The heart pirates little treasure

A mistake.

Taiga's POV!
I tense, thinking of a solution as Sanji gets caught in Doffy's trap. Without warning, Law tosses a stump and switches us with it, then switching Doffy with us, leaving Doffy to attack nothing.
"Sorry, I made a mistake! Let's get on the ship!", Law says, letting us drop onto the ship with Caesar as our cushion.
"Traffy-San! Taiga-Chan!", Brook says as we land near them.
"Sanji!", Chopper says as the guy himself flinches in pain, I on the other hand fish inside my bag for a piece of candy and water bottle then hand them to Law.
"Thanks Taiga.", he says, taking the stuff from me and petting my head softly.
"Damn! I'm on the ship again!", Caesar shouts, making a huge fuss about something small.
"Shut it stupid!", I shout angrily, jumping on his stomach in anger.
"Hmph! I really don't like you! Now! How's the kitchen? I need snacks! Food!", I shout, jumping off of his stomach and wandering into the kitchen. I freeze, sensing the familiar energy of Doffy heading our way.
"Law! Doffy! He's heading back!", I exclaim, pointing up towards the guy himself as I pull out one of my bombs.
"Keep watch out Taiga, he's bound to be aiming for us again. Anyways, Black foot-ya, hows the plan to destroy the factory going?", Law says, turning to Sanji.
"We found out where it is but Franky said it's going to be harder than we thought.", Sanji answers as I put the bomb back in the pocket in my hat and pull out my sword instead.
"So we need more time.", Law whispers, holding out his hand to me as I step up next to him.
"Fine, but can I at least do a squeeze?", I ask, pulling out Caesar's heart from my own cavity as Law hands me mine. He nods silently, a small smirk on his face as Caesar notices that I had his heart as I put mine back in me.
"Heehee! This! Is for calling me a brat!", I exclaim, giving Caesar's heart a huge squeeze that has him rolling in pain as I laugh in glee.
"Maybe you should hang out with Raccoon-ya more and not me...", Law says, scratching his neck at the display.
"Hm? Why's that?", I ask, handing the heart over to him.
"Never mind, I'm actually proud now as your older brother that I've rubbed off on you.", he says happily.
"Yay! I'm glad you're proud!", I exclaim happily, jumping up happily as I feel more power coursing through my veins at having my heart back.
"Everyone! I want you to take him and head for Zou, Taiga is to stay with me however, she's a great asset to my plan and-", He explain, only for Sanji to cut him off.
"Because she's your sister?", Sanji says, smirking at me kindly.
"Yeah! You guys have that vivre card right? That'll lead you straight to Zou! Just follow it and you'll be there!", I explain happily, pulling out a piece of energy candy I helped make and tossing it in my mouth.
"Head for the island? What about Luffy-San and the others?", Brook asks.
"The only thing left on here is to destroy the factory, which I'm sure can be handled easily. We can catch up later.", Law says, patting my hat precariously.
"No! We'll wait! We can't set sail without our captain! We're the Strawhats!", Nami shouts, catching me off guard slightly as a quake hits the ship.
"There's no time! Someone is sending a navy ship at us! We need you guys to leave! Plus! Doffy is right across the way! If you want you can leave but just keep Caesar here!", I shout, pulling out Aoioni from my waist as the navy ship fires at us. I turn towards the meteorites flying our direction and jump towards them, missing whatever was being said and slashing at the two large projectiles.
"Flash style: black crescent! Sea slash!", I shout, slashing the two meteors in half horizontally then using the sea to catch the bottom parts and letting the two top halves fly above the ship and letting them hit the navy ship while landing safely on Sunny again. Everyone stares at me in shock while Law had a look of pride as I turn towards the navy ship, it hadn't let up at all in its assault despite the damage to the hull.
"May I Law-onii?", I ask, smirking happily as I tuck away Shirokuro but keep out Aoioni.
"I think they're heading somewhere else, Doflamingo is coming though.", Law says, making pull out Shirokuro again alongside a smoke bomb with added 'flash'.
