After creating a jutsu in "Jutsu Creation" it will be approved. But, it will not be officially approved until you train the jutsu in an OFF-RPG or IC topic that meets the following requirements for each ranked jutsu. For each jutsu you have there is a word count. The higher ranked the jutsu, the higher the word count.

D Rank Jutsu= 200 words

C Rank Jutsu= 300 words

B Rank Jutsu= 400 words

A Rank Jutsu= 500 words

S Rank Jutsu= 1000 words

If your a genin, you can not have B, A, or S Rank Jutsu, Chuunin can not have A, or S Rank Jutsu so do not think you can make a jutsu higher than your rank and train it and think it will be approved.
