Osaka felt different from Musutafu.
Not louder.
Not busier.
Just… sharper.
The streets carried a tension that wasn't obvious at first glance. People walked normally. Shops were open. Traffic moved the same way it did anywhere else.
But beneath it—
There was unease.
Ren noticed it the moment he stepped out of the station.
Not with his eyes.
But with the faint pressure at the edge of his awareness.
Negative emotion.
Not overwhelming.
But layered.
Frustration. Fear. Irritation. Suspicion.
More volatile than usual.
Exactly what he expected after Stain.
Ren adjusted the strap of his bag slightly as he walked down the sidewalk.
He hadn't come here as a hero.
He hadn't come here to fight.
He hadn't even come here to find Overhaul directly.
That would be stupid.
Instead—
He came to observe.
To let patterns reveal themselves.
Rooftops
It didn't take long before he left the main streets behind.
A narrow alley.
A rusted ladder.
A quick climb.
And then—
Open air.
Ren stepped onto the rooftop and exhaled slowly.
This was better.
Cleaner.
Quieter.
From up here, the city spread out in layers of concrete, steel, and shadowed gaps between buildings.
Perfect terrain.
He rolled his shoulders once.
Then moved.
Three steps forward.
A short sprint.
Jump.
His body lifted off the edge of the rooftop, clearing the gap cleanly.
He landed lightly on the next building, knees bending just enough to absorb the impact.
No wasted motion.
No hesitation.
Then he ran again.
Parkour wasn't something he had learned for combat.
It wasn't even something he had trained for a specific goal.
He just… liked it.
The rhythm.
The movement.
The constant adjustment.
Every jump was slightly different.
Every landing required awareness.
It forced him to stay present.
And for once—
His mind wasn't trying to calculate outcomes or plan ten steps ahead.
It was quiet.
Ren vaulted over a low wall and cut diagonally across a rooftop cluttered with vents and satellite dishes.
A small shift in weight.
A quick step onto a raised pipe.
Another jump.
The wind brushed past him as he crossed another gap.
He landed and kept moving.
There was no rush.
No pressure.
For the first time in a while—
He was just moving because he wanted to.
Then he slowed.
Not because he was tired.
But because something changed.
The Feeling
Ren stepped to the edge of the rooftop and looked down.
A narrow street.
Mostly empty.
A delivery truck parked halfway along the curb.
Two men standing near the back.
Nothing unusual.
At least visually.
But the air around them felt… wrong.
Not intense.
Not sharp like panic or fear.
Just—
Heavy.
Controlled.
Suppressed hostility.
Ren tilted his head slightly.
His ability didn't give him thoughts.
It didn't tell him what people were planning.
It only reflected emotional density.
And this—
This felt like something being contained.
He crouched slightly, resting one hand against the edge of the roof.
Watched.
Didn't move closer.
Didn't act.
Just observed.
One of the men knocked twice on the back of the truck.
A pause.
Then the door opened from inside.
Another figure stepped out briefly.
Words were exchanged.
Too quiet to hear.
Too normal to attract attention.
But the emotional pressure increased for just a moment—
Then flattened again.
Like a spike that had been quickly suppressed.
The door shut.
The truck engine started.
And just like that—
It was over.
The vehicle drove away.
The two men left in opposite directions.
No commotion.
No signs of conflict.
Nothing that would stand out to anyone passing by.
Ren stood slowly.
He didn't chase them.
Didn't follow the truck.
That wasn't the point.
Not yet.
He reached into his pocket and pulled out his phone.
Opened the camera.
Checked the recording.
Still running.
He had started it earlier, casually, without focusing on anything specific.
Now—
It had something.
Not proof.
Not evidence.
But a piece.
And pieces were enough.
Movement Again
Ren stepped back from the edge and moved again.
This time slower.
More deliberate.
He wasn't here to find Overhaul directly.
That would require luck.
Or force.
Neither were reliable.
Instead, he was building a trail.
Observations.
Patterns.
Moments that didn't quite fit.
Enough to justify attention.
Enough to point someone smarter, more connected—
In the right direction.
He crossed another rooftop, then dropped down a level using a fire escape.
Metal clanged softly under his weight.
He paused halfway down, listening.
Nothing.
Then continued.
Back in the alley, the city felt heavier again.
More enclosed.
More chaotic.
Ren walked for a few minutes, blending into the flow of people.
No one paid attention to him.
Just another student.
Just another passerby.
But his mind was working.
Not aggressively.
Not obsessively.
Just… noting.
That truck.
Those men.
That emotional spike.
It wasn't enough to conclude anything.
But it didn't need to be.
Ren turned a corner and glanced up briefly.
Another set of rooftops.
Another route.
He smirked faintly.
Then moved.
Freedom
He climbed again.
Quick.
Efficient.
Back into open space.
The city stretched out in front of him once more.
And without thinking too much about it—
He ran.
Jump.
Land.
Step.
Vault.
The rhythm returned instantly.
Clean.
Simple.
Unrestricted.
For all the complexity of his plans…
For all the calculations about the future…
This—
This part was easy.
Ren didn't need to control everything.
Didn't need perfect outcomes.
Didn't need certainty.
He just needed to keep moving.
Observe.
Adjust.
Act when necessary.
Another jump.
A longer one this time.
Wind rushing past his ears as he cleared the gap.
He landed harder than before, sliding slightly before stabilizing.
Then straightened.
Somewhere in this city—
Overhaul existed.
Working.
Planning.
Hidden.
Ren looked out across the skyline.
Calm.
Focused.
Unhurried.
"I'll find the path," he said quietly.
Not a promise.
Not a declaration.
Just a simple statement.
Then he turned—
And kept moving across the rooftops.
