The sun was setting. A lone high school girl was running slowly down the slightly darkened path while clutching her bag in front of her chest. The girl had an odd pineapple hairstyle with the same purple colour as her eyes. She occasionally glanced at her watch which at the time showed fifteen past six. 'Brother will get mad again,' the girl thought to herself as she started to quicken her pace.

Just as she quickened her speed, she came to an abrupt stop and turned around to see her behind. There was no one or nothing that caught her attention. As she saw this, the girl tilted her head in a confused manner with her permanent poker face and thought, 'I'm sure I sensed someone a while ago. But, if there really is someone, then I better go back fast.' With that, she continued her way back home, unnoticing a pair of eyes which was watching her move.

About fifteen minutes later, the girl arrived in front of four stories apartment. She entered and took the stairs to the second floor. She walked to the door in the farthest end and was about to open it when the door opened from inside and a man came out. The man was about 180 cm high which overwhelm the girl for about 25 cm. He had the same hairstyle as the girl, only with blue colour and his was a bit shorter. He was wearing a white shirt and a black leather pant under a pink-but-fortunately-not-frilly-yet-regrettably-had-bunnies-on-it apron. He crossed his arm in front of his chest and glared at the girl, which would look intimidating if not for the obvious worries that his face showed and his pink apron. The girl looked down at her shoes, which could be interpreted as a sign of guilt or a weak attempt to ignore the sight before her.

"So, would you mind explaining why you are late, Chrome?" the man asked.

"I'm sorry, brother," Chrome said in a low tone while still looking down.

"I believe I asked why, which should be answered with cause. Once again, why are you late?" he asked in a higher tone which made those bunnies seemed slightly scary.

Chrome seemed unaffected by this as she slowly looked up with a puppy eyes and started a staring contest with her brother which she won under thirty seconds.

The man sighed and said, "Fine, I'll let it pass today. Are you sure it's something you can handle by yourself?"

Chrome nodded and the man sighed again.

"Okay. Come inside, then. I will serve the dinner, you can go ahead and take a bath," he said as he step back and gave a room for Chrome to enter. As she took off her shoes and her brother returned to the kitchen, her brother mumbled, "I'll survive that stare one day…"

The inside of the apartment was quite ordinary. Right from the entrance was the living room. Further ahead was the kitchen which also serves as dining room. To the right of the kitchen there was a small path with three doors with the middle one leading to the bathroom and the other two to the bedrooms. Further ahead from the kitchen was a door to the balcony.

Chrome took the first door to the bedroom to enter her bedroom. The size of her room was only about 3x3 m. Her room's wall and ceiling was painted in a light indigo colour and it only had few furnitures, which was a single person bed, a wardrobe, a bookshelf, a desk, and a chair. She dropped her bag on the chair and took out a pyjama from her wardrobe. Then she exited her room and entered bathroom.

By the time Chrome was finished taking a bath, dinner was already served and her brother was already sitting in the dining room. Chrome took her seat in front of him and as he was about to speak, his phone rang. Her brother looked at the caller's name and clicked his tongue in annoyance before he picked it up.

"Mukuro speaking," he said.

'Ah, good. I thought you won't answer this. Do you have time to listen to my request?' the other side said.

"I do, but what if I don't want to?"

'It's not a matter of want or not, Mukuro. You will do so as I said and I know you can't say no. Or if you prefer it, you can call me back after you finished dinner with your beloved little sister.'

Mukuro raised an eyebrow at the man's statement. "And how exactly do you know that?" he asked.

'I have my mean,' the man said. Mukuro could feel a smirk in his voice. 'For now, farewell,' the man continued.

"Very well," Mukuro said as he ended the connection and faced his sister who was waiting for him to finish.

"It was one of my colleagues, job matters," Mukuro answered the unvoiced question. Chrome nodded at this though she knew he wasn't telling her the entire truth. And Mukuro knew that Chrome knew this. The rest of the dinner went normally as normal as a dinner between Mukuro and Chrome could be.

Right after Mukuro finished his dinner, he stood up and said, "I'm going out for a bit. Don't let anyone you don't know inside while I'm gone. If anyone tries to break in, call the police straight away. Don't forget to lock the balcony's door. Oh, and it's your turn to clean the dishes." Mukuro confirmed his sister's nod after his statement and went out. Chrome was watching him go from the corner of her eyes. 'There goes his sister complex again,' she thought.

Mukuro fished out his phone and redialled the last number that phoned him.

'It's about time. Was it really necessary to go out, though?' the man on the other side of the line said as the connection connected.

"I can't and won't smoke in front of Chrome. And I might break something if I don't smoke when talking to you. Your request," Mukuro answered.

