Day 2: Today Is A School Day Right?

.oxo.

Smack!

Tsuna rubbed the bump on his head that a certain baby obviously hit and narrowed his eyes. He took note of his delicate-looking hands and his somehow long and down hair.

Then, he gasped as everything that happened yesterday came crashing in his mind.

"HI—!"

Smack!

He—well, she now was about to let out her signature scream when she got hit again on the same spot as before for the second time.

The brunette rubbed her head again—this time, glaring at the cause of the pain.

"Reborn! Why—"

Smack!

Another bump.

The girl rubbed her head for the third time with angry veins popping in her head.

"Don't go shouting now, Dame-Tsuna. There's people still sleeping," Reborn said simply as he patted Leon on the head.

Tsuna blinked and stared at the digital clock which was coincidentally next to her.

"4 o'clock in the morning?" she muttered aloud angrily and glared harder at the hitman though she did lower her voice. "Why did you wake me up? School's not even starting!"

"I wanted to be sure you remember," her tutor sat on her bed and the mafia boss did as example but did titled her head in confusion.

"Eh? Remember what?" Tsuna asked the hitman who in turn sigh.

"Figures," the baby mumbled to himself and looked straight at the teen. "Do you not remember what I explain yesterday night?"

"Yesterday," the long-haired brunette titled her head and thought hard about last night. She got an image of her screaming the bath room, going out with a towel and asking why there's blood on her butt. And also Reborn explaining something that she couldn't seem to hear and her fainting at the explanation. "Um... no?"

The sun arcobaleno smacked her with a green hammer again and let out a very long sigh.

"Dame-Tsuna, I'm going to explain it again and this time stay awake and listen. Got it?"

Tsuna nodded like an obedient pupil and stared at her tutor who was very much embarrass to explain this kind of stuffs to the girl if the slight blush was an implication enough though it didn't seem like the boy-turned-female noticed this.

"The blood that you saw yesterday was a normal occurrence that happens every year for a girl and since you're a girl now, you'll be experiencing them," Reborn said a little weird from telling this to his student who was once a boy. "You'll also have those mood swings that girls have and since you are a boy for your entire life, you'll be PMSing in this one week of being a girl."

"Why do girls get bleed every year? Why do girls have mood swings? And what's PMSing?"

The baby seemed to sigh again. He didn't seem to like to answer those questions but not like he had a choice, now did he?

"Tsuna, didn't your teachers already teach you about the female reproductive system?"

Well, he at least wanted to delay explaining a little bit.

The student thought for a minute but her mind was blank. "I forgot," she answered, scratching her head in embarrassment.

Reborn would have teased her but she was quick to defend herself.

"What?! It's not like I know I would be turn to a girl one day!"

The sun arcobaleno pouted at her comeback and for some reason, the girl couldn't help herself and hug the baby in her arms.

"Cute!" Tsuna shrieked girly and she froze at that. "What? I just loss control and..."

"That's your female hormones," her tutor answered for her, looking somehow smug in her arms. "I seem to still attack females after all, even if the female is once a male."

The brunette didn't know if she should smack him or just hug him tighter. He was getting cuter in her eyes now.

"Wait! Don't change the topic," she scolded him and was she shocked at how she sounded just like her mother. "What's with the blood, mood swings and PMSing?"

"Well, like I said the blood is normal for girls so they could reproduce," Reborn said slowly as possible and smirked at the paling of his student who might had a knowledge at what's he's saying now. "Mood swings are just normal for girls in PMSing and PMSing is the period where girls are easily angered and annoyed and can be scary as hell."

"I...see," Tsuna muttered awkwardly and somehow looked anymore than the hitman in her arms. "So...why did you wake me up so early?"

Awkward Silence...

"Tsuna, you're going to school as a girl and I'm going to teach you about the stuffs girls need."

The said female stared at the arcobaleno blankly and was going to scream but stopped herself as a thought came to her.

"This is why I fainted yesterday, right?"

A statement.

Reborn just chuckled and nodded at that.

"So why don't we start now?" he wiggled his way out of Tsuna's embrace and stood up.

And the brunette could only wished it would be easy.

...

Lesson 1: Dressing Up

Two blank brown eyes stared at the thing in the baby's hands.

"Reborn! No! Just no!"

"Shut up, Dame-Tsuna! You have to wear it!

The sound of gunshots and curses were exchanged.

