A new adventure, secrets and a plan ready to be set in motion.

Prompt

Notebook/diary

A single step outside, a new adventure lingering on the horizon, one where they didn't need to fear war, about being dragged into a fight they'll be forced to train harder for. This was an adventure where finding oneself, will be mixed up between love, the need to protect and discover something to either fill a void or recall fragmented memories.

Daniel hopes to gain something he'll cherish…

Killua hopes to regain the one he cherishes…

Alluka wishes to see the two smiles once more, to have an adventure of endless smiles.

Each dream was depended on whether or not something goes their way, but just because the door to the Darkscryer's home was now closed, doesn't mean it would forever remain like that. They had so many adventures to explore, a list of ten names of people whom could shed light on Vastorie's past, making even the darkest of hearts shine brightly in an empty room.

It's something Daniel must learn, even if it contradicts what he already knows, he must for the sake of himself as well as his sanity.

Nathaniel was already there to greet them at the door, a soft smile shining brightly on them. He couldn't wait to ask, pulling the three into a welcoming hug, one which radiated a goodbye with a 'please come back soon' vibe.

He didn't want this to be the end, but rather the beginning to where the future will lead them back into his arms, a family once more, where Vastorie no longer feels alone like he thinks he is.

He has gotten to know the two siblings over these last few days, cherishing them like his own. While he couldn't outright declare he loved Killua like a son, he should at least let him know through other methods. "I'll miss you," Nathaniel hummed into the nape of his son's neck, "please come back soon."

"Alright, dad, you're crushing us."

With a smile he pulled back, looking at Alluka "You too missy, you're now like a daughter to me, so I expect to see you return with so many stories, no matter if they're embarrassing or not."

Alluka slipped her arms around Nathaniel, smiling brightly, "I will…" Yes, this man wasn't related to her by blood, but like him, she saw him as an irreplaceable father figure, a dad she wished to keep.

Raising a single hand so that he wasn't forced to let go of Alluka, he poked Killua's nose with a smile "Rules apply to you too! A caring sibling is as much as a son as my own. Protect your little sister…"

Killua could see it across the man's face, how much he wanted to really say more, but that fear of Daniel's rejection kept his mouth shut, words only able to be voiced telepathically. But if he had to guess, Nathaniel so badly wanted to say he loves him like a son, that he wishes him the best, to find a way to bring Daniel's memory back. He wants him to be as happy as his own son, to continue protecting Daniel.

Killua turned away, cheeks flushed from what he imagined Nathaniel wanting to say. But he can't deny these past few days means a lot to him. His father would never act like this, accept him without rules and regulations. He sees him as his blood son, a prodigy Zoldyck in name only. Yes, while the love was portrayed in a sick and twisted way, he cannot deny his father loves him. He just wished that form of love, wasn't attached to being an assassin.

Killua gave the man a quick hug, not wanting to alert Daniel of his true feelings. He knows that a part of his mind will miss Nathaniel, no matter if it leaves him flustered or not. He only wished that they left on a higher note, as he was sure, Alluka wished to stay longer.

Nathaniel turned to his son. He knew Killua would struggle at this time to get his son to go after his sister, so rather than getting his son to bounce around the issue, he could at least instil the idea that his son should go after her himself, "Now, I know you don't want to find out a little more about Vastorie right now, but at least understand where he's coming from… he is not malicious, evil, or a monster…"

Daniel frowned, he didn't think anything differently from Vastorie. Yes, he hates him for thinking so little of him, but before that moment he snapped, honestly, he didn't regret coming home. Whether Killua was the cause of the breakdown or not, it's up to him to find out. Nathaniel wants him to travel with Killua, and he highly doubts that he wants him to travel with the man whom single-handily destroyed, not only his family, but Alluka's happiness as well.

That kiss he walked in on, showed him he cared for Alluka, the way his warm expression would smile at Alluka, even if he isn't physically smiling.

It will be up to him to decide whether or not he wants to stay with Killua, but right now, he does want to help Alluka, even though now he feels like he's forgotten why he made that promise to her in the first place. With a sigh, Daniel disagreed with his father "I don't despise him… And yes, I want to understand what or who made him snap like this."

"Good," Nathaniel smiled, letting go of Alluka as he paid close attention to his son instead. He wanted to choose his words wisely, and make Killua's situation a lot easier "Then, it's best to start with Zaikaria. Her… skillset, has made it easier to understand Vassie,"

"Wow, I haven't heard you call him that in ages."

