Chapter 1

It all started when Rena finally arrived at the Namimori Airport. She came from Italy to see her family. She gathered her luggage and headed out of the airport and caught up with a subordinate her father contacted. Rena entered the car while the subordinate had taken her baggage and placed it in the trunk of the car. After he was done, he starting driving towards her destination.

About an hour and a half later, they finally arrived in the front of the house. The subordinate opened the door for her and went to the trunk of the car to get her luggage. Rena had gathered her luggage and then walked to the front door then used the key to the door her father had lent to her. She inserted in key into the key hole and turned it then reached for the door knob and opened the door. It's been a long time since she seen the house. As she walked in, she left her bags by the front door and took off her shoes. Rena looked to see if anyone was home until she heard a familiar voice saying

"Tsu-kun, your father might be coming home soon" a feminine voice said.

Instantly Rena walked towards where the voice came from then shouted.

"I'M HOME!" running towards a brunette woman and hugging her.

"Rena-chan, you came early. It's been so long" The mother replied.

After Rena hugged her mother, she ran towards a brunette male that was in the room.

"Tsu-chan! I missed you." Rena said

The brunette boy was blushing that some girl was hugging him, but more confused into who was she and how did she know him and more importantly the fact she is calling him "Tsu-chan".

"Ummm….W-Who are you?" Tsuna asked

"Tsu-chan, you don't remember who I am, do you?" Rena asked pouting at Tsuna

"E-eto…" He thought for a moment, No" Tsuna responded

Rena took a deep breath then continued talking.

"I am your sister." Rena stated

Once Tsuna heard this he frozed and was confused.

"I-I have a sister?" Tsuna asked

"I guess it has been a while since you seen her Tsu-kun, why don't you show her around and get to know each other, while I prepare dinner." Nana said

"Uhhh... Okay." Tsuna replied in an unsure tone

Tsuna left the kitchen with Rena following behind him. He showed her around the house and had also taken her luggage and placed it in Tsuna's room. They then went back into the kitchen where Nana was. She was making dinner for later.

"I guess I'll show Rena around the town" Tsuna said to his mother

"Okay, don't stay out too late." Nana said

Tsuna and Rena then put on their shoes and left the house. They first stopped at the shopping area and strolled around. Then they passed by Namimori Middle School. Last but not least, they went into the park and sat on the swings. While they were there, they talked to each other.

"So, Tsu-chan… How are you doing in school? Made new friends?" Rena questioned

Tsuna was silent for a moment because the topic of school came about. He is bullied and called No-good Tsuna a lot by his classmates and his grade weren't great either, more like below average, but he did get to know some people.

"School… its okay and I got to know few people such as Gokudera-kun and Yamamoto-kun." Tsuna told her.

"Got a girlfriend, yet?" Rena said smiling

Tsuna started blushing, his face turned pink-ish. He hasn't had a girlfriend, but there is one girl he has a crush on though and he is trying his best to try and impress her.

"Just kidding" She then said giggling at the level of pink Tsuna's faced turned.

"We should head home now, its getting late." Rena notified Tsuna

At that point they went back home. When they opened the front door and walked into the living room and found their father, which happened to be sleeping on the couch.

"Father?" Tsuna and Rena said in unison

Nana had then entered the living room after hearing their voices.

"Oh, I guess he had a long trip and felt exhausted. Anyway, dinner is ready" Nana said

Later, the two of them had finished their dinner and went upstairs to prepare to go to bed. Rena had her luggage in Tsuna's room, which she somewhat unpacked to get out her sleeping bag. Tsuna had slipped under his cover and Rena had gone in her sleeping bag. Apparently, Tsuna couldn't sleep just yet; he had a question lingering in his mind.

"So, Rena-chan, are going to be transferring into a school around here anytime soon?" He asked

She waited a few seconds before answering.

"Yeah, I'll be going to your school…. Tomorrow, that is." She said

After that she ended up falling asleep, so that she could wake up early and go to school. Tsuna had stayed up for a few minutes thinking about Rena coming to school with him and then had fallen asleep.

Okay. So how was it? Any suggestions or comments?

Chapter 2 coming soon...
