After spending the night with Uchiha Ryosuke, Yūgao Uzuki lay in silence, the weight of her decision settling in. She had done all she could — used every tool, even her body, to extract the truth behind Ryosuke's overwhelming power. And yet... she'd come away with more questions than answers.
As she quietly began redressing herself, her mind replayed the night again and again. Was it really just to complete the mission? Or had something inside her shifted?
Ryosuke, now fully awake, watched her with a trace of reluctance. "What's the rush?" he asked lazily, propping his arm behind his head. "I still have... another secret to share with you."
Yūgao paused mid-motion, her heart thudding. Could he really be planning to reveal the truth this time? She turned back toward him, cautious. "What secret?" she asked, trying to sound indifferent.
Ryosuke smirked and gestured for her to come closer. "Come here. I'll tell you."
She narrowed her eyes. That smirk was dangerous. Her instincts screamed this was a trap—but for the sake of the mission, and the elusive intel, she cautiously leaned in.
Predictably, she found herself swept into his arms again. Ryosuke grinned. "Trying to sneak away again?"
"You tricked me!" she snapped, struggling, though her strength hadn't fully recovered from the ordeal earlier.
"Trick you? Not at all," Ryosuke murmured, brushing his lips near her ear. "Actually, when I'm with you like this, my chakra... increases. It's one of the side effects of my body constitution."
Yūgao froze. "What...?" She blinked in disbelief. "You're saying having sex helps you build chakra?"
Ryosuke nodded solemnly. "Physical and spiritual energy form chakra. In my case, this kind of... intimacy boosts both. I'm serious."
Her thoughts crashed into a wall of cognitive dissonance. This man was either a world-class manipulator — or something fundamentally abnormal.
Chakra came from a balance of physical energy and mental focus. Sure, training and mental clarity could enhance it... but through sex?
It sounded like nonsense.
And yet, she couldn't deny the facts. She had witnessed his strength — superhuman reaction speed, monstrous chakra reserves, techniques that even elite Jonin struggled to execute. Was it truly possible that he possessed such a unique body constitution — one that transformed physical intimacy into raw chakra?
No way. It had to be a bluff. Probably something he told every kunoichi who came near. But then again… the way he toyed with her — like she wasn't even trying — and the confidence in his every move…
Could he be telling the truth?
Not that it mattered. Whatever relationship existed between them had ended with this mission. She was done being used — whether by Hiruzen Sarutobi, or by Ryosuke himself.
Still wrapped in thought, Yūgao tried to escape his arms again, only to realize he'd dozed off — fast asleep, still holding her gently.
She sighed, exasperated and exhausted, her muscles aching. She'd return to the Hokage, file her report, and put this madness behind her.
By afternoon, Yūgao had returned home and cleaned herself up thoroughly. Dressed again in her ANBU attire, she marched to the Hokage's office. Her nerves danced under her skin — not from guilt, but from doubt. What would she even say? That she'd slept with the man and his answer to unimaginable strength was "I just train a lot and also get stronger through sex"?
That wasn't a report — it was a punchline.
She stepped into the Hokage's chamber, bowing respectfully. Hiruzen Sarutobi looked up with a glimmer of anticipation. "Yūgao, you're back. Did you uncover anything useful?"
She nodded slowly. "Yes… though I'm unsure if it will make sense."
"Try me," the old man said. "What is his secret?"
Yūgao hesitated before speaking, unsure how to phrase what felt like a ridiculous answer. "Last night... I reached a level of intimacy with Uchiha Ryosuke. During that... moment, he revealed what he believes is the core of his strength."
She inhaled deeply, then said it straight:
"He claims to have a unique body constitution. According to him, he grows stronger every day just through regular training. What would take another ninja months or years to master, he can achieve in days. Additionally... he claims that sexual activity increases his chakra reserves."
Sarutobi blinked. The silence in the room was suffocating.
He leaned back in his chair, visibly disturbed, trying to process what he'd heard.
This... was not the answer he expected.
The Sandaime was a well-versed shinobi, a man who'd studied ninjutsu and chakra theory his entire life. Training, meditation, mental discipline — these were the accepted means of growth. But sex? As a method of chakra enhancement?
He found himself at a loss for words.
And yet… there was the undeniable truth: Ryosuke was growing stronger — rapidly. From what he'd gathered, the boy started as just another Uchiha under the wing of Might Guy. But now… he was frighteningly powerful — so much so that even the elite Jonin like Asuma struggled to keep up.
Could it be true?
If it was true, he'd unknowingly sent Yūgao to do nothing more than feed the enemy more strength.
And if it wasn't true?
Then Ryosuke had manipulated Yūgao effortlessly — even in bed — spinning a ridiculous story to keep her from prying deeper.
Both answers pointed to one thing: Ryosuke was dangerous.
Hiruzen leaned forward, face solemn. "Yūgao… you're relieved of this mission. There's no need to return to Ryosuke again."
Yūgao exhaled in relief, suppressing the shiver that ran down her spine at the memory. "Understood, Hokage-sama."
She bowed and departed, her heart caught between shame and confusion.
As the door shut behind her, Hiruzen sat in silence, stroking his beard.
Was this what the Uchiha Clan had become? A powerhouse with a monster like Ryosuke growing in secret? The boy trained every day, they said. Alone in the forest. Growing stronger in weeks than most did in years.
It reminded him of a time long gone — the golden age of shinobi. But also of something darker… someone like Ryosuke, unchecked, could eclipse even Madara Uchiha.
The Third Hokage sighed.
Even the Edo Tensei wouldn't help him now — he'd never dare face Hashirama or Tobirama with the choices he'd made regarding the Senju and Uchiha.
He feared it was already too late.
All the schemes in the world couldn't stop a man like Ryosuke.
Unless…
Unless the First Hokage himself returned from the grave.
And even that might not be enough.
