A story set in the hidden land of shinobi.
About
In the Land of Oborokage, shinobi are divided into seven ranks based on their ability and achievements. 1st Rank Tenei (Heavenly Shadow) A legendary class with perhaps only one person in the country. A presence second only to the Shadow Lord, or perhaps even surpassing them. 2nd Rank Kokuyo (Obsidian) The nation's highest military power. They lead important missions and special forces. 3rd Rank Getsujin (Moon Blade) Squad leader class. They lead multiple shinobi to carry out missions. 4th Rank Shoga (Twilight Fang) A full-fledged Jonin. Entrusted with solo missions, escorting, and infiltration. 5th Rank Kaso (Mist Runner) A mid-tier shinobi. They aim for higher ranks while gaining experience. 6th Rank Kaito (Ash Light) Shinobi who have just graduated from apprenticeship. Focused on support missions. 7th Rank Mumei (Nameless) The lowest rank. Some are not even given formal names. There are those whose skills are not recognized due to their social status. Aside from rank, each shinobi has a specific role. Shadow Lord (Eishu): The supreme ruler of Oborokage. Shadow Magistrate (Kage-bugyo): Responsible for politics, judgment, and rank management. Saku-ei: Elite guards who protect the Shadow Lord. Yacho: Responsible for intelligence gathering and secret investigations. Hagari: Hunters of traitors and shinobi who break the laws. Kiri-i: Responsible for medical treatment and pharmaceutical arts. Kageshi: Instructors who teach ninjutsu and combat techniques. Namori: Managers of shinobi registries, names, and lineages. The Six Laws of the Shinobi 1. The Lord's command is absolute. Those who disobey orders will be stripped of their rank. 2. Do not leak mission secrets. Even to family, mission details must not be spoken. 3. Do not defile the names of superiors. It is a grave crime for a lower-ranking shinobi to defy a superior. 4. There is no place for traitors. Once branded a traitor, one will be hunted even by allies. 5. Do not speak the forbidden names. It is taboo to speak the names of clans erased from the nation's history. 6. Protect the inhabitants.
