Summary:

AU FemKyu. Renjou Yuuki had never known her father. The only clue that she had is that her father is a detective. Now a member of Class Q in the Dan Detective School, she sets on her journey to find a connection to her father as well as treading on the path that her father had taken. Ryu/FemKyu

This is my first time attempting a DSQ fanfic, so go easy on me. And I know that majority of DSQ fans out there don't feel good reading a gender switch fic, but I'm going to make the pairing Ryu/Kyu, and I don't feel comfortable writing a yaoi fic (sorry to all yaoi fans!), and so I decided to switch Kyu's gender. And since he's a girl in this fic, I'm also changing his name to something more feminine.

Chapter One: Renjou Yuuki

"Yuuki! Telephone call from Riku-kun!"

"Coming!"

A fourteen-year-old teen with dark green hair cascading down to her shoulders walked out of her bedroom before picking up the phone receiver that her mother held out to her.

"Moshi, moshi?" Renjou Yuuki spoke into the phone receiver.

Light laughter greeted her on the other end of the line which Yuuki instantly recognised as her best friend, Satochi Riku.

"Hey Yuuki. Are you free now? I need to go to the library for something."

"Yeah. Where are you now?"

"Near the bank at the First Street."

A silver-haired teen with his hair just brushing against his shoulders with blue eyes was leaning against the wall next to the bank as Yuuki arrived. Upon catching sight of his friend, Riku waved to her.

"Yuuki! Over here!"

"Sorry that I'm late!" Yuuki apologised. "So what do you want to go to the library for?"

"Just some stuff," said Riku with a grin as the two walked off, but not before Riku bumped into a elderly man wearing a trench coat with an umbrella hanging from his arm, causing him to drop the several yen notes which he was holding which scattered all over the ground.

"Hey kid! Watch where you're going!" snapped the man before bending down to pick up the yen notes.

"Sorry!" apologised Riku before bending down and helping the man to pick up the notes. Upon seeing this, Yuuki helped too.

The man frowned as he counted the yen notes in his hand before he grabbed Riku by his shirt. "Oi! There's a ten thousand yen note missing! You took it, didn't you?"

"Huh?" Riku blinked owlishly at the man. "I didn't!"

"Then it's you!" The man turned to glare at Yuuki this time.

"I didn't!"

"What's going on?" A police officer came to the scene just then, especially since the commotion had attracted a group of bystanders, all looking on with curiosity.

"Sir, I've just withdrawn some money out from the bank when these two kids bumped into me, scattering the money all over the ground. Now I'm missing a ten thousand yen note!"

"Like I'm trying to tell you!" said Yuuki, trying to explain. "We didn't take any of your money!"

A pink-haired girl with her hair tied up into two ponytails stepped out from the crowd just then, and all four turned towards her. "118 thousand yen," she stated, and the police officer and the man went, "Huh?"

"That's the amount that was scattered on the ground," explained the girl. "To be exact, 9 ten thousand bills, 5 five thousand bills, and 3 one thousand bills. Sir, please count the money."

The police officer blinked before realising that the girl was speaking to him. "Erm…okay." He took the wad of notes from the man before counting the notes carefully. "Let's see…" The police officer blinked. "That's right! That's exactly right!"

Whispers started to spread from among the crowd. "Then that means that they didn't steal it," said the girl.

Riku and Yuuki both can only stare at the girl in wonder.

"Hey wait!" snapped the man. "I just withdrew one hundred thousand yen. There can't only be 9 ten thousand yen bills."

Yuuki 'hmmed' before stepping up to the man in question, much to Riku's confusion. "Yuuki? What are you doing?" Riku started, only to stare, along with everyone else, as the girl took the umbrella hanging from the man's arm.

"What are you doing?" demanded the man.

"Just this," said Yuuki before opening the umbrella and everyone can only stare as the missing ten thousand yen bill floated gently out from the umbrella and onto the ground. The dark-haired girl then bent down and picked up the yen note before handing it to the man. "There you go. I'm glad that you've found it."

