Hamuko descended down the stairs wearing her twin's uniform. Minato was silent the whole time, letting his sister do whatever she wants. A couple of moments earlier, Hamuko told her twin of her crazy plan to dress up as Minato in order to be closer to the silver haired teen that caught her attention when she visited Gekkoukan High. She bought a lot of things in order to enact her plan without even consulting her brother. She put on some eye contacts that are the same color as her twin which is grey. She even cut her hair short to match Minato's hairstyle. The blue haired boy watched his twin fussing around the house in a half amused, half bored expression. Minato loves his sister and it was fun watching her do something silly and impossible. Yeah, it's impossible. There is just no way he'd allow his sister to make a fool of herself.

"What about I'd just dye my hair?" She took out some bottles and spray cans from her bag.

"Even though you amuse me sis, you got to stop this." Minato's tone was grim. Hamuko's jaw dropped.

"Come on bro, don't be such a kill joy." The brunette continued on her task, mixing some hair dye in a bottle.

"I'm dead serious," The grey eyed grabbed the bottle his sister was holding. "I can't let you drag me into this!" Minato was always calm and composed. It was unusual to see him lose his temper. Although, the last time she saw him like this was when they were kids. One of their playmates made her cry by tearing her favourite Jack Frost doll. He was scary even for a kid. Since then, everyone was nice to her.

Hamuko's eyes are like that again. She looked terrified. The last time he was angry like this, his twin told him that he was really scary. He swore that he'd never scare his sister again which in turn made Hamuko a spoiled brat. But this time, he can't let his pride sink by dressing up as his sister.

Hamuko fell silent and sat down at the couch. Minato crossed his arm and sat next to her. They were silent for quite a while before the female twin broke it.

"You know, you really could meet a lot of cute girls at St. Anne." Hamuko grinned.

Minato rolled his eyes. What am I, a pervert?

Seeing her twin's reaction, she frowned. Now think hard, Hamuko. "My best friend, Yukari..she wears her uniform skirt so low and she gives me a lot of chocolates every day." Hamuko muttered.

She really thinks I'm some kind of pervert to easily give in to that? Minato thought to himself.

"You know, I'm not going to clean your room anymore, bro. You could also do your own laundry and cooking all you want."

"I can manage." Her twin replied calmly.

"I won't wake you in the morning then. Better buy a more effective alarm clock if you don't want to be late again." Minato is really a heavy sleeper that he always misses his alarm clock every morning. His sister became really annoyed at the continuous ringing of his alarm clock every morning that they decided that she'll be the one to wake him up instead. The older twin gulped at his sister's declaration. Better be late than be like you.

"Aqua Timez will be releasing their newest album soon. I'd buy one for you if you want to." Hamuko continues to bribe her brother. Give in now bro.

Minato shifted uncomfortably, weighing all the pros and cons on his mind. He decided to remain silent thinking that his sister would eventually just give up.

"I swear. The girls at my school are cuter and hotter than those at your school!" The brunette was now shouting at her twin's ear in frustration.

Minato snorted, "Just what are you implying?"

"I could set you up with whoever you'd like at school." The other twin smiled impishly.

"Shut up already." The irritated male began arranging his headset to his ear to shut his twin's voice. He pressed the on button of his portable player but it didn't respond. He pressed again thinking that he might have pressed it too gently. Still, the mp3 player didn't react. Oh, crap. I drained the battery last night and my charger is broken..

Hamuko watched his brother with a playful smile in her face. "Oh right, I just bought you a new charger." She went to her shopping bags and fumbled for the package that contains the charger. "Do you want to have it?"

Minato hesitated, eyeing the charger on his twin's hands. If I take it, she'll enforce me to do a trade. I can't let my guard down. "Thanks for getting it for me."

"I'd give it to you if you'd help me." The other twin said in a sing-song voice. Just like any other guy, Minato also has his weaknesses: food, music, video games and girls (the last one is Hamuko's hypothesis only).

"Hey, you bought it with my money. It's mine!"

"But, I have it now and I won't give it to you." Hamuko stuck her tongue out.

My twin could be so evil if she wants to. Darn. Minato took out his phone and dialled a number. His twin figured out the familiar number that he was dialling – their mom. Hamuko tackled her brother to thefloor, snatching the phone in the process. "Geroff me Hamuko!" Minato's back is on the floor while his sister is sitting on top of her. "You're awfully heavy."

