"..." talking

'...' thinking

Chapter 4

The school was over and Tsuna still worried about his new friend. He didn't see her after lunch and that make him more worried. He scanned his surrounding to find her.

'Where is she? I hope Hibari-san didn't bite her to death,' Tsuna desperately tried to find his friend trail.

"Tenth. Just leave that woman. She doesn't deserve your worry."

"But ..."

"Tsunaaaa~" Aurelia shouted beside his ear. That made him jump several feet.

"Hiiiiiiiiiiiiiiiiiiiee! Aurelia-san! Don't do that! You almost make me have a heart attack!"

"Hehehe~ Sorry Tsuna," she grinned when saw Tsuna's reaction.

'He's so much fun~. I want to tease him more,' her grin got wider when she thought about what she will do to her "new toy".

"Che. What is so funny, stupid woman? You grinned like a idiot."

"Hahahaha... What's so funny Aurelia-chan?"

"Aurelia-san, are you okay? Did you meet Hibari-san? Are you hurt?" Tsuna asked worriedly. He looked at Aurelia with worried cute big brown eyes that reminded you of a bunny.

"Aaawww...Tsuna, you're so cute and adorable~" she hugged Tsuna that made him blushed ten sheds of red. She grinned even more and hug tigher when she saw Tsuna's blush.'He's so cute, adorable, and honest. Really different from someone I know.' She really hope that if it's possible Xanxus's behavior was like Tsuna, just a little bit was enough. Althought Tsuna was hopeless, useless, and wimp but he has a good side that nearly covered his weakness.

"Oi, stupid woman! Release tenth immediately!" snapped Gokudera. He was angry and ready to pounced her to release Tsuna.

"Maa maa... Calm down Gokudera," the baseball star held in Gokudera and tried to calm down his friend.

"Shut up you baseball idiot! Release me!"

"Maa maa..." he gave him his carefree smile and added."Ah, by the way Aurelia-chan, can you please release Tsuna? It seems that Tsuna can't breath because of your hug."

"Eh? Ah, you're right. Okay then," she released Tsuna and immediately he tried to catch his breath. His head was a bit dizzy because of lack of oxygen.

"Sorry Tsuna. It seems that I'm too excited. It can't be helped though. You're so cute," she remarked and laughed a bit. Tsuna just smiled weakly at this and suddenly he remembered something he wanted to ask earlier.

"By the way Aurelia-san, did you hurt somewhere?" Tsuna take a look at her friend. Searching for some injuries.

"Nope. Why did you expect me to hurt?" she looked confused by her friend's question. Why she must be hurt? It was no sense. Truth to be told that she felt insulted at her friend's remark.

"B-be-because the one you facing is Hibari-san. He's the strongest person in Namimori, " He looked pale and scared. No doubt that he scared the shit out of the prefect.

'Ara ara~ What a wimp and coward boy. Poor Reborn. He must changed him completely so that he can be a good vongola boss,' in someway she almost pitied Reborn because of Tsuna's cowardliness is undefeated. Almost. I remind you.

"Hmph... Just because I'm facing Hibari, It doesn't mean that I must be beaten up. Do you want me to be beaten up, Tsuna? Despte your cute face, you're so cruel~" Tsuna sweatdropped at her friend's sarcasm. He really astonished and curious by how Aurelia survived from Hibari punishment. His intuation told him that she wasn't an ordinary girl. Something about her seem a bit off. He thought that maybe. MAYBE. Aurelia was one of Rebon acquaintance that was asked by Reborn to train him. But if that's the case why Reborn hasn't told him anything? He shook his head and shrugged it off. Maybe he is just too paranoid about this mafia thing and begin thinking too much.

"Tsuna? Tsuna~. Are you still there?" Tsuna snapped out of his mind. He didn't realized that his friends stared at him the whole time.

"So-sorry everyone. I'm just thinking about something," he smiled sheepishly. It was embrassing to him to be caught lost in thought in the middle of conversation.

"What is in your mind Tsuna? You seem pretty lost in deep thought," asked Yamamoto curiously. It wasn't everyday that his friend had a deep thought.

