The Shinjiro Tenga Group (信越·シーロテンガグループ; literally meaning Gaze of Hell Group), or simply Shinjiro, 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 and Kimza Chronicles: War Against Hell. With a highly evolved ranking system witha cryptic side, Shinjiro 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.
