Disclaimer: I do not own any BLEACH characters. If I do, BLEACH won't be the same again…

A/N: This is my first BLEACH fiction. So, please be gentle with me… and if there is something weird with my story (like something that is totally out of BLEACH), GOMEN NASAIIII! R&R!

Chapter 1: New Mission.

"Taichou! Taichou! Chotto matte kudasai!"

Kuchiki Byakuya stopped his pace and turned around, seeing his fukutaichou, Abarai Renji, was chasing after him. He let Renji to take his time for his breath came to the normal rate.

"Nan desu ka?" Byakuya asked.

Renji handed him a paper, "Take a look , Taichou. We have just given this."

Byakuya took the paper and immediately his calm raven eyes met with a pair of serene turquoise eyes. He began to examine the paper carefully. Then, his thin lips curled into an invisible smile, "How amusing…," he turned to his waiting fukutaichou, "Prepare for our next mission."

KRRIIINNNGG!

All the students of Class 2F went to their seats and their class teacher entered the room. The class leader then stood up, "Tatsu!" and all the students stood up, "Rei!" and the students bowed, saying, "Ohayo gozaimasu, sensei!"

"Ohayo, mina-san! Now, settle down while I'm going to call for attendance!" she began to call out names. Kurosaki Ichigo looked towards outside the window, Kuchiki Rukia was reading a modern-horror novel, Inoue Orihime was drawing something in her notebook, Ishida Uryuu was memorizing the mathematic formulae and Sado Yasutaro or Chad was…well, paying attention towards the teacher.

After the teacher checked the attendance list several times, she then turned her attention towards her students, "Mina-san! I'm not going to be your class teacher for a while as I am told by the principle to be in charge with Class 2A's two week trip to Kobe. So, there is a temporary teacher that will replace me for the time being. And…you will have a new classmate."

A buzz of excitement and curiousity broke out but stopped when there was a knock on the classroom door.

TOK! TOK!

"It must be them…," the teacher went to the door, "Ah…here you are."

"Hell… Rukia, I suddenly have this very bad feeling…," Ichigo said in a low tone.

"The same here…and there," Rukia motioned towards Uryuu who was closing his notebook and suddenly turned alert.

"Even Chad and Inoue…," Ichigo examined Chad became more silent and Orihime became more excited.

"Now, please come in both of you," the teacher said and every eyes now set at the door. A very familiar red-haired lad entered with such bizarre eyebrows, only now with Karakura High School's uniform not the usual black robes. A very familiar raven-haired man followed after and wearing black suit, without the kenseikan that usually used to clip his medium-length hair and the usual black robes together with the scarf. Ichigo's, Rukia's, Uryuu's, Chad's and Orihime's eyes became widen with either shock (Ichigo, Rukia, Uryuu and Chad) or delight (Orihime) expression.

"Class, welcome your new class teacher and new class mate, Kuchiki Byakuya-sensei and Abarai Renji-san. Abarai-san is transferred from Okinawa because of family business and I hope you all will help him to adjust himself to this class. Kuchiki-sensei…well, the name says it all… Rukia-san, you never tell us you actually have a brother…," and the teacher smiled.

The students all looked towards Rukia with either awe or curiousity. Ichigo, Rukia and Uryuu stood up so suddenly that their chairs fell onto the floor. Their faces were darkened that the surrounding atmosphere turned tensed.

"Nan desu ka?" the teacher asked.

The three of them pointed furiously towards Renji and Byakuya, "Y-YYYOOOUUU! THE H-HELL WHAT ARE YOU DOING HERE?!"

After some explanations and white lies, all was settled and no suspicions were flying on the air. And now, Ichigo, Rukia, Uryuu, Chad and Orihime were sitting at the living room of the rent house where the Soul Society had provided for Byakuya and Renji.

"Why are you here?" Ichigo asked.

Renji handed a picture to him, "Take a look."

Rukia, Uryuu, Chad and Orihime gathered around Ichigo to take a look at the picture. A hooded half-masked person was sitting by a lake. Even though the picture was taken a bit far, they could still see the person's eyes, the serene turquoise eyes.

"So…what?" Ichigo asked.

"Someone with shinigami's power that doesn't has reiraku (spirit thread) and managed to slip from the shinigami that the Soul Society has send to spy on it, and also has kicked some ajuukaru's asses (a type of hollows) to their bloody end," Renji replied.

"You don't explain anything," Uryuu stated.

"I agree," Rukia added, "If both of you are looking for this person, for what?"

"Well…," Renji said, "This person…is said to have few meetings with Ichimaru Gin and Tousen Kaname…"

"I can't see the point," Orihime said, "Those two might just as interested as Soul Society are interested in this person…"

"I agree with Inoue-san. This person couldn't have anything associated with the hollows since the person does 'help' shinigami to wipe out the hollows…," Chad added.

"We are thinking about letting the matter go, however… Reports say that Ichimaru and Tousen call the person…," Byakuya looked towards them, "…Aizen-sama."

"NANI?!"
