small.
Forgetting where he placed his keys. Losing track of conversations. Struggling to recall what he had done earlier in the day.
Normal things.
Explainable things.
But then—
He forgot his mother's voice.
Not completely. Just… the way it sounded when she laughed. The exact pitch, the warmth of it. He knew he should remember, but when he tried to reconstruct it, something felt off.
Like a corrupted file.
He froze, sitting alone in his room, the realization creeping in slowly.
"No," he whispered.
He closed his eyes, concentrating, trying to force the memory back into clarity.
Instead, something else surfaced.
A different voice.
Deeper. Rougher. Speaking in a language he didn't understand—but somehow felt.
Kai's eyes snapped open.
His breath came fast.
"That's not mine."
The words felt fragile.
Uncertain.
He should have stopped.
Any rational person would have.
But rationality had become… negotiable.
Because for every piece he lost—
He gained so much more.
The turning point came with the interview.
A major tech firm—one he had no business even applying to. But with the skills he'd accumulated, the knowledge stitched together from dozens of borrowed minds, Kai felt something dangerous.
Confidence.
He walked into the building like he belonged there.
Spoke like he had years of experience.
Answered questions before they were fully asked.
The interviewers exchanged glances, impressed, intrigued.
By the end of it, the job was his.
Just like that.
"You're overqualified," one of them had said, smiling.
Kai returned the smile.
If only they knew.
The job changed his life overnight.
Stable income. Status. Access to networks he had never even imagined.
But more importantly—
Access to better targets.
Because the Neural Echo wasn't limited to random profiles. With the right connections, the right data streams, Kai began to tap into something deeper. More specialized.
Doctors.
Engineers.
Strategists.
People at the top of their fields.
Each sync pushed him further.
Each sync made him sharper.
More capable.
More… something else.
He stopped thinking of it as borrowing.
That word felt too temporary.
Too harmless.
This wasn't borrowing.
This was integration.
One night, as he prepared for another session, he caught his reflection in the mirror.
For a moment, he didn't recognize himself.
Not physically—his face was the same. But his eyes…
They looked older.
Colder.
Like too many people were looking out from behind them.
Kai stepped closer.
"Who am I?" he asked quietly.
The question lingered in the air.
Unanswered.
The device pulsed softly in his hand.
Waiting.
Always waiting.
He should have put it down.
Walked away.
Tried to reclaim whatever pieces of himself were still intact.
But instead—
He activated it.
SYNC INITIATED.
This time, something felt different.
He wasn't just stepping into someone else's skills.
He was falling into their life.
Memories rushed in—not just functional knowledge, but emotions, experiences, fragments of identity that clung to him like shadows.
A childhood.
A failure.
A regret.
A name.
He saw it clearly.
Felt it.
Became it.
When he came back, he didn't move for a long time.
The room was silent.
Too silent.
Kai blinked slowly, his thoughts struggling to align.
Something was wrong.
Not physically.
Internally.
Like a boundary had been crossed.
He stood up unsteadily, walking to the mirror again.
His reflection stared back.
But for a split second—
It shifted.
Not visibly.
But perceptibly.
Like someone else was trying to surface.
Kai gripped the edge of the sink, his knuckles whitening.
"No," he said firmly.
"I'm still me."
But the words lacked conviction.
Because deep down—
He wasn't sure anymore.
The device had given him everything he wanted.
Skill.
Money.
Power.
Control.
But it had also taken something in return.
Something he hadn't fully accounted for.
Himself.
And the worst part?
He wasn't sure he wanted it back.
