S-rank

An S-Class nin is a ninja who has gained far beyond an average Jonin and have earned a legendary, and feared status. The title itself isn't a offical rank and the village offically refers to them as Jonin, but thats not always the case as some would argue Naruto Uzumaki is an S-Class ninja though he is still a Genin. Some ninja who have achieved this rank sometimes leave their villages to seek their own ambitions, such as most of the members of the Akatsuki, thus becoming missing-nin and having no rank at all. All the major ninja villages put their S-class missing nin in the Bingo Book, marking them for assassination for all Jonin and ANBU ninja. Most ninja however adopt a "flee on sight" policy rather than fight one. Most Kage's tend to be S-class, and sometimes a team of S-class nin would be given nicknames by their allies and enemies, such as the Sannin.
