The plot so far:
The Winter War is over. Aizen won. Even after the Vizards showed up, he was still simply too powerful for them. When the strange little Arrancar Wonderweiss released his true power, the Shinigami and the Vizards realized just how much they had underestimated Aizen. They gave the battle their best shot, and managed to defeat some of Aizen's forces, but they still lost. Ichigo Kurosaki gave Aizen a run for his money, but Aizen was able to easily dispatch the substitute Shinigami. When the battle ended, Aizen opened the gate to the King's domain, and it is there that we begin…
The tall Shinigami stepped forwards towards the shining gate. He drew his white robes up as he stepped over the body of a young boy with white hair, a repulsed expression on his face. As he approached the gate, he turned and looked around the battlefield.
To his left, the bodies of a young girl with spiky blonde hair and a teenage girl with a black ponytail.
To his right, the bodies of a large wolf-like creature with a sword and a black man with dreadlocks and a visor.
In front of him, the body of a black-haired man in a fur coat and a man with a strange star-shaped afro.
And all around him, more people struggling to stand up, barely grasping at life.
Interesting… The strange boy's body is gone. But it is no matter. I have reached the throne of God, and no one shall take it from me.
Aizen turned back towards the gate, a smile on his handsome face that was marred by a large bloody scar stretching from his left eyebrow to his right cheek. He started to stride towards the gate, then stopped as it began to open.
Standing in the gate was a figure totally hidden in shadow.
"Ahhh… Hello there, Sosuke-kun…"
The figure disappeared.
Aizen looked down, his expression changing from one of malicious happiness to one of confusion and fear. He stared at the blade protruding from his stomach, its edge dripping with Aizen's own blood.
