Nobody spoke.
The rain filled the silence, tapping steadily against broken stone and pooled water and the collapsed edges of the building Juzo had been thrown through. Shizune stood with her hands clasped. Juzo watched. Finn waited.
After a long time, Tsunade said, "No."
Finn let out a slow breath through his nose. He didn't seem surprised.
"You're exactly as Jiraiya described," he said. "Not a flexible bone in you when you've made up your mind."
Tsunade's eyes sharpened at the name. "You know Jiraiya?"
"He's a friend."
"Then you should understand why asking me something like this is out of line."
"He's a friend," Finn said again, with patient emphasis. "He doesn't make my decisions for me, and I don't make his." He paused, and something honest moved across his face, a touch of genuine regret. "I had hoped we could resolve this between us in good faith. It seems that's not where we're landing."
Tsunade was already in motion before he finished the sentence.
She was not the kind of person who waited for a cleaner moment. When a situation was heading toward a fight, she went straight to the fight. Hesitation had never served her.
"Show me what gives you the nerve to stand there and say that to my face!"
Her fist came in hard and fast, center mass, the full weight of her body behind it. She hadn't been holding back against Juzo, and she didn't start now.
Finn didn't step aside.
He raised his open palm and caught the fist.
Tsunade's eyes went wide for a fraction of a second, the instinctive surprise of a person who has never once, across a career full of opponents, had someone meet a full-force strike with an empty hand. She pushed. Her chakra surged through the strike, adding to what was already enormous, the fist pressing against his palm with everything she had behind it.
The ground under Finn's feet didn't survive it. The stone fractured outward in a ring and then collapsed, Finn dropping half a step as the surface gave way beneath him. The rubble continued down, the compressed force driving it further, grinding gravel and soil into powder around his feet.
But Finn's feet found the next layer of ground and held there.
He hadn't moved.
Tsunade stared at the hand wrapped around her fist. The arm attached to it hadn't trembled. No white knuckles, no locked elbow absorbing the load. He was simply standing there, carrying her strike in one hand, looking at her with an expression of mild interest.
She knew, academically, that this shouldn't be possible. The supernatural strength of the Senju line wasn't a simple accumulation of physical force. Anyone could theorize about concentrating chakra into a single point of contact, and many had tried to reproduce the principle from that description alone. None of them had managed it, because that description was missing the essential piece. The technique's power scaled directly with the practitioner's chakra reserves. The more chakra in the body, the greater the force. It was not something that could be approximated on a modest foundation.
Tsunade had been born into one of the deepest reserves in the shinobi world. Her punch, without the Yin Seal, without releasing anything she was holding in reserve, was already categorically beyond ordinary output.
She had seen this technique flatten structures and send trained shinobi cartwheeling through walls. She had never, in her life, had it held.
Juzo, watching from his position near the rubble, laughed under his breath.
"My boss knocked the Three-Tails unconscious with a single punch," he said, to no one in particular. "You're not going to rattle him with one fist."
Finn was running his own assessment, quiet and internal. He registered the force, mapped it against what he knew.
It wasn't the raw tonnage of someone like Charlotte Linlin, or Garp in his prime. Those were forces of nature expressed through pure physical mass and will. Tsunade was something different. What she had was refinement. Every grain of force was directed, nothing dispersed, nothing wasted, the entire output arriving on a single point at the moment of contact. One hundred percent generated, one hundred percent delivered.
He didn't actually know how to do that. Not like this. It was a technique he didn't have, which made him take it seriously in a way that raw power alone might not have demanded.
Interesting.
"Is that it?" he said.
Her eyes flickered with something hot.
She pulled her arm back, and as she drew it in, her elbow changed trajectory, pushing outward, bringing her body closer to his in a single tight movement. The angle put them suddenly very close. Finn found his field of vision briefly, comprehensively occupied.
Ah.
Then her other fist was coming from the side, and that pulled his attention back to where it needed to be.
He blocked with his forearm, catching the strike along his arm rather than at the wrist. The impact was sharp and total, the sound wave from the collision pushing the rain outward in a brief ring of clear air around them, and the ground beneath cracked again, the fractures spreading outward in lines rather than a single collapse.
The diamond mark on Tsunade's forehead, the Yin Seal, began to move. The stored pattern spread outward from its center in faint lines, the seal beginning to open.
Finn moved first.
A thin current of lightning chakra ran through his body, not a technique, just the activation of the mode itself, speed and reaction lifting to a higher register. His arm came up, caught Tsunade's next incoming strike, and instead of blocking it, followed it inward, the motion turning her wrist and bringing her arm across her own body. He stepped into the space it created and trapped her arm under his, pinned against his side.