"He's here, and he brought his whip again.", I catch, aiming Aoioni towards the incoming opponent who throws a flaming whip at us and catches Law's sword.
"Nami-ya! Listen! You have to sail where there are no clouds! Taiga, catch the guy off guard! Encapsulate him!", Law says, looking back to Nami and the others.
"What?! Why?!", Nami shouts, turning towards us.
"Doffy ate the string-string fruit, he's a devil fruit eater like me and Law! Using those strings he attaches them to clouds and flies using those! No clouds means no way for him to follow you!", I explain, calling Aoioni's special ability and focusing heavily on pulling water up to Doffy.
"Strings? I see!", Sanji says, still holding his shoulder in pain.
"Just go now!", Law shouts, tossing Doffy's whip away as I pull up enough water from the sea to cover Doffy.
"Blue shield!", I shout, bringing the water up to cover Doffy quickly as they pull a coup de burst. We blast off quickly, the defense I had pulled up disappearing slow enough that he couldn't track us but I take a small break as Law picks me up by the scruff and takes the weird neon lady with us on the bridge. I end up sitting on the weird lady's side, keeping Aoioni by her neck as me and Law waited for Doffy to come and pick her up, based on her shouts she must have been close to Doffy.
"He's coming...", I whisper, hearing his footsteps and feeling his angry aura coming near.
"What's the point in letting half of the Strawhats get away? The other half is in Dressrosa. If I take them as hostage, they'll come back right away to return Caesar to me.", Doffy says, as if we didn't think about that.
"I thought you knew there are quite a few people... who underestimated them like that and got burned.", Law says.
"If I remember correctly, Luffy and the others have defeated a few other warlords like you. Crocodile, Gekko Moriah, and even Hawkeye Mihawk once in the war, do you really wanna end up like them? I bet you'll be like Crocodile, title-less and wanted by the navy or locked up! Heeheeheehee!", I quip, keeping the blade to Giolla's neck.
"I'm afraid I'll have to end my alliance with the Straw Hats now. When we joined forces with them.", Law starts.
"We only needed them to destroy the SMILE factory, they weren't to kill you, in actuality, it's Kaido who will kill you sooner or later without those SMILE fruits like I said earlier.", I finish.
"I see. You two are gonna sacrifice yourselves to kill me.", Doffy says, smiling sinisterly at us.
"I want to see how the world falls into a mess after you die, but more importantly, I want to make you pay for what you did 13 years ago. JOKER!", Law says, I could feel his murderous aura easily but I didn't flinch, since I knew the animosity between them and still want to help. A glimpse of black feathers catches my attention behind us, then a somewhat warm feeling rushes through me.
"You know what I'm talking about.", Law says, a hand falls on my hair softly and I know from the aura that it was Cora-San, here to oversee Law and me.
"What is that mutt doing with Giolla? Law, you know what kind of family we are.", Doffy says.
"He's right, Law! I don't mind sacrificing myself for the young master!", Giolla says before she's shambled away by Law who catches me by my scruff and puts me down softly behind of him.
"You'd better run as far as you can, or I'll send this wild little girl after you.", Law says, making me smirk excitedly with my tail and ears sticking out.
"I'm not gonna leave the young master and run because of some little mutt!", Giolla shouts from behind Doffy.
"I don't need you. I don't need you here. Just go.", Doffy says, stunning Giolla into silence.
"Y-yes, sir!", she cries before scuttling away with her hands still hand cuffed behind her back.
"I saw Black foot earlier. Which means our plan is not going so well.", Doffy says, gearing up for the inevitable fight with Law and me.
"You lost your trump card, Caesar. You will lose the SMILE factory while your fighting us here. This will be your end.", Law says almost sinisterly, knowing I couldn't back down from the fight either.
"It's unreasonable for you to hold a grudge against me, Law! And what does this mutt know about that makes you bring her with you everywhere you go?", Doffy asks as Law sets up his room.
