'Thoughts'

Chapter 1-Aftermath

Uchiha Itachi growled at the papers down on his desk in frustration. He glanced at the clock. 5:30. An hour later that when he usually got up. He scanned through the photographs: the victim, the vodka glass, the knife, the phone, and finally the carvings on the wall. He scowled at the message Yami Tenshi left him. 'Here is a little present to lower your self-confidence.' His empty hand curled into a tight fist. Then for the millionth time since 3:07, he read the second sentence. 'Do not underestimate me again.' Once again fort eh 10th time that minute, the Uchiha's brown creased in confusion. 'Underestimate? What the hell did that mean?'

"If you keep frowning like that, your face is going to freeze that way." came a voice from the other side of the room. Itachi rolled his eyes. He spun around in his chair towards the computer. There, some close up pictures of the murder weapon, phone, and the vodka glass stared back at him. "I don't understand," he murmured. "The assassin killed the man, fingerprints must be on the murder weapon, but they aren't. Neither is there anything on the glass. We know that Yami Tenshi called the police, then left. Once again, no fingerprints! Argh!" The investigator gripped the pictures tightly, as if trying to extract some hidden truth. No such luck.

"Haha! Hehehe!" was the reply that came from the other side of the room. Pressing his lips tightly together in annoyance, Itachi threw his pen with high speed towards the laughing man. As the pen traveled closer, the man made no movement as to catch it or duck. At the last moment, the man turned another page in his book and leaned backwards lazily. The pen hit the white wall with a smack, leaving an ugly zigzag-like line.

"Hatake Kakashi, if you don't put that perverted book away, I'm gonna go over there and shove it up your damn ass!" Any guesses to what Kakashi was reading? :)

The named man leaned his head back against the couch's armrest and sighed. With a flourish, he tucked his beloved book away and surveyed the lone on the wall. "You shouldn't ruin your Office walls like that, Itachi." The Uchiha ground his teeth together. He glared daggers at his partner. laying on his couch, in his office! Uchiha's famous "death glare" didn't seem to faze his partner at all. Instead, he laughed and gazed up at the white ceiling.

Hatake Kakashi did not look like a 29 year old man. He looked his partner's youthful age of 21. He might just have been, based on his quick movements and active body. A black mask covered the bottom portion of his face. A headband held back his odd silver hair and covered his left eye. Rumor had it that he once gotten in a terrible fight with a serial killer while trying to save his partner. His young rookie partner escaped unscathed, but Kakashi himself suffered a deep, terrible cut to that eye. It happened 4 years ago, but he still had the long, vertical scar thought he rarely showed it. Uchiha Itachi, the rookie partner, was only 17 years old at the time. Many people whispered that the Uchiha worked fervently day and night, trying to help his partner regain his sight. As an expression of this gratitude, Itachi had preformed a surgery on the man himself. Kakashi was a legend already before. Now according to legend, he now bore the Uchiha clan's unique bloodline limit: the Sharingan. Uchiha Itachi's sharingan was the Mangekyou sharingan, while Kakashi's was merely fully evolved, as was Itachi's little brother's; Sasuke. There were only two men alive other than Itachi who bore the sharingan: Hatake Kakashi and Itachi's 16 year old brother, Uchiha Sasuke.

Kakashi finally clamed down and gazed at his young partner with a bored expression his one visible eye. "Come on, Uchiha. Loosen up a bit! Try this, it's really good for your body and it's called relaxation."

"Kakashi, I can't." Itachi sank back down in his chair. He squeezed his eyes shut in an attempt to make his blurry vision clearer. "Not with a killer on the loose. Kakashi, I'm telling you right now-this is the hardest case I've ever taken! And I know that this is your hardest, also! How can you be so at ease? There is a deadly assassin in our city! People are soon going to be dying left and right. I can't allow that to happen. And look here! one murder already." Itachi took a deep breath, letting the stress seep out. "And get your shoes off the furniture!"

Kakashi dimply waited until the other calmed down. After 4 years of working with this young man, he knew all about his tempers and ugly side. "Okay, Itachi. Calm down." Clearing his throat, he sat up, swinging his legs onto the floor. From behind his back, he produced a manila folder and began flipping through it absent-mindedly As he flipped through the information, stopping only once or twice to actually glance at it, he began to speak. "Alright. At 2:27 am this morning, 45 year old Oyama Shiro was murdered in his own bar. The murder weapon: a Swiss army knife. At 2:28 am, the police receive a telephone call with no one on the other end. Approximately 2 minutes later, they arrive at the scene of the crime. 2 minutes is enough time for any criminal to escape."

