Chapter One: The Water Oasis
Chapter Summary: Following the Summit War, the alliance finds themselves on an island before they split off. When Luffy accidentally knocks them into an oasis, they come out… different.
They had finally found some peaceful times. They were all recovering following the war. The revelations that came about Ace to the world. Things that Ace learned about himself. He could barely believe any of it. That his life was taking such a drastic turn already. He could do this.
They were back in the New World now. On an island between Whitebeard and Shanks' territories. Preparing to split off from each other and having one last party before they do so. Ace couldn't be more grateful that he made it out of Marineford alive. He wouldn't even be here if it wasn't for the combined efforts of the Whitebeard Pirates, Strawhats, and the Red Hair Pirates and the Revolutionary Army. So many people had came to his rescue and he thankfully made it out alive.
Now, he could keep roaming the seas wild and free. See the world for more than what he believed it was before.
The party was in full swing, but Ace kept a little way from it. There wasn't much that he could do at the moment. Instead, he chose to walk around and take in the view of the island. It was a really magnificent place.
He paused as his eyes settled on a cave. Something about it telling him just to take a step inside. The Omega looked back at the others for a split second before he walked towards it. His hand running up against the stony wall underneath his palm. The inside smelled almost of fresh water but at the same time so intriguing. Endearing. Something that was pulling him forward.
At the back of the small cave was a small pool of water, almost glistening despite no light being within the small cavern. He didn't even have to ignite his flames to be able to see. It was almost like an oasis. Behind it was a wall of strange markings. Something that he didn't recognize. He peered down back at the water, reaching out and just millimeters before his finger hit the water, he heard, "Ace? Are you okay?"
He turned to see Shanks and Mihawk coming in after him. Shanks smiled at him as Ace stood back up to his full height. "I'm alright. Just curious."
"Oh, that's pretty." Shanks muttered, stepping forward to stand next to Ace. The red head paused, looking around, he paused as his eyes settled on the wall behind it, blinking as his jaw dropped, "That's the language on the Poneglyphs."
"The Ancient Language?" Ace questioned, turning his head to look back at it.
He kneeled down, reaching back out for the water. "Ace!" Mihawk snapped.
The Omega sent a sharp glance towards his Alpha father, "What?"
"Don't touch it. You don't know what that could be." Mihawk warned. Ace paused, letting the thought come to his mind. Mihawk was right. He could curse his curiosity for wanting to touch it, but at the same time, it felt like it was calling out. "I don't trust anything that has that language near it."
Ace nodded, pushing himself up and standing back at his full height. "Well, I guess we should rejoin the party."
"Sounds good." Shanks replied.
"ACE!" Luffy's scream echoed throughout the cave. Ace pressed his back into the cave wall. Just as Luffy came rocketing into the cave. Shanks and Mihawk had no where to go before they were being hit by Luffy and crashing into the water.
"Mom! Papa!" Ace shouted as the two disappeared into the oasis.
Luffy blinked, tilting his head as he was back on his feet. "They aren't in here."
Ace growled as he looked at Luffy. "You moron!" He gestured towards the water, "You hit them into that!"
"I did?" Luffy questioned.
Mihawk and Shanks resurfaced a second later. Huffing for air as the Alpha hauled the both of them to the edge and pulled them over. Ace could only stand there in disbelief as he started noticing the small changes about them. Shanks' face looked noticeably softer. Mihawk's hair was starting to change.
Mihawk pulled Shanks completely out of the water. The Omega wasn't even moving now. His eyes closed. A second later, Mihawk was slumping against the ground. Leaving them both completely unconscious as the two of them laid there. Ace was in complete disbelief as his eyes remained locked to them.
Ace could only blink, staring down at his parents. The two unconscious but the very clear differences that were there. Mihawk no longer had his mustache, but his sideburns remained, and he was definitely shorter than he was before, his clothes practically falling off of him. Shanks was on his stomach, scars gone from his face, no facial hair in sight, swimming in his own clothes.
Ace looked over at Luffy, shouting, "LOOK AT WHAT THE HELL YOU DID?!"
"It's not my fault they fell in!" Luffy shouted back.
"You hit them!" Ace retorted.
"I didn't know they were there!" Luffy exclaimed.
"You never pay attention, you idiot!"
Ace groaned, wiping at his face, pausing as he heard, "Son, what's going on?" He looked over his shoulder to Whitebeard, a nervous grin on his face.
"Uh… Oyaji, we shrunk our parents."
Whitebeard blinked, kneeling down almost comically from where Ace could look out of the cave at him. "You… what?"
Peering back to his parents, they were still drenched from the water they had been knocked into, only being pulled out at last second by Mihawk before they had fallen unconscious. He had no idea how to explain this. Sure, he didn't even know how it happened in the first place.
"Um…" Ace started, unsure of the words to say. "They are smaller."
"They are smaller?" Whitebeard questioned, almost like he was trying to comprehend what Ace was saying.
Ace grinned again, giving out a nervous laugh as he looked at Luffy. "What do we do?" Luffy questioned.