Ten minutes later, the three teenagers with one adult found themselves in an ice-cream parlour where the man had insisted on treating them to deserts as apology.

"I'm really sorry. I blew my top," said the man with a sheepish smile. "This is on me. Order whatever you want."

"Really?" said the girl who had helped both Yuuki and Riku out earlier, being seated next to Yuuki. "Then I'll have a chocolate parfait."

"How about you both?" asked the man, looking at Yuuki and Riku both.

"Well, I don't have to work today, so I guess I can have one," said Riku sheepishly. "I'll have a chocolate parfait as well."

Riku was an orphan, and since he does not have any living relatives especially since both his parents died when he was only six years old, he had been living by himself since then. He supported himself through school and daily necessities by taking on part-time jobs. Yuuki had met him as Riku lived next door to her.

"My mom is cooking dinner at home, so…" muttered Yuuki.

"Dinner's just dinner!" said the man good-naturedly. "You're a growing teen! You can have a snack, right?"

"All right," said Yuuki, giving in. "I'll have a chocolate parfait too."

"There you go!" said the man before leaning back into his seat. "I'll have to leave soon, so…"

"I'll repeat your order," said the waitress who was taking down their orders. "Three chocolate parfaits. Is that it? I'll be back in a bit."

"I'm sorry," said the man, apologising once more as the waitress walked away to get their orders. "I have to run to the station to get a ticket."

"Are you going on a trip?" asked the girl with interest.

"My daughter is getting married in Hokkaido," said the man proudly. "The money is for her." He then got up from his seat. "Well, sorry about that. I'll pay for those, so enjoy them." He then picked up his hat and left the ice-cream parlour.

"He left," said Riku, blinking owlishly.

"What should we do?" asked Yuuki, looking from one to the other.

"Thank you for waiting!" said a voice, and all three looked up to see the waitress from before at their table, handing out their chocolate parfaits. "Here you go."

"Since he paid for it, let's eat!" said the girl cheerfully, picking up a spoon.

"Right!" said Yuuki before noticing the girl looking at her. "I'm Yuuki. Renjou Yuuki. Nice to meet you."

"I'm Satochi Riku," said Riku with a smile. "We're both in our senior year in junior high. Nice to meet you."

"I'm Minami Megumi," said the girl, introducing herself. "I'm also a senior in junior high."

"Oh, we're the same age?" Riku pondered absent-mindedly. "I thought that you're older than us."

Megumi sweat-dropped. "Do I look that old?"

XXXXXX

"Deduction?" said Megumi as the trio walked down the streets that night, having carried on a conversation that had lasted the entire day.

"Yep," said Yuuki. "He didn't look like he was lying and no one else could have taken the money in that situation. That means the money must have disappeared somewhere before it hit the ground, right? The only thing that I could think of is the umbrella."

Megumi can only stare and Riku laughed. "You'd best get used to things like that if you're going to be around Yuuki," he said. "She puts things like this together by herself most of the time."

"Amazing!" said Megumi.

"Eh?" Yuuki blinked.

"You're amazing!" chirped Megumi. "I want to make deductions like that, too."

"This is the first time I heard another teen our age say something like that," said Riku with a grin before he recalled something. "By the way, how did you know how much was scattered on the ground?"

"That's because…" Megumi trailed off. "I remembered it."

"You remembered it?" Yuuki blinked. "In that split second?"

"Do you know what a 'photographic memory' is?" asked Megumi.

"What's that?" asked Riku.

"Once you see something, even if it's just for a second, you remember it," said Megumi. "I was born with that ability."

"Wow!"

Megumi blinked before turning her head towards the direction where a construction site currently was. "Someone's up there…"

"Where?" asked Riku.

"On the crane on top of the building," said Yuuki, her sharp eyes catching sight of the shadow, pointing towards the crane. "I wonder what he's doing up there?"

