This is my first Detective Conan fanfiction. Please forgive me if I made a mistake at Japanese honorifics. I tried to research them, though. so, I hope you're not confused.

I opened my eyes slowly. Bright light greeted me, but I insist on keeping them open. I wondered where am I. The last thing I remembered was two men in black. I was tied to a pole back then. They mentioned something about Shinichi and Conan... I don't exactly remember. I tried to fight them off with my karate, but as I had mentioned, I was tied. They force me to drink a pill. It tasted really bitter, but I'm too focused on the headache that suddenly attacks me.

It's really horrible, as if my head was spitting apart. My bones seems like... melting. Things got extremely hot afterwards. The two men sees my reaction and mumbled something. If I remembered correctly, they said the medicine "done it's right purpose". I suppose it means I'm going to be dead. I do feel weak. They leave me alone tied to the pole, wriggling in pain.

Suddenly, my heart beats really fast and my eyes opened as if in reflex. All I remembered next are darkness.

Here I am, now, greeting the light. I supposed this was heaven.

No, no. There's a face entering my vision. A middle-aged woman with black hair. She have brown eyes too, and her face was surrounded with blinding light. I blink several times and the light ceased a little. The background revealed to be a room or laboratory of some sort. I blinked again and the woman smiled.

'Eh! You're awake at last little girl!' the woman said. 'How are you?'

'I'm fine, thank you. Why am I here?' I asked.

'You fainted in front of my house,little girl. I took you in, since it's raining hard. You've been asleep since yesterday evening. I hope you're better now.'

'Yes. Arigato gozaimasu,' I said politely.

'Uh, why don't I prepare dinner? Rest for a while, little girl, then I'll drive you home. My name is Kimura Sayuri, better known as Professor Kimura.'

'Eh? Isn't Professor Kimura the one who was mentioned on TV a lot of time?' I asked. 'They never showed your picture, and when they did, your face are mostly covered. I almost thought you're a man!'

'Really, little girl? Isn't it good to know that I'm a woman?' Professor Kimura said.

'Uh,' I nodded. 'My name is Ran. Mouri Ran. I don't mean to be rude, Professor, but I'm 17, and "little girl" doesn't seems right.'

'17!' the professor exclaimed. 'Don't be ridiculous! The most you can be is 8. You're still a child, Ran-kun.'

'Eh? I'm sure I'm 17,' I said in confusion. 'Mouri Ran, age 17. daughter of Mouri Kogoro and Kisaki Eri, Teitan High school.'

'Mouri Kogoro? That famous detective?' Kimura asked. 'Now, if I remember correctly, I've seen his daughter several times on newspaper, with a little boy names Conan too, I suppose. But she was 17.'

'That me!' I exclaimed.

'But it's logically impossible. You couldn't go younger by 10 years, there's no drug or machines for that. If there was, I definitely will take them. Heh, it's good to be 30 again.'

'30? I though you're at least 50 year old. That'll make you 40.'

Kimura looked offended. '50? Surely, I don't look that old!'

I turned red in embarassment. 'Sorry. It's hard to determined age by looking at the face right?'

'Hmm, back to the main point. It's probably that you're imagining all this thing, Ran-kun. Maybe you're putting yourself as the meitantei's daughter?'

'No! Taking about drugs, I think I remembered some men in black giving me a pill.'

'Really?' Kimura asked, getting interested. 'I might as well get a pen and pencil to publish it into a book. Make a good fantasy indeed coming from a children your age.'

'Heh!' I complained. 'I'm completely honest! Give me a 12th grade math problem! I'm sure I can solve it!'

Kimura look at me suspiciously. 'Alright. I'll start with something easy. -a + 3b out of 3 + 2a + 5 out of 4 - 3b - 8 out of 10.'

I took out a pencil and paper and began working.

'Eh! The answer is correct!' Kimura raised an eyebrow. 'Let's try this polynomials.'

I began working again. To the professor's surprise, I got all answers correct. You see, I'm not bad at school.

