Tsunade was furious—absolutely livid.
As the last direct descendant of the Senju clan and one of the Legendary Sannin, being toyed with by an Uchiha—of all people—was beyond humiliating.
The moment she recalled herself acting cute under transformation in front of Uchiha Byakuya, a cold fury surged through her veins. That shame quickly gave way to a singular, overpowering rage.
"You damned Uchiha bastard! You're dead!"
"I'm going to pulverize you!"
Without warning, Tsunade charged, chakra surging through her fists. Her punches, though seemingly simple, packed devastating force thanks to her precise chakra-enhanced strength—a technique that once sent the ground quaking and cracked giant summons with a single hit.
Byakuya didn't dare block directly. Even the slightest misjudgment could lead to shattered bones.
Still, with the help of his Sharingan, he deftly avoided her blows, his movements graceful and precise as he weaved between her strikes. And all the while, he couldn't help taunting her.
"Tsk, tsk… Is this the famed strength of the Senju clan? I expected more."
"Come on, Tsunade. Don't tell me that's all you've got?"
His words poured fuel on the fire.
"YOU—!" Tsunade's eyes burned with rage, veins pulsing on her forehead as she clenched her fists tighter.
"You're completely pissing me off, you smug little—"
The ground cracked beneath each of her punches, dust and debris flying as Byakuya narrowly avoided each blow.
"You talk big, but you're just dodging. What's wrong? Afraid my punches might ruin that pretty Uchiha face?"
But Byakuya grinned.
"You've got power, sure—but with a brain like yours, I wonder if all your nutrition just went to your chest..."
"YOU MISERABLE LITTLE—!"
Tsunade completely snapped.
Up until now, she'd shown restraint—barely. After all, Byakuya was a fellow Konoha shinobi. But now, there was no holding back.
[Ding! Tsunade's rage detected: +700 Negative Emotion Energy. Ninjutsu Proficiency +20]
[Ding! +800 Negative Emotion Energy. Taijutsu Proficiency +30]
[Ding! +900 Negative Emotion Energy. Genjutsu Proficiency +40]
"I'll show you exactly why people call me a monster!"
Tsunade leapt into the air with explosive force, chakra surging and focused into her heel.
"Heavenly Foot of Pain!"
With a thunderous crash, she struck the ground. The earth split apart from the impact, sending massive tremors and shards of rock in all directions.
Byakuya dodged again, though a few chunks of rubble scraped past him.
He smirked.
"You'll have to do better than—"
Suddenly, something tugged at his ankles. Black-inked characters slithered like serpents around his limbs—a sealing technique.
"When—!?"
Byakuya's eyes widened in shock as he realized the rubble scattered by her earlier impact had been marked with fūinjutsu, activated upon contact.
"Smart move..." he muttered, trying to twist free. But Tsunade stood above him now, smirking confidently.
"You didn't think all I knew was brute force, did you?"
Just then, Uchiha Mikoto stepped forward, prepared to assist.
"Byakuya-sama, I'll break the seal—"
"No need." Byakuya raised a hand, grinning despite being restrained. "This busty brute can't hurt me."
Tsunade twitched.
"What did you just say!?"
"I said you're all chest and no brains—"
"YOU INSOLENT LITTLE—!"
Her fist flew again, this time aiming not just to hurt—but to leave a crater where Byakuya once stood.
"Haha, I'll mess with whoever has the biggest chest!"
Byakuya smirked provocatively, his eyes fixed on Tsunade with deliberate malice.
"You damn Uchiha bastard! I'm going to smash that foul mouth of yours!"
Tsunade's fury reignited instantly. Though she had calmed slightly after suppressing Byakuya moments earlier, his crude words reignited her explosive temper.
With a snarl, Tsunade drove her chakra-enhanced fist toward Byakuya's chest, her legendary strength behind the blow. The air cracked as her punch tore through it, the shockwave alone enough to rattle the nearby trees. She didn't hold back—not even a little. She was confident enough in her medical ninjutsu to heal him afterward, if needed.
But would an Uchiha with Mangekyō Sharingan simply stand there and take it?
Of course not.
"Shinkōgan."
Just before her fist landed, Byakuya's body shimmered unnaturally—and in an instant, he vanished into a swirling distortion of space. Tsunade's punch met only air, the force of it blasting a crater into the ground behind him.
Freed from her chakra restraints, Byakuya reappeared a short distance away, smirking.
"What…? What did you just do?"
Tsunade stared at him, stunned. She had hit him—she was sure of it. Her chakra, precision, and speed had been perfect.
"Could it be… genjutsu?"
Her medical expertise kicked in as she scanned her chakra flow. No disruptions. No anomalies. No signs of illusion. She wasn't under a genjutsu.
"Want to know?" Byakuya said smugly, the Mangekyō Sharingan spinning in his eyes. "Too bad—I'm not telling you."
Tsunade narrowed her eyes. She had faced Mangekyō users before—Itachi, Shisui—and knew better than to underestimate them. But logic had long since given way to rage.
"I don't care what eye technique you're using," she growled. "Today, I'm going to cave in that smug face of yours!"
With another roar, Tsunade charged again, her fists brimming with destructive power.