'That's cold, Mukuro. You could have asked for how I was doing or something. That's why you don't have many friends.'

"Yes, in your dream. You asked me to listen to your request, nothing more. And you didn't complain before."

'Of course I didn't. I pissed you off enough just by calling when you are supposed to enjoy your time with your only family. Wouldn't want to take another risk, would I?'

"Just get to the point, already."

'Can't we chat?'

"No. Now, spill."

There was a silence which probably was a time where the other man either pouted or sulked or killed himself or tried to wipe out humanity, but when he spoke again, his voice was clear and void of any sulky-ness. 'I'll be straight, then. You are to leave your sister for duration of two weeks. The time may vary depends on how you act. Further information will be given once you've given confirmation of your agreement which by the way has a deadline and that is tomorrow.'

"…I demand an explanation," Mukuro said in a dangerous tone.

'Oh, I got your attention? Good. Basically one of my men messed up and I need someone to replace his other matters for the moment, which is you. And you are to depart tomorrow, which mean you're going to leave your sister. It is kind of important, so I can't wait for him to recover. I need to explain things in the order of importance, you see?'

"Why is it me?"

'Because you are the only one as competent, if not more, than him.' The man sighed before he continued, 'I have other people, but they are busy with their own matters and I am forbidden to leave Japan when the total of unfinished documents in my desk is above 75 cm.'

"What would you do if I am to refuse?" Mukuro asked in a cautious tone.

'Ah, yes, I haven't thought about it yet. To be honest, I don't know. I'll think about it after you refuse.'

Mukuro thought about it. 'This guy… is unpredictable. He is harmless most of the time, but when he gets his mind into something, he can do some… extreme things. I can't leave Chrome alone. There are too many bastards out there who might cause her any harm. Yet it would be unwise to reject this man. It doesn't matter if I can leave Chrome to someone, but I don't have anyone I can trust. Then, that leaves…'

"I will agree on one condition," he said.

'I'm listening.'

"You are forbidden to leave Japan which means it is fine for you to go anywhere as long as it's within Japan, correct?"

'Yes.'

"Then I want you to keep watch of my little sister and make sure she is fine by the duration that I am gone."

There was another silence before the other man replied, 'You really need to get friends, Mukuro…'

"That can be done later. Yes or no?"

'I'd like to know why it has to be me.'

"Because I don't have anyone else I can trust and I know you will keep your words. Not to mention you are the one who told me to leave."

The man was quiet for seconds before he answered, 'I don't see a problem with that. Very well, I accept. Your airplane will depart tomorrow at eleven and I need you to get to the office at thirty past seven or earlier for the briefing.'

"Then I will see you tomorrow," Mukuro said as he distanced himself from his phone and ended the connection right when he heard a small 'sorry' from the phone. Mukuro stared at his phone and finally sighed. 'There you go, apologizing again. Now I can't get angry at you,' he thought as he slowly walked back to his room. He changed his walk to a stomp halfway when he thought, 'Why am I vulnerable against those types anyway?!'

.

In a dimly lit office room, there was two well-dressed man. The smaller one was talking on the phone while he walked around in the room and the other man was waiting patiently for his friend to finish. When the smaller one was finished talking, the other one asked, "How did it go?"

The man smiled weakly and said, "He took the bait. But I still feel uneasy for not telling the truth to him."

"But what you told him wasn't a lie, either. And we agreed we will lessen his sister complex or get closer to the target first before telling him."

The smaller man collapsed to his chair and sighed. "Agreeing with it doesn't make me feel less anxious. He's our friend isn't he?"

The other man smiled. "Of course he is. You decided that he is, then that mean he is. It's hard to get along with him, though."

The smaller man chuckled. "Well, that's true. But that's what makes him interesting," he said. "Oh, well, I appreciate your thought to accompany me, but you can go now. I believe it's okay to trust you to deal with him tomorrow?"

The man nodded. "Yes, there is no need to worry. But really, your acting skill is top notch," the man said. Afterward, he saluted the smaller man and leaved the room.

'Top notch, huh? So that's what other people think. I don't know if I'll be able to keep it around her, though. Well, I could try it. Then again, why do I feel like I'm taking the hard way around? But it seems interesting… Oh, well, I'm bored with the normal way, anyway. But then again if it fails then I might have a breakdown, I heard some people suffered that. But they're only some people so it should be okay. But that can't be the only problem. People say that first love is the hardest to forget. Wouldn't it disturb my other tasks, then? But I can't afford to fail, that will break my no fail records and it's kind of unnerving…' the man got lost in thought as he thought of everything that came into his mind.

.