"How am I supposed to know?" Ace immediately questioned back.
Neither of them could say anymore as they heard a groan behind them to see Mihawk moving, rubbing at his face before he was blinking his eyes open. Pausing as he looked over to the Omega that was still unconscious on his arm. "What the hell?"
"Um, Mihawk, don't freak out." Ace muttered, gaining the Alpha's attention.
Mihawk's hand immediately went for Yoru as he shuffled to put Shanks behind him. "Who the hell are you?"
Oh. Just. Great.
They had amnesia too.
Mihawk was now in a kneeling position, keeping himself as a shield between them and the others, pulling Yoru from its sheath. "You have one second to tell me what is going on or I'll cut you down."
"Good luck with that." Ace mused, sighing as he said, "You were adults and now you're… um… I dunno what age you are, but you got turned smaller."
Mihawk sent a sharp glance at him as Shanks started to wake up behind him, holding a hand against his head as he pushed himself up. "I feel like I drank too much." Shanks whispered before he was looking up and blinking at them. "What's going on?"
"I've got this, Red-Hair." Mihawk growled, not even turning his head to look back at Shanks. Ace was able to get a better look at them now. With the way that Shanks' shirt fell off his shoulder, he could clearly see the missing bond mark that should be there but wasn't. He tried to rack his brain for anything that he could remember Shanks telling him about his younger days. Shanks didn't look much older than fourteen, maybe fifteen. Mihawk looked slightly older than that, but it was hard to tell for sure.
How was he supposed to explain that they were adults with two kids together and said kids were standing right in front of them?
"It's alright, we're—" Luffy started but was stopped by Ace's hand covering his mouth. The motion causing Mihawk's eyes to narrow.
"My name is Ace and I'm the Second Division Commander of the Whitebeard Pirates." Ace stated, bowing slightly, forcing Luffy down with him.
Shanks gave him a puzzled look, tilting his head slightly as he muttered, "That can't be right. Portgas D. Rouge is the Second Division Commander." He stopped for a second as he looked around, "This isn't Loguetown… at least, I don't think so." Shanks looked beyond confused as he looked around, his eyes settling on Ace for a moment. Eyes narrowing for a second as he tilted his head to the side.
Mihawk growled, pushing Shanks even further behind him. The Alpha was attempting to use himself as a human shield between them. Ace was positive that he could feel their power levels. They were both powerful in their own right. It just felt off that Mihawk would act like this near them. In this situation, he didn't blame him. Neither of them seemed to have any recollection of anything past the ages they looked like now. This was just odd all the way around. This was going to take a lot of explaining towards the others. "You're lying." Mihawk accused.
"He's telling the truth!" Luffy shouted. "My name is Monkey D. Luffy! I'm the Captain of the Straw Hat Pirates." He said, motioning to the straw hat on his head, the wide grin on his face.
Shanks' eyes widened, "Wait! That's…" He paused, hand reaching out to grab Mihawk's bicep. "I don't think they're lying, Hawkeyes."
"We sure aren't." Luffy replied as Ace finally released his head. "You're both supposed to be old." Ace elbowed him in the side, giving him a look. "Sorry."
"Why do you have that hat?" Mihawk questioned, his attention now completely on Luffy.
Luffy grinned. "Because he gave it to me like ten years ago."
Shanks shook his head in disbelief. "I wouldn't." He muttered. "That hat means more to me than anything in the world. I would never just give it to anyone. Especially someone I don't know."
"Trust me when I say… you know us quite well." Ace stated. He sighed as he noticed both of them still looked weary of their presence. According to Shanks' own words, his last known recollection was of Loguetown. From what Ace could remember, that would place him at about fifteen years old. He stopped as he grabbed Luffy's arm, pulling him towards the entrance of the cave. "Hang on a moment."
"Ace—" Luffy protested.
Once they were at the entrance, he stopped to look at his brother. He shook his head, still in disbelief of what was happening. Maybe it was that language on the wall that could tell them what was going on. He didn't have a clue what to do. Hell, he didn't even know what happened. All he knew was his parents were now a lot younger. Shanks probably being the youngest here aside from Luffy's doctor in the form of Chopper. He exhaled sharply as he leaned back against the rock. "Luffy, you need to give the hat back."
"What?!" Luffy exclaimed, reaching up and grabbing at his hat. "I'm not supposed to give it back until I'm a great pirate! Our promise!"
"Luffy!" Ace replied, cutting through Luffy's talk. Of course, he knew of the promise. What it meant to the both of them. What it meant to Luffy. That hat was Luffy's greatest treasure. Something he valued almost more than anything, but that wasn't the case right now. "Luffy, he's fifteen at most. He talked about Loguetown. He…" He motioned towards Shanks, where he could see the Omega speaking to Mihawk in a hushed tone before he turned his head back to Luffy. "He doesn't remember your promise. He doesn't remember us. He's younger than before he was pregnant with me. Luffy, you have to understand that at the moment, for him, that promise doesn't exist. In his mind, he just lost the same man who gave him that hat. Just return it for now. Once we figure this out and get them back to normal, take it back."