"You're unfair! Running to mum for help." She made a 'hmph' sound and crossed her arms. "Final offer: I'll even do your homework and all the chores at home."

Minato looked at another direction pretending to not hear his sister.

"I'll buy you the latest edition of the Odin Cube video game saga."

"Just get off me or I'll push you really hard." Minato glared.

"I won't until you accept." Hamuko glared back.

The blue haired sighed, "Fine, fine. Only if you follow everything you've said." His twin hugged him and finally stood up. "I'll do it for a week."

"What? I said a month!"

"We can't keep that for too long. A week is long enough." I don't want to be a girl.

"The Odin Cube is worth more than a week's saving!"

"Don't be ridiculous!"

The twins quarrelled for almost an hour until night time arrived. Finally, Minato gave in to Hamuko's last offer which is 3 weeks. They made a contract concerning the whole agreement and both of them signed it.

"I want the Odin Cube to be handed A.S.A.P. understood?" Minato smirked.

Next day.. Early morning..

Hamuko headed to her brother's room to help him dress up with her school uniform. She is full of energy today and didn't complain even if her brother isn't doing any effort in dressing up. (Minato just stands there in front of the mirror, yawning while Hamuko is fussing over him.) She is already dressed up with Minato's Gekkoukan uniform and her hair's dyed with blue just like her twin's.

Minato surveyed himself in front of the mirror and blinked a couple of times. The contact lenses he is wearing are kind of itchy. For now, he looks exactly like his sister. He wears a brown wig and there are hairpins attached to it just like how Hamuko usually wore it. Also, he is wearing Hamuko's uniform – a yellow blazer top with the school crest on his left chest and a red tie while his black skirt is riding a few centimetres above his knee. It's a good thing that he's wearing stockings so that he could show less of his skin. He even wore a bra with pads just to make his chest look bigger. He cannot believe that he was talked to do it by his twin.

"Stop putting your hands on your pockets!" Hamuko slapped Minato's hand when he attempted to put it inside his skirt's pocket.

"Well, don't be so full of energy." The wig wearing male is obviously uncomfortable and corrected his sister's attitude. "And your hands should always be on your pockets."

"How's this?" Hamuko giggled. She leaned forward and placed her hands on her pockets. Minato looked satisfied.

"It's a good thing that you don't wear any make-up."

"Actually, I usually use a lipgloss.."

"Yuck, don't make me do that!"

"Anyway brother, you should drink this." Hamuko handed him a pill.

"What is this?"

"That's a pitch enhancing tablet. Singers drink that to enhance their voice range." She handed him a glass of water.

"Are you saying that this tablet can make my pitch high?" His twin nodded.

"At least, that's what Tanaka said on his shopping site."

Minato's look is untrusting but drank it anyway. "Well.." He blinked. "My voice is still normal, this is bull –"

"Try to raise your voice. It won't work if you're being normal."

"Fine." The brunette copy twin's eyes widened and covered his mouth with his hands in horror. This is creepy. My voice is awfully high!

The blue haired copy twin laughed hard. Minato glared. "Stop laughing!" his voice is frighteningly similar to his twin.

Gekkoukan High..

Hamuko's palms were sweaty as she neared the gate. This is my chance to be close to Sanada-senpai, don't waste this opportunity Hamuko."I should make this the best 3 weeks of my life!" A few students looked around as she said that out loud while throwing her fist in the air.

"Did I just hear his voice sound like a girl?" A girl whispered to her friend.

"You must be imagining that." The friend whispered back.

"Who cares? Were gonna be late!" The two hurried on to the campus.

Hamuko coughed. "I got to be more careful." Her tone was now low mimicking her brother. She placed her now blue headphones on her ear and played some music while walking towards her twin's classroom. Suddenly a tall guy with long shaggy dark hair appeared in front of her, blocking her way.

"Hey, you kid!" The unknown student yelled at the bewildered blue haired girl.

Even though her mp3 is blasting with music, she could hear him clearly. Hamuko gestured with her hand and pointed at herself. "Huh, m-me?"

The student's brows furrowed, revealing some lines on his forehead, and his lips curved in a frown. He looks tough and has an aura that can scare people easily. "Who else?" He grabbed Hamuko's collar roughly. "Come with me."

The girl was shocked to move and helpless as the male stranger drag her away. What kind of mess was Minato involved in! Damn you, bro!

AN: I really don't know if there is such a pill that can make your voice higher. I just cooked that up. I hope you could catch the hint of who this guy is. :D Review? :)
