The Assassins Attack! The Great Battle On Ice Begins! is the 329th episode of the popular anime series One Piece's sixth season. The episode begins with Robin warning the Straw Hats about the arrival of the enemy assassins, Kaku and Kalifa. The duo has been sent by CP9 to eliminate the Straw Hats and retrieve the blueprints of Pluton.

As the Straw Hats prepare for the upcoming battle, a group of giant sea monsters attack the Thousand Sunny, forcing the crew to come up with a plan to evade the creatures. Meanwhile, Kaku and Kalifa make their way to the island where the Straw Hats are located. The duo has been tasked with retrieving the blueprints of Pluton, a powerful weapon capable of destroying entire islands.

As they approach the island, Kaku and Kalifa are confronted by Sanji and Zoro, who have been tasked with protecting the crew. The two assassins put up a tough fight, but Sanji and Zoro manage to hold their own against the powerful opponents.

Back on the Thousand Sunny, the rest of the crew manages to evade the sea monsters and continue their journey towards their destination. However, they soon realize that they are being followed by a group of enemy ships. Franky decides to take matters into his own hands and takes on the enemy ships head-on using his powerful weapons.

With the enemy ships taken care of, the crew makes it to their destination, where they are greeted by a frozen wasteland. As they make their way across the frozen terrain, they are attacked by a group of enemy soldiers, who have been sent to stop them from obtaining the blueprints of Pluton.

The Straw Hats manage to defeat the enemy soldiers, but their victory is short-lived as Kaku and Kalifa arrive on the scene. A fierce battle ensues, with both sides giving it their all. Kaku and Kalifa prove to be extremely powerful opponents, but the Straw Hats refuse to give up without a fight.

As the battle heats up, the frozen wasteland begins to thaw, revealing a massive body of water. The two sides continue to fight, but the water begins to freeze over, creating an icy battlefield. The battle on ice begins, with both sides slipping and sliding across the frozen surface.

As the battle rages on, the Straw Hats begin to gain the upper hand. However, just as it seems like victory is within their grasp, Kaku unleashes a powerful attack, sending the crew flying across the ice.

Despite the setback, the Straw Hats refuse to give up. They band together and come up with a plan to defeat their powerful opponents. With their teamwork and determination, they manage to turn the tide of the battle and emerge victorious.

The episode ends with the Straw Hats regrouping and preparing to continue their journey. However, they know that more dangerous enemies still lie ahead, and they must stay vigilant if they hope to survive their journey.