"It's not a grudge. And this little girl knows it. I've been living my life until today... to attain that mans long-cherished ambition!", Law shouts, slashing towards Doffy as I pull out my sword. Doffy does something that redirects the slash upwards and cuts up the fighting fish jumping towards us. Law sprints towards Doffy with me on his back before Doffy tries to nail us with his strings, I say tried because Law shambles us behind the feathery cloaked guy before slashing at him midrange which Doffy dodges easily by jumping. I take this chance to jump off of Law's back as the two clash, easily catching a non sliced bar of the bridge and using that to run up to Doffy myself and clash with him now, keeping his other hand occupied. The bridge breaks at the clashing of us, sliced into pieces.
"Room!", Law shouts, dragging me across the broken bridge and onto the main part of it that wasn't broken. I sense Doffy above us and counter him, pulling out Shirokuro's ability this time.
"Yang! Now you're fighting three people!", I shout, a black version of me appearing behind Doffy which slashed down at him as I ran towards Law.
"What's up with this girl?! Grr...", Doffy says, catching the clone I created and tossing it into the sea.
"What's the matter, Law? I thought you two wanted to kill me!", Doffy shouts, slashing up the bridge into large chunks before making us duck down to dodge another slash.
"That clone isn't gone ya know?! It'll take a lot more for it to go down!", I shout, the clone from earlier distracting Doffy in the air as Law pulls up his room.
"Tact!", he shouts as the clone is flung our way, pieces of the bridge fly at Doffy, one being sliced in half before the other pieces surround him. Doffy slices out of the pieces with ease however that leaves him open to an air attack as Law jumps up to meet Doffy in a clash once more.
"Tactic no. 1! Yang jump!", I call out, using the clone to propel me towards the fight as Law is kicked backwards.
"Cast! Yin, Yang, Yo! Spellmaker! Sky slicer!", I call, making two other versions of myself appear as the clone reappears around Doffy while Law's Room disappears. A tornado appears around Doffy once we bring our swords down, we don't actually hit him, but the force of our swings calls the tornado into existence that soon turns into a waterspout.
"This little mutt is far more trouble than I thought...", I hear Doffy mumble from inside the waterspout, suddenly, the water is sliced away and I am pushed back towards Law who catches me easily while the clones disappear into my sword.
"I can tell, you're tired Law, let me handle this...", I whisper, jumping out of his arms and aiming a swing at a piece of bridge nearby.
"Shift!", I shout, switching the charging Doffy with the rock and almost catching him with the slash.
"So your powers are similar huh? What a nuisance. I'm guessing you both had the same limits right? You've both shared duties regarding the meteorite and Fujitora, brought down and fought me once each, and rescued Black foot. I wonder how long you two can last.", Doffy says before kicking me away, making me catch myself on the bridges wall.
"Since you both are clearly similar, I know who I should be aiming for, Bullet String.", Doffy says, shooting hardened strings at Law as I hang onto the bridges side.
"Grr... how dare you do that to captain?!", I growl, my ears and tail sticking out as Law is knocked to the ground from the bullet strings.
"So she's part of your crew is she? It must be weak considering you've got kids on it.", Doffy says as Law tries to bring up his room, only to fail as the damage is done.
"That! Does it! Cast! Shift, sorry captain, but it's gotta be done.", I mumble, shifting myself with him after placing a bind on the side I was on.
"You're facing two people with similar powers, if I were you, I'd pay attention!", I shout, bringing out the three clones from earlier.
"Spellmaker! Air army!", I call, creating invisible clones and charging at him.
"I don't see anything, where's your army little girl?", Doffy asks as I aim a kick at his face, he dodges but gets caught as my clone army surrounds him.
"What is this?", Doffy asks rather calmly.
"No Taiga! Stop! You're going to faint! That's too many!", I hear Law shout, he was right, I had made too many clones but I couldn't give up, not when he was right here. A blast of air knocks me back, Doffy had broken through all of my clones which fade into nothing since they were made of air while the three colored ones fade into my sword...
