Prologue

"It's been a while, hasn't it?"

"Stop being so emotional."

"But it's true."

There was a party going on in the Vongola mansion. After a couple of years had passed, several new lives were being introduced. Greetings and reunions were being made, and tears and smiles were shown.

"Really, Hayato," Haru rolled her eyes at her husband. She was holding their five-year-old daughter, Mayu, in her arms. Their ten-year-old twins were standing beside her, peeking out from behind her dress. All three children had their father's silver hair, but while Yukine and Yukino had their father's emerald-green eyes, Mayu had their mother's coffee-brown eyes. "Stop being such a jerk to Yamamoto."

It was a miracle they were finally married. Probably because they were both equally stubborn, and would always argue to deny the fact they loved each other. They still argued, and their children had learned what to do when they have a long argument. The three kids would go make popcorn, put it into a big bowl, and settle down on the couch as they watch their parents argue. To them, it was the daily routine of an entertaining show.

"Che," the 10th Storm Guardian clicked his tongue at his wife, before turning back to the baseball idiot in front of him. "I'm not sorry."

Yamamoto laughed, used to these kind of things by now. He ushered his children from behind him. One was five-year-old Kazuto, and the other was ten-year-old Aoi. Both of the boys were the smaller version of their father.

"Why are you hiding?" Yukine peered at Aoi, raising an eyebrow.

"Ahaha, why are you hiding?" Aoi laughed.

"I'm not hiding! I'm observing the area," Yukine glared at the boy in front of him.

"Like anybody's going to believe that, big bro," Yukino rolled her eyes.

"Ever heard of closing your mouth, dear sister?"

"Ever heard of the word 'no', dear brother?"

The twins glared at each other, and one can literally see the lightning shooting from their eyes. Aoi continued to laugh at their "good" relationship. Finally, the twins got tired of the laughter and pretty much tackled the boy.

"EXTREME!" A shout was heard beyond the door of the room the party was supposed to be in. Not everybody had come yet, so they were waiting.

Gokudera inwardly groaned out loud at the voice, and Yamamoto laughed like he always does.

The floor flew open, and the 10th Sun Guardian stormed in. "HOW ARE YOU GUYS TO THE EXTREME!"

"Stop shouting, Ryohei!" Hana was standing beside him, sighing at the noise her husband was making. Their twelve-year-old daughter, Sayuri, and their six-year-old son, Shintaro, were laughing at their father's shouts.

"Stop shouting, lawn head! DID YOU EVEN GROW UP AT ALL?!" Gokudera shouted, glaring at the white-haired man.

"What are you talking about, Octopus-Head? Of course I've grown! TO THE EXTREME!" Ryohei shouted back, pumping his fists into the air.

"No, no he didn't," the others shook their heads, looking as if they pitied his simple mind.

"Keep making this ruckus and I'll bite you to death," a menacing aura came from behind them, and the three Guardians turned to look towards the door. An extremely irritated Hibari was standing there, along with Chrome and their children, and he didn't come to have a tea party.

"Kyoya," Chrome patted his arm, and his irritation only went down a little. Their eleven-year-old daughter Shiori was standing with their twelve-year-old son Tatsuya.

"Chrome!" Haru gave Mayu to Gokudera, quickly running up to the purple-haired woman. The two hugged, and a small smile came to Chrome's face.

"How have you been?" Haru asked, a smile on her lips.

"I've been doing well," Chrome nodded, her soft voice was always enough to relax anybody. It was probably the reason she got along with Hibari of all people in the first place.

"Are you okay? Did he do anything to you?" Haru's questions came out in a bundle. It took her a long time to accept the fact that her timid friend was married to the strongest and scariest Guardian of the 10th Vongola Family.

"Your wife is rude," Hibari stated bluntly to Gokudera.

"Che. I don't need you to tell me that," Gokudera set down Mayu so she could play with the other kids. "That woman's been rude to me for years." When Haru had heard this, she immediately glared at her husband. He returned her glare with a smirk.

"Our parents are really something," Tatsuya mused.

Sayuri laughed. "Really? I feel like they never became adults at all!"

"Shame, I had thought it would be all professional and mafia-like," Shiori shook her head in disappointment.

"..Why are we insulting our parents, again?" Tatsuya questioned.

"Because parents need kids to insult them to damage their egos," Mayu spoke up, and the older kids looked at the five-year-old in surprise. Mind you, Mayu is a very intelligent five-year-old.

"Ahahaha! I guess that's true!" Aoi laughed. "Your little sister's funny, Yukine!"

"Che. Of course she is," Yukine rolled his eyes, before ruffling his youngest sister's hair.

"Stop damaging my work on her hair, Yukine!" Yukino slapped her older twin brother's hand away.

"Will you stop hitting me!"

"You know, I feel bad for Mayu. She has to put up with two pairs of arguing people," Sayuri mused as she watched the twins argue once more.

