Azure Flame (紺碧の炎, Konpeki no Honoo)
Flame Ogami's element is fire. At first, it is shown that he can cover anything he touches with his left hand in blue flames that can burn fire itself. It is later shown that if he removes the ring on his left hand, his power and reach increase dramatically, to the point where it is hinted that he can use pyrokinesis. This special power originated from the arm of Code:Emperor that was given to Ogami (hence why he could only generate it from his left hand). Later on, he was shown to be able to channel it through his entire body, since he possessed this power long before he received Code:Emperor's arm. Ogami offered his sense of taste as payment for this flame. The sin it represents is Wrath.
Belphegor (ベルフェゴール, Berufegōru)
P16 17 Belphegor Belphegor is the Black Flame of Limbo that Ogami received from Code:Emperor in chapter 103 when he briefly died and went to hell. This flame burns the Special Power instead of the person, nullifying its effect. Ogami can also use this flame to burn and nullify the effect of abilities used on his body, as Chibigami did after Code:Revenger turned back his time, nullifying both Yukihina's ice and Code:Revenger's ability. Ogami used the "Sound" he received from Yuuki as payment for this flame. The sin it represents is Sloth.
Mammon (マモン , Mamon)
Mammon Mammon's first form was that of a twin-headed beast, which was able to destroy all of Heike's clones by causing a massive explosion. In his battle with Toki, Ogami showed to have full control over Mammon and could summon its true form: the Dichromatic Twin Flamberges of the Netherworld. In its true form, the hot blue flame and cold yellow flame can interact, making the temperature differences change the air pressure, which creates a gigantic whirlwind of scorching heat. The sin it represents is Greed.
Beelzebub (ベルゼブブ, Beruzebubu)
Codebreakerbeelzebub Beelzebub is the Achromatic Catharsis Flame of Purgatory and the wielder of the Flame of Judgement. Beelzebub is capable of unleashing a colorless flame, at a temperature exceeding 1500°C, to instantly incinerate anything. Ogami first tried to use it in his battle with Toki, but was unable to control it. Once Heike returned the missing part required to control it, Ogami was able to summon its incomplete form and defeat Toki. In chapter 162, Ogami finally mastered Beelzebub by consuming the demon and fusing with him. In its true form, Beelzebub can call a rain of fire to descend from the sky, instantly disintegrating anything around Ogami. However, the damage it inflicts rebounds back to Ogami with the same intensity. The sin it represents is Gluttony.
Leviathan (リヴァイアサン, Rivaiasan)
Leviathan Leviathan is the Argentous Phantom Flame of Hades and the strongest of the demons shown yet. Leviathan is first summoned to fight "Reggae Four-Eyes" after Ogami felt intense rage towards him. Initially, Leviathan appeared to be very reasonable and polite, unleashing a silver-colored flame that shredded the Rare Kind to pieces (supposedly its true power). After sensing Reggae Four-Eyes's envy, however, it showed its true demonic personality and power: the capability of freezing its targets by removing the heat from the area. Sakurako Sakurakouji gave Ogami the ability to use it when she kissed him. The sin it represents is Envy.
C019 Asmodeus is the Iridescent Explosive Flame of Hell, which Ogami obtained after taking posession of the demon from Kagerou. At first, Asmodeus displayed the ability to trap people inside an illusion of lust, while slowly consuming them. Its true power, however, lies in its capability of producing massive explosions of iridescent colour (due to chemically reacting with the surrounding alloys). Furthermore, the sound produced by the explosion can shatter the inner ear of people with sensitive hearing, like Yuuki. In order to gain control over Asmodeus, Ogami offered his sense of smell as payment. The sin it represents is Lust.
