Disclamer: All Katekyo Hitman Reborn! Characters here are not mine, I do not own them merely use them to make a story as all fan-fictions do. Any character that was not introduced to the anime ARE mine. This follows up after the defeat of the Millefiore Family at the time of the anime not the manga. Please enjoy! R&R!

Tsuna hugged his mom. "Mom…it's okay now." He looked at the girl and remembered about the time he got lost.

"Wahhh! Mama! Mama!" four year old Tsuna cried as he tried to find his mom.

"Tsu-kun! Tsu-kun where are you?" Nana looked around franticly. They had gone out for grocery shopping when they got separated as they entered a crowded street early evening.

Tsuna looked around for his mom but he couldn't find her, by this time the sky had gone dork and the streets were empty and lonely.

"Mama! Mama where did you go! Don't leave me!" Tsuna bumped into a huge dog. The dog growled and barked at him, making Tsuna even more scared, running away from the dog.

The dog ran after him chasing him around the streets until it cornered Tsuna in a dead end.

"Mama help! Mama!" Tsuna held his head between his legs and shouted. "Papa!" right after he shouted he heard the dog yelp and saw it run away.

Iemitsu walked to Tsuna picking up the small little boy and took him back home where he told Nana to stay as he looked around for his son.

The girl laid fast asleep for the rest of the day and was still asleep as Tsuna went back to school. As Tsuna walked to school Gokudera and later Yamamoto joined up with him.

"Good morning Jyuudaime!"

"Yes good morning Tsuna."

"Good morning Gokudera-kun, Yamamoto."

"Everything seems to be back to normal Tsuna."

Tsuna nodded and looked up. Something doesn't feel right… he thought to himself.

"Were you able to get anything out of the girl Jyuudaime?"

He shook his head and looked at Gokudera. "No, something is really bothering me." He ruffled his own hair frustrated. "How is it possible!"

The two boys stopped and looked at each other, then looked at Tsuna. "What is?"

Tsuna stopped and sighed. "Well…yesterday Fuuta tried to get rankings for her but he said that he couldn't pick up anything…then I still don't get why she was attacked by that guy and…" he looked at his hands. "When…when I was in my Hyper Mode…when…we touched I got shocked…but not when I'm normal."

Gokudera pondered for a moment while Yamamoto placed a hand on Tsuna's shoulder "Maybe it's mere coincidence. Don't worry about it Tsuna!" he laughed cheerfully.

"You think so?"

Yamamoto nodded and gave him a big grin. "Right Gokudera?"

Gokudera actually agreed. "Besides wasn't it raining yesterday? Reborn said that Fuuta's rankings get messed up because of it."

"R-right." Tsuna remembered the day before Reborn had gotten mad at him. He looked down at his feet as they arrived to their school.

The girl had just woken up when she saw Reborn looming over her. "G-good morning Reborn." She sat up on Tsuna's bed and rubbed her eyes.

"Who are you and why are you here." Reborn said plainly.

"W-what…?" she held something near her chest and looked down.

"You were the one who sent that letter correct?" He looked at her actions and frowned slightly.

Her hand tightened at her chest for a moment then she looked at him and nodded slowly. "Yes…it was a letter of warning."

"What about the drawing of Na-Tsu?"

She tilted her head not understanding. "Na-Tsu? What do you mean?"

Reborn took the envelope out and showed her the small print of what looked like Na-Tsu. "This…"

She looked at the drawing. "It's a kitten, I drew it like the kitty I have back home. Her name is snowball." She smiled.

Reborn looked at the drawing and she was right it looked more like a regular cat than Na-Tsu. "What the…"

She looked at him. "Is something wrong Reborn?"

He shook his head and looked at her. "So now answer my first questions; who are you and why are you here."

She placed her forehead on the bed as she bowed. "My name is Nako, and I come to stop the Foresta Family from eliminating the future Vongola boss, Vongola Decimo, Sawada Tsunayoshi." She paused then continued. "Reborn may I ask for a favor?"

Reborn sat in front of her and nodded. "Yes what is it?"

Tsuna tried to concentrate on his math homework but seemed to be having more trouble than usual.

Gokudera looked over to him and decided to help him out while the teacher stepped out. "Jyuudaime are you having trouble?"

Tsuna nodded and sighed. "It's really hard I don't get it at all." He slumped over his desk feeling depressed.

Gokudera put his glasses on and smiled. "I'll help you then!"

