The moon hung high in the Konoha sky, casting a silver glow over the small, shabby room of Satoru. In the eerie silence, a strange tension filled the air between two men—both from separate worlds, each carrying their own fate and burdens.
Under the cold moonlight of Konoha, Satoru turned his gaze toward Eren, the boy from a world of despair and endless bloodshed. His green eyes, once filled with fiery determination, now seemed hollow—like a man who had witnessed every horror life had to offer.
Satoru sighed, resting his chin on his hand while twirling the Yubashiri lightly across his lap. The system had assigned him the role of guiding this man… yet Eren didn't seem to care about any of it.
"Eren," he called out, his tone calm but firm.
The lifeless green eyes flickered toward him, without much emotion.
Satoru continued,
"I have a lot to tell you about this world. I assume the system already informed you that I'm your guide here, right? But… before that, I'm already thirty minutes late for a meeting with my students."
He smirked, attempting to lighten the mood.
"Do you want to come along? See what this world is like?"
Eren remained silent for a long time before finally giving a slight nod.

### Running Through the Trees – A Ninja and a Titan
Stepping out of the run-down apartment, the cool night air brushed against them, carrying the scent of damp earth and the rustling leaves.
Satoru bent his knees, channeling chakra into his feet before launching himself into the air, swiftly gliding across the treetops of Konoha.
At the same time, he activated his Observation Haki to its fullest extent, keeping a close watch on Eren, evaluating whether he could control his power.
At first, Eren looked startled by Satoru's sheer speed. He struggled to keep up, dashing along the ground, each step hitting hard like a sledgehammer. Unlike Satoru's smooth, near-weightless movements, Eren's footfalls were heavy, unrefined—like someone who had never practiced the art of light-footed movement before.

### A Titan's First Encounter with a Shinobi's Strength
In Eren's world, the strongest warriors relied on ODM gear to achieve high-speed mobility. But what he had just witnessed… was on another level.
Satoru wasn't using any external equipment.
No grappling hooks. No gas propulsion.
Just pure leg strength.
"Impossible…"
Eren clenched his teeth, his muscles tightening as he tried to match Satoru's pace.
---
### Overconfidence? Never Heard of It!
From a distance, Satoru monitored Eren's movements through his Observation Haki.
At first, Eren was clearly unaccustomed to the speed. His movements were clumsy, his landings wobbly—evidence that he had never encountered this kind of mobility before.
Satoru smirked to himself.
"Haha, Eren, I bet you're admiring a handsome, talented guy like me right now, huh?"
Feeling the need to impress, Satoru decided to turn up the style a notch.
He channeled more chakra into his legs, his figure flickering in and out like a ghost, each leap between the treetops as elegant as a dancer's waltz.
Under the moonlight, his white robe billowed, his sharp features glowing with a mysterious charm—an image of a master swordsman effortlessly weaving through the night.
If anyone else saw this, they'd probably think he was the fastest ninja in Konoha!

### A System's Judgment
The system, watching Satoru's exaggerated movements, finally spoke.
[System: "Satoru, I take back what I said about you having the aura of a great warrior. You are merely a great actor pretending to be one."]
[System: "10 out of 10 for performance. Recommendation: Reincarnation into Hollywood."]
Satoru: "…"
Nearly tripping over a branch, he almost fell face-first.
Satoru: "Shut up, system! I'm using my natural charm and unrivaled strength to inspire Eren! To pull him out of his despair! To make him admire me and strive to be like me! Got it, you old system fool?!"
*Ting! 50 points deducted.*
Satoru: "…"
The system had stolen his money again.
*Ting! 10 more points deducted.*
Satoru clenched his teeth.
"You just wait, I'll make you regret this someday!"

### The Awakening of a Primordial Power
Behind him, Eren was still struggling to keep up.
But then…
Something within him stirred.
A strange energy surged through his spine.
A wild force.
A primal instinct.
A sensation so familiar, yet so foreign.
It wasn't chakra.
It wasn't the Titan's power as he once knew it.
But it was something new.
Like an ancient beast had just been roused from its slumber within his veins.
It had no thoughts.
No emotions.
Only one instinct—
**SURVIVE.**
Under the moonlight, Eren's green eyes narrowed, his muscles coiling with latent power, his body trembling with newfound strength.
---
### A Swordsman's Concern
From the front, Satoru sensed it immediately.
His Observation Haki flared up as he focused on Eren's aura.
"A power just surged within him…"
His expression darkened.
"This isn't chakra."
Eren carried the spinal fluid of the Founding Titan.
Maybe… that was the key.
Maybe… the power of the Titans was beginning to evolve in this world.

### A Shinobi's Dilemma
Satoru kept watching closely.
Eren still had no control over this newfound energy.
It coursed through his body without any proper pathway or refinement.
If he continued like this, he would only be able to harness a fraction of its true potential.
Satoru began to hesitate.
Should he…
Teach Eren how to wield this power?
If he succeeded, Eren could rival the strongest Jinchūriki.
But if he lost control…
Satoru might be creating a true monster.
He had to be careful.
For now, he decided to observe further.
His eyes remained sharp as he leaped forward, leading the way toward the western forest, where three impatient students—Kakashi, Gai, and Obito—were waiting.
