Special Fire Force

The, also nicknamed , are a fire fighting force, which was originally formed by members of The Fire Defense Agency, Tokyo Army and The Holy Sol Temple. All eight brigades investigate the Human Body Ignition Phenomenon and purify the souls of Flame Humans.

Uniform
Members of the Special Fire Brigades wear bunker gear, which is shared by all individual brigades. Fire Officers from Tokyo tend to wear black helmets on their heads, with the letters "FIRE SOLDIER # TOKYO", which was later changed to "FIRE FORCE # TOKYO" (with # being the brigade's corresponding digit). They also wear large jackets, with bright neon-blue stripes across the arms and stomach-area, and a collar directing outwards. Their jackets have buttons in shape of a cross. On several occasions, members of their respective brigades were seen wearing orange jumpsuits, when off-duty, with the same cross-shaped symbol on their backs.

The uniform also consists of gloves and a neck protector. The Fire Officers wear stripped trousers, black-coloured shirts, buckled at the waist with a belt, and black boots. On the left upper-arm of their jackets, a number patch with the insignia of the brigade is present. The uniforms, however, are allowed to be customised, as shown with Shinra having his trousers cut shorter to reach above his feet, in order to compliment his ability to produce flames.

Overview
The main objectives of the Special Fire Brigades are to solve the secrets behind the Human Body Ignition Phenomenon and to purify the souls of Flame Humans. There are training facilities that a lot of officers, such as Shinra and Arthur, attend before joining the ranks of a Special Fire Brigade. Though all of the Brigades have the objective of discovering the secret behind the phenomenon, they differentiate in their own power and backgrounds. For instance, members of the 1st Special Fire Brigade originate from The Holy Sol Temple, while the 2nd and 5th Brigades revolve around the Tokyo Army, though the 5th is more influenced by the Haijima Heavy Industries, which plays a significant role in producing and equipping the Brigade forces with all the tools they require. New recruits participate in the Fire Officer Newcomer Tournament.

Because of the divide among the Special Fire Brigade's individual brigades, Akitaru Ōbi suspects that each of the brigades of the 1st to 7th are gathering information on the phenomenon, but are keeping it a secret and don't reveal their findings.