Megumi frowned as all three caught sight of the shadow waving a flashlight to and fro. "Doesn't he look like he's waving goodbye?" she asked.

"Goodbye…?" Riku nearly whispered, turning pale. "Don't tell me…!"

To the horrified eyes of all three, the shadow atop the crane stopped waving and fell off the crane.

"No!" Megumi nearly screamed. "He jumped!"

"No way!" Yuuki took off down the street to where the construction site was, with the other two close on her heels. As it is, they nearly got into a collision with a teen several years older than them on a bicycle.

"Sorry!" apologised Megumi before the three rushed down the street, despite the shouts of the teen riding the bicycle.

Within moments, the trio soon arrived at the entrance of the construction site. "Hey!" Yuuki called out.

"What are you guys in such a hurry for?" demanded the teen whom they had nearly collided with earlier, finally catching up with them.

"Someone jumped off the building!" Yuuki informed the teen.

"What?" The teen nearly choked before he spotted someone lying on the floor not far from them and rushed up to him. "Hey!" He then bent down to listen to his heartbeat, covering the sight of the body from the trio before he closed the eyes of the man. "Call the police."

As he moved away, the three gasped as they recognised the man lying on the ground as the same man who had treated them to chocolate parfaits just a few hours ago. "This man is…!"

"No way!" Megumi cried out.

The police was soon called for, and the construction workers questioned, with them writing down their contact information so that the police can contact them if the need arises.

Yuuki frowned as she noticed the site superintendent twitching his left eye as he wrote down his contact details. 'Huh? That is strange.'

Meanwhile, Megumi, Riku, and the teen from earlier who had introduced himself as Toyama Kintarou were surveying the crane from the ground. "It takes ten minutes to get to the top of the crane, right?" said Riku, craning his neck.

"That means they all have an alibi, right?" mused Megumi before she blinked and turned to her side to see that Yuuki is missing from her side. "Huh? Where's Yuuki-chan?"

Riku blinked and looked around before noticing Yuuki on the elevator that transports the workers up to the crane. "Oi, Yuuki! What are you doing?"

"Detective, I'm borrowing this for a while!"

"Oi!"

Ten minutes later, the elevator that transports the workers to the crane finally reached the top, much to Yuuki's relief. "This is really slow," she muttered to herself before carefully making her way across the beams to where the crane is.

"Oi, is she going to be all right?" wondered Kinta.

"That's dangerous! Get back here!" shouted the detective.

"Hey, Yuuki-chan!" called Megumi.

A strong wind blew just then, nearly causing Yuuki to fall before she managed to fall flat atop the crane, much to the relief of all those watching. "That was close," she muttered before brightening up as she noticed the rubber cord tied to the crane and crawled over to the spot where the cord was tied on her hands and knees. Yuuki's sharp eyes noted the ends of the cord. "I see!"

XXXXXX

And so…

"You're really going to continue searching for evidence?" asked Riku with a sigh, his hands planted on his hips as he watched his friend get down on her hands and knees searching for the evidence that she kept harping on about to the police a few hours earlier.

The crowd had scattered, and Yuuki and Riku were the only ones left, with Megu and Kinta heading back earlier.

"Yeah," said Yuuki with a nod without looking up. "I'm not giving up! There's no way that the old man killed himself!"

Riku sighed for the umpteenth time that night. "Ano sa, Yuuki," he said. "Even if you are extremely sharp and perceptive, what do you think that you can find that the police can't?"

Both blinked just then as the light of a flashlight brightened up the area where Yuuki was searching, and both looked up to see Megu standing behind them with a flashlight in her hand. "It's something small, right?" she said. "I don't know what you're looking for, but it'll be hard to find it alone. I'll help you out."

Riku sighed, shrugging his shoulders and getting down on his hands and knees as well. "I'll help out too," he said. "I've known you ever since we're kids, Yuuki. You wouldn't say and do things like this without a reason."

