Pendulum - The Butterfly Effect (Bleach FF)

1: Invasion

*The pendulum ticks back to 47 years into the past, where this all began.*

It was a cool spring night in the Seireitei where Yamamoto Genryuusei sat in this office, a mountainous pile of paperwork perched on the desk in front of him, tottering treacherously from side to side as though the faintest breeze would send it toppling across the room.

Yamamoto did not like nor dislike reading through the reports of his thirteen squad captains, but when his dearest Lieutenant Sasakibe wandered into his office carrying another pile of agonizing boredom, such as this monstrosity, his heart sank.

These papers are an extremely high priority, the sooner I read them the better, the old man urged himself. He leaned forward in his chair ever so slightly and slowly reached a wrinkled hand towards the top few papers. "No... sudden... movements..." he mumbled as if the vibration of his words in the air may send the pile flying.

As if karma was out to spite him, the towering wooden doors to his office came crashing open and a young man with short and messy mousey blonde hair wearing a Captain's Haori came skidding into a kneeling position in front of Yamamoto's desk, completely oblivious to the rain of paper falling from the ceiling.

Yamamoto held his face in his palm, despairing.

Why did I hire this buffoon? His stupidity never ceases to amaze me. It will take forever and a day to reassemble these papers in the correct order he thought, again regretting hiring the man all those years ago due to his consistent clumsiness.

"Captain Commander-" the man began to pant, out of breath and red in the face from running. Yamamoto cut him off before he could continue.

"Were you born in a barn, Captain Urahara?" he asked sarcastically.

"N-no, Sir... I was-"

"Then learn to knock before entering and close the door behind you" He snapped. "And collect these documents off my floor this instant"

"My apologies Captain, but I've come to report that the Department for Research and Development have detected a massive amount of Spiritual Pressure approaching the World of the Living, It's like that of a hollow's but multiplied one-hundredfold!"

This caught Yamamoto's attention and he stood up, momentarily ignoring the sea of paper. "You are sure of this, Urahara?"

"One-hundred per cent Sir, the spiritual pressure readings are off the charts!"

"And the location?"

"Karakura Town, in the West of Tokyo, Japan."

Yamamoto lifted one fluffy eyebrow in surprise. A small black butterfly with pink markings appeared from thin air and floated down to rest on Yamamoto's index finger and he leaned into spoke to it.

Every Soul Reaper in the Seireitei did as instructed and stopped their current action to listen to the wizened voice emitting from the air around them, as though through a giant invisible megaphone.

"Attention all officers: An immense spiritual pressure is approaching the World of the Living. Squads Two, Five and Nine are to be dispatched to Karakura Town to assess and handle the situation. All other squads, with no exceptions, are to remain on standby and patrol the Seireitei. Any suspicious activity must be reported and dealt with immediately. I will not allow these attacks and disappearances to continue."

Once finished, the Hell Butterfly fluttered off his finger and out of the nearest window. Usually, the Head Captain would call for a conference between the thirteen Captains to discuss details and action plans, but time was of the essence here.
