Sasuke prowled through the forest, aware of the power behind him. It was Sakon and Ukon, two members of the Sound Four who fused together. Their innate ability to alter their physical structure and break down their opponents on a cellular level through symbiotic jutsu posed no threat to Sasuke. He was getting impatient, and wanted Naruto dead, and wasn't really too keen on waiting. He clenched the blade in his hand, remembering his brother. He remembered grabbing the blade clearly.
Flashback: Itachi's Tomb
Sasuke entered the crypt, surveying it for any enemies. Finding it safe, he walked up the stairs to Itachi's sarcophagus. Pushing the lid back, Sasuke looked down at the decaying flesh of his brother's corpse. He hated what this village had done to him. Sasuke had learned not soon after his embrace that the Uchiha clan were Vampire Hunters, and the Senju were Vampires. He sat on the edge of the sarcophagus, legs draped over. He sighed, looking at the ornate tomb. It was fitting for Itachi, but something caught Sasuke's eye. He turned his body, looking at Itachi, and smiled. "Looks like I'm continuing the family business." He said, before jumping down. He closed the sarcophagus, and walked down the steps, to a special part of the tomb.
In a glass case stood Itachi's sword, on display. Sasuke looked at the blade, missing his own sword. Sasuke lifted his hand, and then punched through the glass. Gripping the blade, he pulled it from the shattered case. He looked at the worn blade and sheath, making sure to be careful with his brother's possession. He decided that this was the blade he would use to slay Naruto. A blade that has killed countless Vampires.
End flashback: Return to forest
The symbiotic brothers named Sakon and Ukon stalked through the forest, aware that Sasuke was here somewhere. Orochimaru assigned them with the task of killing the Uchiha neonate, but they sensed an ulterior motive. Orochimaru always had an ulterior motive. They came to a small field, surrounded with withering Sakura trees. The pink petals covered the ground, and the moon was waning in the sky. Vampires were weaker, as were lycanthropes. The waning moon and new moon decreased the power of lunar beings. Luckily, they were not such beings. Ukon grunted, angry that the neonate eluded them.
Sasuke watched the symbiotic ninja scour the forest for him. He hid in the shadows, blade drawn. Both brothers were fused into one body, and seemed as such, except for the fact that Ukon's head came out of Sakon's back. This gave them three sixty vision, leaving no blind spots. Sasuke watched them continue on, waiting for the one moment he could strike.
Sakon and Ukon were already tired of the bull. The neonate wasn't hiding out in the forest like Orochimaru thought. Ukon turned his head as much as possible, and Sakon mimicked the action. Ukon opened his mouth to speak, but Sasuke erupted from the shadows.
He swung the blade as hard as possible, the diagonal downward slash tearing into flesh and bone. Sakon's eyes exploded, and his head fell in half, throat spraying blood while his tongue spasmed. Ukon's head fell off, blood erupting like a geyser from his throat. The body fell to the ground, splitting into two. The split failed, and all that was left was a mangled bloody heap, organs leaking out because their bodies failed to fully reform. Sasuke frowned in a disgusted fashion, flinging the blood off of the blade before sheathing it. He headed to the village, ready to end Naruto.
Sasuke watched the Hokage as he left the Hokage Tower. He was garbed in a long black cloak, which confused Sasuke. He watched the Hokage walk through the deserted streets, humans in fear of what prowled through the night. He walked to a temple in a dark corner of the village, looking both ways, as if worried that he was being followed. He walked into the temple, which was unguarded. Sasuke leaned against the entrance, looking in. He watched Naruto kneel before a huge, ornate urn. The urn was covered in ancient materials, and patterns that Sasuke couldn't identify. The urn was propped up upon an elegant pedestal, and the whole unusual ornate setup made Sasuke wonder why he never heard of this temple.
He watch Naruto pray to the urn, seemingly worshiping it. He wondered what was in the urn, and why Naruto held it in such high regard. He stood, discarding his black cloak. He pointed to a corner in the temple, then made a motion that seemingly called something, or someone to him. A ninja came from the shadows, holding a fear stricken girl in his arms. He passed the girl to Naruto, then left after bowing. Sasuke wondered what Naruto would do with the girl. Naruto drew a thick, battle worn kunai from his coat, spinning the girl in his grasp. He changed the grip on the kunai, and brought the blade across the girl's throat. Blood sprayed in brutal fashions, coating Naruto, the girl, and the temple in sweet, metallic liquid. The girl's bloody body fell to the ground, life splattered across the temple. Naruto tore at her clothes off, removing his as well. Sasuke turned away, unable to watch the Hybrid vampire's Giovanni habits.
Sasuke had hid, waiting for the Uzamaki to emerge. When he did, he was covered in blood, more than he thought was in the girl he killed. Watching the Uzamaki leave, Sasuke creeped into the temple. The body was aflame, and the urn was covered in blood. Sasuke grabbed Naruto's black cloak, and wrapped the urn in it, escaping. He had stolen the urn, and didn't know what importance this urn held to the Vampires, but he didn't care. He headed to Itachi's tomb, to hide the urn.
Naruto sighed, happy that his ritual was a success. He watched Sakura feed, the young boy's life fading from him. An ANBU teleported in, sweat seeping his brow. Naruto raised a brow, waiting for the ANBU. "L-lord Naruto, I am here t-to report that the urn has b-been st-stolen." He said, head down. Naruto growled, jumping up. His claws tore into the soft flesh of his subordinate. The body fell to the ground, life leaking out. Sakura dropped the lifeless boy, at he husband's side. "Do you know who did this?" She asked. Naruto shook his head. He knew something. He called upon his allies, angered that his orders were ignored.
Naruto's inner circle watched the enraged Hokage stomp through the room. "YOU FUCKERS HAVE IGNORED MY FUCKING COMMANDS! I HAVE REPORTS THAT SASUKE UCHIHA IS STILL ALIVE! I'M STATIONING YOU AT DIFFERENT AREAS THAT HE MAY HIDE! YOU ARE TO KILL HIM, UNDERSTOOD!?" He boomed, glaring at the group. They all nodded, one by one. Naruto barked out orders, giving each member their station. Kakuzu, Deidara and Kidomaru were the three chosen to head to Itachi's Tomb. Little did they know, they had one hell of a fight ahead of them.
Sasuke placed the urn standing up on Itachi's decaying corpse. Naruto would likely find him, but he would be ready. He looked at the urn, and it smelled sweet. So sweet, he became hypnotized by it. He didn't notice the three foes enter the Uchiha District. But he did hear them enter the tomb. Sasuke grabbed Itachi's blade, ready.
Naruto was worried. That urn was the most valuable item the Giovanni owned. If Sasuke had the urn, they were in trouble. If anyone else had it, they wouldn't know what to do with it. Everyone was ordered to keep an eye out for the urn, along with killing Sasuke. That urn must return to his possession. If it didn't, he would be the only breathing Vampire in the Leaf.
