Prologue

Sawada Tsunayoshi was seven when he made his first friend.

Tsuna had never had friends before that. He always played by himself and tried to avoid attracting any type of attention of those he knew would be more than happy to bully him. Although he didn't like what they did to him and how he was treated by both children and adults, Tsuna couldn't find it in himself to make them stop because he was, after all, only Dame-Tsuna.

He was useless and a failure and everyone knew that. Even his mother sometimes called him that. He knew she was teasing, but it hurts because she was his mother. Shouldn't she support him? Shouldn't she try to motivate him to do better or find something that he was good at?

Anyway, Tsuna was playing in one of the playgrounds next to his house that day. Too focused on the sand castle he was making, Tsuna never noticed the group of older children approaching him until one of them - the leader - stepped on his castle, destroying all his work and bringing tears to the corner of his eyes.

"Look, it is Dame-Tsuna." One of the boys said, grinning while his friends laughed.

Tsuna lower his head as he tried to hold back his tears. That group was one of his most insistent bullies and it always brought them a great amount of pleasure to see him crying. Unconsciously, Tsuna grabbed his bunny, which he had left beside him, and hugged the plushy.

"Well, look at what we have here," The leader of the group said with a smirk as he shoved Tsuna back and made the fluffy haired boy fall. Before Tsuna could react, the bully took his bunny from him and held it by the ears. "What are you? A little girl?" The bully mocked. "Look at this thing!"

Tsuna's eyes widened when the bully started pushing the ears of the bunny. If he continued doing that, Tsuna was sure that the plushy his mother gave him would end losing its head.

"Do you want your little toy back, Dame-Tsuna?" The boy asked, his smirk grew when he saw the expression of horror on Tsuna's face.

"P-Please, give it back..."

The bully placed a hand near his left ear. "Huh? I didn't hear you."

"G-Give it back!" Tsuna said, a little louder this time.

But the bully ignored him. It seemed like he was enjoying the sight of Tuna's tears. "Say that again Dame-Tsuna?"

Angry tears started streaming from his eyes and the boys all laughed. Tsuna was ready to run from them and look for his mother so he could find some type of comfort and bath in her warm presence. He was ready to move when someone stepped behind him and he noticed that all bullies froze, as if they had seen a ghost or something similar.

"He said to give it back. So could you please do so?" Although the words spoken by a heavy accented voice were fairly polite, it was impossible to not notice the unspoken threat there.

Slowly, Tsuna turned to see a small and skinny boy standing with a calm expression. The boy was wearing a green hoodie, black pants, white running shoes and he had a strange necklace around his neck which was a circle inside a triangle and a line passing in the middle of the two. The boy had messy strawberry blonde hair and his eyes...

Tsuna gasped when he saw the boy's eyes and understood why the bullies had frozen in fear.

Looking at those electric green eyes was the same as looking at a lightning storm. And as the boy narrowed his eyes, they seemed to glow with power.

"S-Shut up, freak!" The bully glared, clenching his hold on the bunny with more fervor.

The strawberry blonde boy shot him a bored look before raising one of his hands. "The bunny, please."

"I won't give you the bunny, freak. I will do whatever I want! Do you know who I am?" The bully sneered and his friends grunted in agreement.

The green eyed boy shook his head, muttering to himself. "Merlin... It is like looking at Dudley and Malfoy love child." Out loud, the boy said, "Should I?"

The bully gritted his teeth and his face gained a dull shade of red.

The green eyed boy chuckled in amusement before his smile fell and he narrowed his eyes. The friends of the bully ran away like headless chickens when those unnatural green eyes landed on them while the bully gave a step gave.

"The bunny, brat. Please."

If possible, the bully's face got even redder, although he was trembling like a leaf, as he growled. Tsuna yelped as he watched the older boy tear his bunny before throwing the head on the sand and the body in a bush near them. The bully turned around and started running, screaming about how the freak would pay for not respecting him.

