"Onii-chan! Onii-chan! Can we go out again today? Please?" Alluka pleaded, pulling on her brother's arm.

Staring at Alluka's stubborn actions, a sweatdrop formed on the side of Killua's head. "Going outside too much is too risky, and we don't even need to get anything," he said, staying rooted to his spot despite her efforts to drag him.

"Ehhhh, but I still wanna look around! Come on, Onii-chan!" Alluka gazed up at him with big, puppy eyes, trying to get him to move.

Meanwhile, you could only stare at them from the sidelines, words refusing to come out from your mouth. 'I-Is this what Alluka meant yesterday...?' You thought, a sweatdrop appearing on your head as well.

Stepping forward, you were about to intervene when Alluka shot you an expectant look. 'Onee-chan, help me here!' you could almost hear her say.

'...Ah, I see how it is,' you thought, giving her a subtle smile, before turning to Killua. "Just let her go, Killua. We can come along and watch over her. Plus, we should be fine as long as we stay in crowded places, right?" Walking closer to him, you placed a hand on his shoulder.

With a beaming smile, Alluka turned back to Killua. "See? Even Onee-chan agrees! Let's go. Let's go!!" she exclaimed, eyes sparkling with hope.

Ignoring her, Killua whipped his head to face you. "Oi, I know I said that, but we can't be too reckless here–"

"Aaaand that's why we have our phones, right? In case we get separated, and something happens, we can just call you, so it should be fine!" you give a reassuring smile, trying to convince him.

With a frown, Killua stays silent for a bit, as if in deep thought.

"Killua... we're not powerless anymore. We can fight! So stop worrying too much about us, especially Alluka!" you grab his other shoulder, making him face you entirely.

His deep blue eyes, clouded with uncertainty, suddenly met your confident ones. A subtle heat rushed to his cheeks as he stared at your bright orbs. After a while, he finally let out a long sigh. "Fine, fine. Geez..." he mumbles, averting his gaze from you. "You better thank (Y/N)'s hard-headedness for this, Alluka."

"YAY!! Thanks, Onee-chan! And thank you, thank you, thank you, Onii-chan!" she squeals in delight, jumping over to give Killua a soul-crushing hug.

"You better not make me regret this," he says, patting Alluka on the head before she ran off to get ready. "Especially, you, (Y/N)," he narrows his eyes suspiciously at you, raising a hand to poke your forehead with his finger.

"U-Uh..." you start sweating nervously, feeling Killua's slightly deadly tone. Letting go of his shoulders, you wave your hands around in an attempt to reassure him. "Like I said, Alluka's much stronger now. You shouldn't worry too much!"

"You better be right about this," Killua sighs once more, staring at the doorway where Alluka ran off. "Anyways, we better go get ready as well."

You nod, before proceeding ahead. 'Alluka, you better know what you're doing. You're making Killua worry even more by doing this.'

_ _ _

"So then, what did you wanna do?" Killua asks, clasping Alluka's hand in a firm grip.

As the three of you strolled around the crowded shopping district, Alluka eagerly pointed to a huge store selling plushies and stuffed animals. "There! Can we go there, Onii-chan?"

"Yeah, yeah. Sure." Killua smiles, leading her to the store while you followed along.

In a rush of happiness and excitement, Alluka rushed ahead to the deepest parts of the store as soon as you stepped in.

"Oi, Alluka! Wait for us!" Killua exclaimed in a slight panic, though his voice was slightly drowned out by the crowd. With an irritated "Tch," he ran ahead to catch up to her.

A long sigh escaped your lips. 'Seriously, what is Alluka planning??' you frowned, watching Killua's figure disappear into the depths of the store.

'Not to mention, there's a lot of people here...' You look around in awe. 'Spotting them among this crowd is gonna take a while, especially since Killua covers his hair,' you thought to yourself, remembering the cap Killua wears.

"Well, I better catch up to them, at least," you sighed once more, running ahead to where Killua and Alluka went.

