Chapter one: Hope of the return

I sigh as I walk through Diagon to the bank. Yukina followed me while keeping everyone away from me. The Goblin's smirk upon seeing me causing me to pause and give my fellow warriors a bloodthirsty grin as I greet, "May your enemies fall to your mighty Axe and spear while your gold flows like their blood onto the snow. Greetings my friends is Ragnok back yet?"

"May your enemies fall to your scythe as your claws tear them limb from limb while your your gold flows like your spirit," The goblin on the left, Tripclaw greeted, "He's back...thinking of causing some more chaos this morning Ashferd?"

I grin and nod, "I am...after all Dumbledore must die for bringing me back here."

The one on the right, Falloblood commented, "You should get inside. He was rather eager to see you."

I nod and bid them goodbye before heading inside. I gave a grin to every goblin I passed as I made my way to my favorite teller. I stop before him as I waited for him to be finished. Griphook was the first goblin I had ever met and is a good friend. He looked up and we greeted each other before I say, "Griphook I need to see Ragnok. If you can be pulled away from you duties, I request that you help me out today."

He rolled his eyes, "So polite little wolf. Follow me please. Ragnok was oh so pleased when he came back."

I snicker at the thought as we began to make our way to Ragnok's office. Yukina had shifted into her Hawk form the moment the door closed, so the goblins on the other side could move freely. We soon reached the ancient golden oak door and walked inside. Ragnok sat at his desk as he mulled over papers and various other things. I spoke after he had put down his quill, "Damn you must be bored old friend. May your enemies fall to thy blade as your gold flows like a mighty river."

He jumped slightly before giving me a glare with a small smirk. He gave the greeting before saying, "I wish you wouldn't do that."

I shrug as I reach up to stroke Yukina's head while saying, "Not my fault when you get too deep into your work...I did wait for you to put down the quill this time, so it wasn't too bad."

He nodded with a sigh, "I will give you that...now shall we conduct our business?"

"Must you even ask?" I retorted as I took a seat with a grin, "Let's get to the point where I get to shove Dumbledore into my little happy place,"

The goblin's in the room grin at the mention of my happy place. I had started building it when I first found out about my ability to create pocket spaces. It was a place where I could put people who annoy me to the point I need to watch them suffer until they die. It was filled with sand and fates knows what else ...monsters mostly that I had either summoned or found. I did give those that went in an equal chance of survival and a chance at my treasure vaults...Nami had gone crazy when she found out how much I had in the vaults...it was all the treasure I had gathered plus some neat little things I picked up along the way. I gave anyone who got shoved inside of it a chance to reach my vaults and take a single thing from the various things inside. They would be able to leave once I found out they had reached the end...no one has ever done so because the entrance moves every five minutes to various places in my desert world. I also had trap rooms filled with things to drive people crazy...yeah so Dumbledore has earned himself a place in it. I gave Ragnok a pleading look and he smirked as he took out a box. When he opened it, I gasp at the beauty of the things inside...Jeweled scarab beetles...They will eat you from the inside out, but are so amazing when they're in their shells. Ragnok spoke in a prideful voice as he said, "I was able to get these from a merchant in egypt at a low price. I assume you have everything that's needed to keep them?"

"I'm not an idiot you know," I murmur as I took the vaults and handed over a scroll, "I know you have some extras. The scroll contains the spell to keep these things in their shells. Use them wisely and remember they do multiply so be careful with it,"

He nodded and I put the scarab's in my pocket space for later enjoyment. We then settled down to talk about normal bank things before I collected the deed to my island and went down to my vaults to grab what I would need for today. I headed outside the bank with Yukina by my side and went about my shopping. I gathered my school supplies and some extra books before having my head house elf, Mipsy take them to my room on the island. I then went for ice cream and a quick meal before heading back to Grimmauld. I enter the door just as Moody came up. I gave the old auror a nod before I made my way into the house. I stopped by the drawing room and found Sirius still arguing with Mrs. Weasley. I caught his eye and grin at him with a thumbs up. He snorted and continued to argue with the idiotic woman. I rushed upstairs to my private room and made sure no one had tampered with anything before I lay down and fall asleep.