"I don't particularly mind it," Mayu shrugged, sighing at how childish her older siblings were. "Because that's just who they are."

"Hey, hey! Have you guys heard of the stories about our parents' adventures?" Shintaro said excitedly. "I liked them to the EXTREME!"

"Ahaha! You're just like your dad!" Kazuto laughed out loud.

"Kufufu. I can see none of you people have changed at all," a mist surrounded the area, as the laugh was being heard. Several moments later, Mukuro stood standing at the doorway. He had a smug grin on his face, as usual.

"Mukuro-sama!" Chrome beamed with delight.

"Kufufu. How has the skylark been treating you, my dear Nagi?"

"Why do all of you herbivores think that? I'll bite you to death," Hibari glared at his arch-rival. His hand inched towards his tonfas.

"His head is a pineapple," Shiori stated out bluntly.

Mukuro flinched at the phrase. Chrome paled, "Shiori! Apologize!"

"But mom! His hair is seriously a pineapple! He could have passed off as a fruit!" Shiori protested, now pointing. Hibari was feeling quite proud of his daughter at this moment.

Mukuro regained his posture, looking a bit shaken at the moment. Was that little girl really his darling Nagi's child? No, wait. The little girl was definitely the skylark's child. The bastard was standing next to his daughter as he smirked victoriously.

He closed his eyes for a moment, before a smirk came into place. "Kufufu. So the skylark needed his own daughter to put out the insults now? Perhaps he's gotten weak."

The tonfas were out, and there was an aura surrounding Hibari so dangerous that it made the kids and even the adults inch away slowly. If there was anything Hibari disliked, it was being called weak. And they all seem to know, and understand that quite well.

"You guys sure like starting the party quickly," Lambo walked into the room, yawning a bit. He flinched when he saw the menacing aura of Hibari and Mukuro; their weapons in hand.

He slowly backed away, going off to another section of the room. That was what the others had done as they let the two Guardians fight. At the moment, they were feeling pretty bad for the repair people who had to fix the mansion afterwards.

I-pin came in moments after Lambo, holding the hand of their seven-year-old son, Notto. I-pin had gotten pregnant pretty early since the two had married after graduating college. With the extra lessons, they graduated pretty early.

"Why are they in bad terms, mom?" Tatsuya turned to his mother, who was watching the fight.

Chrome sighed, turning to look at her oldest child. "Mukuro-sama was the first person to defeat Kyoya. You know how your dad feels about the concept of, ah, losing."

Tatsuya nodded, knowing full well. Then again, his sister hated losing as much as their father did. Even he hated it at times. And their mother would always be the one to settle things down.

"So? Where's the Tenth?" Gokudera looked around.

Haru came up to him, wrapping her arms around his waist. "Kyoko told me they had to pick up some things before coming here, so they'll be a little late."

Yamamoto grinned. "That's just like Tsuna. Always late."

"Don't insult the Tenth, you baseball idiot!" Gokudera frowned. While he did snap out in a while and shout, he's learned to control his temper from time to time. Bianchi had commented how he's changed over the years due to love, and he had scoffed at that.

"Hayato, it's good to see you again." Speak of the devil. Bianchi entered the room, a smile plastered on her lips.

As soon as the silveret saw his older sister, he immediately felt sick to his stomach. "A-Aniki..!" He collapsed on the floor, and Yamamoto laughed as he carried his "best friend" to the couch.

Haru sighed as she watched her husband in his pathetic state. Really. One would have thought he would have overcome his trauma after so many years. But being the loving wife she was, she went over to his side and smoothed his silver hair out of his eyes.

"Auntie!" The three Gokudera kids ran up to their aunt, hugging her waist.

The pink-haired woman smiled in delight, picking up Mayu. "How has my favorite nieces and nephew been?"

"We're your only nieces and nephew," Mayu giggled. Bianchi laughed at that.

"Ooh, is the party already under way?" Dino grinned as he walked into the room, his kids behind him. One was fifteen-year-old Satoshi and the other was thirteen-year-old Ayami.

"Huh. I didn't expect you of all people to have kids," Hibari stated bluntly. He and Mukuro had called off a temporary truce after Chrome had gotten in the way of their battle.

Dino looked as if he had been stabbed. "Don't be so mean, Kyoya!" He grinned at his former student. "Have you been treating Chrome like a lady?"

Hibari snapped quickly this time, his tonfas out. "I'll bite you to death."

"W-Wait a second Kyoya! Now isn't the time to fight! C-Come on, we're here to have a friendly party, right?" Dino took a step back, and slipped on his own shoe. He fell on his face, and the others just laughed at the scene.

"Dad…" His children just sweat-drop, before going to help him. They, too, slipped on their shoes and fell on top of their father. God forbids them from inheriting their mother's good graces.

