*A Byakuya/Ichigo fanfiction set in a slight AU set after Ichigo watches Rukia disappear before him. The Sado arc has not and will not occur in this story but the 17 month gap has. Meaning this story picks up where the "Sado" arc would have started I guess if you want a reference point.

This is my first attempt at a bleach cannon type AU/AR. I hope you enjoy the ride. Please Read & Review.

Science & Faith Ch. 1 - Ichigo's Reiatsu

Byakuya was bothered by something. The noble found himself sitting in his office with thoughts wandering towards the human world, or rather a specific person in the human world. He let out a nearly inaudible sigh and his shoulders moved a fraction of a centimeter.

Renji looked over at his taicho seeing the man was distressed by something. Most people did not give Renji enough credit. They felt he was incapable of noticing detail or paying attention to minute movements. Most thought he was loud and brash and incapability of really being a fukutaicho. Renji continued to silently watch his taicho knowing that man did not think those things of him. Otherwise he would never have picked the stubborn and rather wild redhead to be his subordinate. Nor would he have allowed Renji to become his confidant and friend.

"Would you like some tea, Kuchiki Taicho?" Renji asked moving to stand up stretching his legs.

Slate grey eyes gazed into calm brown eyes and a nod of an elegant chin was noticed.

Renji nodded and headed out of the room to prepare his taicho's favorite tea.

In the small kitchenette tucked away between the taicho and fukutaicho quarters of the 6th division's main office, stood Renji carefully measuring out his tea leaves and placed them into two identical tea balls. The redhead's mind drifted to when he and Byakuya had begun this odd 'friendship'. It had been just after Byakuya had awoken in the hospital after the whole Sosuke Aizen fiasco. They had spoken in private about their true feelings towards one another and from that an understanding was reached and a friendship began to grow.

Renji continued musing as he poured hot water into two stoneware cups then added a tea ball to each cup. After a few minutes he removed the two tea balls and set them aside then headed back to the main office.

Renji returned and offered his taicho a cup of tea before taking his own cup. He paused to let his taicho take a sip before proposing his question.

"Is something on your mind, Taicho?" A calm sip of tea is taken while the redhead waits for a reply.

Byakuya turned to look at his fukutaicho. "Does it seem like something is on my mind?"

Renji nodded, "You seem troubled by something..." He waited for a moment. "Is it because of him?" He asked trying to be obvious he understood Byakuya's feelings.

A stoneware cup comes to rest calmly on a wooden table as slate grey eyes cut through Renji Abarai making his muscles tighten on reflex.

"Abarai fukutaicho-" Byakuya is interrupted by a knock on the door.

"Kuchiki taicho it's Rikichi, I have word from Captain Commander. There's been an incident." The young man's voice sounded rather shaken.

"You may enter Rikichi." Byakuya spoke taking another sip of tea.

Rikichi walked quickly into the room bowing respectfully to Byakuya and Renji before addressing his superiors. "Captain Commander has requested Kuchiki taicho and Ren- Abarai fukutaicho immediately report to the 1st Division..."He paused and thought how to relay the next part... "Kurosaki Ichigo has been assaulted by an unknown enemy and is in critical condition..."

Byakuya shunpoed out of the office.

"Thank you Rikichi." Renji said as he shunpoed away behind his taicho.

Byakuya and Renji were filled in with more information in the 1st division. They received a status report on Kurosaki Ichigo and understood he was in critical condition behind a barrier at Kisuke Urahara's shop. He'd apparently been attacked by some sort of creature at the moment the tests were inconclusive on if it had been a hollow or not. They had been tasked with guarding the human until said creature could be captured and destroyed.

The team being dispatched at the moment would consist of Kuchiki taicho, Abarai fukutaicho, Kuchiki fukutaicho and Yamada Hanataro to provide guard and medical assistance to Kisuke Urahara.

Renji, Rukia and Hanataro met at a Senkaimon and traveled to Urahara's shop to receive further information.

Byakuya was held back to receive specific privileged information from the head captain.

*-*-*-*-*-*-*-*

The group of three traveled through the senkaimon towards Urahara's shop when something attempted to enter the senkaimon.

Renji told Rukia and Hanataro to run while he stayed in the rear to see if whatever was trying to get through could get through.

Renji waited until the last moment to close the senkaimon making sure Rukia and Hanataro had gotten through safely. Just as it closed Renji caught a look at something. He stared quietly and one word came to mind, 'Arrancar?'

The senkaimon slammed shut just as whatever was trying to get inside managed to breech it.