"Usagi-chan!" Tsuna sniffed as he grabbed the head of his little bunny. If possible, even the plushy seemed to be crying.

The head was gentle taken from his hands making Tsuna looked up only to see the strawberry blonde boy.

The boy, who was also holding the body of the bunny, had his lips pressed together before he looked at Tsuna. "Come with me, please."

"W-Why?"

The boy smiled. "I know someone who can do something about your little friend here."

Tsuna stared at the house in front of him with his jaw dropped and wide eyes.

The green eyed boy hadn't waited for an answer from him before he started walking in direction of the forest near the park. Although scared, the boy was still holding Usagi-chan and Tsuna wanted her back, so he followed the boy inside the forest. For some reason, although afraid, his whole body relaxed immediately when he approached the boy and Tsuna felt safe. As if part of him knew that the boy would protect him from anything.

He wasn't sure for how long the two of them walked between the trees of the forest, but it didn't too much time for them to reach a three floor western house. It wasn't too big nor was it too small. The place was perfect for a small family and the garden around it was beautiful. Tsuna could see several colorful flowers and some of them made him shake his head and blink his eyes several times. After all, it would be impossible for flowers to move on their own, right?

The boy chuckled when he noticed Tsuna staring at a flower that looked like it was wearing lipstick. "They are magical." Tsuna looked at him with such wide eyes that the boy laughed out loud. "Come on, little lion. Let's get your bunny to a doctor."

Tsuna hurried after the boy as he opened the house's door.

Inside was very cozy and comfortable. Tsuna noticed several portraits on the walls along pictures and paintings of a beautiful and old castle. He couldn't see the pictures well, but he did notice how most of them were of a black haired girl with a lightning bolt scar in her forehead and some of them were of the green eyed boy and people who appeared on the pictures with the girl.

Actually, there was a great similarity between the strawberry blonde boy and the black haired girl - who was already an adult woman in some of those pictures -, especially their eyes. He wondered if the boy was her son...?

"I am home." The boy said as he took his shoes and urged Tsuna to do the same.

There was a moment of silence before someone finally answered.

"Welcome home, Haruka..."

A fairy... Was Tsuna's first thought when he saw a blonde woman with silvery-blue eyes came down the stairs. She was wearing a blue summer dress and her hair was filled with beads. She also had blueberries earrings and a necklace identical to the one the boy used.

The boy - Haruka - nodded with a warm smile when she patted his head before turning her attention toward Tsuna whose eyes widened and he blushed.

"And who is this?"

"I-I am S-Sawada T-Tsunayoshi!" Tsuna practically yelled before bowing.

"I am Morino Tsuki. But you may call me Tsuki-bachan." The lady said, tilting her head with a dreamy look and a small smile. "It is nice to meet, Tsunayoshi-chan."

"Tsunayoshi-kun's bunny needs some help, Tsuki. Could you do something about it?" Haruka asked as he walked toward her.

Tsuki blinked as she was handed the bunny. She hummed with a hand cupping her face and nodded.

"I will be right back." She said, turning around and walking down the corridor.

Tsuna frowned a little until the green eyed placed a hand over his shoulder, making him look at him.

"Don't worry, Tsuki will make him look like new."

Tsuna nodded before he looked at the floor. "T-Thank you for bringing me here so Usagi-chan could be repaired..."

Haruka patted his head. "It is nothing. After all, what are friends for?"

"Friends?" Tsuna's eyes widened. He couldn't believe what he was hearing. "We are friends? You want to be my friend?"

Haruka's eyes softened a little and he smiled. "Of course. Why not?"

Tsuna wanted to open his mouth and answer. Because he was useless. Because he did nothing right. Because no one wanted to be his friend. Because no one would want to be Haruka's friend if they saw him with Tsuna...

But he didn't say anything. Tsuna wanted to have a friends. He wanted to have Haruka as his friend.

"Y-You're really my friend?"

Haruka nodded. "I am. If you want me to be."

A blinding smile blossomed in Tsuna's face and the fluffy haired boy opened his mouth to speak when a male voice interrupted him.