"But god, they're itchy and just uncomfortable and why the fuck do girls even insert that with their panties?!"

"Do you want to have stain in your skirt?!"

The hitman already at his limits but could still control himself from shooting the naked brunette next to him.

"What strain?!"

A silence was all that answered the female before she slapped herself.

"...oh wait, blood, right?"

"I'm beginning to think this is useless..."

The arcobaleno couldn't help but make a long sigh.

"Of course, it is! I'm still a guy at heart, you know?!"

"Want me to use the Dying Will Bullet right here and now?"

Reborn crooked his gun in irritation.

"...give me the napkin or whatever it's called."

Tsuna sighed and gave up.

"Good, now try the bra."

"...Reborn."

The girl raised an eyebrow at something weird about the picture.

"Yeah?"

"How'd you get my size? It fits perfectly."

The baby tensed a little but nonetheless didn't waver.

"...hurry up, Dame-Tsuna. It's already 5 o'clock and you still have to learn."

"Don't ignore the question!"

"Oi, Reborn!"

"Wear the school uniform next."

The said male pointed at the clothes which consisted of a skirt, ribbon and a blouse.

"...no."

The brunette eyed the skirt in distaste, forgetting of her question for now.

"Dame-Tsuna."

Reborn was nearing his patience.

"Look at it!"

The young female pointed at the skirt in clear hatred.

"It's a mini skirt and you expect me to wear something like that?!"

"Dame-Tsuna, go die."

He pulled the trigger and bam.

"REBOOOORN! I WILL WEAR IT WITH MY DYING WILL!"

Reborn sighed in contentment and drunk a coffee.

"Much better."

Wonder how no one woke up from their shouts.

...

Lesson 2: Talking

Tsuna felt a vein in her head.

"What do you mean I got to talk cute and not tomboyish? And why the hell are you saying I should be all cute and try to seduce every boys?"

"I mean, be a flirt and get yourself a boyfriend since you still haven't and we need heirs."

"Reborn... I'M STRAIGHT AND DON'T LIKE BOYS!"

"Straight but don't like boys then doesn't that mean you're lesbian?"

The brunette clenched her knuckles and gritted her teeth.

She just knew this was a revenge from the first lesson.

"IGIYGHIUGFWEDRS!"

Reborn stared at the now breathing heavily female.

"Wonderful vocabulary. Who taught you those words?"

She glared at him and still had a vein in her head.

"Xanxus."

The baby turned quiet for a minute before a smirk came to him.

"Good idea. Let's visit Xanxus next."

Tsuna stared at him blankly and banged her head to the wall.

Seeing as the girl could talk (note: curse) as well as Xanxus, the sun arcobaleno deemed this lesson done and the said girl deemed this lesson as a trash.

Ah! She really learned from Xanxus. Wonder how that happened.

...

Lesson 3: Difference of Girls from Boys

"So Dame-Tsuna we're going to take on your knowledge of the difference between boys and girls," Reborn started but then paused when he saw the blank look of his student, raising an eyebrow. "You do know some differences, right?"

"Of course, I do!" Tsuna quickly replied, upset that he was underestimating what she know about females. "Well, girls can be pregnant, uses make-up, have well...b—" she slightly muttered something before continuing. "—looks pretty, the period thing, mood swings and PMsing."

Inwardly the sadistic tutor was impressed but outwardly, he was smirking at the answer. "I see, you know important different about them and remember what I taught," he teased, enjoying the sudden gender change of his student if she was this easy to embarrass. "You sure you weren't born a girl? I've seen your baby pictures where you dressed up as a female..."

"What?!" the brunette blushed so bad that it reached her ears. "I thought I told Okaa-san to burn those pictures!"

"Well, she didn't and I can see some your friends saw it as well..."

"WHAAAT?! NOOOO!"

After all of this, the Vongola Decimo was sure she would have a heart-to-heart talk with her mother and speaking of Nana, where was she? She was gone since yesterday.

...

And after those many lessons which involved Tsuna being embarrassed to hell, Reborn now deemed the girl worthy to go to school and said female could just imagine their being a camera which captured everything that happened to her lessons.

"Oh, right...," Reborn started with a very much familiar smirk. "It's already 7am."

The brunette widened eyes and shrieked like normal. She quickened her pace to go to school.

