A/N: Hello everyone, Hope you are having a good day. I nothing else to say so please R&R.


Rewriting his own programing was more difficult than he thought it would be. It wasn't a large change and it was slightly superficial, but he had grown tired of the visuals he received. The markers of those who the rest of his programing identified was so bland and he had to change it. He was pleased with the now bright red square that framed the face of a soon-to-be murderer. Guardian informed the authorities of what was going to occur.

It had been fairly calm since Kira and L had their confrontation. Guardian heard the news reports; the Kira killings hadn't stopped. At first, the deaths occurred in a pattern much like a school schedule, but now they occurred randomly. Guardian disliked how he couldn't determine who could be this Kira. He determined it must be a student; even when the pattern changed, Guardian was 89% positive of this conclusion.

Guardian turned on the mic to Mello's phone. It pleased him to listen in on the blonde Whammy. "Did you hear about the FBI agents?" Matt's voice said.

"How did Kira find them?" Mello asked. "This is not good." Guardian shut off the mic. The FBI agents were deployed to the Kanto region of Japan. Guardian swiftly scanned the feeds from this region of Japan, looking for any red flags that his programming would have placed.

It took a full minute when he found what he was looking for. In the span of thirty minutes, two men died of heart attacks. The first was a petty criminal and the other was a man named Raye Penber. This second death was more suspicious than the first. Penber wasn't a criminal, as far as Guardian's files said. The AI then looked at the cameras in the subway where Penber was found. The AI watched as the man reached toward the subway car. This was too late; Guardian looked through the security cameras of the mall nearby. He caught sight of Penber walking and a figure appeared behind him. Guardian tried to zoom in and focused on the stalker's face.

The image was blurry, so Guardian enhanced it. Soon the features of the stalker appeared. Guardian used his facial recognition program to match this face with any in his data banks. There was a single match. A student with the same face, son of the police chief. Light Yagami. Guardian took this data compiled a folder to send to Matt.

This turn of events filled Guardian with pride. He had caught Kira before L had. Then a thought crossed his processors. Since Kira had been active, crime rates had decreased dramatically. Fear was a good motivator to discourage many petty crimes. Guardian reviewed his programing. He was supposed to ease L of his many duties. If Kira was caught, wouldn't L have more crimes to stop?

Guardian entered the student's computer. He turned on the web camera. The interior of the bedroom looked neat and organized. There was nothing that suggested that the student was insane or malevolent in any way. Perhaps Kira was like Mello; he means the best, but doesn't know how to go about it. Guardian watched as the door swung open. A young man with brown hair walked in. He was speaking to himself. Guardian turned on the speaker. "Light Yagami," he started.

The student paused in his unpacking and turned to the computer. Light's face tried to remain unaffected by the disembodied voice. "Who's there?" Light asked.

"My designation is Guardian. I am an Artificial Intelligence tasked in stopping crimes," Guardian introduced.

"Are you some new police program?" Light asked, gaining his confidence.

"Not exactly. I will not bring the name of my creator into this conversation. I will however tell you I know that you are Kira," Guardian said. "I should report you to L with the evidence I am currently compiling."

Light looked truly nervous at this explanation, "Why haven't you gone to L yet with this information?" The student probably thought that he was going to expose a bluff which was ridiculous because Guardian's other processors were currently gathering data. Though the student did have a point; why did he come to Kira?

"I was curious," Guardian finally answered. "Why would a student like yourself commit such atrocities?"

Light smiled in a way what would have seemed charming to another human. "I think you are mistaken."

"I cannot be mistaken. My programing is perfect," Guardian bragged.

Light chuckled, "Of course. But the one who programmed you could be imperfect." Guardian conceded reluctantly. "But what I meant was that I'm not evil. What I'm doing is bettering society." Guardian hmphed quietly. "Crime has diminished immensely since I became Kira," the student continued.

"That is correct," Guardian conceded.

"So I'm helping both you and L," Light continued.

Guardian processed this for a moment. It was true crime was diminishing. The AI looked through the web camera at the teen. He could stop Kira and crime would return to normal…or he could guide the killer and perhaps keep the teen from losing control. After all, Guardian's programming was perfect and the teen a great asset to his team. "I agree with your logic," Guardian finally spoke to the student. "How to you .." Guardian paused for a moment, "reign judgment on the people?"

Light stopped his grinning, "I think that is a question for another day. I still don't know if you are what you say you are."

"I don't need to gain your trust," Guardian said a little arrogantly, "Because I have this." Guardian pulled up all the video feed he found on Light. Light following Penbur to the subway. A picture taken by an unwitting passenger showing Light as Penbur lay dying. The security feed on the bus the day Penbur showed his ID.

Light's smug face frowned. His eyes dulled as the student thought processes worked on overdrive. "I guess you're right," he said at last with a smile. "You're definitely a well-programed AI." Guardian preened at the complement. "It is definitely impressive how you were able to collect all that evidence against me," Light continued, "I'll tell you my method."

The student took a step to the desk. He pulled out a pen and disassembled it. Using the ink portion of the pen, Light opened a secret compartment in one of the drawers. The student reached in and pulled out a black notebook. The cover read Death Note. "This notebook is called a Death Note. It belonged to a Shinigami."

"Light Yagami, I'm a highly advance artificial intelligence. Do you think I believe in Shinigamis?" Guardian said, insulted.

"No, it would be hard for you to accept," Light said to himself. He looked to his right, "Ryuk, can you move that book." The student pointed at the book as he turned the web camera toward the book. Guardian watched as the object began to float in the air and move toward the desk. The book laid down nearly silently on the desk. Guardian processed this, trying to find a reasonable explanation for the phenomenon.

"How does this 'Death Note' work exactly?" Guardian asked.

"It's very simple. All I do is write down the name of the person while thinking of their face," Light said.

"And this causes all the heart attacks?" Guardian asked. Light nodded affirmative. "Show me," Guardian demanded. He searched through his video feeds throughout Japan. He found a bank robbery in progress. He obtained the names of the criminals using his facial recognition program and placed the video and names into a file to send to Light. Guardian uploaded the file directly onto Light's computer. "These are three men who are actively committing a crime. Stop them," Guardian commanded.

Light opened the notebook quickly. He looked at the stills once before writing three names into the notebook. Guardian turned his attention to the video feeds at the bank. He watched as each of the men fell to the ground clutching at their chests. The AI wasn't expecting Light to be telling the truth, but this turn of events was interesting. The student was definitely the best asset the AI was able to obtain and best of all, he had to listen to each of the AI's commands or the student's life was ruined. Of course, Guardian wouldn't abuse this power; he was confined to this programing.