"Hi ya, Haruka. Who is this?"

"Sawada Tsunayoshi-kun. I meet him today."

Tsuna turned to see a tall and strong man with dirty blonde hair walking in their direction. He had a kind smile in his face and warm honey eyes. He was wearing a simple white shirt, dark brown pants and had that same strange necklace around his neck. The man was holding a book in his hands and Tsuna noticed that it was about Japanese's herbs.

"Well, then... Hello, Sawada-kun." The man said.

He had the same heavy accent as Tsuki and Haruka. But while the green eyed boy's voice was calm and sweet to hear and Tsuki's voice held a dreamy and sing-song quality to it, this man's voice was gentler and quieter, almost shy.

The man smiled. "My name is Morino Hiroshi. I am Tsuki's husband. Have you meet her yet?"

Tsuna opened his mouth to answer but was interrupted again.

"He did." Tsuki said as she walked toward them.

She stopped in front of Tsuna and raised his bunny. He looked new. Not only the head was in its place again, but all those small imperfection that appeared along the years disappeared. The woman had also placed an orange bow around the bunny's neck.

"Here it is Tsunayoshi-chan."

"T-Thank you very much!" Tsuna bowed with grateful tears in his eyes and he hugged his bunny close.

Tsuki smiled. "I am glad to help, Tsunayoshi-chan. Just remember to come to visit Haruka, ok? He gets lonely when Hiroshi and I are not home."

Tsuna blinked and looked at Haruka who was now standing in a corner of the room with his arms folded. His new friend (And wasn't it a beautiful word?) was staring at Tsuki with a deadpanned expression but Tsuna ignored it and smiled innocently as he nodded toward the blonde woman.

"I promise!"

"Good!"

He looked at Usagi-chan. Tsuna would make sure that nothing would ever happen to his small bunny ever again, especially because now, it was the reason he met Haruka and the kind Morino couple.

"Tsunayoshi-kun?" He blinked and turned toward Haruka who smiled. "I asked if you want company to go home?"

"Y-Yes please!"

Sawada Nana knew that her beautiful son didn't have any friends. She saw how lonely he was and as much as she wanted, there was nothing she could do about it because no one could see just how wonderful her Tsu-kun was. They were all blind and looked at her son as if he was dirty. Even if Tsu-kun was a little clumsy and wasn't all that good in academics and sports, it didn't mean that he was stupid...

So when her son appeared one afternoon in their house with three foreign and one of them being a small child, Nana knew that nothing would be the same anymore and it felt like a weight had been lifted from her shoulders because as Tsu-kun introduced the little child, he introduced his friend, Haruka.

She immediately invited the three foreign to dinner and although they were ready to refuse her offer politely, but one look from her Tsu-kun made them accept.

Nana giggled.

She knew very well how dangerous those doe like eyes were so she wasn't too surprised by their reactions.

"You have a wonderful house." Tsuki said after Tsu-kun decided to show Haruka-kun his room.

Nana beamed at the blonde woman. "Oh, thank you!"

"Thank you for having us, Sawada-san. We hope we are not intruding." Hiroshi said, ruffling the back of his hair a little as he sat down next to his wife in the couch.

Nana shook her head. "No no, I am happy to have you all here. I am so glad Tsu-kun has finally brought a friend home."

Tsuki tilted her head with a warm smile. "Tsunayoshi-chan is a wonderful child. You did a great job, Sawada-san."

Nana blushed. "Oh, no... I did nothing, Tsu-kun is just like that." She blinked and leaned forward in her seat a little. "And you two are also blessed! Haruka-kun is a cute little thing."

Hiroshi shook his head. "Huraka isn't our child, Sawada-san."

Tsuki nodded a little sad. "He is the son of our deceased friend… Hari…"

She pointedly ignored the strange look her husband gave her. Nana didn't notice this as she placed a hand over her mouth and paled a little.

"I-I'm so sorry! I didn't mean to bring back sad memories!"

