Demon Infernal

A is a horned Infernal, characterized by their more durable bodies, more powerful offense, and its ability to only be extinguished by extremely strong attacks.

Overview
Only a select few can become Demons under unusual circumstances; either artificially by the Bug, or naturally through Spontaneous Human Combustion. These types of Infernals are much stronger than normal Infernals, with skin that cannot be sliced by the Iai Hand-Sword Style, a technique by the strongest Fire Soldier Benimaru Shinmon, nor can be cut by a plasma blade. As a result, it requires a tremendous amount of power to destroy a Demon. Compared to normal Infernals, they have a much stronger heat signature. It is possible for Demon Infernals to also be sentient, as shown by Tempe.

Known Cases
Asakusa Demon - In Year 196 during the outbreak across Tokyo, a Demon Infernal appeared in Asakusa. Konro then fought against the Infernal, during which its horn scared Konro's face. Immediately after receiving the wound, Konro incarcerated the Infernal at the cost of charring his body in the process. The scars caused Konro to see visions of another world.

Haran - White-Clad member Haran willingly swallowed an infernal bug in a bid to destroy Asakusa, successfully transforming into a Demon. After successfully battling Shinra and Aruthr, he is finally destroyed by Benimaru's Iai Seventh Form - The Sun, followed by the Crimson Moon.

Tokyo Demon - Created by White hoods during the Fifth Pillar incident, Destroyed by four Special Fire Companies working together to trap it inside a firestorm and using Hinawa's Bullet Speed Rampage and Karim freezing the explosion into a giant pillar of ice.

Tempe - The oldest demon known found in the Chinese Peninsula near the Amaterastu-like engine found in the oasis. After 200 years of existing, he was finally destroyed when Shinra channeled the power of the Black Lady to use his Adolla Burst abilities.

Ms. Kusakabe - After witnessing Shō surrounded by the Adolla Burst flames upon awakening his abilities, his mother was transformed into a Demon Infernal. Upon seeing the Evangelist, she tore her horns lower down her face in the place of her eyes. Under the control of Haumea, she brought Shō the order and fled the scene. According to the First Pillar, she is still alive. Her current location: unknown.
