E-rank

E-Rank is the lowest ranking for techniques. These include techniques that are learned in the Ninja Academy along with a few other techniques. These are very basic techniques learned by Academy Students. All Academy graduates are able to use techniques in this category. Examples are:

Academy Techniques:

 * Body Replacement Technique
 * Clone Technique
 * Transformation Technique
 * Rope Escape Technique/Escaping Skill

Other:

 * Sexy Technique (Used by Naruto and Konohamaru Corps only) (Transformation Technique)
 * One Thousand Years of Death (Known to be only used by Kakashi and Naruto)

E-Rank is not considered a mission rank. D-Rank is the easiest mission to complete. And also Academy Students are not able to go on missions, which is another reason why E-Rank cannot be a mission ranking.
