His fire seems to be generated and shot out in black and red flames and is very powerful yet dangerous. Like regular fire magic, Rakutsu can change the properties of this Magic such as its "form", allowing it to take shape as a gas or solid element. This magic can also work in a similar fashion to explosives. He is able to conjure this element from various parts of their body or from the nearby surroundings.
Rakutsu can create fire based attacks and has a high resistance to most heat based attacks. The flames can also be used to bolster the kinetic force of his physical attacks and even propel himself. Unlike normal fire magic, the dark fire magic seems to be strengthen by negative emotions making the attacks more powerful when it is fueled by them.
Naturally this magic has a nature weakness to water.
