A Storm Flame is one of the type of flames in the Dying Will Flames of the Sky.
The core of a Storm Flame is an ordinary red shade. Its inner layer is pale red, almost pink-like. The outer edges of the Flame are deep crimson. In the manga, the outer edges of the Flames are distinctively dark. The core and inner layer seem to remain intact while outer edges of the Storm Flame "burn" erratically and form soft tendrils before leaving from the main body.
Storm Flames are highly offensive, primarily used for attacking. With its Disintegration characteristic, it causes anything that it touches to decay and break apart, including other Dying Will Flames. It can also minimize the effect of other Flame-enhanced attacks or break through other Flames.