Dreamscape

I was in the forest again...my heart started to race as I quickly made my way to Luna's grove. Could this mean I could go home? Please let it mean I can go home. I broke through the trees and found Luna standing there with Davey. I spoke after a few minutes, "Can I go home now?"

Luna shook her head sadly causing my hope to plummet like an anvil towards the ground, "Sorry Kai...we cannot take you back..."

I felt grief fill me as I slowly fell to the ground. My fingers curled around Law's ring as tears streamed down my face...why were the fates so cruel? Why me? Why? I felt arms curl around me as Luna hugged me. I must have said something because Luna murmured, "But that doesn't mean anything...you're family will be here...very soon. They just need to find a portal...they will be guided by both Davey and I. I promise my friend, They shall come here..soon."

I felt hope rise in my chest just as Davey spoke, "Now we've come with another...fact that you should know...it is your birthright after all."

"What do you mean?" I ask in confusion causing Davey to smirk as Luna groaned.

"Your parent's are alive...they just don't remember you yet," Davey announced causing me to stare at him.

He has to be insane...how-"How in the hell can they be alive. I saw my mother die right before my eyes!"

He grinned and said, "Ah you saw her mortal shell fall. Your father is the same."

"Mortal shell?" I question causing Davey to smirk.

"While they might not be as strong as us," He began as Luna groaned, "They can take true mortal form by casting their power and memories aside until death,"

My eyes widen as he said that...that would mean that they were...I was, "They were gods?"

"Yes," Davey announced, "Only they are a part of two diffrent pantheons...so you're a demi-goddess in both due to your mortal blood,"

"So they don't remember me?" I ask causing him to nod.

"Yup, but they should remember soon," Luna answered causing me to look towards her, "The killing curse caused damage to their memories, but as soon as they get them back...They will be coming to see you...most likely kill Dumbledore and the Dursley's,"

I grin at that before saying, "They can do what they want to the Dursley's, but Dumbledore and Mr. Flight from death are mine to kill," I then asked, "When should they be getting their memories back?"

"Half way through your school year...perhaps maybe at the end depending on how long it takes for them to heal completely from the damage," Davey answered causing me to nod, "They love you Kai...make no mistake about that, but Shanks, Mihawk, and Makino are your parental figures,"

"I hope they get along," I say before the area around me began to dissolve, "I'll see you later,"

With that I disappear from the lands of never never...

End of dream

I open my eyes in the real world just as the pounding on my door increased. I groaned and checked the time only to yelp...I'm late. I quickly got ready before having Mipsy give me my things. I headed out the door where Hermione gave me a seething look as she said, "About time Kai."

"Sorry I was tired yesterday," I say causing her smile slightly as we made our way downstairs, "So plan kick Dumbledore out of Hogwarts is a go this year?"

"Why not," She mused, "After all we are in our fifth year and from what I've heard about our new teacher...bad things will happen...did you find the locket?"

"Who do you take me for?" I ask as we got onto the landing, "I have already taken care of it with the help of my summons. We only have that snake and the ring to worry about,"

"I see," She murmured as we slowly made our way into the kitchen where she took a seat, "So we'll be using that portal of yours to get to the station?"

"Yup," I answer as I began to make us breakfast, "We should get going right after we finish eating. Hopefully the troll and his gang will leave us alone this year..."

"Yeah right," She retorted, "He's tried to feel me up the entire time I've been here...not fun,"

"You did hit him with a book right?" I asked causing her to blush, "The twins will be getting revenge this year so it's all good,"

I let out a yawn once I had breakfast finished before I set the table and we began to eat. I finished first and began to wash the dishes until Hermione was done. Once that was over, we grabbed our things and made our way out of the house. We went into the backyard and I summoned my scythe before cutting us a portal. We went through it and Hermione fell to the ground with a groan causing me to snicker softly. She laid there for a few moments before standing and glaring at me, "Not funny," She grumbled causing me to snicker, "It's not funny Kai!"

I snort and say, "We've used this method of travel enough for you to get used to it...maybe I should reconsider having you join the straw hats," She paused causing me to snicker again before I began to walk towards the station, "Come we must hurry if we want to get a good compartment."

