Chapter 1: The Surprise Attack

It was just another normal day on board the Thousand Sunny. Luffy, Ussop and Chopper were playing a game of tag, their screams of joy filling the whole ship. Franky was making a piano for Brook in the aquarium, while Brook was by his side commenting on Franky's remarkable skills. Sanji was in the kitchen preparing for lunch, while Zoro was training in the Crow's Nest. Nami was tending to her mikans, while Robin was on the deck reading a book.

Suddenly, Nami felt a tap on the shoulder. She jumped in shock, turning around to find the captain behind her with a wide grin on his face. "Luffy! Don't scare me like that!" Nami yelled as she gave Luffy a huge punch on the head. Luffy fell to the ground comically, all the while mumbling "Sorry…Sorry…". " What's the matter
?" Nami asked Luffy. "Is it just me, or is the sky getting darker by the minute?" Luffy asked. Wow, even though our captain might be an idiot, he sure is observant, Nami thought. Nami nodded and addressed the crew. "Mina! A huge fog is approaching, and it will reduce our visibility by a lot. Stay alert!" "Haaaaaai Nami-swaaaaaan! I will protect you and Robin-chwan if anything happens!" Sanji cooed. Nami sweatdropped at Sanji's antics. "Nami can I have a mikan?" Luffy asked, revealing his true intentions for approaching Nami. "They are not ripe yet Luffy, maybe later." Nami explained. Luffy pouted childishly, and with a parting "Bleh!", he ran off to ask Sanji for some food.

Slowly, the Thousand Sunny became engulfed by the thick fog. They crew could barely see in front of them. The crew was now huddled in the dining area, with the exception of Zoro who was still training in the Crow's Nest. The crew was playing cards and they were enjoying themselves, laughing and shouting. Sanji was preparing for lunch in the kitchen. Suddenly, Luffy who was thinking of what card to play next, abruptly threw his cards down and ran for the exit of the dining area. "NANI?" The rest of card players exclaimed. Clank! Sanji had also dropped his pan and was dashing towards the exit, just behind Luffy. The rest of the crew, curious as to what was going on, followed the two.

Luffy had sensed the cannonballs flying towards them through his Kenbunshoku Haki, with Sanji realizing a split second later. Gomu Gomu No Fuusen! Luffy's body inflated as he jumped onto the path of the incoming cannonballs, deflecting them back. Sky Walk! Sanji has dashed up into the sky and kicked away the remaining cannonballs that had gotten past Luffy. The rest of the crew watched in awe as they could only see the cannonballs just as it was about to hit the ship due to the thick fog. Suddenly, they saw a shirtless Zoro jump out of the Crow's Nest, with two swords unsheathed. "What is he thinking, jumping out shirtless like that?" exclaimed Nami. Zoro somersaulted in mid air and parried a long distanced slash aimed at the ship which had just became visible. The monster trio landed on the deck. By now, everyone had heard the commotion and came out to the deck. "Shishishi! Looks like we are under attack," Luffy announced to the crew with a big grin on his face. "Suits me, my swords are itching for some blood," Zoro said with a demonic grin. "Can't they do it after I finish cooking?" complained an irritated Sanji.

Just then, a fleet of three Marine warships appeared beside the Sunny. A man jumped of the Marine ship and landed on the Thousand Sunny. The crews' eyes widened out of shock and a tinge of fear. They had not been expecting someone of his caliber to be out personally just to catch them on this surprise attack. Bad memories started flooding back to the crew, bad memories of their defeat back in Sabaody Archipelago. They were utterly and completely defeated by the man standing in front of them right now.

"KIZARU!" The Straw Hats exclaimed in unison.

"My…My… There is no need to look at me with such hatred you know. I came due to orders from higher ups." Kizaru drawled lazily. "I will not let what happened two years ago repeat itself," Luffy told him in a serious voice. His hat was now covering his eyes, symbolizing his seriousness. "My friends, my nakama, I will protect them all! That was what the past two years was for!" Luffy yelled. "Mina, go and take care of the remaining soldiers on the warships. I will take him on." The rest of the crew, even though worried for Luffy, decided to follow his orders. They jumped onto the warships and started counterattacking. Luffy, please be alright… Nami thought as she took out her Clima Tact.

Back on the Thousand Sunny

"I didn't really want to come after you again you know, but Sakazuki wanted me to. I hope you understand," Kizaru explained in his lazy drawl. Luffy tensed up at the mention of the man who killed his brother. Suddenly, Kizaru disappeared and reappeared beside Luffy at the speed of light, bringing a kick up to Luffy's forehead. Busoshoku Haki! Luffy clad his arm with Haki and blocked Kizaru's kick. Suddenly, Luffy's body erupted in steam. Sssssss… Kizaru was exchanging blows with Luffy in mid-air. Kizaru was flashing around at the speed of light, but Luffy, having gotten considerably stronger, was having little trouble catching up. They were relentlessly assaulting each other, exchanging blows which shook the seas around them. Suddenly, Kizaru turned into his logia form and emitted a bright light from his body. Damn it… Luffy thought. He was now unable to see due to the blinding light from Kizaru. Suddenly, he felt Kizaru reappear in front of him. Shit! Luffy knew he would not be able to escape this attack. Kizaru imbued his foot with Haki and kicked Luffy in the shin. Luffy flew backwards and hit the mast. When he finally regained his vision, he felt blood in his mouth and spit it out. However, Kizaru did not wait for Luffy to regain his senses fully before attacking. He turned into light and travelled to the top of the mast. Yasakani no Magatama! Kizaru crossed his hands in front of him and fired a deadly torrent of light bullets at a still dazed Luffy, The light bullets can tear through people easily, and there was no way Luffy could defend this attack.

