Shinjiro Ten-Ja Group

The Shinziro Tenga Group (信越·シーロテンガグループ; literally meaning Gaze of Hell Group), or simply Shinziro, are a collective group of criminals ranging from pretty criminals, to S-rank missing-in, and the main antagonists in Kimza Chronicles: The Last Sealer. With a highly evolved ranking system witha cryptic side, Shinziro is the fanfiction's future equivalent of the Akatsuki, only with far more members and a more sinister goal. Saphiro Kimza, the main character of The Last Sealer and its prequel, Kimza Chronicles, was once a member of this group.

History
It is unknown who started Shinziro, as it was founded more than 65 years before the events of Kimza Chronicles. It was at first merely a bounty-hunting group who had not ties to any village. However, it is known that a man by the name of Daigaru Meitochi, former leader of Shiragakure and eventual Akatsuki member, eventually seized power years later. Daigaru turned his attention to the many ninja that led their homelands for various reasons. Using his intellect and remarkable near-kage level skills, Daigaru forged a home for these ninja and they followed him, becoming treasure hunters and mercenaries. He named the group Shinziro after a genjutsu he had survived against years before.

A few years later, Daigaru ran across the remains of Arizogakure, a village destroyed Ezemaru Kimza. There, he found a scroll written by the Kuguari clan. Within the scroll was a legend of Tenga Hell, a monsterous otherworld in which beasts made of murderous intent and chakra roamed free and urged to kill everything. This made Daigaru wonder if there was some way to tame the beasts.

Shortly after finding a scroll and a few years before the Naruto storyline, Daigaru gave command of Shinziro to his closest friend, Otoshi Nagare, and joined the Akatsuki to find a way to unseal Tenga Hell and control the beasts within, knowing that the Kimza and Kuguari clans were extinct. He was teamed up with Kakuzu and eventually was appeared to have been killed by his partner in a fit of rage. However, the last bits of Bukarok's essence within the scroll revived Daigaru, as well as nearly driving him insane.

With his murder by Kakuzu used as a cover-up, Daigaru returned to Shinziro and resumed leadership. He and his group of mercenaries were soon grafted with more of Bukarok's power and they soon craved for learning the secret of Tenga Hell. He then used the money from mercenary jobs to create a base of operations. Howeverm due to the rivalry with Akatsuki, Shinziro was forced to watch the world and evolve during the events of Naruto.

After the Akatsuki is defeated, Shinziro began spinning its wheels again. It gathered many other S-ranked villains and grew in size. After an assassination attempt, Daiguru decided to have two of his most trusted and most powerful subordinates protect him, creating the Left and Right Guards. He then promoted the next strongest nine operatives as the commanders of the regular forces as well as the special mission operatives, making them the Nine. He then called himself Ziro, or "The Gaze". He lastly named the group the Shinziro Tenga Group, reminding himself of his goals.
