The shockwave erupted from the approaching pirate ship before anyone had properly finished registering its scale.
Zephyr watched it come across the water and tilted his head with the evaluating expression of an instructor calibrating a new variable. "About one-third of Whitebeard's presence," he said. "Maybe slightly more."
Behind the two of them, Ace had shifted his weight forward and opened his mouth. Whatever he had been about to say, he didn't get to say it.
Gion glanced at him first. She wasn't smiling exactly, but there was something easy in her expression, the kind of ease that comes from accurate self-assessment rather than performance. "Can you hold that?"
Ace looked at the incoming wave. He looked at the distance. He did the math.
"No," he said.
He hadn't even finished the word.
Gion stretched one arm out toward the shockwave, and lightning gathered around it. Not slow, not building up with visible effort: it was simply there when she asked for it, two silver arcs spiraling around her forearm and coiling at her palm before she extended her fingers and let them go.
The beam struck the shockwave dead center.
In the instant of contact, the shockwave came apart. Not deflected, not scattered gradually: it shattered, the pressure front breaking into pieces that spread sideways across the water in diminishing lines, none of them carrying enough force to reach the warship's hull. The lightning beam continued through the space where the shockwave had been, crossing the distance to the pirate ship and striking its hull with a crack that left the wood scorched and the rigging sparking.
On the pirate ship, Bakkin had already arrived at a very specific and very unpleasant conclusion.
She knew that frequency. She knew the precise quality of controlled electrical force applied at that level of accuracy. The Rumble-Rumble Fruit was not a common ability, and the Marine's single user of it had built that control into something with a particular signature. It took her less than a second to put the lightning to a name.
Momousagi Gion. Thunder Swordsman. Admiral candidate. The woman who had engaged Kaido in the New World and returned with her limbs intact.
"Weevil!" The urgency in Bakkin's voice was real. "Block the lightning, we're leaving! Now!"
Weevil didn't know what his mother was afraid of and didn't particularly care. He knew what she needed him to do. He flipped the naginata in his grip and brought it around in a sweeping arc to meet the residual lightning rolling across the water toward them. The slash had the kinetic force behind it that had scattered the cannon volley earlier, and it was enough to break up the electrical column, dispersing it into branching lines across his blade.
The pirate ship began to turn.
Before Weevil could retract the sword, someone was standing behind him who had not been there before.
Gion stood between Weevil and Bakkin. Justice cloak settled at her shoulders with the residual motion of having moved across open ocean in a fraction of a second. Konpira hanging at her hip with one hand resting near the grip. She looked at Bakkin with the particular expression of someone who has already decided the answer to a question and is giving the other party the chance to arrive at it themselves before it has to be demonstrated.
"What do you think this is?" she said. "You don't just get to leave."
Bakkin had not processed how Gion had crossed the water. The ship had been moving. There had been no visible motion. One moment the Marine warship was at a distance; the next, this woman was standing on their deck as if she had always been there and the rest of reality had briefly displaced itself around her.
"Weevil!!!" Bakkin shouted.
Weevil's fighting instincts engaged before his mind did, which was generally how they operated. He didn't turn to look. He swept the naginata backward in a flat arc at shoulder height, Armament Haki already coating the blade, the swing carrying everything he had.
Gion was no longer behind him.
She was in front of Bakkin.
Konpira left the scabbard in a motion the eye couldn't follow. A flash of light on the blade, lightning fracturing along the edge in the instant before it moved. The sheath clicked shut. The sound came a half-second after everything else had already resolved.
Bakkin looked down.
The wound in her chest was not large. It was precise. The edges were scorched the specific dark color that lightning leaves when it passes through flesh rather than around it, a small perfect hole over her heart where the tip had gone through. She became aware of it in the same moment she became aware that breathing had become much more complicated than it had been before.
"Cough..." Her mouth was already filling with blood. She looked at Gion and the words she'd been going to say, whatever claim she'd planned to make about whose legacy she controlled, formed in the back of her throat and didn't make it out. "White...beard..."
The deck came up.
She didn't finish.
Weevil turned around.
The processing took a moment. His mother was lying on the deck. There was blood. He looked at this for a long moment, and then something that didn't have a name opened in the center of him and came out as sound.
"Mom!!!"
He crossed the deck in two strides and brought the naginata down with everything he had, the technique completely gone, no skill involved, nothing remaining but the specific grief of someone who has exactly one thing they care about and has just lost it. The blade was enormous and the force behind it was enormous and none of it mattered to Gion in any practical sense.
She stepped aside with the unhurried quality of water moving around stone.
Weevil struck at where she had been. He struck again. He struck again. The pirate ship's deck took significant damage. A section of railing came apart. A hatch cover disintegrated. He was destroying his own ship in the process of trying to reach someone who kept not being where his sword went.
"I'm not your enemy," Gion said. Not unkindly. Just as a statement of available fact. "She pointed you at us and you went without asking why. That's the whole of it."