"N-No. Nothing at all. It just an unimportant stuff," Tsuna reassured his friend. He didn't want to talk about it. It doen't feel right if he accused her involved in mafia or something like that. Yamamoto tilted his head in confusion.

"Just leave tenth alone, you baseball idiot! If he didn't want to tell you then that's it! You can't pursued him!" Gokudera shouted at Yamamoto. They started their usual bickering again. Although it just one side.

"S-so Aurelia-san, do you have free time after school?" Tsuna asked.

"Yes, I have plenty. Why did you ask?"

"D-do you want to come over to my house? We want to study together for the upcoming test. Do you want to join?" Tsuna stammered. He hope that she doesn't see him weird because he invited her over in her first day. Althought he wanted to change the topic, he didn't know what topic he should say. Just invited her over that crossed his mind.

"Sure~. Sounds like fun. I don't have anything to do afterall," she grinned cheerfully. For her it's a nice chance to know better Tsuna's family. After all her mission was to watch over and spy them.

"Then let's get going. If we still at school after school hours, Hibari-san will bite us to death," but before they stepped out of the school, Hibari stood in front of them, blocking their way. He gave them stern look especially toward the dark haired girl.

"New herbivore. I need to talk to you."

"Ara ara~ Why are you here .chan~?" she teased. Not forget to press the word 'Kyouya' clear and loud. Students around them stopped what they were doing and stared at the two. They stunned at the new girl's boldness. No one ever dared to call the prefect by his first name morever using suffix chan. Crazy. She is crazy. They don't know if the girl was very brave or just plain stupid. She really has a death wish. They can feel the prefect's wrath increased. Oh no... she's doomed. The new student will dead. He will give her a painful death. The students began trembled in fear. Silence engulfed them. No one dared to move or speak. It's like if the silence broke, the hell would broke loose. The tension between the two began thicker every second passed. He gave her a menacing glare.

"Who was the one who give you permission to call me by my name, herbivore?" he growled at her. Tonfas already stand by in his hands.

She giggled. Her eyes shown amusement. "Actually no one. But do I need someone permission to call you by your first name? So bossy~. And arrogant. By the way, my name isn't herbivore but .li.a."

He snarled. That's it. She already cut his patience string. "I will bite you to death."

"Yadda. I have some business to do after this. Just state what do you want so I can leave."

The students gasped. 'She's suicidal!' they screamed in their thought. 'She will death for sure!' 'Oh My God. She's crazy!'

Tsuna gasped in horror. He knew that his new friend was blunt, ignorant, brave, and maybe a little weird. He hoped that this time his friend was normal and the sane one but noooooo! She's more d troublesome and insane than Gokudera. He felt like crying inside. Why God hate him so much?

'Hiiiiiiiiiiiieeee! She will be bitten to death by Hibari-san. What should I do?' Tsuna panicked. He tried to think how to save his friend. But what can he do? He's Dame-Tsuna afterall.

"Tsuna. Save her with your dying will," a baby voice spoke behind him.

"Eeeh?"

BANG!

Suddenly a fire appeared in Tsuna's forehead and his clothes tore apart. Leaving him with a boxer with Tuna pattern in it.

"REBOOOORNNNNN! I WILL SAVE HER WITH MY DYING WILL!"

In a blink of eye Tsuna already lift her up to his shoulder and ran away. Leaving a trail of dust behind him.

Yamamoto, the first one who snapped out of the shock, tried to chase after Tsuna.

"Tsuna, wait for me!"

"Oy Baseball freak! Don't leave me! Tenth!" snapped out of his thought, Gokudera also start to catch up with Yamamoto. Leaving the remain student still stunned in shock. When they're out of shock, the four student already out of their sight. Realize this, Hibari gritted his teeth in annoyance. Tomorrow he will get them for sure especially that new girl, Aurel or whatever her name.

"Tsuna put me doooooown!" Aurelia yelled at Tsuna. She already snapped out of her shock a few minutes ago and has yelled to Tsuna to put her down but he didn't budge at all and kept ignoring her.