Luffy sighed, reaching up and pulling that hat off of his head. "This… this is going to be weird."
"I know it's a lot to ask, Luffy, but trust me on this." Ace stated.
Ace's attention was taken away by the amount of people who were now standing by the entrance. He had that nervous smile back on his face. "Son, what did you mean by you shrunk your parents?" Whitebeard questioned.
Ace wasn't even sure how to answer it. "Um… about that."
"They look our age!" Luffy exclaimed, pausing as he frowned for a second. "Though, they don't remember us."
"They don't remember you?" Rouge questioned, looking even more puzzled by the second.
"I don't know what happened. They fell into water and now they are… small-ish?" Ace replied. "Mom recognized the text on the wall from the Poneglyphs."
Before any of them could say anything, Ace could hear an exclaim of, "Mihawk, no!" Mihawk came out of the cave. Yoru braced in one hand, holding his pants up with the other with a scowl on his face. "Stop it, would you?!" Shanks wasn't fairing much better. Curling his cloak around him. Sword and pants in his other arm.
"Someone is going to tell me what the hell is going on!" Mihawk snapped. While his face looked intimidating, the rest of him didn't. He was struggling to keep his pants up while also trying to appear like he was ready to strike. Ace was sure that he could, but the idea had him cracking up.
Jaws around them dropped as all eyes landed on the forms of Shanks and Mihawk. Ace just turned to look at Whitebeard again with a shrug. "See… small."
Shanks was looking at all of them with wide eyes, mouth dropping open for a second before his eyes settled on Rouge. A grin breaking out on his face, "Commander Rouge!" It felt foreign to Ace's ears. This wasn't something he was used to hearing from Shanks. He knew that a long time ago, he used to refer to his mother as her position and her name, but he had never actually seen it. It was almost like it was a second nature to Shanks from what he could see.
Rouge gave him a soft smile, reaching out and tucking some of the wet hair behind his ear. "Honey, they know you're my son."
Shanks stopped, looking around again. "They do?"
"Yes, sweetheart. They do." Rouge confirmed.
"How?" Shanks whispered, pulling his cloak even closer to himself. Ace was able to catch his scent even more now. It wasn't as mature or sweet as it was before. Almost like it hadn't matured yet like it came with age. Mihawk's wasn't much different. It was just completely odd in general.
"It's a long story, Shanks." Rouge muttered, reaching forward, and wrapping her arms around Shanks. "Just… they know everything, sweetheart."
Shanks seemed to relax in Rouge's hold, leaning his head against her chest. His eyes fluttered shut as Rouge's fingers started moving through his hair. A calming gesture. Ace didn't miss the way that Mihawk still seemed to linger around Shanks, sharp glances being cast towards the rest of them.
"You said the walls had the Ancient Language?" Robin questioned, stepping forward to catch his attention.
Ace turned his head and nodded. "Yeah. Mihawk told me not to touch the water." No one seemed to miss the way that he had used Mihawk's actual name instead of calling him his father. No one commented on it for the time being. "Luffy knocked them in, and they came out like this."
Robin hummed. "Give me a moment. I'll see if it will tell us anything."
"Why don't we just throw them back in?" Luffy questioned. "That might fix them."
Ace cast Luffy a look of disbelief, shaking his head. "That's how they turned out like this."
"Maybe, it will change them back." Luffy immediately replied.
Ace groaned, rubbing his palm over his face. He loved his brother, but at times he could be the biggest airhead he knew. "So, we are really supposed to be bigger?" Shanks questioned.
Ace hummed, placing another smile on his face. "Yeah, the clothes you are carrying…" He paused motioning to the clothes in Shanks' arm. "They were what you were wearing when you got pushed in. You are actually supposed to be thirty-seven and Mihawk is supposed to be forty-one."
Shanks eyed the clothes for a second placing a grin on his face. "This can't be so bad, can it?" He stated. "This had to have happened for a reason."
Whitebeard snorted, chuckling for a second that had Ace looking up to his Captain. "How did I never see it before? That is exactly something Rouge would say."
Marco laughed slightly. "It's all there. The cherry blossom scent. The smile. The way he acts. We had seen it all and not one of us had put the pieces together." He added. "Even now, that I can actually smell the strawberries, it's obvious who his parents were."
Shanks pulled away from Rouge, his eyes settling on Ace and Luffy again. "You two…" He muttered, taking a step forward, getting closer to Ace's face now. "I'm related to you two."
Ace could only let out that nervous laugh again. He didn't know how to explain to the two of them who him and Luffy were. Luffy went to open his mouth, but before he could actually speak, Robin was walking back up with a grim look on her face. "The writing, it says that the water they fell into it a fountain of youth of sorts. It didn't say a way to change them back. Just, fate will lead the way."
Ace froze, his eyes turning to Shanks and Mihawk. They could be stuck like this? This wasn't good at all. He didn't even know what they could do to somehow figure this out. What could they do now?