He swung again.
She caught it on Konpira with her thunder-armored forearm braced behind the blade, stopping it cold. The impact sent a visible shudder through the ship's hull; the deck planking beneath them groaned. Weevil was genuinely strong in ways that didn't fully translate through reputation until force was actually exchanged.
"I will kill you!" he roared, and swung again.
She stepped out of the swing and let him go past.
"Thunder Dance: Thousand Cascades."
It was not a large declaration. The name arrived with the quality of something she had used often enough that the preamble had been worn smooth. Lightning saturated the air around her, and her figure multiplied: three images of Gion standing around Weevil, each holding Konpira, each occupying a different angle. Even Weevil's instincts couldn't resolve which was real, because the answer was that the question was wrong.
Three strikes came simultaneously.
Left, right, center. The impacts were placed with precision that had nothing to do with power and everything to do with understanding exactly where force becomes irrelevant regardless of how much resistance is behind it. The three wounds opened in the same instant the three figures became lightning and dispersed.
Gion was standing behind Weevil. She hadn't moved. She had simply been in three places and was now in one again.
She looked at his back with something close to genuine curiosity. "You have real power," she said. "But you've never been taught anything useful with it."
Weevil turned around.
His eyes were still red. His face was still wet. Whatever was happening behind them had not changed and was not going to change based on what she said or didn't say. He raised the naginata with both hands, made one of his wounds worse in the process without appearing to notice, and swung.
Gion moved with him this time, inside the arc of the blade, not against it. She moved the way a tide moves against the shore: not violently, just continuously, finding every gap he offered because a man who cannot think about what he is doing offers a great many gaps.
The pirate ship continued to come apart around them.
Then she stopped moving and lifted Konpira.
Through the space between his guard and his grief she put the point of the blade exactly where she had calculated it would do what she needed it to do.
"Pierce him: Thunderbird."
The lightning didn't spread. It focused. A single condensed beam poured down the length of Konpira and out through the tip, drilling through Weevil, through the ship behind him, through the mast, dissipating finally into the sky in a dazzling column that scattered the clouds above in a spreading circle.
Weevil stopped.
His mouth opened. Blood came out with his breath, and blood foam with the breath after. He looked down at the hole in his chest: fist-sized, the flesh around it scorched black and still smoking, where his heart had been before lightning moved through it.
Then he looked up at Gion.
The resentment in his eyes had not gone anywhere. The grief had not gone anywhere. Whatever powered this man forward, it did not acknowledge the absence of a functional heart as a reason to stop moving.
He raised the naginata one more time.
Gion watched this happen and said nothing for a moment.
"For your will alone," she said finally, very quietly. "That's worth acknowledging."
She raised Konpira.
Lightning moved into the blade steadily, with no haste, until the metal was saturated and the air immediately surrounding it distorted with heat and charge, and the edge could not quite be looked at directly.
"Cut him: Raikiri."
The blade fell.
Raikiri came from an old story: a swordsman who cut a bolt of lightning in two. The implication was that nothing in the path of that blade could claim the right to remain whole. Gion had named the technique with that understanding, and the technique had absorbed it completely.
Weevil's naginata separated at the point of contact. The cut continued through everything in its path and let the division complete itself cleanly, cauterized as it went by the lightning that burned away what it divided. A different kind of death would have been messier. This one simply ended.
The lightning in the blade dispersed into the air in its final discharge, flooding the sky briefly with white light, and for a moment the sea and the ship and everything between them was overexposed and indistinct.
Then the light faded. The clouds drifted back. The burning sections of the pirate ship hissed as they went under.
Gion stepped from the last solid plank and covered the distance back to the warship as lightning rather than as a person, resolidifying at the rail without apparent effort.
She straightened her coat. She checked the Konpira's scabbard lock. She was entirely matter-of-fact about it.
The cadets on the deck were very quiet.
Ace stood at the rail and looked at the settling water where the pirate ship had gone under. He was doing something that was not quite processing and not quite grieving for the comfortable idea of his own progress. He had been training seriously. He had been told, and had believed, and had tested himself against enough things to sustain that belief, that he was closing the distance toward something real.
He looked at what Gion had just done.
He looked at the distance between where he was and where that was.
The information was useful. It didn't sit easily.
He didn't say anything. There wasn't much to say that would be accurate.
The Den Den Mushi at Gion's hip began to ring.
She looked at it. Something shifted in her expression, subtle but readable to anyone who knew the difference between her performing composure and her simply being.
"It's Finn," she said.
Zephyr, leaning against the rail with his arms folded, made a short sound that might have been satisfaction. The old instructor who had watched her grow into everything she now was, from the beginning, didn't look particularly surprised. He'd have been surprised if she couldn't handle a Weevil.
"Answer it," he said. "I've been wondering when he'd get around to calling."
