…Ichigo was deep in thought as Hirako finished his tale. He was exhausted and angered at the same time. Ichigo than looked at the blonde and with renewed energy and conviction, he agreed to join these banditos with their plan to achieve revenge on the mafia…
Ichigo was crestfallen as Hirako told him that Rukia had been captured by the mafia's hit man. He had promised himself to not let her fall in the mafia's hands. However he had failed. Now he looked at the Head of the Banditos as he pulled up a chair in front of the couch and signalled for Ichigo to sit opposite him. The orange head sat down sullenly as he listened to Hirako Shinji's story.
"Some twenty years ago, the mafia was becoming stronger and the law enforcement was becoming increasingly corrupt. I was still a young officer at that time, as most of my fellow banditos here. We became involved with a powerful man who was trying to join the police and the mafia under one force. Obviously this force was to be controlled by himself. This man was Aizen Sousuke. My comrades and I uncovered his devious plot. He managed to send men after us and he made us 'disappear' before we told any other officer about our findings. Our disappearance was actually abduction to one of his secret research facilities. The Researcher there was a cold and wicked scientist called Mayuri. He conducted experiments on us. These experiments were crude and inhumane. Their aim was to stimulate unused areas of the brain into activity to create a perfect weapon for the mafia. They stimulated our brains in order for us to become faster and more efficient killers. And if things had to go according to their plan, we should have developed supernatural or psychic powers. After five years of imprisonment and testing, the law enforcement consisted only of a small branch. This was lead by the current Chief Sheriff Yamamoto Genryuusai and Kuchiki Byakuya's grandfather.
Aizen Sousuke had managed to take control of everything. He was the absolute lord of Mexico. One member of the remaining sheriff force was Urahara Kisuke, who had been investigating our case on his own. He managed to track down our location but the Sheriffs denied everything and relieved him of his status within the force. Thus, with the help of Yoruichi, who is now his wife and Tessai, he worked out a plan and managed to infiltrate into the facility and liberate us. His plan worked, and we the test subjects rebelled and assassinated the researchers. We then burned all the documents and escaped. There were other test subjects who were too hooked up on the Inhibitor and were just husks of their former selves. These didn't survive, despite Urahara's efforts. He managed to save our lives and taught us the way how we could control our powers without losing our humanity to them. After the up rise, we kept an eye on the mafia, and thought that the Project Hollow was abandoned. However we were wrong. Around five years later a new researcher appeared. Szayel Aporro Granz who built a new facility in Hueco Mundo and improved on the research. He selected the candidates carefully and performed more accurate tests. The candidates were all children, especially orphans since they learned to be more resilient in order to survive on the streets. Kuchiki Rukia was one of them. It seems that she was the most successful candidate and thus the most powerful; although we only came to know all of this a few years ago.
Rukia, destroyed the facility, killing everyone there except for the other children. She then escaped on her own and disappeared. I guess she hid while living with the orphans with Padre Sado, until she was discovered again by Kuchiki Byakuya and in turn by the mafia some months ago as she responded to her vice-sheriff's mortal wound and tried to heal him unknowingly. That marked her as Aizen's target who still has some influence on a couple of officers. Thus, he led to her execution as he planed to intervene while the Sheriffs were transporting her to the city of Seireitei for her execution and take her to Las Noches instead.
However, their plan changed when someone helped Rukia escape from prison before her transportation, and thus the manhunt began.
Ichigo- the mafia plan on attacking The Organisation and crushing it to its roots. This time no one will be spared and he will use these powerful assassins to achieve this. I and my fellows intend on stopping this and that is why we need your help too. Urahara has also managed to confirm that a number of Sheriffs will help this attack and we will bring the mafia down. It will be the beginning of war. The eternal battle of good against evil. So will you join Ichigo?"
As Hirako Shinji stopped talking, he looked gravely at Ichigo and maintained his steady gaze. Ichigo looked down slightly as he clenched his fists and then looked up with a grim smile as he replied; "Count me in".