"So you won't be home for about two weeks?" Chrome asked her brother as she stood in the doorway of her brother's bedroom.

"Yes. I will tell you the exact time once I know. But it should be only about two weeks."

"Okay," Chrome said.

Mukuro stopped at whatever he was doing and stared at his sister. "You're okay with that?" he asked. Chrome simply nodded just like usual and this made Mukuro sigh for some reason. "Are you sure you aren't just setting your nod reaction to auto?"

To Mukuro's surprise, Chrome shook her head. "No, brother, it's okay. I'm sixteen now and I can take care of myself quite well. And I wouldn't want to interrupt with your work." 'Besides, unlike you, I don't have a brother complex,' she continued in her head.

They had another staring contest which obviously was won by Chrome. Mukuro heaved another sigh for the umpteenth time in that day and said, "Fine. But if anything happens, you are to call me, understood?"

Chrome nodded again and flashed a rare smile. "You also take care over there, brother." After she said that, she left her brother's room, leaving her brother in a frozen state.

.

The next morning, when Chrome woke up, his brother was already gone. Breakfast was already served in the table along with a note that said, 'since I won't be home for two weeks, I cooked today's breakfast. P.s. if someone laid a hand on you, make sure you tell me!'

Chrome did whatever she did before she went to school (A/N: I'm sorry, I'm too lazy to write the details at this point). She then exited and locked the apartment's door before she walked down the stairs.

Chrome was halfway to the school when a boy called out to her from behind. "Excuse me, are you a student of Namimori High school?" the boy asked.

Chrome turned around to come face to face with a boy around her age with brown gravity-defying hair. His height didn't differ much from Chrome's and he wore a boy uniform of the school Chrome went to. Despite his young appearances, not to mention he's short, he had an aura that said I-have-more-experiences-than-you-people-do-so-show-some-respects-bastards even though he himself didn't seem to realize it. It might have been set to auto without him noticing.

Chrome made a quick inspection on him and decided that there was a low probability that the boy before her was one of those dirty-bastards-who-take-advantages-of-little-girls-being-alone-and-deserve-to-dies. "I haven't seen you around here before. You are a transfer student?" Chrome asked.

The boy smiled and said, "Ah, yes, I had some problems so I moved here since a family of mine lives in this area."

Chrome nodded. "Do you need something from me?"

The boy got slightly nervous. "Uh, I was wondering if you can take me to the school. I'm new here and I haven't quite used to the place yet. Truthfully, I have been wandering for about half an hour, and I can't find the school…"

Chrome blinked. Twice. 'This boy is either a total failure at picking up girls or he is a complete idiot. Namimori isn't even that big and he got lost trying to go to school! The neighbour's cat is better than him! Okay, I need to calm down. It's not like me to freak out about something. First, accept that he is an idiot. Second, help him. Okay,' she thought, still keeping her face as calm as ever.

"Excuse me, you have been silent for a while. Are you okay?" the boy asked.

"I'm sorry, I'm okay. If you want, you can tag along with me."

The boy's face lighted up and he smiled. "Thanks!"

They were walking again when Chrome unexpectedly broke the silence. "Chrome Dokuro," she said.

"Eh?" the boy asked as he turned to look at Chrome.

"Chrome Dokuro, that's my name." She turned to look at the boy. "What's yours?"

The boy smiled. "It's Sawada Tsunayoshi. Nice to meet you, Chrome."

A/N: I'm sorry for everything you may find at any part above this one. I need to change the character a bit for the story progress and I'm sorry for that. This brain of mine could not manage to make a story without ruining the original character and I'm also sorry for that. Then, I don't think this story is good enough and for that I'm sorry as well. Besides that, I'm going to make a continuation of this and because of that, I'm sorry. I'm sure if you have read until this line you must have sacrificed time which cannot be taken back for this story, I'm really sorry. I'm also well aware that I must have made some mistakes in the grammar, sorry. Mom, dad, if you read this, I'm sorry. Brother, go die. Okay, that was a joke, please ignore that.

This is my first work here so I would really appreciate it if you would give me an opinion about my story. I'm sorry if that sounds demanding. The idea for this story just pops out one day (I think it was when I was taking a dump). Since I adore 2796 and I don't like the idea of making the dame version of Tsuna to go chasing after Chrome, I made him like above. Originally I only planned to change Tsuna and sprinkle a bit of sister complex on Mukuro, but as I am not skilful enough, it resulted to what you've read above and I can't slip Mukuro's laugh anywhere, I'm sorry.

I will post the next chapter once I'm done with it, which should be a week at most. If there are no news from me passes that duration, then either I am dead or I buried myself alive for my failure. Or I'm just slacking off. Thank you.
