English Translation
Zabuza, observing from the shadows of a nearby alley with Haku at his back, grit his teeth. The air in Northstar port had grown heavy, charged with a killing intent he knew all too well.
—Haku, listen —Zabuza whispered without taking his eyes off the newcomers—. Go to the ship with the supplies right now. Prepare the moorings and make sure everything is ready to set sail in a heartbeat. Don't stop for anything.
The boy nodded in silence, adjusting his porcelain mask before disappearing into the shadows of the warehouses. Zabuza was left alone. He knew he couldn't simply run; Fuguki had the nose of a bloodhound, and Raiga was fast enough to reach them before they cleared the pier.
Taking advantage of the sun sinking below the horizon, Zabuza invoked his technique. A thick, icy mist began to spout from nowhere, swallowing the port lights. He merged with the environment, moving like a specter toward Raiga's flank. His intent was simple: eliminate the fastest one to level the playing field. Zabuza launched the lunge with his common saber, aiming for the base of Raiga's skull from the invisibility of the fog.
The steel was centimeters from its target when the bandages of Fuguki's massive sword bristled violently. A groan escaped the weapon. Without even turning his body, the giant interposed the bandaged mass of his sword, blocking Zabuza's attack with a dry impact.
"—That stale, damp smell… —Fuguki Suikazan said, slowly turning his head. His pale face showed a smile full of sharpened teeth—. It could only be yours, Zabuza. Pity that the fog you love to use so much is now what gave you away."
Zabuza leapt back, materializing completely. The pain in his right shoulder, the burn from their previous encounter, throbbed with a renewed intensity that made his guard falter for a second.
—I see Bastion is still sending its dogs to hunt me down —Zabuza growled, readjusting the grip on his saber with his left hand.
Fuguki let out a hoarse laugh and swung the Samehada with terrifying ease. The very air seemed to be sucked in by the sword.
—You make a lot of noise for someone hiding in an alley —Fuguki mocked, while the Samehada vibrated—. The "Demon" of Shroud Island has been reduced to this: a wounded deserter taking care of a brat.
Fuguki narrowed his eyes, scanning the pier in search of something or someone.
—Tell me where the boy is, Zabuza. Is he still on the ship, or have you left him behind so he won't get in the way while I slit your throat?
Without waiting for an answer, he jerked his head toward the cargo dock.
—Raiga, stop staring at the clouds. The brat must be on that ship; go get him and make sure he doesn't escape. And don't forget to recover the Kubikiribocho.
Raiga nodded with a spark of malice and moved like a blue lightning bolt toward the dock where the ship was moored. Zabuza tried to intercept him, but Fuguki launched a horizontal slash that forced him to turn into mist to dodge it. As he did, Zabuza felt a violent tug; the Samehada "bit" the air, absorbing part of his energy. The swordsman materialized several meters away, coughing and feeling a sudden void in his lungs.
Haku had just secured the supplies when the smell of ozone hit him. Seeing Raiga approaching at superhuman speed, he extended both hands and, with an effort that made him grit his teeth behind the porcelain, manifested dozens of translucent crystal needles, launching them in a precise volley.
Raiga didn't even slow down. An aura of static began to crackle around him.
—Needles? Seriously? —Raiga mocked.
The crystal needles, upon entering the electric field, shattered into fine dust before touching the swordsman's skin. Haku launched a second volley, creating thicker blades, but Raiga simply moved his hand, sending a shockwave of hot air that deflected the projectiles like feathers.
—Nice uniform. Does Zabuza force you to wear that mask so he doesn't have to look at the face of the "tool" he's going to sacrifice? Because that's all you are in those clothes: a disposable shield.
Haku didn't answer, but his shoulders tensed with a slight tremor under Raiga's gaze. Raiga raised a finger, and a high-voltage spark struck right at the boy's feet, splintering the dock's wood and enveloping him in a pungent smell of ozone.
—Show me something worth breaking, brat —Raiga provoked, while the air around him began to glow with a lethal blue.
Haku backed away, feeling the heat of the static burning the air near his mask. Fear began to cloud his judgment, but in the middle of the chaos, the memory of the night before took hold with icy clarity.
--- Flashback
In the ship's cabin, under candlelight, Zabuza watched Haku with a mixture of curiosity and severity. The bounty poster lay on the floor, forgotten.
—A Devil Fruit, a Paramecia —Zabuza stated, ignoring the paper as if it were trash—. Ice, crystal, or something similar. In the end, it's just another tool. Make sure that crystal is lethal enough so we haven't wasted our time with this.
—I don't know how to control it... —the boy whispered, raising a trembling barrier of translucent crystal between them.
Zabuza let out an impatient snort and moved toward him. His imposing figure cast a long shadow over the boy, and for a moment, Haku thought Zabuza was going to strike him.
Haku closed his eyes tightly and cringed, seeking protection. As he backed away, his back hit the cold surface of the barrier he himself had created. But instead of hitting something solid, he felt a shiver run down his spine. The crystal didn't stop him; it absorbed him.
Zabuza stopped, bewildered.
A second later, Haku was expelled from a small crystal fragment on the floor at the other side of the cabin. He fell to his knees, panting and trembling, looking at his own hands as if they weren't his.
--- Present
—Game over, pet! —Raiga shouted, launching a massive discharge directly toward Haku's chest.
Haku didn't throw needles. He struck the dock floor, making four large crystal sheets sprout and surround him. When the lightning hit, the electricity dispersed uselessly across the insulating surface of the mirrors.
Raiga frowned at the silence behind the barriers. —A cage? This won't stop me...
Haku pressed his hand against it and vanished. He merged with the mirror in front of him and, an instant later, appeared in the reflection of the side mirror, moving at a speed that defied the eye.
—What the hell...? —Raiga spun on his heels, throwing random electric strikes, but only found his own reflection on the crystal surfaces.
In the distance, Zabuza saw the dome and knew it was his chance. Fuguki, distracted by the anomaly, lowered his guard for a fraction of a second. Despite the agonizing pain in his shoulder, Zabuza roared and used his mist form to propel himself forward, striking Fuguki and making him stumble back.
At that moment, the dock exploded into chaos.
—Marine Guard! Fire! —a shout was heard from the main entrance.
Fuguki stumbled back, his heavy boot screeching against the dock wood as he let out a growl of pure rage. His yellowish eyes locked onto the direction of the Marines; the flash of the muskets and the shout of authority from the soldiers were an interruption he had no intention of tolerating.
—Insignificant scum! —Fuguki roared, swinging the Samehada to disperse the gunpowder smoke with a gust of air pressure—. Raiga, move already!
Zabuza didn't wait for the giant to regain his balance. In a fluid motion, his body dissolved into a trail of mist, moving at a speed the soldiers couldn't track. He materialized right in front of the mirror dome that kept Raiga isolated.
—Haku! —Zabuza bellowed, striking the cold surface with his fist—. Forget it! To the ship, now! Release it!
Inside the reflection, Haku's silhouette tensed. Without a moment's hesitation, the boy slid out of the crystal, appearing on the ship's railing.