She scrambled to follow me and I mentally thanked the moon for having a good house elf. We quickly boarded the train and find a good compartment. We started to set up wards and the like to keep out unwanted annoyances before sitting down. I lent her a book on advanced runes while I began to read another advanced book on seals. Fred, George, Luna, and Draco quickly made their way into the compartment an hour later as the train began to leave. I look up to see Neville and Susan taking a seat as Tracy and Daphne entered. The two took a seat next to me and leaned against me causing me to chuckle softly...Law and I had an interesting relationship when it came to our own genders..after all he was the one to say that if we're separated for long periods of time we could look at our own gender. I shook my head lightly before I continued to read my book. Tracy borrowed my non-magical world mystery stories while Daphne borrowed a book on greek tales. We all were silent for a little while before Neville broke the silence from his place next to Susan. He commented, "So what's the plan this year?"

"Cause unholy havoc on those that have wronged us and graduate from Hogwarts," I answer as I put my book away, "after all we can take our newts and Owls at the testing posts set up all over the world, so why not make this our last year. Students that go to magical school must have at least 4 years at their school before they can take the tests. So why put it off when we're smarted and stronger than the rest?"

Daphne cracked a smile as Tracy said, "There's our best friend! So what are we going to do with Dumbledore at the feast?"

"Paint bombs and a little vial of water I got from a cursed spring back in the Grandline," I answer with a grin causing them to gap at me, "What?"

"You would use one of the only things that connect you to your Nakama as a prank?" Hermione asked causing me to nod, "Who are you and what have you done to my sister?!"

I roll my eyes as I say, "Hermione it's me...after all I'm the only one you told about your fear of gigantic pink pigs...where that came from I will never know," She blushed and I rolled my eyes again at the incredulous looks I was being given, "Besides my family will come for me soon...after all they will end up finding a portal that leads to this world."

"Who told you that?" Draco asked causing me to grin.

"Lady Luna and Lord Davey...you'll never guess what else they told me," I smirk at the looks on their faces, "Guess,"

"That you're really a princess and are going to be married to a runaway prince?" Susan said causing me to toss a ball of ice at her...she dodged with a laugh, "Alright I was kidding,"

"Not funny," I growl to the amusement of the others in the room.

"You're a galactic space pirate bent on world domination and wish to have Daphne and I as your queens?" Tracy asked causing me to roll my eyes.

"Nope though that does seem like a good plan if all else fails," I murmur causing laughs to erupt, "Only you two would end up being my heads of state whereas Law would be my king...well that's if Luffy would defeat a giant space squid with a toothbrush and sparkles,"

Laughter erupted once more after I finished saying that with a straight face. Daphne shook her head after a few moments, "Only you two would come up with something that bizarre...wait add Luna to that list after all she did say we would all be turned into white mice and go live in an old clock that was inside an ancient castle with an ogre as the king," I shook my head at the memory of that day...too much sugar...though Luna did look- ya know what that's a scary thought...I shook my head again as Daphne said, "They told you that you were the actual daughter of Shanks, Mihawk, and Makino?"

"Nope though I wish I was," I murmur cause them to give me sympathetic looks.

Fred and George looked at each other before Fred began by saying, "They told you-"

"That you would be-"

"the next pirate queen-"

"After Luffy gave up the crown-"

"To marry Boa Hancock-"

"And live on a farm-"

"Raising snakes and other animals-"

"While singing a song about-"

"True love and pink butterflies-"

"Dancing in the rain?"

"No though that does sound entertaining," I say while shaking my head in amusement, "Plus, Luffy would never give up his title unless truly wished to or found a reason to do so,"

Draco went next, "Did they tell you that on your 18th birthday you would be given the power to create as many sweets as you want whenever you want to?"

"No, but that would be an amazing power," I groan at the fact I couldn't do that while pouting.

"Did they tell you," Hermione went next, "That if you keep up torturing Dumbledore you will eventually grow bored?"

