My idea for another story

Hello all... I am hoping to begin a new story-line (Which will feature the lieutenants as a group: Raine Shiba, Izuru Kira, Momo Hinamori, Rangiku Matsomuto, Shuhei Hisagi, and Abarai Renji) which will include the lieutenants listed and the captains (Including Ruka Kusabana, Toushiro Hitsugaya, Mayuri Kurotsuchi, and Byakuya Kuchiki). The summary: Raine is faced against an organization forming within the outskirts of Sereitei, in a hidden area known as the Hidden Valley. This Organization, is a giant group of trained soldiers, who wield zanpakutos that are twisted, after their head scientist stole Mayuri's research on modifying zanpakutos, they created a special form of zanpakuto that includes mechanical technology when released. When at first Raine witnesses an attack from them, by the secondary leader of the organization, he is rebuffed by most of Sereitei on his claims that there is a new enemy... Eventually, this organization begins to attack the Gotei 13, as a means of exterminating all other zanpakuto and their users... and still under the impression that they do not exist, Yamamoto does nothing to stop the madness. Raine rallies a group of lieutenants with him, the lieutenant's mentioned above, and leads an journey to the Hidden Valley. Furious, Yamamoto sends the four captains listed above after the lieutenants, to bring them back. Along the journey, Raine and the group meets a former member of the organization, who had left them due to their excessive thirst for bloodlust and power, who goes by the name Daiki Sasaki, who appears as an 11-12 year old child, but appears very strong in spiritual pressure for someone his age. He wields one of their mechanical weapons, a gunblade, and helps Raine find the location of the fortress within the Hidden Valley... From there, a series of battles begin... and a new adventure is born!

(Further ideas: The Organization are clad in black leather, all of them wearing long leather sleeveless trench-coats. Each of them have masks that cover their entire faces, leaving only one open hole for the eye, but the rest is a smooth black leather which is attached to the coat's collar, like a hood. They each carry a zanpakuto with a black hilt.)

(The leader, Konton (Chaos), wears the same uniform, except he wears a long flowing black cape behind him with a hood, he wears a golden mechanical mask that resembles that of a skull... )
