Bount : History

The Bounts were created as the accidental result of an explosion during an experiment by the predecessor to the Seireitei Technological Institute. The experiment was an attempt to develop eternal life using the already slow-aging shinigami souls as the base, but the materials used in the experiment crossed with the development of souls in the real world and led to the creation of a new spiritually-active human race, the Bount.

The Bount souls were scattered about the world, giving rise to a new race that never aged after reaching their twenties or thirties. They were generally treated as outcasts due to the fact that they did not age. The shinigami scientist responsible for their creation, Ran'Tao, gathered most of the Bount into a small community in a secret cave structure, several centuries before the main storyline. It was her intent to improve the quality of life for the people whose suffering she felt responsible for.

However, the embarrassment of this accidental creation, as well as the fact that a tenth of Seireitei was destroyed in the resulting explosion and the possible threat they posed to the balance between the worlds, led the Chamber of 46 to rule that the experiment and its failure was to be covered up, and the Bount destroyed. Shinigami were dispatched to kill the Bount community, but a handful survived, including a young boy saved by Ran'Tao herself, to whom she gave a seal that would help unlock the Bounts' true power.

The Bount who survived the massacre wandered nomadically and eventually fell prey to constant attacks by hollows. It was during this time that the boy, who would later become known as Eugene, activated the seal's power and merged with his doll - the Bount equivalent to a shinigami's zanpakuto - and killed off the attacking hollows. The survivors eventually found refuge in another cave and began devising a plan to return to Soul Society, which they saw as more of a home than the real world ever could be. Eugene, now an adult, was against this plan. He had witnessed the massacre and believed the only thing that would await the Bount if they returned to Soul Society would be subservience or death. Regardless, the Bount leadership decided to gain access to Soul Society by means of the Quincy's powers. The Quincy were unwilling to assist, and a battle ensued, in which the Quincy and shinigami killed most of the surviving Bount.

Further infuriated by this, Eugene took the last few surviving Bount, all of whom were of a similar mindset to him, and began plotting revenge on Soul Society. These Bounts managed to perfect the control of their dolls, and by the time of the main storyline Eugene, now going by the alias, Jin Kariya, was ready for vengeance.