"Fuck no!" I yell causing laughter to echo around the room once more, "I will never grow bored of torturing that damned man. After all I need to get revenge on him for bringing me back here. You're important to me, but I want to go back home,"

I got nods before Luna said, "They told you that a wakaspurt has taken over your home and now you must fight it with flying peanut butter and jelly sandwiches as it attacks using it's fluffyness and tentacles?"

"Nope," I say nearly choking at what she had said before I realized that she was friends with me...so it's to be expected, "They told me..."

"Tell us!" They demanded causing me to pout at them.

"Pushy," I mumble before saying, "James and Lily are alive. They are two gods from two diffrent Pantheons and with my mortal blood it makes me a demigoddess. They lost their memories of me when they were sent out of their mortal forms. They should be remembering me around the middle to the end of the school year,"

"Who are they then?" Hermione asked causing me to shrug.

"Lady Luna and Lord Davey never said anything, so I got nothing," I say with a shrug, "It doesn't matter anyway..it just means that their laws don't affect me...not that they ever did..."

We fall silent before we began to plan about how we would do the prank before deciding on using the house elves. I call the head house elf of Hogwarts and he does as I commanded due to the fact I am the heir to three of the hogwarts houses being Gryffindor, Ravenclaw, and Slytherin. I yawn lightly and fall asleep as noon came upon us.

Time skip

I sat with Hermione and Neville at Gryffindor table waiting to eat. The food is soon served and we eat slowly before turning towards Dumbledore. He let out a cry of shock as the lower half of his body became that of a goat and a pair of ram horns grew from his head. I snicker softly as laughter rang through the room. I grin when it disappeared a few minutes later after all it would affect the bastard for the rest of his life. I snort as Hermione said, "Five minutes until the school song. When he announces it, the bombs shall drop."

I smirk and she proved correct a few moments later as Dumbledore stood. He spoke in his grandfatherly voice as he looked around the hall, "Now that we are full. Let us sing the school song-"

The bombs dropped all around him and nailed many students and teachers a like. I allow myself to be hit with a matalic silver paint bomb and grinned at my friends as Dumbledore tried to calm down everyone. We were soon sent to our common rooms and I silently sent a message to everyone, "Dumbledore will do anything to blame us and with that ministry toad we will have a hard time this year. Use everything you got to keep from doing anything stupid."

I got a resounding agreement as I laid back in my bed. I had the bed that sat under a window which made me happy. Yukina curled up next to me as I began to play with the ring around my neck. It was a dark obsidian black with sapphire and diamond paw prints. I smile sadly as I stare at the moon...soon we'll be together again Law...soon we'll all be together. I fell asleep as the night wore on...glad that tomorrow would be a saturday...

Time skip morning

I yawn as I got up before I left the room to go for a run around the lake. I use the fun way to get down the stairs before I landed with ease on the first floor. I walk out of the doors and into the weak sunlight. I stretch lightly before I began to run and soon I was joined by Luna, Tracy, and Daphne. They smiled and the others joined in moments later. We ran for a while before heading inside to shower after which we headed down to the Great hall. We began to eat when suddenly storm clouds gathered and tension rose. I felt my heartbeat quicken as lightning struck the lake. I gasp just as Dumbledore, Mcgonagall, and Snape left the room and sealed the doors. We continued to eat, but for some reason I couldn't sit still. I heard the roars of battle and gathered with the other students at the windows...Marine's were attacking...fuck. I quickly unsealed the doors and ran outside where I stood by my head of houses side. She glanced down at me as I hastily casted a shielding charm on us. She yelled, "What are you doing out here?"

"Helping!" I yell back, "I fought guys like these back in home. I know how to get rid of them," I gave her a look that said I knew what I was doing, "I need to fight,"

"Alright," She shouted, "Just don't get yourself killed or else I will never forgive myself,"

