One Piece and Tenchi Muyo GXP Crossover

By: Sayaalv

(A/N: I own nothing and what if Seina was really Luffy from One Piece complete with his gum gum powers? What if during his meeting with the King and Queens of Jurai a live video of Vivi about to be executed by the Marines played and forced him to reveal himself to those that thought him dead and/or missing? AU OOC and Alive Ace and Whitebeard.)

"Yes Father." Lady Airi began the meeting at King Azusa of Jurai's request. Just as Lady Airi opened her mouth to speak a screen popped up in the middle of the table, triangulated so that everyone could see it clearly. On the screen was a man wearing a bird hat standing over a blue haired woman kneeling on an execution platform.

"Vivi!" Seina Yamada, known to others as Straw Hat Luffy, exclaimed shocked at seeing the woman on the execution platform. The two queens and the king shot him curious looks, he knew the woman on the execution platform?

"This woman, princess Vivi of the kingdom of Alabasta, is going to be executed for helping pirates wanted by the World Government and she has been convicted of being a pirate herself. Namely, she is a member of the Straw Hat Pirates!" The man, whom Seina recognized as Sengoku, exclaimed into the snail phone so that everyone could hear him.

"Anything to add your highness?" Sengoku asked sneering the word 'highness' sarcastically down at the woman.

"Yeah you left out the part where I offer refuge to any pirate that does not kill, rape, or plunder for the hell of it." Vivi added with a grin causing the queens of Jurai's eyebrows to shoot upwards. Not only was this princess admitting to her 'crimes' but adding to it!

"Adding to your list of felonies, princess?" Sengoku sneered down at her in surprise, he wasn't expecting this.

"Why not? You're going to execute me anyways, mine as well make sure you get all your facts straight first." Vivi said with a shrug, causing Seina to snicker at the look on several of the marines faces at this.

"Mind moving my bracelet though? If you're going to kill me for being a Straw Hat Pirate you might as well let me show the mark that shows that I'm their nakama." Vivi asked causing Sengoku to debate for a second before nodding, he would at least allow her that. The black bracelet was moved up her arm to show a black 'X' mark on her arm.

"This woman is strange for a princess. She seems unafraid of dying as a criminal." Queen Funaho remarked softly and causing Seina to grin widely.

"She's not really a criminal she was just helping her nakama." Seina corrected before looking around when he heard humming. Mitoto was nearby cleaning the walls and causing the assembled group to wonder when and how she had gotten over there without them seeing her.

"And besides? Who said she was going to die?" Seina asked rhetorically with a mysterious smile on his face as he kept looking in between Mitoto and the screen with a calculating look on his face.

"What do you mean?" Queen Misaki questioned curiously, wondering how the boy seemed to know this 'criminal'.

"The Straw Hat Pirates are many things but if there is one thing none of them would ever do, it's abandon their nakama. Looks like Nami just showed up at the least." Seina said grinning when he saw the clouds go from clear to dark in less than a minute over the video feed. The two queens, one king, and one chairwoman watched as the clouds began to rain and lightning fell upon several unlucky marines as the camera panned out to show all of Marineford.

"Marineford again? Man are they predictable." Seina said shaking his head in disbelief when he saw the large marine base on the screen.

"Thunder Tempo!" An unknown woman's voice said as more lightning fell from the sky and electrocuted quite a few marines.

"It's Cat Burglar Nami!" One marine shouted before his neck was broken with a hand that seemed to be growing out of his back as a dark haired rather beautiful looking woman appeared beside the orange haired Nami.

"Nami and Robin. Two of the most dangerous women I have ever met…especially when they work together." Seina said grinning as he watched his crew members rush to save their friend.

"D-Devil's Child." One marine said running at the sight of Robin who merely smiled as a black clad figure appeared out of seemingly nowhere and kicked the man a good hundred yards away.

"That's no name for a lady…especially a lady as beautiful as Robin-swan." The black clad blond man yelled at the marine he had kicked before his eyes turned to hearts as he looked over at Robin. Quite a few marines paled and tried to run for it when several ship docked at the base and their inhabitants jumped down.

