Chapter 1: New year, new term, new students

Time: Present (A year after the arcobaleno curse is lifted)

"Hiieeee! Ouch!" Tsuna just fall down from his bed as he woke up just in time to avoid being hit by the 10 tonnes hammer. Reborn has upgraded the hammer since Tsuna has become immune to the one tonne hammer.

"Geez, Reborn, won't you get tired trying to hit me every morning to wake me up? Can't you even be gentle just for a little bit? Normal people would have died from that, you know?"

"But, you are not normal people, Neo Vongola Primo. And I was just trying to train your reflex. Besides, the word gentle is not in my dictionary. See?" Reborn smirked while showing Tsuna a dictionary (it was actually Leon who turned into a dictionary). The five years old ex-arcobaleno then kicked Tsuna out of the room. "Anyway, you better hurry up, dame Tsuna. Gokudera and Yamamoto are waiting for you downstairs."

"Morning, Juudaime/Tsuna". Tsuna was greeted by Gokudera and Yamamoto as soon as he goes to the dining room.

"Oiii, you baseball freak, I was supposed to greet Juuidaime first!"

"Maa maa, isn't it the same if we greet him together?"

"Morning, kaa-san. Morning, guys."

"Ara ara, morning Tsu-kun. You better hurry up and eat your breakfast. You don't want to be late on your first day as a high school student, aren't you?" said Nana while placing the breakfast on the table.

"That's right. We better hurry up, Juudaime. I have a feeling that the skylark will be on a bad mood today."

"Ehh, why?" Tsuna is confused. Shouldn't Hibari-san be happy now that he can spend the whole day in school?" "Don't tell me you have forget, Tsuna? There will be more students in the school this year since one sixth of the students from the Teitan High School is going to be temporary placed here."

"I bet the skylark will be very irritated since more new students mean that the peace of the school will be disturbed considering those people doesn't know the skylark's rules yet." added Gokudera.

"Ohh, I forgot. Thanks for reminding me." Tsuna smiled sheepishly. Tsuna got kicked by Reborn again.

"A boss shouldn't forget things easily no matter how unimportant the matter is. Looks like I need to double your training". Tsuna sighed upon hearing that. Feels like I gonna die someday because of those 'training'. Just what did I do in the past to deserve this sadistic tutor?

After breakfast, the trio walk together to the school. "I wonder will Shoichi transfer to our school too. If I recalled correctly, he study in Teitan Middle School. And I also wonder just what has happened to the school that they decided to transfer their students temporarily to other schools?" Tsuna said suddenly.

"I heard that their school was burnt down halfway due to some accident, Juuida.." Gokudera was explaining to Tsuna when the three of them heard someone screaming and run passed them, almost crashing into Tsuna.

"Sorry, Tsuna", the guy that ran passed them yelled without turning to face them.

Enma was walking alone to school when two dogs appeared suddenly out of nowhere and start to chase him. He has no choice but to run for his life.

"That idiot. How dare he almost crashed into Juuidaime. He could just use his power to pin down those dogs"

"Hahaha, Enma has poor luck with dogs as usual" Tsuna could only sweat dropped while looking at both his friends' reaction.

xxxxxxx

"Alright, class. Please be quiet and settle down at your seat. Today, we have three new students in our class." A teacher enters Tsuna's class with a certain white-haired boy.

Hiieee, what does Byakuran doing here? Tsuna was shocked and panicked internally when he saw Byakuran wearing their school uniform and standing in front of the class with their homeroom teacher. Not only Tsuna. Yamamoto, Gokudera, Chrome and Enma were surprised too although they didn't show it on their face.

"Please introduce yourself to everyone, Byakuran." The teacher said.

"Hi, everyone. My name is Byakuran Gesso. You can just call me Byakuran. I transferred here from Italy. Nice to meet you." Byakuran smiled cheerfully while introducing himself. Some of the girls already started to blush and fangirling as they looked at the hot new student in front of their class.

"Oh, from Italy. Just like Gokudera-san", one of the students said. "That's right. I actually transferred here just to be with the same class as Tsu-chan", Byakuran added while walking towards Tsuna's seat and try to give Tsuna a hug. Gokudera almost explodes when he sees Byakuran trying to hug Tsuna and quickly holds Byakuran's arm.

"Just what do you think you are trying to do to Juuidame, you marshmallow freak?"

"Trying to give my Tsu-chan a friendly hug, of course. It's has been quite some times since I last saw him. Do you want a hug from me too, Gokudera-kun?", Byakuran who is still smiling turned around to face Gokudera.

"Maa maa, calm down, Gokudera. It's not like he is going to harm Tsuna or anything". Yamamoto trying to calm Gokudera down before he starts to throw bombs at Byakuran. While the scene is playing in the class, more than half of the students in the class were wondering how does dame-Tsuna be friends with hot/popular guys. First is Yamamoto and Gokudera and now this new student. Meanwhile, Tsuna is depressed now. With Byakuran around, he doesn't need his hyper intuition to know that every day will be chaos. At least, this couldn't be getting any worst, right? Tsuna asked himself.

"Ehem, Byakuran, can you please choose your seat and settle down? Same goes for you, Gokudera and Yamamoto. Please go back to your seat", the teacher said.

"Sensei, aren't you saying that there are three new students? Where are the other two?", Hana asked.

"They are in the registration office right now, filling some forms. Both of them are from Teitan." As on cue, the classroom door slide open, revealing two people. One boy with red hair and wearing spectacles and one girl with a very dark brown hair that is usually mistaken as black by most people.

"Both of you are right on time. Please stand here and introduced yourself", the teacher welcomed the two new students. The red haired boy decided to introduce himself first. He was actually on the verge of having his stomach ache when he saw a certain white-hair boy sitting behind the class. What is Byakuran-san doing here? He panicked internally just like Tsuna.

"Good morning, everyone. My name is Irie Shoichi and I'm transferred here from Teitan. It is nice to meet you all."

"Hi, everyone. My name is Sendou Akiko. You can call me Kiko for short. Just like Shoichi, I'm from Teitan's too. I hope all of us can get along well together." the girl smiled at everyone while blushing slightly. She was not used to standing in front of so many new people and she was a shy person to begin with.

"Alright, both of you can go take a seat beside Byakuran, the guy with the white hair." The teacher pointed to the seats beside Byakuran. Both of them nodded and go to their respective seat.

"Psst, Byakuran-san, what are you doing here?", asked Irie when he sensed that the teacher is not looking at him. "Ehh, ohh, it's you. Sho-chan. You are here. Well, I talk to you later". Byakuran wasn't really paying attention right now, so he was a bit surprised when Shoichi called him.

In fact, he can't focus ever since he saw the girl stepped into the classroom. Isn't she Koko-chan? There is no mistake about it. I'm so glad she's alright. But, somethings is not right here. Why she didn't recognise me? Just what has happened in the last seven years after you went missing? I need to ask Sho-chan about this. He seems to know her well.

A/N: This is the current age of the characters:

Tsuna and his friends – 16

Hibari, Mukuro, Ryohei, Byakuran and Akiko – 17

Irie – 16 (I know he is younger than the Tsuna in the anime, but I need to change it to suit this story)

The rest of the arcobaleno except Lal : 5 or 6 years old. The arcobaleno grows faster than normal kids after the curse is lifted. One year is equivalent to three years for them.

About the Teitan School, I just created it because the anime/manga didn't specify which school Irie went. And the words in italic represent monologue. By the way, this story will be quite long. Possibly more than 15 chapters if I din't get stuck half way. ( Let's hope I din't get stuck. This is my first fanfic afterall). Anyway, hope you enjoy the story and feel free to comment. _