Tsuna slumped even more. "N-no…it's okay…" I'll get more confused if you try to teach me how to do the work Gokudera-kun. "I-I think I have it…it's okay." He worked on it again or at least tried to look like he could do it.

Soon it was lunch time and they all went to lunch.

On the way to lunch Reborn popped out from a fire extinguisher cabin that he had rigged so that it became one of his many secret hiding places. "Oi Tsuna!" he jumped on his large head.

"R-Reborn? Where were you?"

"Around, after school you are going to start training again."

"EEEEH? Why do I have to?" Tsuna complained.

Reborn hit him with Leon, who had transformed into a green mallet, then jumped off as Tsuna held his head in pain. "You've been slacking off and with the Foresta Family out there they could target at any time. With you not ready the next fight could very well be your last."

"I want to start training too Reborn!" Gokudera stood straight like a soldier.

Yamamoto laughed. "It could be good to keep the swing; I've been slacking off too."

Reborn smiled. "Alright then seems like its 2 to 1 so this weekend we will start training again whether you like it or not Tsuna!"

Tsuna slumped over and nodded slowly. "Oh! Reborn! Any news on who sent the letter?"

Reborn jumped and landed on Tsuna's head. "It's nothing you need to concern yourself about. I already took care of it."

"Uwah! Nana-san this is really good food! It makes my tummy so happy!" Nako exclaimed excitedly as she ate food Nana had made for her.

At this time she had regained enough strength for her to walk downstairs and eat at the kitchen table. Since her clothes were tattered and un-wearable, she was wearing some of Tsuna's old clothes that fit her about right. It consisted of a long sleeve buttoned up white shirt and brown shorts.

"Mama's food really is the best right?" Fuuta said with a wide and happy smile.

Nako nodded and continued eating. After she finished she went up to the sink and washed her plates as a gesture of gratitude. "Oh I almost forgot to introduce myself." she said as she rolled down her sleeves. She bowed at Nana and Fuuta, who were the only ones at the kitchen at that time. "My name is Nako; it's a pleasure to meet you."

Nana smiled. "What a really unique name!"

Nako smiled and giggled. "Yep!"

"Nako lets go play outside!" Fuuta took her hand.

Nako nodded happily. "Okay!" the two ran outside to where I-Pin and Lambo were playing and joined them.

After school ended Reborn and Tsuna went straight home finding them, Lambo, I-Pin, Fuuta and Nako, running around the yard playing tag.

"Sawada-sama you're it!" Nako said as she tackled him down giggling.

"w-what's….going on…?"

Nako got off him and smiled. "Welcome home Reborn-san."

"I'm glad that you feel a lot better Nako."

Tsuna sat up and rubbed his head. "N-Nako…?"

"Oh my name is Nako, Sawada-sama." She bowed at him.

Tsuna smiled and rubbed the back of his head. "I guess we never got to a proper introduction right? It's nice to meet you Nako, I'm Sawada Tsunayoshi." He bowed at her.

"I know your name already Sawada-sama…Vongola Decimo."

"Oi Tsuna! Time for your training to start." Reborn said as Nako picked him up.

She nodded and smiled. "It should be fun training with you Sawada-sama."

"E-Eh? What is she talking about Reborn?"

"She's going to be training with and against you."

"E-EEEEEH!"

Gokudera and Yamamoto came to Tsuna's house after they had gotten some things from their homes. Tsuna, Gokudera, Yamamoto, Reborn and Nako were all sitting around Tsuna's room.

"It's nice to meet you Nako-chan."

"Same here Nako."

"So what did you mean about Nako training with me Reborn?"

Nako looked at Tsuna and smiled. "May I answer this Reborn-san?"

Reborn nodded as he sat on Tsuna's head.

"Sawada-sama-"

"Please call me Tsuna…Sawada-sama sounds so formal." He smiled.

Nako giggled and nodded. "T-Tsuna-san…I'm the only one that has information about the Foresta Family, so I can help you get stronger...and I need to get stronger myself. I don't know…when they will come back." As she said the last thing she eyes fell down to her lap where her hands had formed fists and were shaking slightly.

"Well no one really knows when they will come back to attack." Yamamoto said with a smile.

Nako nodded and looked up. "That's why…I have to become stronger…I-I mean…we all need to become stronger…especially you Tsuna-san." He looked at him with her light honey colored eyes.
