Naruto: Wooing Tsunade from Day One!

"You do your best, and I'll provide support," Seven-Tails said confidently, channeling a massive amount of chakra into Tsunade. The seal housing the beast flapped its wings, observing the battle with interest. Tsunade, however, paid no attention to the Tailed Beast's enthusiasm.

As they marched forward, she transformed once again into the Tailed Beast's chakra cloak, a form she was well-acquainted with for combat. Activating the Strength of a Hundred Technique, her body became covered in Cursed Seals. Facing the full form of a Tailed Beast demanded nothing less than her utmost strength. Her fists glowed with crimson Tailed Beast Chakra as she flapped her wings, charging directly at Shukaku.

"Wind Release: Drilling Air Bullet!" Shukaku's massive arm slapped his round belly, launching a chakra-laden windball at Tsunade.

With incredible agility, Tsunade avoided the attack and countered with a powerful punch to Shukaku's head.

"Haha! You can't break my defenses," Shukaku boasted through Bunpuku, raising an arm to block the strike.

Bang!!

Tsunade's fist shattered Shukaku's arm, sending shards of sand flying.

"Well done!" Seven-Tails cheered from within, his excitement mirroring the thrill of landing the blow himself.

"Ah~!" Shukaku roared in fury, his pride wounded by the devastating punch. "This woman has so much strength," he muttered, seething.

"Don't interfere with me," Bunpuku's voice interrupted, struggling to maintain control.

In retaliation, Shukaku's sand latched onto Tsunade's arm, creeping along her body to trap her.

"Heavenly Foot of Pain!" Tsunade roared, shattering Shukaku's arm with a devastating kick and freeing herself from the sand's grip. Flapping her wings, she ascended high into the sky, scanning for weaknesses in Shukaku's form.

Enraged, Shukaku unleashed a flurry of Air Bullets at Tsunade, but her agile maneuvers kept her out of harm's way. Even as her arm sustained damage, it regenerated swiftly, a testament to her resilience.

Meanwhile, Pakura and her shadow guards clashed with Sakumo, while the Suna and Konoha shinobi fought furiously at a distance. Both sides instinctively avoided the destructive battle between the Jinchūriki.

On the battlefield, Shukaku's rage intensified. He extended his massive arms, attempting to grab Tsunade, but she skillfully evaded, darting past his defenses. She capitalized on an opening, landing a powerful punch to Shukaku's abdomen. The impact left a deep crater in his body, though the sand rapidly restored itself.

Shukaku retaliated by retracting his arm, but Tsunade once again dodged.

Seeing her attacks fail to inflict lasting damage, Tsunade grew anxious. "Does Shukaku have any weaknesses?" she asked sharply.

"You're asking me?" The Seven-Tails replied, momentarily stunned by her sudden question. After rambling to himself throughout the battle, he hadn't expected her to engage him.

"What do you think?" Tsunade snapped, her tone implying that if they weren't in the middle of a battle, she'd likely march over and punch him too.

"Er, Shukaku's weak point is at the root of his tail," Seven-Tails finally answered, his words layered with meaning.

"The anus?" Tsunade asked bluntly, her experience as a Medical-nin making her unflinching about such anatomy.

"Mm-hmm," Seven-Tails affirmed. "Back then, Nine-Tails took him down with one strike by—"

But before he could elaborate further, Tsunade tuned him out. The essential information had been extracted. Spreading her wings, she launched herself back into the fight with renewed determination.

Her small, agile frame darted around Shukaku's massive body, leaving him on the defensive. His lumbering attacks failed to land as her swift movements outpaced him entirely. It was clear that Bunpuku's control over the rampaging beast was slipping.

"I'm going to kill you!" Shukaku roared, his fury boiling over. Raising his hands high, he conjured a massive boulder from sand and chakra, preparing to crush Tsunade. As she maneuvered to attack, his tail blocked her path, trapping her. The enormous shadow of the boulder loomed over her.

"Run! You're going to be smashed to bits!" Seven-Tails warned frantically.

"Cut the crap," Tsunade shot back, her voice steely. "Gate of Healing, open!"

By mastering Taijutsu and unlocking the Eight Inner Gates, Tsunade had gained access to two gates. Though not yet a master, her strength and speed surged, far surpassing her previous limits. The multiple layers of buffs she now carried made her output devastating.

With a fierce cry, "Ahhh!" she pushed past her limits.

Shukaku's cruel grin faltered as he prepared to crush her with the massive boulder. Before it could make contact, an explosion of crimson energy obliterated the rock, sending shards flying. A radiant figure soared into the air, propelled by overwhelming power.

