Chapter 1

Iemitsu and Nana was a happily married couple that blessed with a pair of twin. The father of twin happily cradled on of his children and lovingly looked at his wife before kissed the dark brown haired woman. The birth process went calmly without any problem except for shouting, moaning and yelling here and there mainly from the wife. Iemitsu squeezed his free hand behind his back, relaxing it from Nana's death grip during the process.

Other family members from both Iemitsu and Nana side already left the room, gave a personal moment between the two newly parents.

"You're a wonderful wife and mother, dear," Iemitsu finally said after took another glance at their baby in his arm. And surprisingly strong too, I can't really feel my other hand right now.

"You too, dear. You're great father for our children," Nana replied and looked down at her arms where another baby was. She was nursing and her gaze softened when clashed with her husband.

Iemitsu smiled once again and looked thoughtfully at his wife. "So what their names will be?"

Nana looked at the hospital white ceiling before smiled cheerfully at her husband. "Didn't we decide about it already?"

Iemitsu grinned.

"Tsu-kun, Na-chan, wake up dear," Nana said while pulled the blanket from both kids. "It's time to wake up already both of you two."

A three year old girl slowly sat up while rubbing her eyes with her small hands. "Mom?" She pouted softly as Nana already kept the blanket away from them.

The young woman smiled and ruffled the brown hair before playfully pinched chubby cheek of her daughter making the latter squeaked and laughed. The noise made the three year old boy softly groaned before sat up.

"Mom? Natsu-chan?" The boy softly asked, making the two focused at him.

Nana did the same thing to her son and giggled. The sight in front of her was far beyond than adorable when her son pouted and at the same time smiled happily at her. Her daughter then tackled the sleepy son and both of them playfully snuggled on each other with laugh. The young woman sighed and stood up.

"Now, now both of you, the breakfast will ready soon and do a favor for me?" Nana smiled and pointed to the closed door near the children room.

Both of her children perked up at their mother request and eagerly nodded.

Iemitsu was drooling on one of pillows when their room door slowly opened. A few small footsteps could be heard while the room owner was still in his deep slumber.

"Nana~~" The blonde man called his lovely wife while hugging the same pillow he drooled on. Still in heavy sleep, the man didn't realize there were other occupants in their room, staring at his sleeping behavior.

Sawada Tsunayoshi, the eldest of the twin blinked at the sight in front of him before looked beside him. There, stood the youngest twin, Sawada Natsume who was shrugging herself.

"What should we do?" Tsunayoshi softly asked at his sister while the latter placed a hand under her chin.

"The last time we do this, we totally failed and I don't want that happened again." Natsume stared at the bed.

"I have a few suggestions."

"What is it?"

"Hi-Hit him with pillow?"

"We are just kid and the impact is just nothing to him, anything else?"

"What about jumping on the bed?"

Natsume grinned and looked at her brother. Tsunayoshi get the hint, quickly climbed on the bed before pulled his sister on the mattress. Both of the children looked at each other, chuckled and later both of them were stood up at the kitchen entrance with pouted face.

Nana chuckled softly while still rubbing her husband back, providing a comfortable feeling to the man as the latter was groaned sickly at their kitchen table. After a few moments, Iemitsu calmed down and looked at his children with stern gaze.

"Whose idea is that?" The father asked firmly made both of child flinched. The former quickly regretted at his action but retained his serious gaze.

"I-It w-was m-me," Tsunayoshi said softly, his eyes became glassy as tears started framing at corner of his eyes.

"N-No! It was me!" Natsume suddenly shouted made the boy looked at her.

"No! Me! I-It was my idea, really!" The boy shouted.

"No! Mine idea!"

"No it's not!"

"Yes it was!"

"No!"

"Yes!"

Tsunayoshi ready to shout once again but stopped when a pair of arms suddenly hugged him. A squeal was heard followed with a deep sigh. "It's our idea." A muffled voice said.

Iemitsu laughed softly before crouched in front of hugging twin. He pulled both of the children into his strong sturdy arms. "I'm sorry, was my acting really scared both of you?"

Both Tsunayoshi and Natsume looked at their father with doubtful gaze.

"You're not angry?" Natsume asked innocently.

"Er…"

"You're not angry and lying to us!" Tsunayoshi shouted but it quickly replaced with a shriek as the father scooped both of them and left the kitchen. Natsume tried to release herself but failed. They went back to their parent's room in their father arms.

