Chapter 1: Why Can't I Have a Boyfriend!?

Nagi was definitely confused when suddenly her 'soon becoming boyfriend' guy ran away as soon as he saw her on the way to school.

WTF!?

She thought ridiculously. She just couldn't get it. She didn't understand why every boy on whom she had a crush always ran away from her after their first date. She didn't do anything wrong did she? So why the hell did they run?

She sighed. Did she have no luck in finding boyfriend or the luck-lady just hated her because she was far more beautiful than her, she didn't know.

"I wonder why I can't get a boyfriend…," she said weakly while laying her head grumpily on her desk in her classroom which was located in building A inside all-girl Midori Senior High School.

"You got dumped again?" Nagi's closest friend, Miura Haru asked her as she approached the slumping girl when they were waiting for the teacher to start the homeroom.

"What do you mean I was dumped? We even hadn't started anything yet," Nagi said. She looked up at Haru nastily, rather annoyed at her since Haru implied that she was not popular with boys.

"Well, it's always like this, that's why. You're always left alone after you went on date once with your crush," Haru pointed out the so truly true fact. Nagi threw her a dirty look. "I wonder what you did to make them afraid of you even if you're so popular among them," Haru continued while smiling pathetically at her. She sat beside Nagi while tapping her back slowly.

"That's not funny. I don't even know what I did to them. We went on date normally like we're already lovers, and when today I wanted to tell him that I liked him, he ran away as soon as he saw my face! What the hell is wrong with him?" she asked in annoyance.

That's right. She, Rokudo Nagi was a pretty girl with long straight smooth black hair. She was cool and calm, and no doubt, she was clever and diligent. Moreover, she was a daughter of Rokudo family, an old family which had a close relationship to Japanese's emperor. She was really rich and she lived like a princess. Her parents were both working. Her father was a president director of a big company and her mother was a successful actress. Both of them were really famous in Japan. Everyone knew about Rokudo family.

And…despite her awesome background and her cool beauty, she had not had any boyfriend yet.

Why you ask?

It wasn't because she was gloomy or afraid of men. She was actually talkative and popular, but it's just like she thought earlier. Either she had not had any luck to look for a boyfriend or the lady-luck just hated her in the first place. Every boy on whom she had a crush always ran away from her after their first date.

"Argh, I can't stand it anymore!" she shouted suddenly while standing, surprising Haru who was still silently sitting beside her.

"Hey, don't blow up like that," Haru said, trying to reassure her.

"Whatever, I will go home now," Nagi replied sulkily. She had been pissed off already and she would not just stand still doing nothing. She had had enough of this and she would try to find out why those boys always ran away from her.

"Hey, what about the homeroom?" Haru tried to stop Nagi for skipping class, but the other girl just didn't care anymore.

"Tell teacher I went home because I am sick," Nagi said as she snatched her bag and hurriedly left the class.

Haru just sighed seeing her friend's back before she got out from class and closed the sliding door again. "I don't know if you get detention later, Nagi-chan," she mumbled and went back to her own desk, leaving Nagi's empty desk now.

"Well, how can I start to investigate this wonder?" Nagi asked to no one in particular after she got home and changed her uniform into casual clothes, a red t-shirt and a tight black skirt. She thought for awhile before she found an idea. "I guess I can start by calling those boys and ask them why they ran."

Nagi took her cell phone and laid down on her fluffy white bed. She dialed the number and pushed the 'call' button. Then she waited until there's someone answering the phone.

"Yes, it's Yamada speaking,"

The first who was answering the phone was Yamada Ichijou. He was the son of a vice president director where Nagi's father worked. He was a nice young man who had a bright future and currently was attending college in Todai, shortened of Tokyo Daigaku, a. k. a., Tokyo University.

Nagi liked this man ever since the first time they met and her father approved it if she wanted a serious relationship with him. It seemed Yamada also liked Nagi, so she invited him to have dinner in her house.

