Prologue—

A man in shinigami clothes walked up to the outside west gate of Seireitei. He walked slowly but confidently, his bushy black hair blew with the gentle breeze as a giant man landed in front of him.
"Halt!" the giant yelled with authority "I am Jidanbō! This is the western entrance to Seireitei and I am its guard."
The shinigami looked up as Jidanbo reflected in his cold silver eyes, as if he was staring through him.
"Proper clearance is required to grant your passage." Jidanbo stated as he held his ground.
The shinigami walked up to Jidanbo his head only measured up to his knee cap. "I am Tsuyoshi Takeru. That's all you need to know." He said as he placed his hand on Jidanbo's kneecap.
"Tsuyoshi Takeru?" Jidanbo said in disbelief as his eyes widen. "The Soul-" his pupils shrunk instantly as he fell over, his right kneecap and below completely lost in a sudden explosion of light out of Takeru's palm.

Takeru lowered his hand onto his unreleased zanpakutō's hilt and within an instant, a vertical slash appeared on the gate. The gate quickly started to crumble before him as he hopped onto the rubble. "Today is the day I kill you, Captain-Commander Shigekuni Yamamoto-Genryūsai." Takeru stated with a cold emotionless face.
