March 28, 20XX,

It was nice sleeping under the stars. I remember when Tsubasa and I would camp out on our backyard, or roof occasionally, just to get closer to the sky. Oh memories, how I miss thee old days... Anyhow, the funny little girl, Tsukisa, will be meeting with me... Of dear, I realized I never asked when she will be meeting me. I was hoping to explore Namimori a little and check on Tsubasa, but I supposed I will have to delay that until Tsukisa comes.

Tsuna was swinging his legs like a child as he took a sip of hot cocoa he had bought from the cafe across the park. Taking a bite of the chocolate covered croissant, Tsuna decided to stare at the sky to keep his mind off the past. Until a high-pitched voice called for him and a small body landed on his lap.

"Oof!"

"Heehehe! Onii-San is here! Onii-San is here!"

"Tsukisa-chan!" Tsuna exclaimed in surprise. "You're here early, don't you have school today?"

The small brunette pouted. "Mou! It's Saturday silly! No school today!"

"Ah, I suppose that's true." Tsuna mused, realizing that today was Saturday. Lately he hasn't been able to focus lately for some reason as he usually do. But he just brushed it off as an off day... And he would regret ever ignoring his intuition that had been giving him warning signs ever since he arrived to Namimori. "Well then Tsukisa-Chan, what does a little girl like you want to talk to me for? Don't you have anything better to do?"

She shook her head. "Not really~ I'm just... Worried about you, Onii-San."

"Eh?"

"You look lonely..." Tsukisa said, frowning as she squinted her eyes at Tsuna, rather cutely in his opinion. If Tsuna was feeling a bit better, he would pinched the little girl's cheeks for being so gosh darn cute! "And you look sick... Onii-San, I think you should sleep."

Tsuna smiled, and ruffled her fluffy hair, earning him a protest as Tsukisa tried to swat his hands away with her smaller one. "You not need to worry about me little girl, I will be fine."

At this, the smaller brunette paused, then looked up at Tsuna with a calculating eye. Tsuna couldn't help but fidget under her gaze. It was strange... It was obvious this little girl was different from any other kids he'd ever met, but the way she looked at him as if analyzing him... It was unnerving that a kid, a little girl who was just 5 years old no less!, would look at him with eyes like that. As if she was trying to look into his soul.

This little girl... Could she be?

...

No.

Tsukisa was nothing but a civilian girl. There was no way she had any connections tot he underground. It wasn't possible that someone as sweet as Tsukisa could be...

"-An... Onii-San!"

"W-What?"

The girl pouted, crossing her arms as she huffed. "Onii-San isn't listening to me at all! You're so mean!"

"Hahaha, sorry about that Tsukisa, I was just thinking. What did you have in mind?"

Tsukisa gave him one last glance, before she smiled, showing off her baby teeth as she sparkled with flowers blooming behind her- Oh no.

"Onii-San," Tsukisa started, fluttering her eyes cutely as she made a pout, and somehow her eyes were larger than before. "Do you want to come over to my house tomorrow? Mama would be happy to have another guest! And I think Big Brother would like to meet you! I think Big Brother needs more friends, and I know you're perfect for it!"

"Oh- Um... I don't think I can-"

Cue tears pooling at the side of her large, brown eyes.

"O-Onii-Chan doesn't want to meet my family?"

'No, don't look into her eyes!' Tsuna screamed in his mind, desperately trying to look at anything but her. 'Why does she have to be so similar to Tsubasa?!'

And just like those times when Tsubasa would ask a request from Tsuna... It ended with Tsuna the loser.

As Tsukisa was practically sparkling by this point, the brunette pouted as he gloomily chewed on his now cold hot cocoa. This was so not fair...

But Tsuna wasn't able to wallow into his depression when small arms wrapped around his waist, and a small body cuddled onto his side. Looking down, he saw Tsukisa melding her small body onto his side, a content smile on her face.

"I'm happy Onii-San is coming to meet Big Brother and Mama."

The brunette glanced down at the small child cuddling to his side, and with a small smile on his own, he hugged her tighter. The two were engulfed by warmth that Tsuna hadn't felt in such a long time. It was so unfamiliar, and yet so familiar...

Tsuna wished he could stay like this forever.

Nana Sawada hummed happily, preparing dinner. As she covered the boiling soup, she smiled when she heard 'Taidama' from her youngest child.

"Okaeri Tsuki-Chan!"

Trotting in the kitchen, the 5-year old ran intot he kitchen and hugged her Mama tightly. Bending down a bit, Nana picked up Tsukisa and the two rubbed their noses together. The brunette giggled happily, and Nana noticed that her only daughter was happier then usual. This made Nana happy as well as she spun around the kitchen before placing Tsukisa on the counter, where she could watch her Mama cook.

"Did something good happen Tsuki-Chan?"

"Un Mama!" The brunette smiled. "I invited Onii-San over for dinner for tomorrow!"