Nathaniel laughed "It has… but, Zaikaria is one of the few people have gotten into his brain. She'll understand him the most."

"Right, so where is she…?"

"Yorknew on unknown business. Give her a call when you get there. Hopefully, she'll be willing, or at least able to meet."

With a nod, Daniel held his father close, smiling within his neck. Nathaniel planted a small kiss on his son's forehead as he rubbed his back. As much as he didn't want his son to let go, he pats his son's back, alerting him that it was time to go.

Daniel finally let go after a few seconds more, a wavering smile betraying his feelings "I'll make sure when I come back, you'll be proud to have me."

Nathaniel snickered at that poor man's joke, the was no need to do that at all, "I'm already proud of you," Nathaniel pressed his son's nose, making him stumble back a little "You, should go. The next flight out is in four hours. And it's a six-hour walk."

"Right," Daniel adjusted the bag over his shoulder, smiling as he turned to walk away. This is where my journey begins…

Nathaniel turned to look at Killua.

The boy understood the look he just received. It was a solemn, stern expression, a silent 'save him' being uttered without words. He nodded, taking Alluka's hand within his grasp. He smiled at how easy Nathaniel has made his life, convincing his son to chase down the woman Killua hoped to use to save their fallen friendship, their relationship he wants to cherish once more.

If Zakaria won't do it, he'll find someone who can. He has friends he can talk to, ones whom may know a person or two who can remove the Nen now afflicting Daniel.

To Killua, this was first of many steps he had to take to save Daniel.

"~"

Killua relaxed his palm, resting it against Alluka's hair, flecks danced in his fingertips, flicking in all directions as he tried to contain the smile. It's been almost a week since he pulled her out of the mansion, a week where they could act like siblings, not children of assassins.

It was all thanks to Gon, and Daniel helping him achieve his goal.

Shifting his glance to Daniel, he saw the boy buried in his journal. It was the same one given to him, as well as Alluka by Vastorie. He cherished the gift, even though it served as a painful reminder.

I didn't imagine to think of you as a bookworm, Killua mused, a crooked slime now forming unconsciously. Although, it kinda suits Daniel, playing well with his drive to learn, even when it came to Killua, he showed that trait. Not so much the writing, but the learning aspect.

Alluka murmured in her sleep, moving to get in a more comfortable position as he allowed her, shifting his legs slightly so his knees don't rub against her chest. Once she stopped moving, his hand returned to her hair, curling some strands.

"Hey, Killua?"

Killua hushed the boy before responding, playing well on his overprotective nature of his sister, even though in a heartbeat, he'd never do that just to hear Daniel speak to him, allowing his affection for the boy rules his words. "Keep your voice low, I don't want to wake my sister."

"I have a question…" flick a few pages back, the boy flipped his journal, showing a single blank page, "what you think of this idea?"

Killua raised an eyebrow, huh, still the joker I see… "Sounds like a great idea, blank…"

Daniel turned the book back, frowning slightly "Oh, didn't expect you to be a non-Nen user…"

"No, I knew to use Gyo, I did so, but you wrote nothing down. Did you use In on that page?"

Daniel flicked a few pages back, continuing to write "Yeah, I must have…" If Killua couldn't read the page, it's possible he wrote it with the intention of using In, which seemed ridiculous, why would he commit to writing these feelings of love, for a guy he can't even remember? It was so strange…

Unless Killua was lying…

No, not possible. He would have a reaction because what was written down was by its definition, cheesy, embarrassing.

Killua's eyebrows furrowed, what exactly was on that page? What exactly did he say to make him slightly angry? "If you're upset at what I said, Alluka got one, no, two, one for me as well. Don't know what I'm going to write in my journal though…"

Daniel flicked a few pages forward, stopping at a particular page, a piece of information revolving around an Emitter technique he wished to substitute in his attacks. It detailed a process of extending one's aura to reach out like anacondas, increasing range without the need to detach the aura upon use. It would work well with his technique, the only problem is he'll need to refine it, to work with his Shadows.

"I was thinking…" Daniel hummed, flipped the journal once more, "as one Nen user to another, what you think of this?"

Killua rubbed at his chin, looking over the notes. It was mixed and matched, some spots blanked out, being cut from the final documentation. It might have been able to be read only by Daniel at this point. But this could be a test as well, checking to see how much Killua actually knows about him "Is it wise to show me something like that? Going by the details, I say you prefer long ranged Emitter attacks? Are you an Enhancer hoping to increase range, or an Emitter hoping to improve?"