Hibari was questioning himself how this person ever became his tutor in the first place. He then decided to ignore him, and went back to his family.

"AH! Why is the mansion destroyed?!" A shout was heard from the door, and they turned to see who it was. There, standing at the door with his wife and daughters was the 10th Boss of the Vongola Family. After much hesitation, Tsuna had finally accepted his role as the 10th boss. You could pretty much guess how wild the party was when he had said 'yes'. Seriously, everybody was waiting for the moment to happen.

Kyoko giggled at her husband's shout and look of panic. While he had matured over the years, there were times when he would slip back to who he was in the past. She smiled down at their ten-year-old daughter Valentine, and their four-year-old twin girls, Mana and Ai. A brief sad smile came to her face as she looked at her children, before it quickly disappeared. There was no need to think about the past.

"Kyoko!" Haru smiled when she saw her best friend. The two cake lovers jumped up and down together, laughing. Chrome joined them, and the threesome talked about their lives and of course, cakes.

"Tenth!" Gokudera recovered quickly upon seeing his boss, and since Bianchi had put on some goggles, he wouldn't faint anymore.

"Yo Tsuna!" Yamamoto laughed as he went up to the two of them. "Been doing well?"

"Yeah," Tsuna smiled when he saw his friends. The Family had been split up due to, ah, some issues, but they kept contact over the years. He quickly remembered why he had shouted. "Why is the mansion damaged?"

"I'm sorry Tenth, but the crazy bastards decided to have World War III before you came," Gokudera informed him.

"A-Ah, Hibari and Mukuro again?" Tsuna sighed. "I really wish they would learn to get along."

Yamamoto laughed. "That's pretty much impossible considering it's those two!"

"They're selfish bastards with egos too big for their own good," Gokudera rolled his eyes.

"Dame-Tsuna, you're blocking the doorway!" Tsuna was kicked on to the floor as the hitman wearing a black suit and fedora strolled in.

"Ack! Tenth!" Gokudera checked to see if his boss was okay.

"R-Reborn!" Tsuna got up, after rubbing his sore back from the impact of the kick. "What kind of greeting was that?!"

Reborn smirked, and Tsuna quickly kept his mouth shut. That smirk was nothing but trouble. "I should get to kick you nine more times since it's been ten years since I last saw you."

"That doesn't make any sense!"

"You guys are twins? You look a lot alike," Kazuto grinned, looking at the twin girls in front of him.

"I'm Mana!" The twin with the longer hair introduced herself. "This is Ai." She gestured to her sister, who was hiding behind her.

Ai shyly looked at the people around them. "H-Hello."

Mayu smiled. "Not to worry, we don't bite."

Notto laughed goofily. "Hey, you guys are like opposites!"

Mana grinned. "We get told that often." Ai nodded in agreement. While Ai had inherited their father's lack of confidence, Mana had inherited their mother's carefree attitude.

"Wow! You like cakes too?" Yukino smiled widely at Valentine.

The light-brown haired girl smiled softly, but there was something about her smile that seemed calculated somehow. "You know about the new cake shop that opened downtown?"

"Yes! But I haven't gone there yet," Yukino confessed.

"Then we shall go together," Valentine suggested. The other girl nodded, and the two continued to chat, looking much like their mothers back then.

"Hey!" Yukine and Aoi joined the two girls. "You guys want to explore the place?"

Yukino nodded excitedly. "Sure! I wanna go!"

Valentine sunk back, looking at her parents. "Is it okay...?"

Aoi grinned. "Yeah! We're still gonna stay here for a while anyway!"

"As long as we stay here." Valentine nodded slowly.

"Great! Let's explore!"

"So many people," Satoshi grinned as he looked around.

Ayami laughed. "You see, Onii-sama, there were going to be a lot of people! It's a party after all!"

"We're going to party to the EXTREME!" Both Ryohei and his son Shintaro shouted at the same time. Hana and Sayuri could only smile at the boys.

The party lasted well into the night. After years of not seeing each other, they were determined to make the reunion a time to remember. Ever since that incident ten years ago, things had been complicated. But now they had decided that it was time to forget the past and move on. Thus leading to a couple of drunken people and shouting and fighting breaking out from everywhere. The shouts and hoots of chatter was heard loud and clear. It was lucky the mansion was located in the forest, or else they would have disturbed numerous neighbors.

"Tsuna." Reborn came up to the 10th boss as he stood on the balcony, over looking into the night sky.

Tsuna had come away from the lively party for several moments, feeling as if he needed a break. He turned to face his former tutor. "Reborn."

"You know how things are going to be from now on," Reborn informed him, his fedora shadowing his eyes.

Tsuna clenched his fist, before he let it relax. "Yes. I just don't want anything to happen like ten years ago."

"Then you will protect her. Protect her from the truth," Reborn stated seriously.

"Yeah…"