"Abarai Fukutaicho what was that?" Hanataro asked as they stood where the senkaimon had closed.

"Renji... whatever that was... it managed to infiltrate the senkaimon." Rukia said quietly. She secretly worried for her older brother's safety since he was to travel alone to meet up with them.

"Come we must send word before Kuchiki taicho enters a senkaimon to meet us." He said ushering them up the stairs to Urahara's shop.

Just inside the shop Tessai was standing guard at the door. He nodded to each one of them in greeting before going back to monitoring the shield around the shop.

Sitting inside the main dining room of Urahara's shop was Isshin Kurosaki. The old man looked a bit shaken. His night shirt and pants drenched in blood. If it was the enemy or Ichigo's was anyone's guess. The three approaching shinigami felt it was the later. Each one silently praying Ichigo was still alive.

Renji informed Tessai of their near attack in the senkaimon and informed Tessai he would tell Urahara this information.

Tessai went to inform Seireitei of this near infiltration.

Ten minutes after their arrival chills shot up the three shinigamis' spines as a deafening seemingly inhuman scream ripped through the shop followed by a surge of reiatsu.

Isshin shot up to go back into the shop but was held back by Yoruichi.

"Isshin there's nothing you can do... We have to wait..." She said holding the older man from the door.

A few minutes later the screams died down and Kisuke Urahara walked out of a room.

"Ah, Yamada kun come I could use you're expertise." The blond said motioning for Hanataro to follow him back into the room. "I will brief you all once we get him to sleep."

Twenty minutes and three more traumatizing screams later Urahara immerged from the room with Hanataro close behind looking rather disturbed.

Urahara allowed Hanataro to sit down before taking a seat himself. "He's finally asleep. I'll begin the de-" he paused as Tessai opened a door allowing Byakuya Kuchiki into the room.

"Ah Kuchiki taicho, I was just about to brief everyone on the situation at hand. Please have a seat." Kisuke motioned towards a pillow.

Byakuya sat down and Kisuke began.

"Last night Kurosaki Ichigo was attacked and brutalized by some sort of creature. It is unclear do to the dissociated reiatsu patters for us to tell exactly what the creature was at this time. We have also been unable to physically confirm that what's been trying to get into the shop after Ichigo is the same creature or another from the same group."

"Something's been trying to get into the shop?" Rukia asked remembering the creature in the senkaimon.

"Yes," Urahara replied pulling out his fan and fanning himself. "Whatever it is has tried several things including opening some sort of portal similar to a garganta before we erected the shield."

"Kuchiki taicho," Renji spoke in a calm tone. "Did anything approach you in the senkaimon?"

Byakuya turned to Renji, "No Abarai fukutaicho nothing like what you described occurred while I traveled through the senkaimon."

Urahara nodded, "So nothing tried to get through on Kuchiki taicho's watch but when the creatures was confronted by two fukutaichos and a seated officer it made a move... interesting."

"Were you able to stablilize his reiatsu?" Isshin asked looking towards the sealed room Ichigo was in. The image of how he found the boy less than an hour before burned in his mind still fresh and charring.

"Reiatsu?" Renji and Rukia spoke at the same time.

That twisted odd reiatsu they had felt earlier did not read like Ichigo at all. It made the two fukutaicho's worry.

Urahara nodded, "Yes among other things this creature managed to infuse some sort of strange reiatsu into Ichigo's body. His body had begun to regenerate its own reiatsu with the help of this strange reiatsu. This change is causing Ichigo tremendous amounts of pain so I with the help of Yamada kun have placed him under a sleeping kido. He will awaken by tomorrow evening sometime."

The others in the group mulled over this information.

"Isshin..." Urahara spoke after a moment. "Your son isn't seeing anyone at the moment is he?"

Isshin looked at Kisuke and shook his head. "No..."

Urahara nodded, "Samples were taken and I will perform an analysis on them." He walked over and placed a hand on Isshin's shoulders. "Come on Tessai will give you some new clothes to wear and then you can go rest with the girls for a while. I'll wake you if Ichigo's condition changes."

Isshin was reluctant to go but then he too realized his clothes were cover in blood and he'd have to change before his daughters noticed.

Urahara excused the two of them with the promise he'd return in a few minutes.

High above the small shop standing on the very top of the dome like shield an aggravated person stood. Long, thin tanned fingers brushed calmly against red painted lips as cold black eyes stared down at the shelter that encased the treasure this individual needed.

"Mi Corazon… I shall return for you…" The individual spoke calmly before placing a hand calmly in front of itself. "Saltar," and then it disappeared into nothing.