She was already reacting, trying to pull free, but his other hand had closed around the belt at her waist before she finished the thought.
He was aware, briefly, that the lightning chakra running through him was responsible for an inch of separation that otherwise wouldn't have existed. The fraction of a second the mode had taken to engage. He filed that observation and kept moving.
He had her weight, her position, her balance. He worked with all three.
Both hands shifted, one to her torso, one keeping her arm controlled. He turned her, the motion fast and complete, and she rotated with it involuntarily, the physics of her own weight working against her before she could redirect any chakra to compensate. Her center of mass inverted.
He lifted her, drove downward, and put her into the ground.
"Thunder Bomb."
The lightning chakra discharged on impact, a full-body detonation that ran through the ground in every direction at once, the wave lifting stone and scattered rubble wherever it passed. The crater was immediate and total. Shizune threw an arm across her face against the spray.
The one thing Finn noticed, in the fraction of a second before the crash: a small pulse of chakra, and smoke.
He felt the weight shift wrong just before contact. Not Tsunade's mass under his hands but something softer, larger. The smoke rose, which was strange given the rain; summoning releases produced it regardless of weather.
The debris settled. The smoke cleared.
A slug the size of a small boat sat in the crater, its body slowly contracting where the impact had compressed it. Tsunade's form erupted from the creature's side a moment later, landing ten meters back with two smooth rotations through the air before her feet touched down.
She stumbled on landing. One foot caught, the other didn't, and she caught herself with a hand on the broken ground.
She pressed her other hand to her chest and coughed. A thin line of blood came with it, dark and wet against the rain-soaked stone. Her breathing was elevated, coming in visible pulls, the Yin Seal already working beneath the surface, channeling stored chakra toward the damage.
The blood on her lips, her own blood visible on her hand, registered. Her eyes dropped to it for a moment and she looked away, something tightening in her jaw.
Even through the slug's intervention, the impact had transmitted. She was hurt.
She breathed out through her nose and lifted her eyes to Finn.
The assessment in them was different now from what it had been at the start. Less skepticism, more pure attention.
"Have you reconsidered?" Finn asked.
Tsunade's hands formed seals.
The puddles scattered across the ruined street stirred. Water condensed and gathered, the small reservoirs drawing upward and compressing, and then several projectiles launched simultaneously from multiple angles, dense and fast, driven by concentrated chakra.
"Water Style: Water Bullet Technique."
Finn raised one arm.
The force moved outward from his center without visible effort, a repelling pressure that caught the incoming projectiles and reversed their momentum, the water bullets detonating in the air between them in a spread of fine mist.
"Slug."
The slug in the crater responded to Tsunade's voice immediately. It oriented toward Finn and its throat worked, a deep internal churning producing something that moved differently from water. The spray that came out was thick and yellowish, and it moved with the particular deliberate slowness of something very dense.
It hit the lightning chakra running across Finn's skin and the armor dissolved. Not deflected, not absorbed. The protective layer simply came apart where the acid contacted it, the slug's gastric secretions dissolving the chakra construct the same way they would dissolve stone.
Tsunade's expression shifted toward something that might have been momentum.
Then the black came.
It rose from the lower half of Finn's body without announcement, not quite a smoke and not quite a liquid, a dim absorption field that swallowed light in the space it occupied. The acid touched it and stopped. The spread ceased. The corrosive material vanished into the field as though it had never existed.
Tsunade's eyes narrowed, working the problem, trying to categorize what she was looking at.
She didn't get long.
The lightning moved first. A single flash, the displacement of air and chakra that preceded the Thunder Body Instant, and then Finn was no longer three meters away. He was directly in front of her. His hand closed around her throat before she completed the thought that preceded the reflex.
Her feet left the ground.
He held her there, one arm extended, her weight hanging from his grip with no visible strain. Her hands went immediately to his forearm, fingers finding the purchase points for a break, looking for the leverage a medical ninja would know to find. She couldn't generate the angle from this position.
Finn looked past her to Shizune.
Shizune had not moved. Her hands were pressed together in front of her, knuckles white, the small piglet under her arm pressed against her side.
"If I break her neck," Finn said, conversationally, "can the Hundred Healings Technique reverse that? I genuinely don't know the answer." He paused. "I'd rather not find out. If you feel the same way, Miss Shizune, I'd appreciate having this conversation about the Secret Art of Spiritualization now."