"Neither…" Daniel remarked, twisting the book around, hiding his features behind the book with a frown "I guess Alluka keeps secrets from you."

"A girls gotta have her secrets," Killua mused with light laughter.

Daniel found himself smiling, cheeks tinting lightly, that laugh was sweet, sincere. Doesn't sound like Killua is the judgemental type, which is a nice edition. It kinda sucks he was treated like shit though, but he got out early, so that's a plus.

Thinking about the situation now, Killua went with the joke about dating, but considering his personality, he wondered about something "So, I was wondering… are you seeing someone?"

Killua frowned slightly, why bring that up? Was he trying to make small talk? This isn't a topic he wants to touch right now. Allowing a lip to curl upward, the boy joked, "Why, falling for my charm?"

"No, just curious thanks to the joke you set up with Nathan…"

"It's…" Killua dropped his head, bangs hiding his expression, "complicated…"

Looking over the book, Daniel found himself dropping the journal, curious as to why those words were full of sorrow. Why would Killua remain with someone who's hurting him? "Guy or girl…?"

"Guy…"

"He's a dick…" Daniel hummed, returning to his journal to continue working. "You should dump him…"

Killua felt his heart shatter at those words. If only Daniel could see through the veil, the lies contorting his memories. It wasn't that easy, to dump him… especially when he had a chance. But at the same time, he couldn't say shit, not when Daniel was so close to him. He didn't want to spark the boy's questioning gaze so he kept quiet, ignoring the remark entirely.

Daniel closed his eyes at the lack of words, Killua must be in a difficult situation, so there was no point continuing at all with this topic. "Alright, let's change the topic, what do you like to do in your spare time, if you had any?"

"Gaming, you?"

"~"

"Alright," Killua dropped his bag next to the wall, a small thud echoing around the room as he glossed over the surroundings. Soft deep blue carpet, diamonds-shapes patterned through the floor, leading up to the four main rooms. It was reasonably sized. There was an open kitchen, next to the smaller room, a single bed contained within, with a semi-walk-in wardrobe.

Killua navigated the rooms, checking to see what they had. The living room was the main entrance, connecting to the four separate areas. It contained a medium sized TV with a comfy couch across it, a dining room prepared to at least sit four people. Next to it was the toilet with a large shower for at least two people to fit, a nice addition for those who wanted to have a little space in the shower.

And the room next to that was the second bedroom, a queen-size bed filled the room with a reasonably sized walk-in-wardrobe, more space to navigate unlike the one with the single bed.

Taking a walk into the kitchen, Killua scoured it to see what they had. A large bench to work on and nicely spaced fridge. Cupboards contained all the utensils, glasses, plates, pots, pans as well as cooking gear needed to work with. He knows Daniel can't cook, but it's better to ask than to act like he knows.

Killua shifted his feet, standing up straight, "so besides there being only two rooms, can you cook Daniel?"

"Does food poisoning count?"

"I take that as a no…" Killua shifted his weight, holding a finger out to Alluka "Alright, you get the queen bed, and…" Killua flicked his finger out to Daniel "You and I flip on the single bed."

Alluka fumed, wanting to at least push her brother and Daniel to at least get to know each other, rebuilding the foundation of what was once was lost. Daniel and Killua sounded like they were starting to get along, becoming more comfortable with each other. "Why don't I get the single bed, and you two share the queen bed?"

The statement made Killua cross his arms, giving his sister a knowing glance. Without words, he wanted to alert her that was a bad suggestion. But she stood her ground, taking his lack of words on.

Neither of siblings relented. Daniel just had to address the situation. No matter who it was, he doesn't want to be hooked up with anyone right now, no matter how sweet and kind they are. It was wrong, unjustified to have his partnerships planned out by those he cares about, especially when the one whose being hooked with him, already has a partner of his own, "Alluka, I don't think your brother's partner would like that…"

Alluka's eyes widened slightly, now staring at her brother. He gave a hand gesture to roll with it, to not question the situation further. She frowned, turning her head away in annoyance.

Daniel sighed, flicking a hand out "If you want neither of us to sleep on the couch, Alluka… Why don't you and Killua take the queen, and I'll take the single?"

Killua ran his fingers through his hair, a little annoyed now. He can't deny that he wouldn't mind the company, but it just feels wrong in his heart, wishing he could instead share the bed with Daniel. The boy sighed "we'll stick to the original room layout. Heads or tails?"

"Tails!"

