The name Shinobu Kitsune does not appear in any archive or database. It's a false name, an alias, a mere identification code. Shinobu Kitsune is not a real person, they do not exist. They are a ninja. But not simply a stealthy assassin, martial arts expert, but rather an Oniwaban. A spy master that carries out the most dangerous field missions, or the ones that require the most responsibility.