"This looks like fun," said a voice and everyone turned to see Kinta walking towards them. "Can I help too?"

"Thank you, both of you," said Yuuki with a grateful smile.

"Oi. What about me?" protested Riku.

"Hai, hai," said Yuuki tiredly. "Anyway, let's do it. Megu, can you shine the light over here?"

"Okay."

Yuuki scanned the brightened area closely, still on her hands and knees with Riku, with Kinta standing by Megu's side, both looking closely as well. "Tilt it a little more," said Yuuki which Megu obliged. "A little more."

Yuuki looked left and right continuously before she spotted something shining not far from her and beamed. "Found it!" she chirped.

Everyone turned towards Yuuki at the moment she said that. "You found it?" said Kinta. "Where is it?"

However, at this moment, water started splattering down on them, but Yuuki didn't take her eyes off the spot where she had found the evidence that she's searching for so desperately.

"What is this?" Megu nearly screamed. "Rain?"

"Damn! Where is it?" Riku cursed to himself.

"It'll get washed away!"

Yuuki leapt at the ground where she had seen the evidence that she had been searching for and frantically scanned the ground for it. Megu screamed before noticing where the water had been coming from and noticed through the 'rain' that the water was sprouting from a water hose aimed towards their initial direction.

"There! The water's coming from there!" said Megu, pointing one finger towards the hose.

"Damn!" Kinta cursed before he marched towards the hose with Riku by his side and grabbed the hose. "Why is a hose here?"

Riku and Kinta then headed towards the water hydrant which the hose was fixed to and turned off the water quickly.

"Was the evidence washed away?" asked Megu in dismay, soaked to the skin, along with every one of them.

Yuuki sat back on her knees, and Megu who was by her side looked at her. "Why don't you come on out?" asked Yuuki calmly. "I know you're there. He waved the flashlight in circles from the top of the building. He got people's attention and jumped off. Of course, anyone watching would think that it's a suicide, wouldn't they? Besides, once you mingled with the witnesses that ran to the site… Even if it's investigated as a murder, the slow elevator gives you a perfect way out." Yuuki got to her feet. "It was a nice trick to establish an alibi. The murderer is you, isn't it? Shinoda-san."

"Eh?" Megumi blinked.

"Shinoda?" Kinta gasped.

"The site superintendent?" Riku blinked.

"Wait a minute, I don't know what you're talking about," said the superintendent in question, walking out of the shadows. "I didn't want the employees to see the blood on the ground, so I was just going to wash it away. I didn't know that you guys are here. Besides, you saw how Nakajima jumped off, right? He pointed the flashlight towards the sky and waved it in circles. And then—"

"You said it again," said Yuuki calmly.

"Eh?"

"How do you know that he pointed the flashlight towards the sky and waved it in circles?" asked Yuuki. "He was on top of a tall building. And it was far too. To me, Megu and Riku who saw it happen from a distance, it looked like he was swinging it from side-to-side."

"That's right," said Riku, nodding.

"Yeah. That's what I saw too," said Megu.

"But you know that he pointed it towards the sky and waved it in circles," said Yuuki, looking at a paling Shinoda and walking towards him slowly. "You knew because you were the one doing it, right? There was a rubber cord tied to the top of the crane. In other words, what we saw was not a jump. It was a bungee jump, made to look like a jump to one's death! After you prepared the bungee jump, you called Nakajima-san to the roof and pushed him off. Then you climbed on the crane and waved the flashlight. So people on the ground like ourselves would know that you were going to jump. And then, you jumped off."

"I see!" Riku muttered, finally realising what Yuuki was trying to put across. "What an ingenious trick!"

Yuuki continued as if Riku had never spoken at all. "After that, you used the extra rope that you were holding to get down on the ground and cut the bungee cord. When the cord lost your weight, it snapped back to the top of the crane. Even if the rope was hanging from the crane, no one would figure it out."