However then, the next morning, when she wanted to ask him on a real date, he suddenly fainted when he met her, and since then, whenever she called him, he would immediately hang up on her.

Nagi sat again on her bed and then, "Yamada-san,"

Upon hearing Nagi's cheerful voice, the boy immediately paled and his hair stood up, so he quickly hang up the phone before Nagi even had chance to greet him.

Nagi was pissed off when she heard the quick 'beep-beep' sound on her phone. She felt like smashing her cell phone on the floor, but she felt 'what a waste', so she just pushed the 'no' button and sighed. "Damn, he did it again," she muttered in annoyance.

Then she tried again to call her other 'soon becoming lover' friend. This one was named Kairi Hikaru, the second crush of Nagi. He was a third year senior in her neighbor senior high school, the son of a director who became her father's rival in business.

Nagi's father thought that this was a good chance to tighten family relationship between two companies if Nagi married that boy someday, so he approved it without any objection. Moreover, this guy was really cool, who became a star of soccer in his school. Nagi was pleased when he had a positive reaction when she confessed her admiration at him.

Then she invited him to join a blind date she and her friend arranged to know each other more. They talked just fine in that date, and they even gave each other's number. However then, again, when Nagi tried to contact that senior, he ultimately hang up on her. More, she knew that he deliberately threw away his cell-phone and his number before he bought again the new ones from her friend who attended the same school as her crush. Since then he never wanted to see Nagi anymore.

Nagi just couldn't understand why he changed that fast, even if he was a gentle guy the night before. Now, she would ask him why he did that. She repeated her action, just like before and when Kairi answered the phone, Nagi spoke. "Kairi-senp-," even before she finished her words, the boy just hang up on her again.

Bastard—!

Nagi really wanted to curse that man. She gave up on him in a long sigh and then she repeated her action to her other ex-'soon becoming boyfriends' friends, but no one wanted to even hear her voice. They always hang up on her before she had a chance to speak out.

Those guys—! They really have no manner!

Nagi almost exploded in anger as she clutched her cell-phone on her hand really hard, almost crushing it. "Ah, whatever!" Nagi threw her phone on her side and got back to lay down on her bed. She sulked again for awhile before she decided that she would play to Shibuya to look for a good guy who wanted to become her boyfriend. She didn't care who it was. As long as he wouldn't run away from her after that, she would date him. She decided.

Then Nagi picked her bag and went out her room. She met her bodyguard, Chikusa and Ken on the front door.

"Where are you going, Nagi-sama?" Chikusa asked politely.

"Shibuya," Nagi replied shortly.

"You skipped school today didn't you? Your dad will be mad at you if he finds out," Ken followed right after while grinning knowingly.

"Oh, silence, Ken. I am just fed up to study at school today," she said in a pink face, rather embarrassed. Ken laughed heartily at that while Chikusa only pushed his glasses up on his nose.

"I wish you would not skip school, Nagi-sama," Chikusa said expressionlessly and spoke rationally as always.

"And I wish you would stop being so strict," Nagi replied in bored look. "I will take the car," she continued as she held out her hand, asking the key.

"Why don't we accompany you, Nagi-chan?" Ken asked while taking out the key.

"No, I want to make some friends. You will be only in the way," she said as she took the key from Ken. Then with, "I am going," she left the house to the parking area.

"Damn, she's just really cute," Ken spoke as he looked at Nagi in wide grin.

"By making friends she meant she looks for boyfriend, didn't she?" Chikusa said while thinking.

"Anyway, she would not succeed unless he approved the man she would want to date," Ken said while smiling knowingly.

"Poor of her, she doesn't even know that she is the one who makes her all ex-'soon becoming boyfriends' friends run away from her," Chikusa just closed his eyes calmly before he closed the door of Rokudo's residence.

Nagi drove her car carefully to Shibuya. Then she parked her car in a restaurant which was famous among the teenagers. She got down the car and headed to the restaurant. She ordered a glass of orange juice in the counter and looked for a boy or two who were sitting alone to hit on.