"At least gives me a warning when both of you want to do that. I still dizzy," Iemitsu said and placed down both of his children on the bed. "Let's clean both of you while your mother preparing our breakfast."

Tsunayoshi looked at his sister and noticed a gleamed in the girl eyes. Natsume nodded and both of them jumped on the bed again and with happy shouts together. The father groaned and smirked before joining his children, ruining the bed.

Nana was preparing sunny side eggs when she heard a loud crash from their room.

"Oh dear," She said and after a few moments, she focused back on her work with a happy hum after heard hearty laugh came instead of crying.

Iemitsu occasionally left his family for a time range for his work (heh…) and came back with opened arms for hugs and kisses. Nana never doubted about her husband work and never questioned about it since her hands already full with the twin and housework. Nana was cleaning the kitchen after lunch while Iemitsu watched out for their children at living room. Natsume was reading a book for children while Tsunayoshi was playing with plastic blocks.

It was that time Iemitsu saw the relationship of his son and daughter and felt a familiar feeling came from it. The kids were four years old.

"Natsu-chan."

"Yes, Tsuna-niichan?"

"I want to build a c-castle but I don't know where to start."

The younger of the twin looked at the scattered plastic blocks on the floor. She then looked at her brother. "Let me think for a while Tsuna-niichan."

"It's okay, I will wait, Natsu-chan, d-don't rush."

"Thank you niichan."

After a while, Natsume calmly explained to her brother how to build a castle while Tsunayoshi nodded and followed the instruction. The eldest of the twin thanked his sister before focusing at the block again while the younger nodded and continued her reading.

Iemitsu stared at his daughter and shook his head. Why I'm seeing myself and Ninth in them?

The thought quickly disappeared when Nana approached them with a plate of sliced apples in it.

His children were five when the current Vongola boss came to Japan for a visit. After small accident including a ball, a Chihuahua, a deathly hug between the twin and two burning dying will flames, Timoteo decided to seal it with his power.

Iemitsu silently agreed with his boss and promised himself to keep his family away from their world until the right time came around. He even wished the day never came even though he knew that was a futile hope.

After the eventful day and the ninth left Japan, Natsume started to showed some interest in martial arts and the one picked her interest was karate. Tsunayoshi stayed beside his sister when the latter watched the tournament from their television.

"It's too brutal," The eldest of the twin said and shrugged.

"I don't think so, it looks cool." Natsume's eyes focused at the screen.

Iemitsu and Nana both decided to send their children for karate class after Natsume persuaded them about it while Tsunayoshi silently nodded, still unsure about it.

After a week, Tsunayoshi decided to leave the karate class.

Nana was preparing something for their dinner when she spotted a messy brown nest peeked up at kitchen door. Iemitsu was not at home and their daughter had the karate thing. She smiled when her gaze clashed with innocent brown orbs.

"Tsu-kun?"

"Mom?" Tsunayoshi stepped out from his hiding and entered the kitchen.

Nana eyed her son. "Do you need anything?"

The eldest of the twin already stopped beside her and looked at the preparation she made. "What are you doing?" He asked softly while his gaze focusing at colourful chopped veggies.

"Hm?" Nana blinked.

Tsunayoshi was a soft spoken boy while his sister was a quiet one. They just smiled and nodded when their teacher called their name and only a few kids were able to hear enough what the twin spoke so far. They were enrolled in Namimori kindergarten and when there were many friendly people around, there were also bullies.

Clumsiness of both twins didn't help much in avoiding the bully group but after some training from karate class she attended so far, Natsume managed to hold them away but sadly, both of them never escaped from insult of the bullies.

They were called no good twin and when they were alone, dame Tsuna and dame Natsu was heard among the children.

Bad turned to worse. The whole kindergarten called them with the nickname and their grade also didn't help any.

Iemitsu enjoyed the sun while observing his daughter performing some karate movement in their garden. His son was stayed with Nana at the kitchen and he sometimes wondered since when the eldest of the twin helped his wife with the food. His gaze focused at Natsume when he heard the girl shouted and jumped with a kick at the air.

The kids were at fourth grade in their elementary school. Iemitsu sighed.

"The time sure goes fast," He muttered softly.

"Yes, I missed them when they were babies," Nana chuckled and placed down a tray of orange juice. She had cut her hair from back length to neck length long but her appearance still remained beautiful and lovely.

