SIDE STORY

Duel between The World's Greatest Swordmen

PART ONE

Dressrosa, Corrida Colosseum

"Ladies and Gentlemen! Today is a very special occasion! We will witness a duel between Dracule Mihawk and Roronoa Zoro! The winner of this duel is the World's Greatest Swordman! Will Dracule Mihawk keeps his title or will Roronoa Zoro steals it from the current title holder? I am Gatz and I will be your announcer for the next three hours!" Gatz is still in the middle of the stage, between Zoro and Mihawk. "Will you explain why you two choose this place for your duel?" Gatz asks to them.

"..." Zoro and Mihawk are silent, unwilling to reveal their reason. Their duel happens at a Colosseum is so out of place for them.

"Well, if you don't want to tell us is okay. I will announce the rule. This duel is without time limit, so you can continue to battle as long as you are fit to do so. Because of that, announcers and medical team are rotated, with three hours for each person. The only weapon allow is sword. You can you as many sword as you want. The duel is finish when one of you dead or too exhausted to continue the duel or if the medical team decide to interfere."

Gatz walks to podium and says, "Before the duel started, I have to continue to explain today's different to our usual battle. There are three announcers and three doctors. For the other announcers, we have Princess Viola and Princess Rebecca!"

The crowd yells and clap their hands at the sight of Dressrosa's beautiful princesses.

Gatz finally stands at podium and says, "As for today's Colosseum Canteen, our usual staffs are off the duty and watching this duel. We are having Chefs of Floating Restaurant, Baratie, as our staffs today!" Baratie is world famous now, many people goes to East Blue in order to visit this restaurant. The crowd is murmuring in appreciation and anticipation upon hearing this news.

"Today's medical team, who are also the referees for this battle, consist of famous doctors. They are Doctor Chopper, Doctor Law and Doctor Hogback."

Spectators are silent upon hearing this news. 'Who is the heck that can manage to get them going here?! The tanuki doctor is Zoro's teammate, no surprise there. Law was in alliance with Straw Hats, while seeing him is shocking, it's understandable. But manage to brought Hogback to light after years of no news about him?!'

Gatz try to lighten the mood. "Let's clap our hands to give our referees an encouragement!" The spectators snap out of their thoughts and claps enthusiastically.

A ghost is flying to Gatz side and whisper him something. Some of the crowd have seen Perona's ghosts so they are not shock. The others have heard news about the infamous Ghost Princess but still shocked that they almost bulge their eyes out. They then see Ghost Princess sitting beside a glasses woman. 'Ah. So she is the perpetrator...'

"To make this duel more interesting, there is a bet for the result of the duel! If Mihawk wins, Ghost Princess will work for the Marines for a month! If Zoro wins, he will have a two-weeks long date with Rear Admiral Tashigi!" Gatz delivers the news and the crowd goes wild.

Gatz shakes his head and thinks, 'No wonder there are so many Marines in this Colosseum and glaring at Zoro...'

Zoro himself is about to explode and yells, "PERONAAAAAAA!"

Mihawk is amused and says to Zoro, "You still got ways to go if this easily influenced you."

Zoro turns to Law and protests to him. "Can't you stop her? How did she manage to goad Con-Tashigi to agree?!"

Law sighs and says, "You know how stubborn Perona is. Smoker, Fujitora, and Garp managed to make Tashigi agree to the bet."

"Bully her to it, you means." Zoro feels sorry for The Con Woman, those Marines high-ups are sure shrewd.

Gatz clears his throat. "I have finish explaining the rule. Are you ready?" He asks at the swordmen. They nods and takes position.

"On your mark, Law-san." Gatz give the authority to Law.

Law grabs a pistol and directs pistol's mouth to the sky. "The duel begins when I shoot this pistol. In three. Two. One."

*DOR*

Their swords clash in a flash after the pistol is shot. The duel begins.

How did Perona manage to make them agree in a duel in Colosseum?

Let's rewind to few days before...

Kuragaina Island, Mihawk's Castle

The Straw Hats are taking a break in searching for One Piece. They have enter their 6th year in New World, but Raftel is still not found yet. They have fought along the way. Zoro thinks that time to challenge Mihawk again have come. So he asked Mihawk and they decided to meet at Kuragaina. They want to take last supper first, along with sake for Zoro and wine for Mihawk, before having their death match.

They are just about to sit when ghosts floating around and shouts, "NO DUEL YET! You stubborn, brooding and overflowing with testosterone swordmen!"

Zoro is first to says, "Perona, how could you know about the duel?"

Perona opens the door and glares at them. "Robin and Nami called me. They thought I need to know. One or both of you might died in the duel, after all."

Mihawk opens his mouth. "Meddling, aren't they?"

Law entered the room after Perona. "Our ship traveled so fast in order to reach this island in time. And she had dark mood all along the journey."

Perona takes a breath and drops the bomb to them. "I'm pregnant."

Both of Zoro and Mihawk are currently filling their glasses with their alcoholic drinks, without noticing that their glasses are already full. Law clears his throat and they put their bottles down.

Zoro says this gruffly, "Congratulations then."

Mihawk pierces his gaze at Law, says, "I assume that Law is the father."

'What in-laws that I have.' Law rolled his eyes. "Of course I am, I'm her husband after all."

"I failed to see how your pregnancy and our duel relate." Mihawk tells Perona coldly.

"Because I want my child to meet both of you. It can't be done if one or both of you die." Perona is used with Mihawk cold words.

Zoro asks Perona, "You don't want us to stop our duel and wait until the child is born, right?"

Perona plead to them with her puppy eyes. "No, I want you guys to have your match with doctors supervising you. I know that both of you have a great pride as swordmen and want a fight to death, but win or lose, can you guys keep on living to meet my child? And see he or she grows? Please?"

