Akuhei's Newest Jutsu

Name: Dragons of Retribution
Rank: E-SS
Type: Ninjutsu
Element: Katon
Range: 0-15 meters
Clan: N/A
Description: The user must first spend an entire post focusing their chakra before they can even begin to use the long string of handseals. At the end of these handseals, the user makes the bird handseal and puts their hands to their face so that the opening created by their hands is directly in front of their mouth. The user then blows out the chakra, creating a number of (Eastern-style) dragons. These dragons then wrap up and burn the opponent unless countered with a water-style jutsu one rank below or a fire jutsu of equal rank. The number and strength of the dragons are dependent on rank:
E-rank: 1 dragon, destroyed in one hit, 1st degree burns.
D-rank: 1 dragon, destroyed in two hits, or with one D-rank attack, 1st degree burns.
C-rank: 2 dragons, destroyed in one hit each, 2nd degree burns.
B-rank: 2 dragons, destroyed in two hits each, or with one B-rank attack each, 2nd degree burns.
A-rank: 3 dragons, destroyed in one hit each, 3rd degree burns.
S-rank: 3 dragons, destroyed in two hits each, or with one S-rank attack each, 3rd degree burns.
SS-rank: 5 dragons, destroyed in five hits each, or two S-rank attacks each, instant roasting.
The jutsu requires a large amount of chakra, so if the user is Genin and using the D-rank version, they can only safely use it twice. If the user is Genin and using the E-rank version, they can only safely use it four times, etc.

your genin ...........

Yes, so I'd only be able to use D-rank.
