A/N: Here is chapter 6 for your enjoyment. For those who didn't see it, the dream sequence from last chapter was inspired by Final Fantasy VII, when Sephiroth attacks Nibelheim. The pill was Sakura's special food from Naruto. Once again, I thank you for reading, reviewing, and favoriting this story. Enjoy.

The Demon and the Detective

Chapter 6

Uzumaki Mansion-Beika City

High school detective, Kudo Shinichi, yawned and stretched as he woke up the morning after taking the pill given to Conan from Naruto and finding himself alone in the self- proclaimed ninja assassin's house. He looked down at his naked body and smirked to himself.

"I can't believe that it actually worked," Shinichi said to himself. "I thought for sure that I was going to die after that. I'm really back."

Shinichi looked over at the coffee table that he sat at with Naruto the night before. He saw a Teitan High School uniform with a note on top. He picked it up to read it.

Good morning, Kudo-kun. I hope that you like the feeling of being in your body once again, though temporary. As you see, I have acquired a set of clothes from your closet so that you can walk around freely outside without having to be arrested for public indecency. I would advise you to visit your cute little girlfriend at the detective office in order to find a place to stay. I'm sure that you don't want your tenant to know exactly where you are. You could just tell her something like you are investigating a case that is extremely dangerous and that you are taking a small, three-day rest.

'What is this?' Shinichi thought. 'A killer is giving me dating advice?'

You will notice that with this letter, there is a sheet of paper with nine lines. On it, I want you to write the names of nine people that are closest to you. As long as you play the game, these nine people are pretty much under my protection. I will not take a job to kill any of these people. If anyone is targeting one or more of them, I will let you know before handling it myself.

One last thing; your parents are not allowed to be placed on this list. Your father isn't because of my grudge against him. I will be coming for his life in the future anyway. Your mother and I were very close, so I would go out of my way to protect her anyway. When you are done with the list and getting dressed, just leave this letter and the list on the table and leave with the large rolling suitcase by the door.

I look forward to facing off with you, Kudo Shinichi.

Uzumaki Naruto, the Kyuubi

Shinichi's eyes widened after reading and rereading the letter. "How was a he friend with my mother?" he asked aloud. "No, I can think about that later. For now I need to figure out whom to put on this list to protect. Ran, her father, and her mother are a given. The professor and Haibara are also sure to go on this list. Genta, Mitsuhiko, and Ayumi might be targeted to get to me, so they should take up the next three slots. Now for the last one. I think I will put myself down. It would nice to know who is targeting me."

With that, Shinichi wrote the names down and put on his clothes. He sat back down to think about what to do next.

'Ran is at school right now, so I should wait before going to the agency,' he thought. 'I can't go home because, as Uzumaki said, Subaru-san is staying there. I guess the professor's place is the only place to go until school gets out.'

Shinichi went toward the front door and found the large, rolling suitcase that Naruto had mentioned in the letter. On top of it was another note.

My payment to Mouri-san for the case in locating Kudo Shinichi for the retrieval of Kyuu no Ikari[1], the Uzumaki Family Sword.

Shinichi hurriedly laid the suitcase down and opened it. His eyes threatened to burst out of the sockets when he saw the contents. It was completely filled with stacks of ¥10,000 notes. He quickly shut the case and closed his eyes. He opened the case again to see that the contents were not a figment of his imagination.

"Okay," he said, taking breaths to calm himself. "I will take this to Ran's after I go see the professor. I should also call my father while I'm there."

Agasa Residence

A heavy set, Japanese man with balding white hair and glasses stood in front of a table that was covered by various machine parts, tools, and chemicals. The man was in the middle of the delicate process of mixing two highly reactive chemicals in test tubes when the doorbell rang. The suddenness of the doorbell caused him to drop more of the chemical into the other test tube than he intended, resulting in a small explosion leaving him and his work area covered in soot.

The professor grumbled to himself at being disturbed as he marched upstairs from his basement laboratory without cleaning himself off to yell at the person that dared interrupt him from his work. He got to the door and yanked it open.

"I do not want to buy any, so don't come by here again," the man said, "Especially not when I am working on an important project."

"Sorry about that, Hakase," a young, male voice said.

The professor looked up to see his young friend, Kudo Shinichi, standing at his door with his signature smirk on his face. The professor's eyes widened to the point that Shinichi thought that he would faint.

"Hold on there, Hakase," Shinichi said. "I can't have you having a heart attack right in front of me. I need to talk to you for a moment."

"Shinichi!" the professor said, finally regaining his composure. "How… Why… Come inside. We can talk more in my living room. My guest would also want to hear about how you are suddenly in your real body."

The professor led Shinichi into the house. They went into the living room where Shinichi sat on the couch while the professor made tea in the kitchen. The professor took three cups to the living room table and sat down across from Shinichi as the two waited for the third guest.

After about three minutes of waiting, the two heard footsteps coming down the stairs from the upper floors. Shinichi turned to the stairs and it was his turn to be surprised.