"Fleet Admiral Sengoku! It's the Straw Hats and their allies! The only one not here is the Captain of the Straw Hats!" One marine shouted up at Sengoku who merely nodded in understanding at this as more and more ships appeared around the Marine Base.

"Strange. The only ally the Straw Hats have that I remember are the Heart Pirates… a lot must have happened in such a little amount of time." Seina said as Mitoto came over and watched the screen curiously.

"Go ahead, give up, and give Vivi back! You marine bastards didn't win when you tried to kill Ace and you won't win now!" Nami shouted up at the marines, causing Sengoku to smirk down at her smugly.

"You may have saved Fire Fist Ace, that is true, but this time we are prepared for you. Especially since your captain is missing in action." Sengoku said as two men with swords walked up the execution platform and got into position, causing Seina's eyes to widen.

"Mitoto, can you get me to that place before they can chop of Vivi's head? The other's won't make it to the platform in time and Robin can only use her 'bloom' powers to a certain range." Seina asked turning to look at Mitoto hopefully and causing the black skinned blond woman to nod without her usual smile on her face, even she could sense the seriousness in Seina's voice.

"If you leave now you may never get the chance to have this meeting again boy." Azusa spoke up glaring at Seina for thinking he could leave without being dismissed.

"With all due respect your majesty I don't care. My nakama is in danger. Whenever you're ready Mitoto." Seina said causing the blond woman to nod and grab him by his jacket sleeve, focusing her dimension travel ability to get them both to Marine Ford in time. Funaho and Airi had put a few pieces together at his words and stared at him in shock as he and Mitoto vanished from the ship.

"Thanks Mitoto. You'd better go back before you get hurt in the battle." Seina said thankfully to the blond woman who merely smiled and seemed to ignore him as she began to mop up the floor of the battlefield.

"I'll be fine but you better go save your friend Seina-kun." Mitoto said smiling at him and causing him to nod as he turned towards the execution platform, smirking since no one seemed to notice him and Mitoto suddenly arriving as he took a deep breath.

"STOP!" Seina screamed at the top of his voice, unleashing his Haki as he did so. The mere pressure of his Haki had caused many Marines to pass out as both sides were frozen by the immense pressure, luckily the two men holding the swords that were an inch away from Vivi's neck were two of the thousands knocked out.

"This seems familiar." An old woman wearing a marine jacket like a cape said looking around to see who released that much pure Haki.

"The Haki of Kings again?" One of the pirates that had been there when Luffy had went to save Ace asked looking around as well. At what seemed like the exact same moment every single eye turned towards Seina who had begun to walk forward once all the marines were out of the way.

"He knocked out that many people with just a shout and some foreign power?" King Azusa asked staring at the screens in shock, as was his two wives and his daughter-in-law.

"This is surprising." A man wearing a yellow pinstripe suit said slowly as he looked down at Seina from atop a battlement.

"You're kidding right?" A man with a sleep mask on his head asked looking shocked at the sight of Seina.

"That brat." A man wearing a red suit underneath his coat said glaring down at Seina hatefully as he began to run towards the platform with the other pirates cheering and running behind him.

"He's using it consciously now which means he must be more powerful than before." The pinstripe suited man said slowly again.

"We may have failed last time but this time we'll make sure he dies!" One of the men in a purple suit yelled, causing the other marines to cheer and rush towards Seina with their swords at the ready.

"Seina!" Amane and Kiriko exclaim in worry for their long time crush as they stared at the screen in front of them with Ryoko Balta, Fuku, Neju, and Mikami right beside them.

"Now that he's back we will make sure he does not survive! All marines focus your attention on killing the son of the revolutionary Dragon, Straw Hat Luffy!" Sengoku yelled pointing at Seina and causing the black haired teen to grin viciously at them all while an old man that resembled a bull dog was sitting in a large chair and staring at Seina.