I gave her a quick nod as I summoned a group of animals to attack the marine's. They tore through the idiots as I fought along side them using both magic and my elemental devil fruit powers. I heard a shout just as lightning struck once again...this time it was a pirate ship, but I didn't pay attention to who it was...my attention was locked on Mcgonagall where she was fighting a marine, but one had snuck up on her. I quickly replace myself with her causing the attacking Marine's blade to sink into my shoulder. I wince as I killed the man before taking the blade out. I shot forward and began to fight with the blade even if it didn't feel right. I slammed into the nearest marine just as shouting echoed. I ignore it as I continued to kill the marine's with a sadistic smile on my face...this is where I belong...fighting these idiots. I felt a blade sink into my chest and stare at it...it wasn't in a fatal place, but it hurt like a bitch. It was just under my heart and in between my lungs. I wince as I took the blade out and tossed it at the marine as fire rained from the sky. I felt blood rush in my ears as I continued to fight...my lungs burned with each breath I took and my chest hurt. Only when the last marine fell, I allowed myself to fall to the blood stained ground. I heard the rushing of feet as my vision started to turn black. I saw a flash of blonde hair before my world turned to black.

Time skip 5 days

I wince as I woke up. The scent of the infirmary clouding my nose causing me to gag. I felt a soothing hand and look up to see Luna smiling at me. She spoke in her usual mystic tone, "Hi Kai! Good to see your awake."

"What happened?" I ask after a few moments, "All I remember is blacking out after killing a bunch of marine's and seeing a flash of blonde hair,"

"A group of pirates appeared and helped kill the marines," She answered with a smile, "They seemed to know you, so Dumbledore brought a group of them into the castle while the others got rid of the bodies. The nargles tell me that the fiery one will show up as soon as he can...he's caused a lot of damage to the old coots office,"

"When can I leave this hell hole?" I ask after a few seconds and realizing that Whitebeard was here.

"In a few minutes, Madame Pumfrey just wants to make sure you've made a full recovery," I grin at that just as the healer bursts into the room.

She clucked her tongue at me as she checked me over before giving me the all clear. I got up and walked out of the room with a grin as we headed downstairs to eat. Turns out I had been out for five days and another group of pirates had appeared...they happened to be the Kuja pirates. I followed Luna into the great hall where silence rang through the great hall as all eyes turned to us. I almost fidget from the stares, but made my way to the table of lions where I sat next to Hermione. She handed me the notes for class that she had written down for me and I began to look them over before turning to the hall and saying, "This ain't a zoo people. Eat your food or get out!"

They turned back to their food, but they would glance at me frequently. I ignored the talk as I read over the notes before placing them on the table and eating my food. I finished up quickly and headed up the stairs to my dorm where I took a shower before curling up on my bed. Hermione came in moments later and began to brush my long hair for me since she knew it would help keep me calm. I hate being stared at. Hermione spoke after a few moments, "You can't really blame them. You did just masacre a lot of marine's. They are just children and the memories you've shown us don't even compare to what it actually looks like."

I snort as she finished and I began to brush her hair, "They should get over it. They would have seen it soon enough. The moldy idiot has racked up the body count during his first stint as a dark lord that is a lot...not as much as regular marine casualties, but still a lot."

"True," She murmured before asking, "You know the pirates that came?"

"Yes," I answer, "The whitebeard pirates and the Kuja pirates are cool. The Kuja pirates are very...dangerous to men and women as I am sure you know,"

She snickered and we curled up on my bed and fell asleep. Class would be boring, but I had to go through it...for a little while.

Timeskip 2 days

I growl under my breath as I trudge into the great hall. I took a seat next to an equally drenched Hermione and Neville. We grabbed our food and I had Mipsy bring some pepper up potions for us to drink. I ate my food and ignored the world around me until the water dried midway through lunch. I got up and headed upstairs to grab a shower before I headed to the library to read and relax. I had just curled up with a book when the door opened. I glance up to see Marco entering the library with two other members of the whitebeard pirates. I froze slightly when he glanced around and saw me. He walked towards me and I smiled at him. He stopped before he reached me and said, "Hello Kaileara. It's been a while."

I nearly smirk at the laid back phoenix and say, "It's been two years for me what about you?"

"6 and a half months," He answered causing me to grin, "What have you been up to?"

"Chaos and having fun while turning people towards my demented ways," I say causing him to laugh.

"So the usual," He commented.