A short while later, you found Killua among the teddy bears, looking around in a panic.

"Killua? What's wrong? Where's Alluka?" you asked, as a small lump of fear started forming in your throat.

"I can't... I can't find her. I couldn't even sense her aura!"

You stopped in your tracks. "W-What? But she just ran here. She couldn't have gotten anywhere else!"

"That's what I thought, too. She has to be here! Which means..." he paused, frowning in confusion.

As you looked at his troubled form, your eyes widened in realization. "Which means... she's using Zetsu to hide from us, right?"

He nods slowly. "If something else happened, I would've known right away. This could be the only reason," he states. "But why would she do this?" he mumbled to himself, reaching for his phone to contact her.

'So, she thought that by hiding away, this could give me time with Killua? Geez, Alluka,' you sighed deeply. "Hey, Killua. I think I might know wh–"

Before you could finish, Killua's phone started ringing.

With lightning speed, he checked his phone. "It's Alluka!" he exclaimed, answering the call as a vein popped on his forehead.

"ALLUKA! Where the hell are you?!" he practically screamed on the phone, as everything else went silent around him.

Slowly, you could feel the stares of other people around you. "Uh... Killua? People are watching us–"

"Shh. Ignore them," he waves a hand dismissively.

You slumped your shoulders as a sweatdrop appeared on your forehead. 'This was not a good idea.'

Meanwhile, Alluka was giggling at Killua's irritation. "Hi, Onii-chan!"

"Don't just 'hi' me! Where are you?!" Killua exclaimed on the phone as the irk mark grew bigger.

Alluka clutched her stomach with her arm, trying to hold back laughter. "I'm gonna go look around on my own, Onii-chan! I'll return home by sundown," she smiles mischievously. "You should spend time with Onee-chan until then, okay?"

"HUHHH?! What do you mean on your own?! Do you know how dangerous that is?!"

"Onii-chan!" Alluka yelled through the phone, silencing Killua's complaints. "If you don't let me go, I'll be really mad at you!" she pouts, her brows furrowing.

"W-Wha–"

"Okay? Okay! Until I come back, spend time with Onee-chan!" she cheers, grinning from ear to ear.

"With (Y/N)?" He meets your gaze through the corner of his eye. "B-But–"

"No buts, Onii-chan! I'm strong enough to handle myself, so stop worrying so much!"

He sighs. 'That's exactly what (Y/N) would say...'

Alluka smiled, returning to her usual, cheery self. "I'll see you soon, Onii-chan! Bye!!"

And with that, she hung up.

Killua put down his phone, scratching the back of his head in irritation. "Geez, what is she thinking?!"

"Why? What did she say?" you ask, stepping closer to him.

He glanced at you briefly. "She said she's gonna look around on her own, and that I should be spending time... with you," he says, as heat slowly rushed to his cheeks.

"H-Huh?" Your eyes widened, as if you were at a loss for words. "What?!" you exclaimed, turning away from him just before he could see your cheeks turn tomato red. 'Alluka, why did you word it like THAT? I just wanted to talk to him!' you mentally screamed, half-hoping Alluka would hear you.

"A-Anyways, what else did she say?" you asked, calming yourself down and facing him.

He sighs in irritation. "She said I better let her go or else she's gonna be mad at me... Damn it!" he says, as faint sparks of electricity surround his body.

'Huh... it's been a while since I saw his Nen. I wonder why he chose electricity? Isn't it painful?' you thought, a small frown making its way to your face.

However, as quickly as it came, you replaced it with a small smirk. "Yikes, that's something I never wanna see."

"Yeah, yeah. Anyways, let's get out of here so Alluka can have her alone time, god I swear..." he mumbles, grabbing your hand and dragging you out of the store.

'Something tells me she actually wanted to be on her own... there are way better methods of getting Killua and me alone so we could talk.' you sighed. 'But thanks, Alluka. I owe you one.'