She found one. A tall boy with spiky black hair had a cheerful innocent expression on his face. His face was handsome and he had a toned body. Oh, he was just Nagi's type. Nagi pretended to look for an empty table, but there was just none, so she hit on him.

"Excuse me, is this chair occupied?" Nagi greeted the boy with a friendly smile and he looked up at her.

"Nope, you can use it," the boy smiled friendly back at him.

Nagi blushed a little upon seeing his bright smile.

He's cute.

She thought happily as she sat in front of the boy. "Are you alone?" she asked confidently with her smile which would make any man throw his self on her feet.

"Nope, I have a date with someone," the boy said surely in that same bright smile. Nagi face faulted.

Damn, he has already been dated!

She thought rather annoyed. And he was her type too. "Well, then, is it alright if I sit here? She will be jealous, you know?" she asked while smiling nervously.

"Never mind, he will not be jealous just because I sit with someone else," the boy said again confidently.

"Oh, I see…," Nagi said while smiling before she realized what she heard just now. "Eh, wait a minute," she realized. "She is a he?" now she asked while looking at the boy oddly.

"Um, he's a boy, that's why. We will go together and this is our meeting place. I am waiting for him right now," he answered in a happy grin.

"O-ou…," she said while sweat dropping.

Damn, he swings on that way…! And he's just so cool! What a waste!

Nagi thought again while crying inwardly.

"Then, are you alone?" now the boy's time to ask Nagi.

"Yeah, well, I have just been left by my (soon becoming-in Nagi's thought) boyfriend, so…," she answered, a bit down.

"Oh, I am sorry to hear that," the boy said in frowned face. "But you can just find the new one! There are still a lot of men on the surface of earth," he continued while smiling again now.

What a positive thinking guy….

Nagi thought again. More sweat dropped. "Yeah, sure," she said, pretending to laugh funnily.

"Hey, what's your name?" the boy asked suddenly, changing the subject completely.

"Eh, um…Nagi, Rokudo Nagi," she answered shyly.

"I see, Nagi-chan, eh? That's a cute name," he complimented it. Nagi blushed slightly. "I am Yamamoto Takeshi. Nice to meet you, Nagi-chan," he confidently introduced himself while pointing at his face with his thumb.

Nagi laughed slightly when she heard that. She looked happy seeing this Yamamoto's easy going personality. She felt at ease when she talked to him. They talked some more before suddenly Yamamoto stood.

"Gokudera!" he called someone while waving his hand. His face turned more brightly. Nagi was really surprised when she saw that.

Whoa, 100 percent brighter happy face! He looks really-really cheery. Who is this Gokudera?

Nagi thought in wonder. Yamamoto had been already cheerful, but when he saw this Gokudera-guy, he became even more cheery. His expression was as if he were looking at his lover…. Ok, it might be his lover.

Nagi turned her head slowly to the direction of this Gokudera guy behind her. Then she was greeted by an annoyed looking boy with silver hair, shaped like an octopus legs, and he had beautiful green eyes, just like a colour of emerald.

Oh, WOW! He's HOT!

Nagi squealed inside her mind, but she tried to remained clam outside, though…she blushed slightly at that. Well, couldn't be helped. This Gokudera boy was really-really handsome. It's different kind of handsome compared to Yamamoto, but she was sure that every girl would kill only to be his girlfriend.

"Don't shout at me like that, you-baseball idiot!—and stop waving around!" Gokudera said at Yamamoto, irritated. He didn't realize that Nagi was sitting in front of his boyfriend until she yelped a little, hearing Gokudera's harsh and strong voice.

"Hn?" Gokudera lowered his gaze and looked at Nagi's eyes exactly. Nagi looked at him in surprise. "What's with this girl?" he asked while raising his eyebrows and then he looked at Yamamoto.

"Ah, he's my friend, Gokudera. We have just met, but she's surprisingly funny," Yamamoto grinned.

