Sparks flew as the two blades clashed. Deidara had been burning with the urge to fight this opponent for quite a time since he knew him, then again, he hoped different kinds of sparks would fly between the two, now that the day was finally here he was giving it his all. Sasori eyed his 'partner' in disgust as he parried the attack that had just been launched on him, his heart was pulsing, when he met his opponent, when he got to know him, Sasori never knew that it would come to this, but in this occasion he found it only fitting that it did. Swords clashed again, with the loud sound of colliding metal, sparks rained once again over the two battling figures.

7 Months Earlier

Sasori sighed as he and his comrades embarked on the beginnings of a vengeance mission, a raid on a village to the north, that had taken many lives from Sasori's organization. Sasori's superiors had ordered that he and the several other individuals that had been assigned to the same mission, to spy on specific members of the opposing organization known as 'Shihanma' and learn their weaknesses, strengths, personality traits, even learn some of their history. They had been spying on said members of the 'Shihanma' for 3 or 4 months, which was much too long for Sasori who despised being kept waiting for things, they knew enough by now to carry out the next mission, which was to kill them in secrecy and take their emblems, badges, and uniforms, each member of Sasori's team was assigned to a specific member of the enemy organization, all of the enemies that were to be killed were in close contact with the ring leader of the 'Shihanma'.

For this certain mission, Sasori brought his most prized weapon, Tetsusuna, the weapon was sleek, long, black and lethal. It's grip was red with thin black lines curled like a snake around the red. The hand guard was in the shape of a curled up scorpion, the eyes on which were made of green emerald stone. The tail on the hand guard also served as a poison container which could have any weapon dipped in it, so long as the weapon was small enough to dip in, a needle for example. The blade was thin and lethally sharp, it was made of black iron so wasn't easily shattered, to the end of the blade it curved into an equally lethal point that was specially designed to absorb poison and be able to release it upon being driven into an enemies body. It was his prized sword because he acquired it by defeating and killing the leader of the village he betrayed several years before he joined his organization 'Akatsuki', he learned his own techniques in mastering the weight, ability, and durability of Tetsusuna.

Sasori advanced quickly, his footsteps and breath so silent that it was as if they didn't exist. He had located his target, he waited until they were in a quiet secluded place where nobody would hear him jump down but his victim. With a lick of his lips in satisfaction, he jumped down and plunged the blade into the 'Shihanma' member, killing him instantly. Blood began to pour everywhere, staining his 'Akatsuki' uniform, "Good thing Leader-sama told us to make this a disguise retrieval mission" Sasori thought to himself as he quickly pulled on the enemies uniform, leaving the corpse with a little bit of final dignity by putting his discarded shirt and pants onto him. Sasori grimaced when he thought of how much Ryo that greedy Kakuzu was going to make him pay for a new 'Akatsuki' uniform, given one of the reasons Sasori didn't like the sounds of this mission from the start was that his leader had told him and his team that if any evidence of their murders were left then to burn the clothes that had the evidence on them, Sasori thought of this as just the leader's way of getting a peek at the bodies of his comrades but nevertheless, he was not to be questioned.

Sasori lit a match and set the Akatsuki cloak alight, cursing silently at his leader while doing so for making him do that. At first he thought that his leader was insane for thinking that the 'Shihanma' would actually buy their disguises, given their faces would look nothing like the originals, that's why he was relieved to discover that the specific members that they were to assassinate wore masks to display their elite rank to those below them, a bit of a completely self centred complex, Sasori had thought, then he remembered the ego of his leader and it all suddenly made sense. The reason why his leader had picked these individuals above all the others was that they reminded him of how superior he was to them and that such egotistical scum shouldn't be allowed to live. "What a hypocritical leader we have" thought Sasori with a disapproving expression, however he could not deny that, no matter what the circumstances were, he still enjoyed killing someone with Tetsusuna for the first time in a while. When the rest of his team had successfully taken down their targets and acquired their disguises, they headed back to the 'Akatsuki' hideout.

"Did you hear?" asked one of Sasori's team-mates, "There's a newbie joining our ranks tomorrow, leader-sama says we're to put him through initiation, thinks the newbie has potential too"

Sasori looked at him puzzlingly, how could a new person be joining the Akatsuki? Wasn't there enough already, bringing random Rogue Ninja in to assist Sasori in his mission seeing as he had no partner was something enough but a new member? "What if the initiation doesn't go to plan and he doesn't join our ranks" asked Sasori, genuinely wondering about what would happen then.

"If he doesn't join our ranks…" said the temporary Akatsuki member, "Then we're under orders to eliminate him."

Sasori was intrigued by this plan, he was looking forward to the following day.