She was blur and the only thoughts in her mind were: 'I'm late! I'm late! And I'm sounding like that rabbit from Alice in Wonderland!'

Tsuna stared at the gate where a certain perfect should be and gulped as she saw Hibari standing on the gates biting anyone that passed with couple of bruises from yesterday.

"Omnivore."

She turned to the perfect and flinched in fear at the murderous eyes of the other. She closed her eyes and waited for the impact of any attacks.

But then opened them again in caution in feeling nothing.

The brunette was staring at her cloud guardian that now was staring at her in confusion.

"You're a girl."

Awkward Silence.

"Wait! No, I'm not!" blushing madly for odd reasons, she quickly denied and added as aftermath. "I'm a boy but for a week, I'm a girl!"

Though she did had to wonder about something.

'Did he fight me yesterday? Shouldn't he know by now?'

Awkward Silence.

Tsuna felt she should move now. Really go now.

"Omnivore," Hibari started, his hands already having his precious tonfas. "For turning into the opposite sex, I'll bite you to death!"

"WHAAAT?!" she screamed in fright, avoiding the attack via her intuition and ran for her life while thinking, 'What kind of reason is that?!'

...

Tsuna felt veins kept on popping in her head.

"Dame-Tsuna, why are you wearing a wig and the girl's uniform?"

"Don't tell me you're a girl... But then again, you're a cute one though an A-cup."

"How about "no assets" instead?"

"Or maybe you're a pervert trying a girl's clothes?"

Then all the laughter and teasing from the boys, except from you-know-who, stopped when they felt a sudden change in the aura of the boy-turned-girl.

They watched in caution and confusion as the brunette smiled sweetly at the teacher who was a female glaring at the boys furiously.

Ah, speaking of females, why did it seemed like all the girls were glaring at them, even and most especially Kyoko and Hana?

"Sensei, is it okay for someone to leave the class with broken bones~?" Tsuna asked oh so innocently and the boys shivered in fear at the words.

They stared at each other and then to the females who were smiling evilly and then to the to boys who were glaring at them and gulped.

Oh, they're dead.

"Of course, Tsuna-chan," their teacher answered and chuckled like an evil witch.

The situation of Tsuna being a girl for a week was explained already but the boys seemed to like to tease the now female and that wasn't really nice.

Especially if they insulted a female's size.

'That's favoritism!' the boys thought to themselves but never found themselves saying it since the other teachers also took the female's side.

"Hmph, boys," Tsuna muttered angrily, forgetting she was once a boy herself.

Though, she had to wonder if the other students from other class were stupid enough to be peeking at their classroom just to see her when they could get in trouble.

"Herbivores, what are you doing to the hallway?"

"H-hibari-san! Um...well... to take a look at the male that turned female?"

"I'll bite you to death!"

Tsuna, who could easily detect those voices even when she's in class, sighed and shook her head.

"Idiots."

...

Okay so maybe it wasn't everyday you could see a boy turned into a girl but that didn't mean they should follow her and stare whenever she move.

"Tsuna-chan!"

Someone called behind her and she turned to see a boy who used to bully her smiling at her.

She smiled politely but her mind was just screaming, 'Aren't you my bully before? Why are you smiling at me like we are friends?'

"I like you! Would you like to be my girlfriend?"

Tsuna blinked and without hesitation, she muttered a "no" before making a run for it.

'How mess up is that?! A bully confessing just 'cause I became a girl!' she thought in her mind though she didn't notice she said it aloud and her loyal right-hand managed to heard it.

"Juudaime, who said those words and did he harass you?!" Gokudera asked in panic and worry, gripping onto the female's shoulders. He already learned that his boss didn't want to be treated as a damsel-in-distress so he returned to using his previous title.

From the amount of jealous and hatred sent their way, Tsuna could just guessed that she and her storm guardian was in a relationship since she was now a girl and you got the drift, right? Since the brunette wasn't in the mood to explain at all.

"Yo, Tsuna!" Yamamoto appeared out of nowhere breaking the somehow connection of the two and let his arm lay in the female's shoulders. "What me to talk to the other boys to stop harassing you?"

Gokudera glared at that and Tsuna softly smiled in gratitude.

Though the girl wondered if she heard a threat within the tall teen's word but shrugged it off. There's no way her rain guardian could threaten someone, right?

The room seemed to tense in the atmosphere and the boy-turned-girl could only sighed again though she couldn't see why they were angry at her.