"Hn…," Gokudera narrowed his eyes at Yamamoto, but the other boy only countered it with his cheerful smile. Then Gokudera looked at Nagi…, not. He glared at her with his eyes, making Nagi pale. "You're trying to hit on him, right?" Gokudera smirked.

"Oh, n-no!" Nagi said quickly in stuttering voice. "I only looked for an empty chair, and it happened that the chair was in front Yamamoto-san," she tried to explain.

"Yeah, it's a coincidence, Gokudera," Yamamoto stood on her.

"I see," Gokudera said, unconvinced though. "Well, nice to meet you then, ng…"

"Nagi, Rokudo Nagi," Nagi replied hurriedly.

"Rokudo-san," Gokudera smirked at her.

"Yes, nice to meet you," Nagi stood up and then bent at him politely.

"Let's go, Yamamoto," Gokudera then spoke to Yamamoto while turning his back, asking him out.

"Ok," Yamamoto grinned. "Well, then, see you again, Nagi-chan," Yamamoto waved at Nagi.

Nagi waved back at him in small smile.

"Ah," then suddenly Yamamoto remembered something and turned his face once again at Nagi. "If you want to get a boyfriend, go to Namimori Senior High School. There're a lot of cool guys inside that school," he said again.

"I'll surely take a look," Nagi said while smiling. Then they parted.

Namimori Senior High School, eh…. That school is in the neighbour town of Midori City after Kokuyo. I heard it is an international high school, so there might be a lot of foreigners. Seem interesting. I will definitely go there later…!

Nagi thought in sweet smile. She was happy that she got a big catch today. If Yamamoto and Gokudera (even if they're gay) were that handsome, she was sure that the other boys would be handsome too. She couldn't wait to seeing them with her own eyes.

"Ah, darn it. I was too caught up in game centre! I was late to go home, now. I hope Chikusa and Ken would not be mad…!" Nagi ran to the parking area while looking at her watch. It was almost 10 p.m., and she had broken the night hour's rule. She should have been home at 9 p.m.

Then when she saw her car, suddenly there were some men came up in front of her. "Eh, what…?" she looked at those men, some holding bottles of beer in nervous look.

"Where are you going, ojou-chan (1)?" one of those men asked.

"Excuse me, but I have to hurry," Nagi tried to ignore them and walked passed them, but suddenly her arm was caught by one of those men.

"The night have just begun, why do you hurry?" the other drunk man who caught Nagi's hand asked. His breath stink alcohol and Nagi really didn't like it.

"W-what do you want?" Nagi looked at them in offended look. She felt a really bad feeling now.

"Aren't you bored playing alone, why don't you play with us a little?" and the other just freely touched her breast.

"WAAH, NO!" Nagi's hand reacted in reflect and smacked the man's cheek hard.

"Hahaha, she's incredibly cute!" the other looked at her with predatory eyes as if they wanted to eat her alive.

"No, stop…! Someone…HELP!" Nagi screamed as those bastards wanted to do something inappropriate to her. She shut her eyes and prayed to whoever came to save her.

"Ha—h, here I thought I could sleep peacefully tonight."

Suddenly Nagi heard someone spoke.

Eh?

"Even if I've worked hard on chasing out every bug that became a hindrance, now you've ruined my resting time again, stupid girl."

The voice…. Where does it come from?

Nagi thought wonderingly even if she realized it was not the time to think like that. She was in a pinch. If she didn't do anything, she surely would be damned. Still, she couldn't help but wonder. The voice was really close to her, and it was as if the time stopped.

"You're really troublesome girl."

Then a blur of red eyes came into Nagi's vision as she suddenly fell.

EH!?

Nagi was really surprised. She didn't know why she fell. Heck, how could she fall if she was on the flat ground? Still, she really fell, deeply-deeply in the darkness.

"I hate coming out when you're still conscious. I wish you didn't have to know that I exist," that mysterious low beautiful reassuring tenor voice spoke again while Nagi suddenly couldn't even move. "But, you're in a big trouble now. I suppose I have to help you since it's my body as well,"

Eh—!?