"That's an interesting story," said Shinoda, beads of sweat sliding down his face, taking a few steps backwards. "But it's all based on conjecture."

"Yes," said Yuuki, nodding. "But just a little while ago, during our talk with the detective and what I've said when I went to the top of the crane, you remembered the evidence that you've left behind at the site, and tried to get rid of it by washing it away. Isn't that right?"

"Evidence? What are you talking about?"

"I found it at the very last moment," said Yuuki, and her friends looked at her. "The contact lens that fell out during the bungee jump." And she opened her clenched hand to reveal a single contact lens in the palm of her hand, and the eyes of everyone present widened.

"That's what it was!" said Kinta, his eyes nearly bulging out.

"Amazing…" whispered Megu in awe.

Riku grinned. "Not bad, Yuuki," he said.

"When you were writing down your information, you closed one of your eyes and seemed to have a hard time reading," said Yuuki. "Anyone using contact lenses knew this. It's difficult to write without one of your contact lenses. If the police examine this contact lens, a DNA test will prove that it's yours."

"It was a mistake to think of you as just another brat. I underestimated you," snarled Shinoda before whipping out a dagger from his side. "Now give it back to me!" And he dashed at the foursome.

Yuuki and Megu took several steps backwards in fear, neither one of them noticing the glint that both Riku and Kinta have in their eyes. Riku dealt a karate chop to the hand holding the dagger, causing Shinoda to drop it, and Kinta took the chance to deal a karate kick to that very same hand, causing Shinoda to nurse his wrist.

"Nice teamwork, you two!" said Megu, and Riku grinned.

"Kendo, Judo, Karate. Ten dan in all!" announced Kinta proudly. "Don't underestimate Toyama Kintarou-sama!"

"He's getting away!" shouted Riku as Shinoda took off, and the four took chase after him through the dark construction site, being slowed down a little by the beam pillars that Shinoda used to slow them down.

"Wait!" Megu called out, chasing down Shinoda before both girls saw the designer of the construction site not far from where Shinoda is. "Watch out!"

"Get out of the way!"

Much to everyone's surprise, the designer grabbed Shinoda's hand and threw him to the ground, holding him in a deep arm lock.

"O-Ouch!"

"Shinoda-san, you are accused of using your position as site superintendent to divert money and embezzle funds," announced the site designer. "Nakajima-san was the one who told the owner the truth, wasn't he?"

"I couldn't forgive him!" growled Shinoda. "He acted all righteous and ratted me out!"

"You killed him because of that?" said Yuuki.

"Detective Arai, I'll leave the rest to you," said the designer, and the four teens turned to see the detective from before walking out from behind a wall with two police officers by his sides to take Shinoda in custody.

"Shinoda Hitoshi, you're under arrest for the murder of Mr Nakajima Yoshio," announced the detective as a pair of handcuffs was snapped on his wrists. "Take him away."

"Yes sir!"

The detective then saluted the designer. "I appreciate your help with the investigation," he said. "With that, excuse me."

"Thanks to you guys, the investigation is complete," said the designer, turning towards the four teens as the siren of a police car pierced through the air. "Thank you very much."

"Um…" Megu blinked. "Who are you?"

"Oh, I'm sorry. I'm a detective hired by the owner to conduct a top secret investigation," said the designer. "I'm Katagiri Shino, a teacher at DDS."

"DDS?"

"The only detective academy in Japan where you're allowed to carry a gun? The Dan Detective School?"

Katagiri chuckled before handing a green envelope to Yuuki. "Here. Take this as my thanks for the help that you've given," she said.

"What's this?"

"It's the guide for the enrolment exam which will be held next week," said Katagiri. "Of course, it's for DDS."

"DDS?"

"The enrolment exam?" Kinta beamed.

"Try taking the exam," said Katagiri with a smile. "You guys may do pretty well."

The four exchanged looks before Riku grinned, placing one arm around Yuuki. "It's like a dream come true, huh, Yuuki?"

"Yeah."