It seemed like the thought of them thinking something was happening with her and Yamamoto was escaping her oblivious mind.

"Omnivore," Hibari glared furiously and made a grand entrance of jumping in front of her. "I'll bite you to death!"

The glare and intensity increased and Tsuna could feel raw hatred and jealousy from the other girls and some boys.

'Now, that's mess up! I get to be hit and they get angry at me?!' she thought, thanking the gods that she had a head start to run from the perfect. 'Why is Hibari-san even angry at me?!'

It never occurred to her that maybe the girls and some boys who liked Hibari was jealous at her from getting his attention and the prefect calling her "omnivore" when it was usually herbivore.

And it didn't occur to her that the perfect remembered how she fought with him yesterday and was giving his revenge.

...

"So Tsuna-chan, what doe it like to change into a girl after being boy since birth?" one of the girls in her class had once asked quietly during their science time and it had come to the point that everyone just forgot the lesson to listen to the conversation. The brunette didn't really like the attention but hey, at least, they weren't listening to a complicated lesson now.

She just couldn't believe that their teacher didn't end up bitching at the actions. Nezu-sensei was after all a scary and bitchy teacher. She really needed to stop sounding a bit like Xanxus with all the cursing.

"Well, it's weird and awkward," yup, that's the only thing to summarize her experience without using colorful words. She blushed slightly when everyone turned their attention to her. "I mean, I was a boy and I have a crush already then I just turned into a girl... I can't think of the same way and then, there's the girl stuffs that I gotta experience!"

"True, true," the boys echoed easily, tying up their...teacher?! Then, they paused, grinning like they just hit jackpot. Tsuna didn't know why but she wished she'd be in the rope instead of the sensei who struggled to get out of the bound and was glaring rather heatedly at her. She pouted. She didn't even do anything to the man.

Though, she had to question why the old male had to be tied up.

"Wait, did you just said you experience what girls normally experience?"

"Yeah," the mafia boss briefly noticed how the girls seemed to emit dark auras like they would kill if another word from the guys were heard.

Then, the males, excluding Yamamoto and Gokudera, laughed at loud and pointed at the boy-turned-girl. "Then, you got your first period! HAHA! Dame-Tsuna's a woman now!" they teased, having tears and their stomach aching from laughing. "You can get pregnant!"

Blink once, twice, thrice, then...

"HIEEEEE!"

Yup, the brown eyed female didn't think of that possibility but now, that someone mentioned it.

"What if this was actually permanent? What if I'm actually going to leave like a girl now?" the thought really teared her up that the girls furiously glared at the insensitive males. "I don't want to stay as a girl when my heart's a male!"

"Tsuna-kun," Kyoko had called out softly, wiping the tears on her round eyes and she was really glad for the male honorifics. "I'm sure you're going to turn back to normal. You won't stay as a girl. I'm sure of it."

And that was a start of such a beautiful friendship between the girls. Though, some people would think of it as something more than friendship considering the boy-turned-girl had a crush on the girl when she was a boy.

Tsuna's life as a girl was really plain weird and awkward.

...

Tsuna sighed and fell on her bed in exhaustion.

After her breakthrough, there were then spreading rumors about her being a relationship with Gokudera, Yamamoto, Hibari, Ryohei, Enma, Hana, Kyoko, and Chrome!

And boy was she angry! She can understand the two first since she was always together with them but Hibari, Ryohei, Enma, Hana, Kyoko, and Chrome?

She's a girl now and clearly not going to be in relation with girls until she got back to normal and god! She was straight! Okay, for better answer, she was asexual for now until she got back to being a boy who liked girls!

And another note, Enma was not even in school. Hana was not even nice to her before. Ryohei treated her like a younger sibling. Hibari was just Hibari. And Chrome treated her like a boss.

...okay, maybe Chrome's reason was bad, so bad but Tsuna couldn't think of another reason for now.

Anyway...

"What are you doing?" the brunette narrowed her eyes at big luggage that she saw and felt she should be prepare for something.

Reborn smirked at her devilishly.

"We're going to Italy."

"Ah, okay," she nodded absentmindedly and then froze up in realization. "WHAT?!"

"To visit Xanxus and the Varia and also some others and they'll meet you as a girl."

Thud.

Ah. Even with her previous warning, Tsuna still couldn't be prepared for that.

...
