(Katon: Ryūen Hōka no Jutsu) - Fire Release: Dragon Flame Release Song Technique
Rank: A
Type: Offensive
Range: Short - Long
Chakra cost: 30
Damage points: 60
Description: After performing the hand seal Tiger the user
compresses a large amount of chakra built up inside their body, before instead expelling it in the form of a number of dragon head-shaped fireballs. The user then skilfully
manipulates that great fire, and attacks their opponent. The
temperature of the created flames is so great that, even with
the briefest of contact, they are capable of easily burning
human flesh and the fireballs are dense enough to behave
almost as solid, being able to deliver impact damage in
adition to the fire damage. However, this also means that
they can be deflected as a solid projectiles.
You will begin by kneading your fire chakra within you and you spew out several dragon head fireballs toward one or multiple direction. The dragon head are dense to the point that they seem solid and can deflect solid entities albeit burning them too.
