1 Attack on the Soul Society

"It is time to make my presence known...", Mizukai states as he slowly approaches the entrance gate of the soul society.

The Soul Society was a place where external souls resided. If a person of good intentions were to die in the World of the Living, or the mortal world, they would be sent over to the Soul Society to live their eternal afterlife. The Soul Society is split up into two parts, the Rukongai , or Rukon District, where casual souls that had died in the World of the Living resided, and the Seireitei, which was the center of the Soul Society and where all the Soul Reapers that overlook the Soul Society and protect and maintain balance within the World of the Living. Mizukai had managed to make it through the Rukon District to the entrance gate of the Seireitei with no effort whatsoever.

"Only two guards to keep watch of this gate? How pathetic." With a simple raise of his hand, Mizukai blasted away the entire entrance along with the two guards guarding it.

Every soul reaper in the Soul Society was alerted by this massive explosion within the Seireitei. All 13 Court Guard captains, which were the 13 strongest and highest ranked soul reapers of the Soul Society almost instantaneously came together to the meeting room where the head captain, the highest ranked soul reaper in the Soul Society, stood among them. The head captain, Shunsui Kyouraku, looked upon all of the captains in front of him.

"As you all have noticed, an intruder has broken into the Soul Society and by the size of his spiritual pressure, he is not than can be simply cast aside." Head Captain Kyouraku stated towards all the captains.

One's spiritual pressure is a gauge on their level of power, or spirit energy. Mizukai held an obviously impressive level of spirit energy which even exceeded the captains' level of energy.

"I have never been one for total organization in battle like old man Yamamoto was, so I leave you all with this, deal with the intruder as you please...just don't make a mess within the Seireitei." With that comment, all the captains scattered, vanishing instantaneously.

"Old man Yamamoto", or otherwise known as Genryusai Yamamoto was the previous Head Captain of the Soul Society. After a large-scale war in the past occurring in the Soul Society, Genryusai Yamamoto was killed in action after giving everything he had to stop an enemy that had threatened to destroy their society.

Mizukai continued to casually stroll the Soul Society as if it were his own. Only 10 minutes had past since he had broken in and he already had the blood of hundreds on his hands. He suddenly stopped moving as if he had felt the presence of something or someone approaching him. Right on cue, out of thin air, one of the captains appeared before Mizukai. Standing with pride, black hair falling down past her waist, with nothing but a serious expression on her face, she faced Mizukai.

"This is as far as you go intruder! You are faced with the Captain of Squad 13, Rukia Kuchiki." she exclaimed with pride.

"Ah yes, you, Rukia Kuchiki, Captain of Squad 13, sister of the famed Byakuya Kuchiki, and friend of Ichigo Kurosaki." Mizukai commented with a sense of interest.

"How could he know who I am? Many people do know of me because I am a Kuchiki and because I am a part of the 13 court guards, but he seems to know me so vividly...as if we've met before?" Rukia wondered to herself.

As if reading Rukia's mind, Mizukai replied, " It troubles you that I seem to know you so well doesn't it? Well...you will soon come to realize why...after I have struck you down!"

With that, Mizukai was behind Rukia in an instant, it was so fast it was as if he was there from the start. A large cut appeared at Rukia's side. Holding on to the gash now opened on her side, she immediately turned around to find Mizukai.

"You appear to be quite slow if you couldn't dodge that attack Mrs. Kuchiki" Mizukai said with a smile.

Shaking off the pain, Rukia pulled out her Zanpakuto, which was a blade all Soul Reapers carried with them to use in combat. These blades were a soul reaper's pillar of strength, they held incredible powers and abilities, and were weapons that defined the soul reapers. Immediately, she dashed at Mizukai as fast as she could with intent to slash him across his chest. Before her blade even reached his body, Mizukai raised his hand and stopped her entire blade with only his finger.

"Please tell me you're not this weak." Mizukai commented as he pushed her back.

"There is something familiar here, I know it!" Rukia started to think. "His blackish-brown hair, his brown, deceiving eyes, that sly smile...I've seen it all before...and not from something good."

She snapped out of it as soon as Mizukai began to raise his hand in her direction. "I have to be on guard for anything, he is on a level I haven't seen since Ichigo!" she stated.

" ...Hado number 31...Red Flame Cannon..." Mizukai said plainly.

For an instant, Rukia thought, "This is only Hado #31, this isn't a problem."

Then a blast almost as large as a building came out of Mizukai's palm. Rukia realized the situation she was in now and shouted, "Dance, Sode no Shirayuki!" with that her zanpakuto's shikai awakened, which is the first upgraded form of a soul reaper's zanpakuto.