Killua flicked a coin, catching it to place it on his palm, once removed, Killua flicked the coin up once more "Tails, you win." It was a lie, wanting to instead take the couch. It's not like Daniel could read through Killua's lies anymore, as much as it pained him. He just wanted to be alone tonight, eyes glued the TV until he fell asleep.

Something about the mindless droning of characters and news seemed comforting right now, getting the edge off Daniel and his own talk out of his head. They spoke to one another if it's the first time they met, Killua having forced to repeat himself like a broken record as Daniel told him stuff he already knew.

Hopefully, he doesn't mix up what Daniel has told him on the flight here, with what he has learned during their relationship.

"Alright, so after tonight, we'll spend a little bit of time tomorrow to find a place that has three rooms?"

"Nah, I like it here. We're close to the shops, a nice-size kitchen and bathroom. Can't complain."

"Alright, so we'll ask tomorrow if there are any vacancies with three beds here, I guess then…"

"Sure, or we can ask them to switch out the queen for two singles. Either way, I like it here. Also, we need to at least gather some information on resorts and landmarks to show Alluka, as well as make a call to your sister tomorrow."

"Great, I'll deal with my sister… as you deal with, locations to visit… for your sister." The boy smiled, fingers swiping at his bag, dragging it into his room for the night. Honestly, he didn't understand why they couldn't look around a bit to see if they could find a place that did have three rooms.

Sure, it was pretty late into the night, but it couldn't hurt to look around.

Killua looked at the fridge, swiping the order-in-menu. It was too late to go out gallivanting with Alluka, but he rather not let her suffer from starvation either "I'm getting takeout, any complaints?"

"No tomatoes…"

"Alright…" Killua hummed, looking over the menu as he walked to help his sister out "let's get you to your room."

Helping her carry her stuff into the room, Alluka locked the door to release some frustrations onto her brother "Why didn't you disagree with Daniel."

Killua broke down, kneeling before his sister, she can't keep pushing this! It's not only hard on him, but one wrong move with Daniel could mean the end of their chance, "Listen, Alluka, there's no band-aid to slap onto this wound. Please, stop fighting with Daniel, just in case the situation worsens. I'll look into other avenues just in case Zaikaria doesn't go through. It might be rocky at the start once Daniel gets his memories back, but once things settle down, we'll be ok, ok?"

Alluka held her brother close, hugging him tightly into her chest. She just wanted them to go back to the way they were. She no longer wanted to see Killua's pained expressions. Maybe a couple of nights in bed with Killua could have jolted the boy's memories, making him remember about Killua, but it seems like that would be nothing more than wishful thinking. Why couldn't her brother just make the wish? Why couldn't he just ask Nanika to end all his suffering right now? "Big brother, why can't you just ask Nanika to help you…"

"Because… I don't want to use her for my own selfish needs, again. I… I want to help him in my own way…" Killua brought his hand to Alluka's cheek, smiling before resting his forehead against his sister. Honestly, he'd rather make that wish right now, but somehow, he'd feel cheated. Or worse… he may make a mistake.

What if Daniel learned he made a wish to revert his memories?

Will he hate him…? He wanted to believe he won't, but there was still that possibility. He was fickle right now, and the only way Daniel could ever accept those memories, as if he somehow, made the boy want to bring back those memories.

Hell, even making Zaikaria bring back those memories was a risk. She could instead remove all traces of Killua from his thoughts.

There was only one possibility he could get Daniel to accept those memories if he brought them back while retaining his new ones. The two will clash until Daniel eventually will choose to accept his new situation.

Killua knew deep down, that Daniel would choose Killua in the end during that situation. Because he has blank spots right now, unexplainable events. Hell, he wouldn't be able to come up with a situation where Alluka is even mentioned without Killua to fill in those gaps.

The only question now, was how…? How does make Daniel realise he has lost memories, unexplainable thoughts…? Is there no possible way?

Unless… there something he and Daniel did together, that nobody else knows about…? The dance on Greed Island! But bringing it up would be hard, maybe when they are alone, together just the two of them, he could do it. Perfect!

Killua removed his hand from his sister's cheek, pulling back so he could instead rest it on top of Alluka's head. "I think I know how to do it… I just need the right moment, so trust me, Alluka…"

Alluka's expression widened, glad to hear Killua thought of something. If her brother knew how to fix the predicament he was in, then she'll trust him. Hopefully, everything goes through well because, to her, her brother's happiness means everything to her.

"Alluka, how do you feel like going dancing?"
