Omake

Nana Alvino: 16 years

Reborn Alvino: 10 years

Reborn was sitting in his class, looking out the window, waiting for it to end even though the homeroom teacher didn't walk in yet. Him and his friends, skipped a few grades so they were now in high school. They actually had the education level of college students but they wanted to see how high school was like. They were known as the Arcobaleno because they are the youngest and smartest kids in the school and the strongest. The name was also there because of their colorful personalities.

"Hey Reborn, did you hear that we're getting two new students." Colonello, Reborns rival, a boy with blue eyes, blond hair, and an obsessive love for army uniforms, said. Reborn's ears perked at that, he didn't hear a thing about any new students.

"Really, did you see them." Reborn didn't want to admit that he didn't know but he was curious.

"Well no, but I know its a girl and a boy coming to our class." Colonello said.

"Atleast that got your attention Reborn. What were you thinking of that had you spaced out since you got here?" Lal-mirch, also called Lal, asked curiously. She is a girl with blue hair down to her waist and pink eyes.

"Oh that... " Reborn didn't even realize he was spacing out, he was thinking of what his mother told him this morning. She just dropped it like an afterthought.

"Reborn don't forget your lunch and your homework or-" A tall woman with black hair and brown eyes said.

"I didn't forget mom." Reborn rolled his eyes and sighed with one foot already out the door.

"I know but, I still can't help but worry about my children, oh and speaking of children, your sister is coming back today. Now go before your late. I'm also leaving for a month today." Reborn was pushed out the door by his mother and she shut it.

After that Reborn walked to school in a daze, lucky that he didn't get hit by a car yet.

"Do any of you remember my sister." Reborn asked, looking at the six other arcobaleno who shivered at his words.

"How could we not! She brought us to a forest for a week camping trip then left on the first day, telling us to find our way back." Verde, a boy with green hair and black eyes stated. Verde is the inventor of the group and mostly looks at things in a scientific way.

Skull, the youngest of the group by a year, slammed his hands on the table. "She almost killed the great Skull many times." Everyone in the group ignored him.

"I lost a lot of money to her." Mammon, also called Viper, said. Viper is the kid that no one knows the gender of because he/she/it always wears a hood, all they know is that the hair is purple and Viper is the same age as Skull.

"Alright students, settle down." Their teacher, a middle aged man named Mr. William, stated when he walked in the class. Mr William was one of the nicest teachers in the school and was well liked by everyone but Reborn never got rid of his feeling that something was off about his teacher. The other Arcobaleno members also had that feeling and were always wary of the teacher. All the students sat in their seats and Reborn's group stayed in the seats they were in because they somehow got the teacher to seat them all next to each other.

"Today we have two new students, be nice to them please." Mr. Williams said when it got quiet. The teacher raised his voice slightly. "You can come in now."

The door opened and in walked a familiar handsome boy with spiky black hair, brown eyes, and a bright smile on his face. He had something wrapped in cloth, strapped to his back.

Next walked in someone who made Reborn almost stop breathing because of her looks. The girl had long shiny brown hair, beautiful, captivating, caramel eyes and a kind smile but, what caught Reborns interest was the slight, but barely noticeable, smirk she had on and that glint of mischief in her eyes. The eyes of his sister. Reborn froze in his seat when her gaze landed on him and he had to resist from flinching when her smirk got slightly wider.

"introduce yourselves please." Mr. William pleasantly said.

"I'll start-" The boy said with the smile still on his face. "My name is Tsuyoshi Yamamoto, don't call me Tsuyo, only she is allowed to." He pointed to the girl next to him who rolled her eyes.

"My name is Nana Alvino, I'll answer any question, as long as it's not too personal."

The class instantly started to ask questions that could not be heard over the noise of other questions.

"Alright class, one at a time, they can't hear any of your questions." shouted over the noise. "Alright, you go." He pointed to a girl with short red hair and green eyes.

"Why did you transfer in the last year of high school?" She asked in a very rude tone of voice.

Tsuyoshi covered Nana's mouth before she could speak. From everyone else's perspective, it looked like he wanted to talk first but Reborn and his friends knew Nana would have verbally attacked the girl and made her cry.

"We wanted to see how an Italian school was like." Was all Tsuyoshi said. He gave the students a glare that said, 'don't question us on this.'

'What's her favorite color?" A boy with blond hair asked.

"A secret, and if anyone wants to know, mine is blue." Yamamoto started answering the questions for both of them, not covering Nana's mouth anymore because she bit him and it really hurt. He kept taking until one girl asked a specific question.

"Do you have a girlfriend Tsuyoshi?"

"Is Nana, by any chance, related to Reborn?" A girl shouted at the same time as the other question. Reborns last name was also Alvino but since it was just a name, many students were confident that they were not related.

"Of course their not related, they don't even look alike." A girl with dark brown hair said.

"Its probably just a coincidence that they have the same name." A boy with black hair added.

To their surprise, Nana answered the question. "Reborn is my little brother by blood, now if there are no more questions, I would like to sit. Oh, and Tsuyo does have a girlfriend. If any you go after him, she will tear you apart." She gave the students and the teacher a challenging look then grabbed Tsuyoshi's hand and dragged him to the empty seats in the back of the class, directly behind the Arcobaleno.

"Reborn, since you are related to Nana, I would like for you to show her and Tsuyoshi around the school." Mr. William said while writing on the board today's work.

"You never said your sister was coming back." Collonello hissed.

"I was about to but she already walked in." Reborn hissed back. Reborn looked behind to see Nana whispering to Tsuyoshi, both had a serious face on.

"We're not leaving you alone, we're coming to your house today." Fon, the calm and rational one of the group, said.