Rukia put as much power as she could into her blade and shouted once more, " Tsugi no mai...Hakuren!", which shot a huge blast of ice toward the blast, allowing for her to cancel out the blast with her own.

"Impressive" Mizukai said to Rukia with a sly smile.

Then, with no hesitation Rukia shouted, "Hakka no Togame!", awakening her zanpakuto's bankai, which is the final and strongest evolved form of a soul reaper's zanpakuto.

Right before her bankai awakened, Mizukai pulled out his blade in front of her eyes and right before Rukia's bankai took it's form, she saw the gleam of Mizukai's blade as he pulled it out of its sheath. With Rukia's bankai activated, the entire area she was in began to fill with mist.

"I might not want to get touched by this..." Mizukai guessed as he observed the rising mist.

As the mist covered the entire area, everything within the mist turned to ice, reaching a temperature below absolute zero. Due to the speed at which the mist suddenly appeared Mizukai found he couldn't run, and in turn, his body slowly began to turn to pure ice. After a few seconds, Mizukai's entire body was frozen. Every fiber of his body, from his skin to the tiniest atom, and then his body shattered into a million pieces. With Rukia's bankai, her herself is also frozen along with everything in the vicinity, so in order to release her bankai, Rukia had to slowly take her time to thaw her body, as the slightest mistake in doing so could kill her. After some time Rukia fully thawed and left the entire scene encased in ice. "It's done" she said reassuringly.

"You believe you have won...interesting." A voice said from behind her.

She turned around as fast as she could and she was met with a blade that slashed right down her chest. As she fell to the ground she thought, "This spiritual pressure...I am certain now...this man here...is the son of Sosuke Aizen." She fell to the ground, blood slowly spilling on the floor. "Dammit, I should've known from the very start by your appearance and your actions." she muttered as her blood slowly began to stain the yellow tiled floor of the Soul Society.

"By that response, I guess that you have deduced who I am." Mizukai said to her.

"Why...How...When?" Rukia said desperately trying to cling onto her consciousness.

"Well since you're on your deathbed, I'll tell you Mrs. Kuchiki. I came to right after Aizen had apparently betrayed the Soul Society. Aizen told me he saw potential within me and claimed that he would take me in. He taught me everything he knew and showed me how to think like him...how to be as smart as he was. He told me I was his trump card if things happened to go South. Before he went off for the last time to take over the Soul Society, he had me go into a tube that he said would enhance me to be even stronger than he. I've been in there since then and just recently came out of it. As you have seen, I hold the same Zanpakuto abilities as Sosuke Aizen, except mine, I would say, is far stronger...far more advanced. Finally, I have come here...to simply speak with Aizen." Mizukai finished.

Rukia could feel her consciousness fading and her eyes failing her. The last thing she could see was the back of Mizukai as he casually walked away from her with not a scratch on him. Her consciousness finally gave out on her, and she was left to die on the floor. Mizukai continued to walk down the Soul Society towards where Aizen was being held in prison. As if it were planned, all the squad captains suddenly appeared in front of Mizukai in a perfect circle surrounding him.

"Ah finally, they're finally taking me as a real threat like they should." Mizukai stated.

The first one to speak was the captain of squad 6, Byakuya Kuchiki. "I don't believe you understand who you are dealing with at this moment."

Mizukai replied with no concern whatsoever, "Oh, I know exactly what I'm dealing with Byakuya, I am dealing with the 13 court guard captains, Shunsui Kyouraku of squad 1, Soi Fon of squad 2, Roujuro Otoribashi of squad 3, Isane Kotetsu of squad 4, Shinji Hirako of squad 5, Byakuya Kuchiki of squad 6, Tetsuzaemon Iba of squad 7, Lisa Yadomaru of squad 8, Kensei Muguruma of squad 9, Toshiro Hitsugaya of squad 10, Kenpachi Zaraki of squad 11, Mayuri Kurotsuchi of squad 12, and Rukia Kuchi- oh wait, I forgot, I just killed Mrs. Kuchiki." Mizukai said to all the captains, and finished with his eyes on Byakuya directly.

Byakuya's eyes rose in shock for an instant, then returned to normal. "She might've not been able to stop you but we are on a much higher level then her." Byakuya said, trying to shake the previous information he just received off.

"You pass your sister off as if you don't care Byakuya...but I can see the shock, fear, and worry in you as clear as day." Mizukai replied. " I'm so sorry but you all are just too late, I am really not one for patience. I will be on my way now if you don't mind." Mizukai said to them casually as he pulled his zanpakuto from its sheath. The gleam of his blade shined and was made visible to each of the captains. At that, the rest of the captains pulled their blades out and prepared to strike.