I nod before asking, "So have you finally gotten my pyro of a brother or is he still playing hard to get?"He froze and I glanced down at his hand...a gold ring with a phoenix engraved on the metal...I grin at the blonde and comment, "So my brother finally had the guts to ask you out and propose to you," He nodded after a few minutes causing me to sigh in relief, "About damn time. I was starting to think that I would have to lock you into the galley until you admitted your feelings..or killed each other."

"Really Kai?" He shook his head before I could answer, "Actually don't answer that. I already know you would have done it," I gave a large grin before hearing my name being called.

I glance past Marco and found it was Neville. I curse realizing what time it was and stood up. I turn to Marco and say, "Sorry, but I have to go train a few of my minions."

I heard him laughing as I took off. I left the book where it was before following Neville through the halls and up to the room of requirement. We met the others and began our meditation. They would be finding their animagus form or forms. I would be working on my energy manipulation. With a deep breath, I submersed myself into my energy and began to test my limits and control the flow. I was shaken from my meditation as a loud boom sounded. I open my eyes and got up before I took off running. I jumped from one of the high windows and landed next to Ace. He glanced towards me and stared for a few moments until Pop's spoke, "Kaileara it's good to see you up and around."

I gave a feral grin before looking at the marine ship, "Please tell me they have someone worth fighting on that thing."

I heard laughs and felt Ace wrap an arm around my shoulder as he said, "That's the sister I always knew. I'm sure there's something after all the ship is kind of big."

I smirk at my brother and said, "We'll talk later, but for now let's have some fun," I then focused on the ship as Marine's began to unload, "Shall I start this off?"

I got murmurs of agreement and created a dragon of ice and a dragon of fire. The duo attacked the ship and tore into it's hull. Marine's jumped off the ship and we began to attack them. I summon my Katana that I named Bahamut. My blade sang through the air as it cut down the marine's in my way. I soon ended up back to back with Ace who grinned at me. He said, "This brings back memories."

"Yeah," I grin, "All we need are some giant tigers or something and it'll be like when we were kids since these guys are like bandits,"

The marine's seemed to take offence and began trying to land hits. I easily dodged the hits by coating those area's with thick scales or something. A large crack sounded as another pirate crew appeared while fighting some marines. I nearly grin at the sight of the flag. Ace looked over and let out a groan. I snicker as he said, "Really why the hell does it have to be Bonney?"

I let out a loud laugh as the Bonney pirates started to fight as well. I say, "Because I need someone who can eat as much as me and help me pull shit on Dumbledore!"

He let out a groan and went off to fight with Marco. I quickly maneuvered my way through the marine's and killed the man who was about to attack Bonney from behind. She glanced towards me and grinned as she turned a marine into an old man and say, "Long time no see Kai!"

I grinned at her as I slash at another marine, "Nice to see you to Bonney. Now why don't we get rid of these idiots."

She smirked and we continued to fight the marines before we raided their boats. I made sure to grab some of the books they had before I returned to the school. I washed off before heading down for dinner and sitting with my friends. We ate for a while before Bonney and he crew walked in. They spotted me and took a seat as they began to eat. I nearly grinned at the looks they were being given and the fact the attention was finally turned away from me. Bonney spoke after a few moments, "Law misses you a lot."

I nod with a sigh, "I miss him as well...how has Luffy been doing?"

"Pretty well," She said before tearing apart a roast beef sandwich, "How old are you?"

"15," I answer with a smirk.

"Law will be happy," She said before asking, "So who are the two girls at the snake table that are looking at me like they are wondering if I'm trying to steal you away from them?"

"Daphne Greengrass and Tracy Davis," I answer with a shrug, "They are my girlfriends,"

Hearing that she choked on her food before staring at me in shock. She stuttered, "W-what?!"

"Yup they are my current girlfriends though it's more like friends with benefits," I shrug lightly as I dug into my steak.

She stared at me for a few moments before saying, "I do not get your relationship with Law at all."

"You don't need to," I say with a shrug, "It's mostly to keep us from going crazy without each other. Let me guess he's been traveling with the Kidd pirates for a little while?" She nodded causing me to smirk, "Think about why," Her eyes widen to the size of dinner plates causing me to laugh before I stood up with a sigh, "I'll see ya later. I need to get some sleep. I'll see ya in the morning."

Okay well that's the first chapter.