Zoro and Mihawk sighed. They have soft spot for Perona, which they will never confess to anybody, ever.

"I don't mind having doctors to oversee our match." Zoro is defeated.

"Why you say doctors instead of doctor?" Mihawk is also defeated.

Perona smiles. "Because knowing you two, the duel will be days instead of hours. One doctor is not enough."

Law was on his Baby Den Den Mushi during the pleading. He then says. "Bepo told me that he has been informed. Preparation complete. We can go ahead using our submarine."

"Let's travel after supper. There are still enough food for two more. Why don't you join us?" Mihawk invites Perona and Law to eat.

"I'll inform Sachi that we are eating here." Perona tells Law. Law nods. Perona's ghost informs Sachi back at te submarine.

"How far are you, Perona?" Zoro asks Perona and they begin to eat while discuss some things, mainly Perona's pregnancy.

Later that night

"Perona, thank you for persuading them to agree to that." Robin, Nami, and Perona are currently on a Den Den Mushi conference.

Perona is snuggling comfortably to Bepo's body. They have been best friends for years. Bepo only allowed Law and Perona to snuggle to him.

"Your welcome. I still don't see why you guys leave the job to me." Perona says to them.

"Zoro won't listen to me." Nami is annoyed by the fact that she always have a hard time to make Zoro do her biding.

"Your pulling him to debts scarred him for life. He calls you witch, you know. What about you, Robin?" Perona smiles. 'Zoro have a long memory, that's for sure.'

"I can twist him to agree, but he will be crossed at me for a long time if I do that." Robin says nonchalantly.

Perona grimaces at the literal meaning of Robin's plan. "Okay, I see your points. Are you sure about having the Colosseum as the place for the match? They will be crossed at me for a long time."

Robin says, "They won't. Not for long. They adore you, not to mention they will be waiting to meet the baby."

Nami, the planner, says, "It can't be helped to have Colosseum as the place. We need big building for all the people who is coming. Our crews decide to meet with family and friends there instead of going home. We need a lot of money for traveling back and forth. Using this duel as a money making is a brilliant idea if I say so myself. So is convincing Baratie to cook there."

Perona sighs. "Just be careful with brooding swordmen." Law entered the room. He kisses Perona's cheek and says, "Bed time for you, Princess."

Perona blushes slightly and say goodbye to her friends. Bepo blushes heavily and go out the room quickly. She lets Law take her to bed. Law is overprotective these days, despite the fact that he is a doctor and he knows that Perona's health in great condition.

Dressrosa, one day before the duel

When the submarine resurfaced and boarded at Dressrosa's harbor with Dressrosa's citizens waving at them, Zoro and Mihawk glared at Perona.

Zoro points at Perona accusingly. "You are planning this with Nami and Robin."

Mihawk scolds Perona. "They have bad influences at you, Perona."

"You are not having enough mental fortitude if the possibility of having lots of people witnessing your match shake you." Perona was not watching Mihawk trained Zoro for nothing.

Zoro's and Mihawk's bodies stiff at the challenge. They answers. "No trouble with that." "Bring it on!"

'Mission complete. I have confirmed the bet with Tashigi last night.' "The duel is tomorrow at Corrida Colosseum. Tell me when you want to start later." Perona then walks to Viola and Rebecca.

Before the banquet at Dressrosa's Castle, one day before the duel

Zoro asks Perona to meet him at the balcony.

"Mihawk and I decide to start the match at 9 o'clock in the morning." Zoro is still annoyed at Perona.

Perona pities Zoro and gives him an olive branch. "Okay. Zoro, if I were you, I will fight my share on the money for the tickets tomorrow instead of brooding. When again you can strike back at Nami? Not to mention the fact if you become World's Greatest Swordman but still penniless is not cool."

Zoro ponders at the advice and decide to give it a try. He then ruffles Perona's hairs affectionately. "Great idea, Perona." He then braves himself in order to bargain with Nami and walk away from balcony.

Law use his 'Room' to travel across the hall and enter the balcony. He know that Zoro and Mihawk are like family to Perona, but he can't help but feeling jealous. "You have too many male friends."

Perona sees uncertainty at his eyes and hugs him. "I can't help it. Most of the pirates are male. So is the Marines."

Law hugs Perona back. 'It's annoying how quick women to mature compare to men. She was so childish years ago.'

Perona tells Law. "I don't mind that you're jealous. I will be jealous too if I see you with women. It's a good thing that you don't have many female friends." She kisses his lips.

Law kisses her back, passionately. "Let's go to our room." He caresses her neck softly.

Perona moans. "But Luffy will finish banquet's food in a minute."

Law whispers to Perona's ear. "We will be quick. The banquet won't start in another ten minutes."

Perona takes Law's hat. "Let's do it, then."

They are in their room in a flash. Ope Ope no Mi sure is handy.

Corrida Colosseum, one hour before the duel

Chopper changes to his guard point when he see Hogback. "What are you doing here?! He can't be on medical team, Perona?!"

Hogback says, "You worry too much, Chopper-kun."

Perona tries to sooth Chopper's nerve. "Don't worry about him. Hogback, Absalom, and Moria-sama promise that they will be on their best behavior. If it's not enough for you, I will be watching him closely during his turn."

Law adds, "Zoro and Mihawk won't let him do something stupid to them and he know better than to cross Perona."

Chopper changes to his small form and tells Hogback stiffly. "I'm watching you."

Hogback rolls his eyes.

How is the fluff degree? Is it enough for you?

Law is sweet and caring with a little twisted humor and tough persona mask. Few years after Dressrosa Arc, I think he will have some of his personality before his mental breakdown back but not all.

The match is hard to write. Can you give me some ideas?

Please review.