"Tsunaaaaa... put me down! It's embarassing!" Aurelia yelled again.

'Is he deaf or something? I swear if he don't put me down this instant, I will give him a whack in his head with my full power!'

"Tsu- Waa!"

Suddenly Tsuna put her down without warning much to her dismay. His fire in his forehead also extinguished after he put her down.

'Finally,' sighed Aurelia. 'It's so embarassing to be carried like a sandbag. Even less I was carried by someone who is shorter and weaker than me. I feel humilated,' she groaned and sulked in the corner. 'Ugh... I even don't want to imagine their reaction if they see me be carried like that. Especially 'those two'! I even can hear their snicker and laughter now.'

"lia... Aurelia-san... are you alright? Aurelia-san?" Tsuna asked. He is worried because her friend was sulking in the corner and didn't move an inch.

"Please bury me in the deepest shit pit hole. I don't have face to meet them," she mumbled gloomly.

"E-eeeeh?"

She looked up at Tsuna. "Ah... Tsuna. I'm fine. Maybe," she muttered the last part.

Tsuna sigh in relief. "Then, do you want to come inside?"

"Eh? Inside?" Aurelia asked. She tilted her head and gave him a confused look .

"Ah. It seems that I brought you to my house," Tsuna laughed weakly. Aurelia's eyes widen when she heard that.

'Already in his house?' she look at her surrounding. True to be told that in front of her was a house that has a Sawada's name in the front part.

She looked at Tsuna in disbelief. 'Is he really as weak as I have been told? It's impossible for him to carry me from school to his house if he really weak. Tsk. I must revise the information. Maybe the information is already out of date.'

"Tsuna, What training did you do? Althought my weight is ideal, I don't think that you can carry me with your petite body."

"E-eeeh... What training you mean.. Uuuh... How I put this," Tsuna panicked. He didn't want to tell her that he is a mafia. A candidate of mafia boss to be exact. He is already enough of the mafia crap. Let alone if he told her that a baby is the one who is training him. She won't believe it for sure.

"Tsuna?"

"U-uuuhh... This is...umm..." 'Anyone save me!'

Fortunately for Tsuna, his prayer was granted with a swift kick in his head.

"I-itteee..tee... Reborn! What are you doing?"

"Nothing, Dame-Tsuna. Just come inside already. Do you want to be naked outside forever? The neighbor is staring at you, you know," truth to be told that many people staring at. Whispering among themself about Tsuna naked figure.

"Hiiiiieeeee! I forgot that I'm naked!" Tsuna stepped into the house in hurry. Leaving the two outside.

Aurelia stared in annoyance at Reborn. 'You purposely change the subject, aren't you?'

'So what?' he just stared back at Aurelia. A glint passed his eye.

After several minutes of staring contest eeerr... no. I'm sorry it. It was a glaring contest, Tsuna came back outside. Full dress this time.

"Umm... Aurelia. Lets go inside. My mother want to meet you when I talked about you a while ago," Tsuna smiled sheepishly. He glanced at Reborn. His smile turned into a frown. Confused written in his face. It's really clear that Reborn didn't like the new transfer student. But why? He never see him like this.

She broke the intense staring contest and headed to Tsuna. "Okay."

Before the two of them stepped into the house, two familiar figures approached them.

"Tenth!"

"Tsuna."

"Gokudera. Yamamoto," Tsuna suprised when he saw his two best friends.

"Wow. You running really fast Tsuna. I even have hard time to catch up."

"Of course Tenth is always great, baseball idiot!"

"Maa maa..."

"Guys. Let's get inside. You will disturb the neighbor," interupted Tsuna. He didn't want them to start their usual bickering in the outside that can make the neighbor gave him more staring than now. He didn't need more attention. Thank you very much.

"Yes tenth!"

-Inside the house-

"Gyahahahahaha... Lambo-san is here. Bow to Lambo-san, Dame-Tsuna!" a 5 years old kid with cow suit and afro hair announced his presence.

