Hollow Infestation : Where did they come from?

Tried from the trip, the small group which embarked from hell decided to rest at a restaurant somewhere in Rukongai, as they all went there separate ways, Aoyama Sachiko stayed behind to visit an old friend, while what welcomed her was a high level hollow let loose to run wild feasting on what weak villagers there was.

It alarmed her that this hollow was not it's self, it was running wild as if lost and confused, but couldve caused this?

It didnt take long for more to appear that it would appear to be an ambush, but there was more to it, they were not there selves, if they were here to ambush,t hey wouldn't be in such a weird state, they were brought here by something else, but what could be causing this uncalled for arrivals?

Taking one hollow down, she decided to call fro backup, instead the hellbuterflies were just as confused.


"What could be triggering the beast's disorientation? " she thought as she made her way back to inform anyone from within reach.

The squad 2 captain Mukuro Sazumushi appeared. He had just killed a hollow that was trying to feast on a family.
"Captain" He called out. He scurried over to her. "What's causing all this?"

Spoiler:

Soukatsui!

*A huge blast of blue energy slams into a group of hollows, vaporizing them. Then out of the smoke Nachos walks out with a flat face*

-_- Ok, now what's going on?

"Nachos" Mukuro says. He waves at him as another hollow shows up. With a flick of his wrist, he cuts the hollows mask with his zanpakto.
"The hollow have begun, acting a bit..well, strange" He said to him.

A group of Hollows nearby approached Nachos and Mukuro, but they were frozen solid in an instant. By the time Toshiro touched down, the group of Hollows were shattered to pieces. "Karakura Town has been switched with a fake one....again." he concluded as he approached Captain Sazumushi and the Captain Commander. As usual, Hitsugaya had a serious look on his face, but he tried his best to keep the air around him at 40 degrees. I hope that it isn't too cold for the Captain Commander... Toshiro thought with slight concern of his impact on the environment.

*Nachos draws his sword and slices an incoming hollow in half, then looks at Toushiro*

Yo, Snowball! It's been awhile, don't worry, I love the cold. But why would Karakura be replaced?

Mukuro sighed. "Keep your spiritual pressure handled Toshiro" He said under his breath.

"Apparently, the Kido Corps thought that a crack in the sky of the Living World would prove to be a threat to the humans. So they did a switch, just like the one that was used to protect Karakura from the original Espada." Toshiro said as he stabbed a Hollow, causing it to freeze solid before it fell down and smashed to pieces. As they talked it over, the temperature was returning back to normal. "However, there has been a recently drastic decrease in the human population. What's stranger is that they all disappeared from the Opera House in Karakura, 1000 simultaneously." Toshiro added with a sense of great suspicion, thinking that there was something that they were overlooking.

"Toshiro, that has nothing to do with this at all" Mukuro said. "That happened long before any of this happened, and it was already solved by Suzaku"
He held his hand up when a hollow grasped onto it.
"Really?" He said. He gave a =_= look when he killed it with his zanpakto.

"Replaced karakura town, eh?" Sachiko then greeted the group of high ranking officers already gathered. "Interesting theory, however, it's highly unlikely... I lost all contact with our living world comrades, try it yourselves, you'd be surprised to see that even the hell butterflies are disturbingly disoriented."

Turning to see another horde of hollows fighting for space to get through from a garganta Sachiko sighed.

"If they successfully did the switch in time, non of this would've happened. Sad to say it, but they failed, it would seem that we lost the living world, and as an effect to that lost... this lower creatures could already feel what's coming towards us.."

Suzaku gave a look as more hollow showed up. He slashed at them, killing one after another.
"Are the hollow thinking for themselves due to this?" He asked.

"They are thinking about themselves yes, I think they are here out of fear, or that the Living world through them away, its like animals, they rune under the first sense of danger, i think its the same with this species."

Standing up she counted how many there were of them.

"Okay, lets split in four groups. One north, one south, one east and one west, that's where i sense the surges of energy coming from."

Spoiler:

"I will head on towards the Northern district, anyone who feels like following me should."

Suzaku nodded his head. "I'll take the south way" He said softly. He turned around, facing south now.

Trekking the roofs of Rukongai's northern district, Sachiko picked up the phase and gave the others who were following her a fare warning of what was ahead of them, but within an instant something huge came out from a crack in the sky. It looked to be a foot and from it came an arm which swapped Sachiko side wards, causing her to hit several buildings.

It caught her of guard, something which alerted the ones who were following her.

"What on earth... is that thing?" asked by one of the convoys.

Cautios, they didn't try to do anything, until confirmation from Sachiko her self.

Spoiler:

Suzaku darted towards the southern part of Rukongai. He jumped over buildings and ran atop the roofs. As he came to the end, he noticed a large hollow, that looked deformed and was emitting strong spiritual pressure. He pressed a button on his ear, trying to contact Sachiko.
"Commander, i have found the anomally here" He said. "There's something off about it though"

Pushing parts of the caved in roof above her Sachiko stood up hearing Suzaku from the other line. "It shoved me away, thank you, but im quite aware, what do you reckon it is? It's not to be looked down upon, it got me pretty good?" Speaking while she made her way back, she realized the group she left were now reduced to just her, they vanished.

"My group vanished, take care of yours."

She took a good look over the abomination before her eyes, it was nothing like any hollow she's ever seen, it emits enormous reiatsu, and it was just a leg, upon closer study.