Tsunade's punch struck Shukaku's face with cataclysmic force, shattering half of it into sand and leaving the beast reeling.

"Why is this woman's power getting stronger?" Shukaku growled, his frustration evident as the pits on his face began to slowly regenerate. His massive jaws opened wide, forming another Tailed Beast Ball.

"Impressive," Chōmei remarked from within Tsunade, watching her fight.

"I'd have died several times over if I were relying on you." Tsunade muttered under her breath and transitioned into her Half-Tailed Beast state. She knew the limitations of her Chakra Coat form—Tailed Beast Balls were impossible in that state.

The two Tailed Beast Balls collided once again, forcing the Suna and Konoha ninja to retreat further away from the battlefield.

It would be tragic to die from a Tailed Beast Ball and not from an enemy, after all.

"Multiple Shadow Clone Technique."

After Tsunade released her half-Tailed Beast form, hundreds of clones identical to her appeared across the field. Each one was formidable, with Chakra being recklessly expended to overwhelm her opponent.

Faced with the relentless assault of so many Tsunades, Shukaku was momentarily overwhelmed, struggling to defend himself. In mere moments, his body was riddled with wounds.

"Ah~" Shukaku groaned impatiently as he flailed his limbs wildly, scattering numerous Shadow Clones with each swing.

"Sand Release: Sand Waterfall Funeral," he bellowed, forming a hand seal. A massive wave of sand surged across the battlefield, sweeping away countless Tsunades like a tidal wave.

Bang bang bang...

As the dust settled, only about a dozen of Tsunade's clones remained standing.

"It really is tough," Tsunade muttered under her breath. Her injuries had already healed, a testament to her regenerative abilities.

"Secret Technique: Hiding in Scale Powder Technique!"

The remaining clones scattered across the battlefield, releasing large quantities of scale powder into the air. The powder obscured Shukaku's vision, slowing his movements.

"Now's the time. Attack!" Tsunade's main body gave the order, and the clones charged in unison.

Together, they managed to momentarily immobilize Shukaku, restraining his hands and tail.

Seizing the opportunity, Tsunade's main body flapped her wings and flew to the root of Shukaku's tail. With a massive amount of Chakra condensed into her feet, she unleashed her ultimate move.

"Heavenly Spear Foot!"

Her attack struck Shukaku with overwhelming force, sending him hurtling into the air. The enormous Chakra within her kick detonated upon impact, leaving half of Shukaku's body reduced to a pool of mud.

"Ow~"

Shukaku howled in pain after being seriously injured by the devastating blow, his cries echoing as he landed heavily on the ground.

"Chōmei, it must be you, you blabbermouth! Exposing my weakness," he growled angrily, his voice laced with frustration.

Tsunade, unwilling to let the opportunity slip away, took full advantage of Shukaku's vulnerable state. She and her clones surged forward to press the attack. If they could eliminate Shukaku's Jinchūriki here, the battle would be as good as won.

"Sand-Style: Shield of Sand!"

Shukaku, enduring the searing pain, began to shrink his massive form. Sand from his body swirled around him, forming a solid circular barrier. Tsunade's relentless strikes pounded against the sand shield, creating craters that quickly repaired themselves. Despite her best efforts, she was unable to break through and reach Shukaku's body.

His defense had become an impenetrable fortress, leaving Tsunade frustrated as she stared at the turtle-shell-like barrier.

"How do I fight this?" she muttered, her tone tinged with irritation.

"The tanuki claims to have the strongest shield. There's nothing I can do about this move."

"Why don't you try firing a shot?" Chōmei suggested hesitantly, unsure if a Tailed Beast Ball would be effective against Shukaku's defense.

"Forget it," Tsunade replied, shaking her head. "In terms of single damage, your shot doesn't compare to my fist."

With her refusal, the fight reached a stalemate.

Inside the turtle shell, Shukaku shared her frustration. His form had diminished, and his Jinchūriki, Bunpuku, had already reverted to his human state. Sitting cross-legged within the barrier, blood dripped from the corner of Bunpuku's mouth. It was clear that his body could no longer withstand such a punishing battle.

"That violent woman… I'm going to tear her apart," Shukaku snarled, his rage bubbling over.

"Shut up!" Bunpuku snapped, his patience finally wearing thin. "Look at the state you're in after being beaten up, and you still have the nerve to say that!"

Even Bunpuku, known for his calm temperament, couldn't tolerate Shukaku's incessant complaints. After all, taking hits from Tsunade felt no different from being struck by pure devastation.