'Is it true? Is it true that a girl of 7 could do such complicated polynomials?' the professor said in awe. 'Well, Ran, I think I could believe you for now, as all my questions are random. Can you give me the full detail of this drug thing?'

I told her story in excitement. 'They thought I was dead. So, there's no guards and I could run here. Anyway, if there was any, I'm sure I can protect myself with karate if no firearms are used.'

'Karate? So, it's true that you're Mouri's daughter! I heard she do karate,' Kimura said. 'Alright, so logically, if they find no body, it must be that you're alive. Then, because you had witnessed something probably illegal, they must've come after you and try to kill you. To achieve such thing, they must contact your friends and relatives to gather information about you, probably with some violence in order to kill you. And if they know your story, they must know about the illegal doings, and the organization will come after them too!'

I looked in horror. 'No! That can't be! I promised Shinichi I'll wait for him!'

'Shinichi?' the professor asked while looking at her with humor-filled eyes. Noticing the extremely familiar eyes, I scowled. 'Heh, don't be like Sonoko.'

'Sonoko? As in Suzuki Sonoko? Oh yes, you're friends with her,' the professor giggled slightly. 'Well, since you have many friends and acquaintances, it'll be hard to disguise yourself, Ran-kun. Did you have any stories to cover your lost?'

We thought for a moment. 'Can I live in your house, Sayuri-neechan?' I asked innocently. 'You could say I'm a relative whose parents are taking a trip around the world, and you're asked to take care of me. As for otou-san and Sonoko, we could invent a story about... me taking a job/school overseas.'

The professor nodded. 'That might works. I don't believe Mouri would like to take another "free-loader" don't you think?'

'Not if he doesn't know I'm his daughter,' I said while reflecting sadly.

'Well, we must invent a story then. How about... '

As we eat dinner, we discussed "Ran's life", how will it go, to the last detail. In the end, a story was made.

My name is Murukami Fumiko. My parents, Murukami Osamu and Murukami Reika was traveling around the world, with me, Fumiko following them. They decided to send me back to my hometown, Japan, so I could get a proper education. I was Sayuri's uncle's brother's niece's sister's cousin's aunt's daughter. "Fumiko" will go to Teitan grade school, first grade.

My parents had travelled throughout Europe, both south and north of America, China, Korea, New Zealand, Australia, Peru, Brazil and South Africa. They are currently traveling around Egypt, Israel and Arab. They mastered Japanese, English, German and Chinese.

I was born on October 25th, in Tokyo, Japan. I wore a round glasses so no one will realize who I really am. Sayuri-neechan cur my hair to what was it's original length when I was 7. I'm a first grader in Teitan grade school, age 7.

To my family and friends, I will be learning over-seas in Malaysia, Technical University of Malaysia, in Melaka. I won a karate scholarship and will be staying in a private dorm. Kogoro doesn't need to pay a yen, as the scholarship support it all.

'Alright. Let just hope they believe all of this,' I- or better known as Fumiko, said. 'Professor, if you don't mind, can you develop an anti-dote for that drugs?'

Kimura looked in horror. 'Did you think it was that easy? First of all, I must know all the chemicals in that pill, along with its side-effect and antidote before I could even start! Although I think the only possible way of decreasing one's age is telomerase... or is it apoptosis? But girl, if I could even find a way to cure/repair any of those possible ways, I will be rich, since that means I could cure cancer.'

I sighed. 'Does it means I'm stuck like this forever?'

'I'll do my best, don't worry. I also have some colleagues that could help me, of course, with me not revealing anything. One of them if Professor Agasa. I think he's suppose to be quite famous.'

'Professor Agasa? That's a good friend of Conan-kun... I mean Conan-san now we're in the same age,' I said quickly.

'That's enough talking. I'm going to send the letters to Mouri-san, and going to apply to Teitan grade school. You can sleep in the guest room upstair, two doors from the stairs.'

'Arigato gozaimasu, Sayuri-neechan.'
