However, you are not completely safe as gripping someone from the same organisation as you will make them Rogue (a requirement to join some clans). Think of it that you are solo allied with any clan that resides within the same organisation you are within, almost like how an Uzamaki wouldn't attack anyone from the leaf village in Naruto.
Organisations are basically your starting 'clan', although you are not officially apart of them you are still inside of them. ' Think lightly of yourself, and deeply of the world.' -Miyamotom Musashi Description