"You can't back out now, my mom left on a vacation and my father is still on his business trip for two more months so it's just me and her." Reborn said with a smirk. Reborn and his group already knew Reborns parents were on assassin jobs, it was just a cover-up incase one of the normal students were listening.

"How could you sacrifice all of us like that." Skull said in a whisper that was way above a whisper. Reborn only hit Skull on the back of his head.

"Reborn~" A voice said from behind Reborn that sent shivers up his and his friends back. Reborn slowly turned around to look at her. "I'll be looking after you alone for a month. I hope we get along." In her voice, Reborn heard the trouble that would be caused for him from now on

By the end of the day, Reborn learned that Nana was in most of his classes and when it wasn't Nana in his class, it was Tsuyoshi.

"School is finally finished." Collonello shouted with his hands in the air as they walked pass the school gates.

"Idiot." Reborn said with a smirk on his face which caused Collonello to throw the first punch punch and they both ended up fighting. That fight made the group feel like today was a normal day and they forgot all about Reborns sister. That is until Nana and Tsuyoshi interrupted the fight. Tsuyoshi grabbed Colonellos collar while Nana grabbed Reborns collar, lifting both boys off the floor.

" Ha ha, It felt strange when both of you didn't fight all day" Tsuyoshi said with his happy grin still on, gently setting collonello on the floor. Reborn was just dropped on his feet and Nana's hand rested on his hair and started to run her fingers through those dark silky locks.

Reborn didn't wanted to admit it but he really loved it when his sister ran her hand through his hair. When he caught himself starting to relax he shook her hand off his head and stepped away to face her. He learned from her the hard way what happened when you turned your back to the enemy, with two weeks in the hospital.

"What are you doing here?" Reborn didn't miss the glance Tsuyoshi and Nana exchanged.

"We're here for school." She dismissed him with those words then turned to walk in the direction of their house.

Reborn's friends were talking while Nana and Tsuyoshi talked in front of them. Even though he was replying to every question his friends asked him, he was still listening to what his sister was staying. When they reached the house a certain part of the conversation kept playing over in his head.

'What information did you get?' Nana whispered.

'He seems normal to me, are you sure it's the right person?' Tsuyoshi whispered back.

'Do you doubt my information?' She harshly whispered.

'I doubt your informant.' He whispered in the same tone.

' Why, because he's from the same famiglia as that man." Nana slightly raised her voice.

'he may be working with 'him'. Tsuyoshi whispered in a calmer tone of voice.

After that the conversation stopped. Who are the people they were referring to? Reborn thought right before he and his friends walked into his house.

Nana stopped in front the door staring straight at the doorknob and spoke in a sweet voice. "Reborn can you open the door for me, I don't have my keys."

Reborn sneered, she saw right through his trap. "Lackey go open the door." Reborn handed the keys to Skull and kicked him to the door. Everyone watched as Skull got shocked as soon as he put the key in the keyhole.

Nana laughed as the door swung open. "So the prank wars continue. You need to step up your game little brother."

Reborn was sitting in the training area with his friends, which is where his sister literally dragged them, one by one. The training area was in the basement so explosions and screams couldn't be heard. It was a place Reborn loved to visit because of the many simulation rooms and the large open space. Right now they were in that large open space. Nana and Tsuyoshi were facing Reborn and his friends who were lined up side by side.

"I haven't been here in a while so let me see how you have progressed." Nana said in a commanding voice. "Reborn first." She gave a frightening smirk.

Reborn stepped up with a shiver. This was not going to end well.

Having Tsuyoshi there reminded Reborn why he liked him so much. First, Tsuyoshi was kind and second, when he was around, Nana's mischief was turned toward him. After the training session Reborn and his friends were panting on the floor almost half dead. They all had various bruises and cuts, even Lal got it rough. Tsuyoshi was the one to patch up their cuts and bruises and he was a gentle teacher. He always came with Nana when she came back home and he traveled everywhere with her. They at first thought that both of them were dating but then they learned that Tsuyoshi was saved by Nana on a mission where his parents were killed. He devoted his life to her after that and was learning a sword style from a friend of Nana and Reborn's uncle.

"Tsuyo your too kind." Nana grumbled. They were all in the living room while Tsuyoshi took care of their injuries. While fighting them, Nana and Tsuyoshi barely broke out into a sweat.

"Well one of us has to be." Tsuyoshi rolled his eyes while putting a bandaid on Fon's arm.

" Whatever, I'm going to cook. I'll get you for that comment later" Nana walked in the kitchen to make dinner. Cooking was her favorite activity because it allowed her to gather her thoughts.

"Tsuyoshi, tell us the real reason why you're here." Reborn said with his arms crossed in an imposing position.

Tsuyoshi let out a nervous laugh. "Were here for school didn't we say that already."

"Tsuyo don't give them that bullshit excuse, my little brother is smarter than that, although he still can't eavesdrop properly." Nana said with her arms crossed in the door way of the kitchen. A ladle was in her hand and a sharp knife in the other.

Tsuyoshi looked at both Nana's and Reborn's similar positions and shivered. For siblings who hate each other they sure do act alike.

"I finished my training so I'll be here permanently. There is also someone we are after." Nana continued.

Reborn was confused. Why would she tell me this now? She usually never talks about her missions.

Nana let out a small laugh. "You are so easy to read little brother. The reason I am telling you this now is because you and your friends are going to help me with this mission."

A/N: The reason why I wanted to end it here is because this Omake is two parts and I wanted to update my story. I have been so lazy these past weeks but I have to start searching for colleges that have my major. Also my laptop is broken so I have to do this on my kindle. Thank you all for being patient with me. Whoever can guess Nana's flame will get something or someone they want from the story to appear, no pairings yet, I'm not ready for those. R&R XD