"Really? That's great!" Nana said happily. "I'll make sure to set an extra plate for your friend tomorrow. Do you know what kind of food he likes?"

At this, Tsukisa thought about it. Then after a while, she answered, "Steak!"

"Really? Well it's a good thing I stocked up on steak today. Hm... I wonder how he likes it..."

As Nana wondered what Tsukisa's Onii-Chan was like, and how she should cook the steak, Tsukisa jumped down from the counter and was about to head to her room until the door opened, revealing a rather tired-looking blond.

"Taida-"

"Okeari Big Brother!"

Tsubasa grinned, catching Tsukisa mid-air before kissing her on the top of her head. "Tsuki-chan! How is my princess doing today?"

"I got Onii-San to come over for tomorrow for dinner!" Tsukisa chirped happily, but then blinked noticing how Tsubasa suddenly frowning. "B-Big Brother? Why are you frowning?"

"Tsukisa... Why do you call a stranger onii-san?"

At this, Tsukisa tilted her head as she thought about it.

It was true Tsukisa was rather shy around strangers, but when she met her Onii-Chan on the park, looking all sad about something even when he didn't show it, she walked right up to him and talked to him as if she was someone she knew. But he wasn't, yet Tsukisa had never felt so comfortable around others except for her Big Brother and Mama. There was just something about Onii-San that was important, as the small voice in her head say. The voice also said that if she didn't do anything, that would've been the last time she would see her Onii-San. Which was why she invited him over to dinner.

She really like her Onii-Chan. And she felt as if she found something that she never knew she lost.

"Because... Calling him Onii-San is right."

Tsubasa frowned, but then sighed. "Alright, I won't say anything."

Putting Tsukisa back down, Tsubasa was about to head back upstairs until small hands gripped onto his shirt. Looking down, she saw Tsukisa's brown, determined eyes, which eerily looks so much like his Onii-San at times, stare at his dark blue eyes. "I'm never going to replace Bigger Brother with Onii-San. You know that, right?"

Tsubasa stared at Tsukisa, then a small smile bloomed from him face as he hugged Tsukisa tightly. "I know Tsukisa. I know you won't ever replace you Bigger Brother with anyone else..."

The two siblings stayed like that for a while, before Tsubasa let go and ruffled her hair, making the smaller brunette huff at that action, before blinking at how familiar that was... Tsubasa didn't notice and smiled tiredly. "Anyway... I'm a bit tired. Gokudera-kun and Yamamoto-kun... Hibari-San... Chaos..."

Tsubasa was muttering about something as he went upstairs, but Tsukisa just ignored his Big Brother's rambling and headed to her room as well. Wondering what she should wear tomorrow when she was going to meet her Onii-San!

Tsuna scratched the back of his head, wondering how he got dragged into meeting Tsukisa's family.

...Right... She had to look a lot like Tsubasa... And act like him when he wanted something.

The brunette sighed again. Sitting on the same bench he had been sitting and sleeping on for the past few days, Tsuna only had to wait 20 minutes for before Tsukisa finally came, and the elder brunette couldn't help but raise a brow at what the little girl was wearing.

A cute frilly pink dress, pink shoes with bunny ears, her fluffy hair tied to two pig tails, a pair of bunny ears on her head, and she was armed with a bright smile and wide brown eyes full of innocence. All in all, Tsukisa was completely adorable, and Tsuna couldn't help but be amused when Tsukisa made a small twirl to show off her dress, and noticed the pink puff on the back of her dress.

Honestly, this child was too cute, and Tsuna had a feeling that when Tsukisa grew to a teen, she would be gorgeous. He had to feel bad for whoever her brothers were, they were going to have a hard time fighting off her suitors.

"Onii-San how do I look cute?"

"Like a fluffy bunny I just want to keep forever." Tsuna grinned, and stood up as he patted any imaginary dirt on his person. "Shall we go meet your family now?"

"Un! This way Onii-San!"

Tsuna smiled, though it was wiped off when he noticed the neighborhood he was. The brunette grew jumpy, and when he tried to release his hands from the little girl's, he was mildly surprise when the little girl tightened her grip. and kept his on hers. For a little girl she was strong...

"Onii-San we're almost there!"

"W-Wait Tsukisa... W-Where do you live"

Tsukisa looked up, then forward before she stopped in front of a certain house. She threw her arms wide, grinning happily as she opened the gate. "Tadaaa! This is where I live!"

"Y-You're a Sawada?!"

"Un!"

Tsuna was seriously on the verge of having a heart attack. He was surprised, but he was also so, so happy and so sad. Happy because that meant he had a little sister and now he can spoil someone else. And sad because that meant he had to leave her as well. One word can only describe this situation.

'Crap.'

Tsukisa has invited me to dinner today. I hope her family is okay that her friend is a lot older... Yeah, this may not end well, but it'll be nice to have real food for once. I still miss Mama's cooking. Anyhow, wish me luck tomorrow journal.