"Tou-san?" Shinichi asked as Yusaku entered the living room, yawning and rubbing the sleep from his eyes.

"Ah, it's good to see you son," Yusaku said sleepily. He paused for a moment before his head snapped back to Shinichi's face. "Shinichi!" he exclaimed. "What happened to you?"

"I was just about to explain," Shinichi said as his father took the seat beside him. "Better yet, what are you doing here?"

"Your mother wanted to come by and check on you. Right now, she is out shopping," Yusaku replied.

"It is a good thing you are here, Tou-san," Shinichi said. "I was planning on calling you anyway. I have something to ask you about a contract killer, codename: Kyuubi."

Yusaku's eyes widened in surprise and a hint of fear. "Whe… Where did you here that name?" he asked his son.

"From the man himself," Shinichi replied.

Yusaku sighed. "Uzumaki Naruto, also known as the Kyuubi, is one of the most dangerous if not the single most dangerous man on this planet and possibly all of the others as well," he said.

"Really?" Shinichi asked, surprised. "He was extremely polite when talking to me, even when he found out my real identity."

"That just makes him even more dangerous," Yusaku replied. "I had a small relationship with Uzumaki Naruto in the past. We met when I was doing research for my first book. He offered me information on underworld dealings to use to catch criminals and as a reference for my book. The only things I was told to do in exchange was to take care of his good friend, your mother, who I was dating at the time. He also said that I couldn't reveal his true occupation to her I any way."

"So he knew Kaa-san before you did?" Shinichi asked. "Did they date before?"

"Not at all," Yusaku replied. "He was more of an older brother or an uncle figure to your mother," Yusaku replied.

"So, you revealed his identity to her?" Shinichi asked.

"I did more than that, I'm afraid," Yusaku replied sadly. "I made a plan to have him arrested while your mother and I were on a date. She saw him in handcuffs and being escorted by a squadron of police officers. The look of betrayal on her face is what initially made me regret going forth with the plan. She refused to even look at him the entire time. It really broke him. His demeanor completely changed. He went from his normal, cheerful self to an ice cold, heartless demon. He didn't speak to anyone or react to any type of questioning as he was shipped to Los Angeles. It was there, when I was on my way to assist with the interrogation, it happened…"

"What happened?" Shinichi asked after he saw his father tremble.

"A massacre is the only way to put it," Yusaku said in a low tone. "The holding cell he was put into was blown open. He then proceeded to escape the police station, killing everyone there. It was a truly frightening sight. I had just pulled up to the station when I saw that it was on fire and people were hacked apart and thrown out the windows. The blood and burning corpses of over a hundred people that were killed by this one man haunts me to this day."

Both the professor and Shinichi shuddered at the thought of seeing so many people die right in front of them.

"Still," Yusaku continued, "That wasn't even the most frightening part. What was worse were his eyes. They were the coldest set of blue eyes that I have ever seen in my life. I thought I was going to die as I stood in front of that burning police station with this sword wielding demon walking calmly and menacingly towards me, the one that caused him to go there in the first place."

"How did you get away then?" Shinichi asked.

"He wasn't intending to kill me at that time," Yusaku said, looking up at the ceiling in thought. "He only left me a message."

Flashback

"So, Kyuubi, are you going to kill me now?" Yusaku, putting on a brave front, asked the long haired Naruto.

Yusaku shakily raised his handgun up to shoot.

"No," Naruto said in a tone, completely void of emotion as he knelt down in front of Yusaku, completely ignoring the gun at his heart. "Not yet. There are more effective ways of dealing with people like you. Why kill someone when you can break them? Why take their life when you can leave a permanent scar on their soul? Why end you here when I can let you live with the knowledge that the lives of over a hundred people here today have ended because of you?"

With that, Naruto got up and walked away, leaving behind a burning police station, over a hundred burning corpses, and a completely devastated Yusaku behind."

End Flashback

"Scar the soul?" Shinichi breathed out.

"Yes," Yusaku replied. "Even now, I nightmares that make me relive that night. It was that dream that woke me up this morning before I flew here from America, probably because it is close to the anniversary of that day. All that I can tell you, since you are already involved with this dangerous man who is even more dangerous to you since he knows your secret, is to never betray his trust. If you can capture him within the confines of whatever rules he gave you, he would probably be glad to just stay locked away."

"I see," Shinichi said. "I can see that he is dangerous; being able to kill so many people so easily and just walk away, but I have a feeling that there is a reason behind him. He doesn't seem like an evil guy at all. I want to know how he is so easily capable of doing evil things."

"I don't know, son," Yusaku said. "It is your investigation now. "I will just,"

Yusaku was cut off by the sound of a bag hitting the floor. The three men turned to the entrance to see a brown haired, grade school girl staring at Shinichi with surprise clear on her face.

"Kudo-kun," the girl said slowly. "How?"

"Welcome home, Haibara," Shinichi said with a nervous smile. "Surprise, I guess."