Just as all seems over, a flash of green appeared. Santouryuu: Tatsumaki! A tornado was generated and it slashed and parried all the light bullets away. In the middle of the tornado stood Roronoa Zoro, with all three swords unsheathed. "Oi Luffy! If you don't get up you're gonna die to this bastard!" Luffy, upon hearing this, blinked a few times before springing up to his feet. "YOSH! I'm back and roaring to go!" Luffy declared, "Let's take him on together!"

Kizaru, on the other hand, sighed. Another enemy to deal with… this is not going to be easy. "Ama no Murakumo!" He screamed. Kizaru formed a long, very sharp sword out of light and solidified it. "Didn't really want to use my sword here…but it couldn't be helped." Without warning, Zoro leaped up and slashed out at Kizaru. Kizaru managed to parry it easily, but Zoro followed up with a series of slashes. Clink! The sound of swords clashing echoed throughout the seas. Zoro's impressive swordsmanship skills were keeping up with Kizaru, an admiral. Zoro knew that if they continued sparring, it could go on for days. Time to show him what I'm really made of. In a flash, Zoro jumped up, gaining some leverage on Kizaru. Busoshoku Haki! A demonic aura started to appear on Zoro's blades. Santoryuu: Ul-Tora Gari! Zoro swung his swords in a forward descending slash, with an aura of a tiger following. This attack… It's pretty strong! Kizaru thought. He had to exert himself in order to parry the blow.

Gomu Gomu no: Jet Bazooka! Kizaru felt an attack coming, but he was sent flying before he even had a chance to dodge. Luffy had jumped up in his Gear Second form and had sent a devastating bazooka towards Kizaru as he as busy fending off Zoro's attacks. Kizaru flew NOT faster than light but still fast all the same. He hit the ground headfirst, and his forehead started to bleed. He wiped some blood from his mouth and said," My, my. You punks should really know where you stand." He turned into light and reappeared at the top of the mast again. "ZORO! CLOSE YOUR EYES!" Zoro, trusting his captain completely, immediately shut his eyes. Kizaru emitted a blinding light again, but this time Zoro and Luffy had their eyes shut. It had no effect. Yasakani no Magatama! Kizaru sent out a torrent of light bullets again. Kenbunshoku Haki! Luffy and Zoro could now sense the presence of Kizaru's attack. They both jumped up, and flew towards the top of the mast at great speed, twisting and turning their bodies to dodge each and everyone of Kizaru's light bullets. Busoshoku Haki! Luffy clad his fists in Haki while Zoro clad his swords. "Gomu Gomu no: Jet Gatling Gun!" Luffy screamed as he launched his attack towards Kizaru. "Santoryuu Ogi: Ichidai Sanzen Daisen Sekai!" Zoro yelled. Luffy delivered tons of punches to Kizaru, who had no time to dodge as he was launching his attacks. Meanwhile, Zoro delivered massive slashes to him one after another relentlessly, Kizaru took these attacks head-on, and he fell from the mast. Kizaru was now reduced to a bloodied pulp. He had swollen and sore spots everywhere, while every single part of his body was covered in slashes, courtesy of Zoro. Needless to say, Kizaru was now bleeding profusely. Luffy and Zoro had beaten an admiral.

"STOP!" A voice yelled from the marine ship. "What?" Luffy and Zoro said in unison as they looked up. Luffy's eyes immediately grew wider in anger as he saw the scene before him. In front of him stood a Marine vice-admiral, holding Nami with one arm, while pointing a katana at her throat with the other. "I am Vice-Admiral Nuro! If you don't want her to die, return Admiral Kizaru now! We have the rest of your crew too, so release Admiral Kizaru at once. And you will allow yourself to be exchanged for her, Mugiwara Luffy!" THIS BASTARD! IF I GET MY HANDS ON HIM I'LL TAKE HIM OUT MYSELF! Luffy thought in anger. Luffy unleashed a wave of Haoshoku Haki at Nuro. The only effect it had was making Nuro laugh. "HAHAHAHA! Your Haki is not strong enough to take me down yet! Make another attack and you will bid your goodbyes to your fellow crewmates! Just come already, you can't win this battle." Just then, tears started streaming down Nami's face. "Gomen… Luffy. He can turn invisible and caught us off guard. Please.. don't-" "Say no more, Nami. I'll go," Luffy said in a serious tone. He held both arms out to be cuffed.

The crew was returned, and Luffy was in captivity. Being dirty as usual, Nuro took Nami too. He threw them into a small cell on the Marine ship and sailed away, leaving the Thousand Sunny in the distance.