Iemitsu couldn't ask more when he was stayed around with his sweet wife and cute kids.

"Where's Tsuna?"

Nana chuckled. "In the kitchen, he is preparing some dessert for dinner."

"He is a real helper in there." The father looked at the garden and looked at their daughter.

"Yes he is, Tsu-kun is my second in there," Nana happily said and sighed. "I wish Na-chan would develop some skill in that area too."

Iemitsu laughed. "You know what Nana? I wished the same too for our son."

The mother smiled. "I believe they will do fine later."

"I agree with you. Our children are the best."

"And I hope their clumsiness will lessen too. Sometime I really wonder how come Tsu-kun never got hurt while handling a knife and Na-chan gracefully performed in her karate while both of them always fell down from the stairs every morning. It seems the clumsiness is in the gene."

"…I don't know about that…" Iemitsu looked away. Damn genes!

Nana blinked innocently at sudden behavior from her husband.

Sawada Tsunayoshi and Sawada Natsume were walked to their school when their path was blocked by a group of bullies.

"Halted both of you, no-good twin," One of the bullies said made two of the fifth grader stopped their track.

"W-What d-do you w-want f-from us?" Tsuna stepped forward in attempt covering for his sister. He could feel that his legs shook madly and his stuttering worsen.

"Y-Yeah…what do you want?" Natsume asked when they got no respond from the bullies. She scanned the group and shuddered. The group was composed with middle school students and she knew that they didn't really have any chance to leave unscathed. Are the news about our nickname has come that far? Even middle school student know about it.

One of the bullies already picked up Tsuna by his collar and Natsume quickly shouted.

"Tsuna-niichan!"

"N-N-Natsu-chan…run!"

"No! I can't leave you behind!" Natsume quickly wiped her tears and placed down her bag on the ground. She stood in a stance. "Let Tsuna-niichan down or…"

"Or else what little girl?" The boy taunted but suddenly he gasped and released the grip on Tsuna's shirt.

Natsume planted a solid kick at the boy precious area.

Tsuna gaped at the sight as he landed on the ground harshly. He quickly stood up and ran to his sister. "Natsu-chan!"

"Tsuna-nii!"

They hugged each other but other bullies stepped forward.

"G-Get them!" The boy who was kicked groaned but suddenly no one of their gang moved. "Hey! What are you guys doing? Get them!"

"N-No can do…"

"Why?" The boy groaned and looked at the pointed hand. His face blanched. "H-H-Hi-Hibari-san!"

"For disrupting the peace of Namimori, I'll bite you to death." A raven haired boy stepped in front of hugging twin.

Natsume blinked and shuddered. Tsuna followed. The group of bullies was bitten to death in front of them.

Natsume sat down after done a few rounds of her training and after a few sips of orange juice prepared by her mother, someone sat down beside her. She looked at the newcomer and smiled.

"Dad, when you're back?" Natsume happily asked. Apparently, their father rarely stayed at home anymore due to the workload coming (Uh…huh…) and even he stayed, it just only few days instead of months like previous years.

Iemitsu smiled. "Just right now, Natsume. How's your training?"

"Good! There will be a tournament at our school and I'm participating in it." The girl happily explained.

"I'm sorry that I cannot see you in that event," Iemitsu said with a sad smile but the burden was lifted at her daughter next words.

"Uh huh…its okay dad, Tsuna-niichan will be there watching me and don't worry about it! I'm strong."

The blonde man nodded and patted his daughter head, ruffling the soft brown hair. Natsume chuckled at the affection she received. Even with different gender, both Natsume and Tsuna had similar appearance except for their hair. Natsume had tamed brown hair reaching her neck like her mother and Tsuna with his wild gravity defying nest but both of them had similar bangs. They could switch by changing the hair style and no one was able to detect which one was the real Natsume or Tsunayoshi. Even their parents were fooled with the change.

"Natsume," Iemitsu called made her daughter attention solely on him.

"Yes dad?" Natsume asked and blinked.

Tsuna harshly pushed both of his sister shoulders and quickly ran away from the place. Natsume, failing reaching her balance, fell down on the floor. Laugh escaped from a group of boys and they left the area.

Brown orbs stared at the way where her brother ran away and a tear fallen down.

Tsuna-niichan…do you really hate me that much?