At this point, Itachi broke in. This was customary, for the two of them to speak aloud the information to one another. It helped the both of them think more clearly. "there are four things the assassin touched: the vodka glass, the murder weapon, the telephone, and the door. None of these have fingerprints on them; as usual. We have had crime scene investigator's scour the whole bar from top to bottom, with no success. Also, the assassin let me message signed in the victims blood and cared into a wall. It is apparent, even without an autopsy, that the assassin used a different weapon only for that purpose. Yami Tenshi killed Oyama Shiro, and then signed the message. Simply by looking at the photographs, the wound is neat and precise. There is no indication of the knife being torn out to be used again; then replaced."

Kakashi carried on: "We cannot assume anything. Oyama Shiro had not wife, no children, no living relatives. He had been working in that bar for 25 years. It is likely he may have been giving the vodka to an appropriate customer: a man or woman over 21 years of age. On the other hand, Shiro's friends always said he had a soft spot for underage customers. They also said that he tended to become confused when rather drowsy. It was 2:27 am, very late to be awake for the average person. The vodka could have been meant for an underage or appropriate man or woman. We know that it was not for Shiro himself. The victim's fingerprints were on the handle, but there was no trace of his saliva on the rim."

Itachi sighed when the narration was complete. "So we're back to square one." Glumly, he dropped his head into his hands. "Dunrof!" he exclaimed incoherently into his palms. Kakashi's eyebrows arched. His younger partner raised his head. "Damn it." he muttered wearily.

Kakashi noted how tired his long time friend and partner looked. Bags were noticeable under the Uchiha's eyes; his sharingan was dull and bloodshot. He blinked too frequently and his cheeks were sunken in. the older man knew the only two things Itachi clung onto while keeping his sanity were his determination, and his little brother; Sasuke. He shook his head and sighed as he thought of the younger Uchiha. The Uchiha clan's massacre created a deep chasm between Itachi and his younger brother. Sasuke was only 8 at the time and the tightly-knit bond of the two brothers was torn apart. When Kakashi chose Itachi as his junior partner 4 years later, it was the perfect solution.

One of the many reasons that Hatake Kakashi was a world-wide legend was because of a special trait he possessed. He was a man who could bridge chasms-between rebellious teenager and older brother, cold-blooded criminal and police, and between illiterate and intellectual. He joyfully remembered the day when the brotherly bond was restored. This success was partly Sasuke's ability to handle his grief. His grief had unearthed a musical talent deep within him that helped him as no human had been able. He looked up to Kakashi as another older brother, though they had a tendency to annoy each other to no end sometimes. Sasuke was the pride and joy of Itachi's life; his precious person. All this had a positive side for Kakashi, also. Besides actually feeling like a part of a family, it helped with his work too. With 2 young men who were both child prodigies and now full-out geniuses, he had no trouble completing cases.

"Kakashi?" Itachi's voice interrupted his thoughts. Kakashi shook his had and came back to reality. Itachi sighed once more at the cow-eyed expression in his partner's one visible eye. He cracked a small smile. "At least we have one good lead. We now know that Yami Tenshi is in our city. And that lead lands you on an undercover job at a high school!"

The older man chuckled. He vaguely remembered 2 days ago:

FLASHBACK

"Sasuke? Sasuke! Are you listening to me?!"

"Yes, aniki." the youth answered. His eyes never left the computer screen; his fingers never slowed.

"Alright. In order to keep the assassin unaware of our actions and to gain some more leads, we have come up with an alternative solution." Here, Itachi took a deep breath, and then plunged on. "Kakashi is going to be a teacher at your high school."

"Hn."

Kakashi exchanged glances with Itachi. "Ahem, Sasuke. According to your class schedule, you are in two of my classes. I will be teaching calculus and your art/creative writing class."

"Aaa." Sasuke answered off-handedly.

Itachi's eyes narrowed. His lips pressed tight together like whenever he was annoyed. He heaved a stressed out sigh and shook his head twice. "And then I bought a pig, and painted the kitchen purple." Kakashi bit his tongue to keep from laughing. Itachi smirked and waited to hear how his younger brother would answer.

"Hn. You are working on that Dark Angel case 24/7; since when do you have time to buy a pig? What in the hell would you do with a pig, anyways? The kitchen is still white." Sasuke's fingers finally stopped. It was his turn to smirk as he looked up at his brother.

Kakashi's one eye curved upwards in a semicircle. Creases around the mouth area behind the mask indicated that he was smiling. Itachi hi blinked twice and opened and closed his mouth, but no sound came out. Kakashi laughed. "Itachi, you look a fish on dry land."

END FLASHBACK

Itachi laughed lightly, also remembering ht moment. A loud beep, beep sound of an alarm clock followed by the sound of an object hitting the wall made both men smile. Itachi glanced at the clock. 'Six o'clock already?' The Uchiha sighed good-naturedly and stood up. "Well Kakashi, it's time to wake the brat up. Come and help me?" Both men exited the spacious study. Yami Tenshi, Dark Angel, the assassin, was forgotten for now.