"La-lambo.. please be polite in front of guest," Tsuna tried to calm down the hyperactive kid. He looked at Aurelia with a apologetic face and mouthed a sorry to her.

"Aho-shi! Don't call tenth like that!" Gokudera shouted at Lambo. He stomped on Lambo to silence him. Fortunately for Lambo, he's quick enough to dogde the upcoming attack.

"Like I care Baka-Dera!" Lambo sticked out his tongue.

"Maa.. Maa.." Yamamoto tried to calm down the silver haired man.

"You-!" Gokudera almost took out his dynamite when suddenly he was interupted by Aurelia's voice.

"So..."

"Eh?"

"So cuteeeeee~" squaled Aurelia. She ran to Lambo and hug him tightly. She rubbed her cheek to Lambo's. "So soft~" she pinched his cheek. "So adorable~"

"Gyaaaa! Release Lambo-san!" Lambo said with tear threatening to spill. He is squirming and struggle to get off this stranger's hug. Her hug is crushing him.

"Why~? You're so cute. I want to continue to hug you," Aurelia pouted like a child. Truth to be told that she like children. Especially the cute one. Ah, except Reborn because he's to dangerous and althought his appearance is a cute baby, she knows in the inside he's a dangerous man with age more than triple of her age.

Tsuna and Gokudera sweat dropped at this. They never meet a person more strange than her. And Yamamoto just laughed at Aurelia's behavior toward Lambo. It seems like he has a very interesting new friend.

"Aa-aurelia-san please release Lambo. He can't breath."

Aurelia looked at Lambo. Seeing him nearly burst into tears, she released him immediately.

"Oh. I'm sorry. Your name is Lambo right? Here I will give you a candy. Please don't cry okay?" she gave him a grape flavored candy. Seeing that Lambo immediately took the offered candy and ate it happily.

"Lambo-san love grape. Onee-chan Lambo-san want more!"

"E-eeehh? Lambo! No, you can't!" Tsuna shook his head and gave Lambo a No-sign.

"Why not Dame-Tsuna? Lambo-san want more!"

"Lambo-!"

"It's okay Tsuna. Here I will give you more." she handed out several candy to Lambo.

"Yeeey~. Lambo-san loves candy. Lambo-san likes onee-chan. You can be Lambo-san's subordinate," Lambo said with full of cockiness.

Aurelia just chuckled at Lambo's antic. "Sorry Lambo. I can't be your subordinate. But I can be your friend."

Lambo brighten at her reply. "Then play with Lambo-san!"

"La-lambo. You can't compel Aurelia-san to play with you. It's rude. Besides, she has another thing to do."

"No no. It's alright. I will watching over him when you do your homework. I love cute children afterall," she smiled and winked at Tsuna.

"But-"

"Tsuna. It's o.k.a.y." she looked at him with a determined eyes that left him no choice. Tsuna sigh in defeat.

"Okay. And I will be in the upstairs if you need me," Tsuna smiled at Aurelia and walked away to his room in the upstair with Gokudera and Yamamoto.

"Aurelia-san."

Aurelia looked up to see Tsuna standing behind her.

"Sorry for troubling you Aurelia-san. Lambo is handful." he smiled sheepishly

"No problem Tsuna. He's cute so I don't mind."

Tsuna sweat dropped at her answer. 'Just because Lambo's cute she played with him and deal with his whining until night?'

"T-th-then as a thank you would you like to eat dinner with us?"

"Eh? Is that no problem?"

"Yes if you're okay with the okaa-san insist afterall."

"Thanks Tsuna. It was pretty lonely to eat dinner alone. I'm pretty used to eat with A LOT of noise," she press the word 'a lot' to make her statement more clear.

Tsuna laughed weakly at this. "Well, let's eat. Dinner is ready."

He helped Aurelia stand and led her to dining room.

-Aurelia's Apatrment (temporary) -

"Tsuna's family is interesting."

She chuckled when she remebered the chaos at dinner in Tsuna's house.

'Maybe they're not as bad as I thought,' she sighed and looked at the starry night sky. 'What will you do Xanxus-nii? It seems that Tsuna will be a great opponent to you.'