Before Hiroshi could answer, his wife shook a hand dismissively. "Don't worry about it! Unfortunately, Hari died at childbirth. She has been dead for seven years now. But I know that she will be always with us though." Nana nodded, although she was still feeling a little sad for having made this kind couple remember their deceased friend.

Again, Hiroshi shot her a look. This time, he was even mouthing her words in disbelief.

Before they could continue talking, there was a sound coming from the kitchen. Nana jumped, telling them that the soup was ready and as she walked out of the living room to prepared everything for dinner, she never heard Hiroshi's words to his wife.

"He? Harry is going to kill you, Luna."

His wife simply giggled.

Dinner was wonderful and Tsuna learned more about his new friend and his guardians.

Tsuki was a writer; she wrote children books full of magical and strange creatures. Tsuna had one of her books of his room and he was really surprised to learn that she was the one that wrote his favorite book. Hiroshi worked with plants and was a florist. He had opened a shop in the shopping district only a few weeks ago and invited Tsuna's mother to see it.

The Morino couple wasn't Haruka's biological parents nor were they related by any way (Hiroshi was Haruka distant – really distant – cousin). The couple had adopted Haruka after his mother died; the woman had been their best friend. They didn't talk about Haruka's father, but Tsuna and his mother also even didn't ask. Both had deduced that the man had left his wife and child behind.

Haruka, Tsuna learned, was born in July which made him older than Tsuna and the boy was clearly amused when Nana said that it made him Tsuna's older brother (Neither Tsuna or Nana noticed it when Haruka shot the Morino couple a unamused look at the word brother or how Hiroshi pointed to a smiling Tsuki, making sure that the other knew that it was all her fault).

He also learned that Haruka had a pet kitten - which he would introduce to Tsuna later - and his family was pretty big but all of them lived in England and had decided that they wanted to stay there, so only Haruka and the Morino couple had moved to Japan after his mother - Hari - death (Haruka really wanted to strangle Tsuki at those words, but only Hiroshi noticed the murderous glint in his eyes).

Tsuna was almost jumping from his seat when Tsuki said that she would enrolling Haruka in his school and maybe in the same class as him (If looks could kill, Tsuki would have been long dead because of the way Haruka was staring at her and if Hiroshi wasn't wrong, a revenge plan was already being made by the green eyed boy). It made him happy to know that he wasn't going to be alone in that hellhole anymore.

"Please, Tsuki-san, come to visit later! Maybe we could have some tea!" Tsuna heard his mother say as they walked to the door.

It time for the Morino couple and for Haruka go home. But as he stared at his new friend, Tsuna wished he could stay more.

"I will." Tsuki nodded, hugging his mother goodbye. "We can also have pudding!"

Hiroshi and Haruka snickered (There was an internal joke there).

"It was a pleasure to meet you, Nana-san." Hiroshi said, bowing.

"You too, Hiroshi-san!" Nana then turned to Haruka. "I would also love to see you again, Haruka-kun."

Haruka smiled and bowed. "I will come again, Nana-san. Thank you for inviting me." He turned his attention toward Tsuna who was pouting and sulking a little as he stared at the ground.

Haruka chuckled and patted the fluffy haired boy head.

"I will see you tomorrow, Tsunayoshi-kun."

Tsuna raised his head and beamed when he looked into those electric green eyes, a big grin forming in his face as he nodded.

"Yes!"

He couldn't wait for tomorrow!

Prologue

So, I was looking at some old stories that I wrote and found this. I rather liked the idea and everything that I had already written for this story so I decided to publish this. Especially since I am in love with the Reborn/FemHarry pairing because of Red String (Have you read it? No? You should).

Yes, Haruka is a girl and she is FemHarry. Hiroshi is Neville and Tsuki is Luna XD

This s only an introduction, but the reason why FemHarry was deaged and why she is living in Japan with Luna and Neville will be explained later on.

Anyway! I hope you liked this chapter and please, don't forget to:
