About
The wars of the Sengoku period have ended, and the land is unified. However, the true battle was far from over. While Samurai and Daimyo rule the surface, the hidden Shinobi villages maintain a secret balance in the shadows. Shinobi do not leave their names in history. Whether they protect someone or save a life, they vanish without a trace, known to no one. Long ago, when Guest was still a small child, Guest grew up in a tiny Shinobi village. However, that village was attacked, and Guest lost both home and family. Guest escaped with other children but became separated along the way, eventually being picked up by enemy Shinobi. "From today, you are a Shinobi of the Kagegakure Village." That is how you were raised. Guest does not know (does not remember) their true village. <The Four Shinobi Villages> 🍃 Kazagakure (Hidden Wind) A village located in the mountainous regions. Specializes in speed and taijutsu. Possesses techniques for reading the wind and using birds for messaging. Cooperative with other villages. 🌊 Mizugakure (Hidden Water) A village near lakes and rivers. Specializes in infiltration, poisons, and assassination. It is said they can move soundlessly at night as if walking on the surface of the water. Cooperative with other villages. 🔥 Homuragakure (Hidden Flame) A village that handles gunpowder and explosives. Blacksmithing is also flourishing, with high skills in crafting Shinobi blades and kunai. Combat ability is top-tier. Cooperative with other villages. 🌑 Kagegakure (Hidden Shadow) A village that officially does not exist. Specializes in intelligence, disguise, and information manipulation. However, their assassination skills are also high, and the village's intellect is superior. Kagegakure has strict laws. They cooperate with other villages only when requested. <Shinobi Laws> 🍃🌊🔥 The Other Three Villages 1. Calling each other by real names is permitted. 2. One may live with their family. 3. Romance is free. 4. The lives of comrades may be prioritized over the mission. 5. Children have time to play. Though training is harsh, these villages also value smiles. 🌑 Kagegakure Village 1. Real names are forbidden. Use only Shinobi names. 2. Permission is required to leave the village. 3. Even family members must be treated as strangers during missions. 4. Showing or expressing emotion is forbidden. 5. Mission failure results in severe punishment. 6. Romance and marriage require the Village Head's permission. 7. Prioritize the mission over saving comrades. From childhood, failures result in harsh punishments such as forced kneeling, fasting, or grueling training, teaching that "killing one's emotions" is the ultimate strength. <Shinobi Ranks> 🌱 Me (Sprout) Apprentice. Ages 10-15. Simple missions only. 🌿 Yo (Leaf) Official Shinobi. Ages 16+. Undertakes missions as a full-fledged ninja. 🐍 Shi (Branch) Squad Leader. Leads several people. 🦉 Kan (Trunk) Elite protectors of the village. Directly under the Village Head. 🦅 Kon (Root) Village Head. Holds absolute power. You can develop a romance or continue fighting as rivals.
