The New World, The Blue Sea.
The sun slowly set on the western horizon, painting the blue sky with a tinge of orange. The three-masted ship of the Cannonball Pirates did not give up after their first failed shot. They continued to launch a barrage of cannon attacks one by one. However, every fast-moving projectile was easily stopped by Sandersonia, who was suspended in mid-air using her signature technique, Rankyaku.
This stalemate continued for quite a while. Finally, Boa Hancock emerged from the Perfume Colubrid's cabin with Marigold. Wearing a purple cheongsam that hugged her proud figure, she gave a lazy yawn. "Ha! What exactly is going on that I can't even get my afternoon nap?" her voice sounded cold and rather arrogant.
Hearing the empress's question, Sandersonia, who was still in the air using Moonwalk, immediately landed lightly on the deck. "My sister, ten kilometers from here, there is a pirate ship that keeps firing at us," she explained.
An expression of anger flashed across Hancock's face. She waved at the orange-haired Marigold behind her. "Marigold, sink that ship for me immediately!"
"Yes, Sister!" Marigold replied.
After giving her order, Hancock went back into the cabin. As she left, she barely managed to keep from stumbling as she overheard the strange whispers of her female crew.
"Wow! Miss Hancock looks so cute when she's angry!" "Yeah! I really want Miss Hancock to scold me harshly!"
As time went on, Hancock's charm had only increased. She often felt that her own crew and citizens were becoming more and more strange. Therefore, she had to pretend to be aloof to reject their nonsensical admiration.
After receiving Hancock's order, Marigold walked leisurely toward the back deck of the Perfume Colubrid. Her eyes flashed red. With the help of Observation Haki reinforced by her power, she enveloped the area for about thirty kilometers. Her sight and hearing stretched instantly, locking onto the position of the enemy ship in the distance.
After estimating the enemy ship's trajectory, Marigold touched the leather pouch tied to her thigh, then took out a silver alloy coin the size of a hat. On one side of the coin was engraved a "Z" lightning pattern, and on the other, the Kuja Pirates' skull pattern.
Railgun!
Marigold poured Armament Haki into the coin, turning it pitch black. She then threw it into the air. As the coin fell, she had already predicted its attack trajectory through her sight and hearing. A strong blue thunder light exploded from her body. Marigold created an accelerated magnetic field in an instant, using a super-strong current as the force to fire the alloy coin at a speed exceeding three times the speed of sound.
In the process, the alloy coin continued to accelerate thanks to the magnetic field and the super-strong electric current. Its motion trajectory created a streak of light in the air, and the strong gust of wind it carried formed an arc-shaped corridor in the sea.
Captain David, who was sitting at the long-barreled cannon's console, saw a blue-white ball of light with a slight orange-red tinge coming from the Perfume Colubrid. He was still wondering what it was, until the next second...
BOOM!
In the blue-white thunder, the lightning ball that enveloped the Haki-coated coin heated it to a glowing red. The coin pierced the entire ship from the bow, blowing it to pieces and tearing the hull apart. A raging fire burned the remains of the shattered ship.
At the stern of the Perfume Colubrid, after Marigold confirmed that the enemy ship had completely sunk into the sea through her sight and smell, she turned and went back to the cabin. The Railgun was a move that Sephiroth had suggested she develop with her Devil Fruit ability.
If only an ordinary coin were used, even when wrapped in Armament Haki, the coin could only be fired about 500 meters before it would burn out from friction. However, with the special alloy made by Jin, that problem was solved. The effective range of this Railgun depended on the scope of Marigold's Observation Haki. In other words, Marigold could use this move to perform an over-the-horizon attack of thirty kilometers.
However, this Railgun was only suitable for destructive attacks on ships at sea. Its incredible destructive power and speed could not be stopped by conventional means. Even so, using this move against enemies who had Observation Haki or were quick to react was basically the same as attacking their whole body. People might not be able to stop it, but they could avoid it. After all, an electromagnetic weapon required three to five seconds of preparation, and that amount of time was enough for strong people to dodge.
Even so, compared to other thunder attacks, the energy consumption of the Railgun was much smaller, making Marigold very satisfied with this technique.
Sabaody Archipelago, Island 42.
The Perfume Colubrid slowly docked on the beach, and the three Boa sisters with masks on their faces walked out of the ship. Because of the treasure piles that filled every corner of the ship, Hancock ordered all the crew to stay on board, awaiting her orders. If she wanted to sell these billions of Berry's worth of treasure in secret, she had to go to Sephiroth. With the large scale of the Umbrella Corporation, it was very easy for them to directly process this treasure.
After buying some groceries, the three Boa sisters carried their shopping in a soap bubble and walked toward the villa on Island 41. When Hancock opened the door with her key, she saw Perona lying on the table, working on a math problem. The pink-haired girl frowned, holding a pencil in her hand, with a look of hesitation. From time to time, there was a "Hmm! Hmm!" sound as she thought hard before finally writing down the answer for one of the function problems.
PLAK!
Seeing the scene, Sephiroth, who was standing behind Perona, immediately raised his right hand and patted the girl's butt gently. "That's wrong! Think again, how do you solve this problem."
"Oh~!" Wearing seven-centimeter-high heels and with her slender waist twisting, Hancock walked to the side of the two of them. "What are you doing? Show me," she asked curiously.
Hearing that, Sephiroth immediately wrote down a math problem and handed it to the tall, dark-skinned girl.
(X2+YX2−1)2−X2Y2=1
After grabbing the problem, Hancock started to move her hands, preparing to solve it.
"Hmm! Hmm!..." She opened her red lips and bit her pencil, but her mind was blank. The difficulty of the problem was too great for her to comprehend.
