D-rank

D-Rank is one of the six classifications. It is preceded by E-Rank and followed by C-Rank. It is typically used when classifying jutsu intended for ninja of the Genin level. D-Rank jutsu are often one of the first jutsu a ninja will learn after leaving the Ninja Academy.

There are also D-Rank missions, the lowest classification a mission can receive. These missions are usually assigned to Genin. Naruto Uzumaki describes D-Rank missions as not being actual missions as they deal with tasks as simple as finding missing pets and weeding a garden.
