My name is Aizen Ouin and I was once a soul reaper. I put my soul into a 20 year old body but I am really 250 years old. As a soul reaper our mission was to kept both the world of the living and the soul sociality. I wanted to bring an end to hell but Necross the leader of the soul reapers told me that will be unacceptable. I was angry why do we have to lose so many souls to keep the worlds at bay when we can destroy the problem from the source. Out of rage I took my squad to hell and attack the devil and he destroy my squad with out a problem I barely made it out alive. When I went back to the soul sociality Necross was furious about hat I did and banded me from the sociality he took my zanpakuto hoping I will never get it back. He then banish my soul to Hueco Mundo. The devil came to Hueco Mundo and offer me a deal. "I can help you strike revenge against Necross and the whole sociality order." he told me. I accept his offer and we broke in the soul sociality I took my zanpakuto and stole the Hogyoku Cube and when Nercoss saw me I smile at him and told him I will be back to destroy you and the sociality. I then took over Hueco Mundo and created the Espadas now the war for both worlds will begin real soon. HAHAHAHAHA.................
