Rank-E is one of the six Jutsu classifications. It is followed by Rank-D. It is used exclusively when classifying Jutsu intended for Academy Students. A number of E-Ranked jutsu must be learned before ninja can graduate, and are only difficult in the sense that students may not have learned how to properly control their chakra. With time, E-Ranked jutsu such as Kawarimi no Jutsu become second nature for seasoned ninja.