Nagi was really shocked when she realized what happened.

69962769962796692696692769962769962769962769969276996276996276996276996276996276996276996

The girl who was being held forcefully suddenly smirked.

"My, my…. old man…, you should know your place a little, you know?"

The girl's voice turned to be lower and harder as she grabbed one of the man's hands really hard, crushing and hurting him severely.

The man yelped painfully as the others looked at them, surprised at the changing of voice. Then, the girl stood, revealing herself who surprisingly became taller than those men. She threw away the men she crushed earlier and then looked at the others with her red and blue eyes.

"W-who are you!? Where do you come from!? Where's the girl!?" the others began to panic as they looked that the girl they attacked earlier was not a girl anymore. She turned to be…a MAN!

"The girl?" now the man who had red eye on the right side and blue eye on the left side, who still wore a girl clothes asked while raising his eyebrows. "Ah, if you mean Nagi, now she was sleeping inside me. Well, not really sleeping since I took control her body by force," he said while chuckling creepily.

The men in front of him paled severely as they looked at this new guy's creepy eyes and chuckle.

"Pardon my rudeness for ruining your fun. I am Rokudo Mukuro," he suddenly introduced himself. "I am sorry, but you really don't suit Nagi at all. That's why…," the man who introduced himself as Rokudo Mukuro said as he suddenly grabbed one the men on his collar with his two hands. "I will pay you for taking care of Nagi," he smiled, no, smirked again, eyes glinting dangerously in the darkness. And then—,

"GYAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA!!" the wail, the scream, the bloody murder shriek from some men were heard really loudly, colouring and tearing the darkness of the night.

69962769962796692696692769962769962769962769969276996276996276996276996276996276996276996

Nagi closed her eyes and covered her ears tightly. She didn't dare to see or to hear what happen in front of her. She could see it. It was her, but it wasn't either. She didn't understand. She didn't have control on her body right now.

Then when suddenly the voice faded out, she could hear a man spoke. "Open your eyes, you troublesome girl."

Nagi opened her eyes a little and she found a man, a really handsome man with tall slender body and black-blue hair shaped like a pineapple's leaves in front of her. The man looked at her superiorly with his different coloured eyes. Red and blue, what contrast colours. Then when she looked at her surrounding, she could only look at the darkness.

"You—?" Nagi tried to speak, but her voice came out trembling when she looked back at the man.

"It's the first time we meet like this, ne, Nagi?" the man chuckled heartily seeing her confusion.

"Who are you?" she asked eventually.

"That's rude of you for not knowing about me, even if I am always inside you," he said again, confusing the poor girl even more.

What?

Nagi thought really confused, unable to understand at all.

"Well, never mind, since this is our first meeting, I suppose I shall introduce myself first," the man said slowly, and then suddenly there's a red chair beside him.

Huh? Where the heck does that chair come from?

Nagi looked at him and the chair with wide eyes. She thought she was hallucinating, but the man just sat down on the chair calmly. He seated his two hands comfortably on his folded knees. "My name is Rokudo Mukuro," he began suddenly, forcing Nagi back from her wondering thought, "And I am your alter ego," he continued.

There's a really long brave silence before Nagi could digest the information. Then, upon understanding the meaning of that info, Nagi, "EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEH!!" shouted in a reaaaaaally shocked look.

(1) Ojou-chan: literally meaning 'young lady' but it is said more casually than 'ojou-sama'

A/N: Typical shoujo-story. Well, I know alter ego shall not change the appearance and gender, but it is KHR fandom, anything abnormal can happen here, heheh. And I make it because I think it will be interesting…. This is just the beginning…. And later it will be more interesting…. Ah, and I am sorry if there are lots of grammar mistakes, since this is un-beta-ed. So if you like it, please be kind and leave me some reviews. Thanks for reading and reviewing!
