Special Fire Force Company 8

The is a Special Fire Force located in Tokyo. It was formed in a rush compared to the other Special Fire Forces, and, as a result, it only has a few members and doesn't have a science or research division. It is tasked with extinguishing and purifying the souls of Infernals and unraveling the secrets of Spontaneous Human Combustion.

According to Akitaru Ōbi, the role of Company 8 within the Special Fire Force is to overview and investigate the 1st through 7th Special Brigades, as they could potentially be hiding information from the entire organisation for personal reasons.

History
Some time after joining the brigade, Shinra and Arthur both participate in the Rookie Fire Soldier Games, with the rest of the brigade arriving at the scene as spectators. When the building the competition is being held in bursts into flames, the other brigade members successfully catch Arthur before he falls to the ground, while Shinra rescues two unconscious brigade members.

Following the Rookie Fire Soldier Games, Company 5 confronts the brigade for the possession of the Infernal Setsuo Miyamoto, which leads to a stand-off between the two. After Iris independently went to the Special Fire Force Combine 5 to talk with Princess Hibana, the 5th decide to hold her hostage to attract the 8th. All members of the 8th excluding Akitaru invade Company 5's Combine to retrieve Iris and locate any documents they could be hiding about Spontaneous Human Combustion. Takehisa and Maki manage to fight off the grunts, Tōru Kishiri and 3 Angels of the 5th, while Arthur manages to kill Setsuo Miyamoto. After struggling against Hibana's abilities, Shinra knocks her out with a punch. After the feud, Hibana chooses to cooperate with the 8th.

Missions

Dispose of the paroled Infernal in the courthouse The brigade is tasked to dispose of Setsuo Miyamoto, an ex-convict who had turned into an Infernal and was causing havoc in the courthouse. Arthur and Shinra combat the threat first, with the rest of the brigade arriving to support the two later on. When the Infernal attempts to surrender, in the hopes that his life will be spared, Takehisa shoots him, forcing the man to use his flames which causes a diversion that allows him to escape. Promising to kill innocent people, the threat is left for Shinra to fight, as his Ignition Ability alone allows him to catch up to the fleeing opponent. Shinra continues to fight the opponent on his own, only to be stopped by Hibana. Akitaru later arrives at the scene and agrees to leave the Infernal in the hands of Company 5.

As the Company regroups and prepares to leave, they are berated by a woman close to Masao who accuses them of murdering him despite saving her life in the process. It is decided that it is best to let her blame them as an outlet for her grief.

After the surprise addition of Viktor Licht to Company 8's science department, Captain Akitaru sends Iris, Shinra and Arthur to see if they can recruit a legendary engineer known as Vulcan Joseph. Despite his intense dislike for the Fire Force and Haijima Industries, Vulcan begins to find common ground with the young officers when they visit his workshop. The group is attacked by officers from Company 3, who are also members of  the  Knights of the Ashen Flame. While they are initially successful in repelling their attackers, Shinra is subdued, Arthur struggles against his opponent and Vulcan is incapacitated by the betrayal of Lisa, one of his closest friends.

Contain the mass Infernal Outbreak With at least 8 Infernals rampaging through the city and a large fire appearing as a result, Company 8 focuses on aiding the evacuation and containing the situation. While Akitaru is able to defeat 3 Infernals, Maki realises that the Infernal's numbers are growing rapidly. This is assumed to be the result of the bugs and White Hood involvement. Company 8 quickly finds themselves overwhelmed, with even Vulcan being forced to fight and Tamaki aiding with the repose of the Infernal souls. The situation is made worse when a Demon-Class Infernal appears. Through the aid of Company 1, Company 2 and Company 5 they are able to regain control of the crisis. Licht is able to organise a plan using the various types of Second Generation fire control among the 4 companies to create a massive firestorm out of the fire raging in the city. After Vulcan and Akitaru force the Demon into the pillar of flame, Takehisa fires a mortar shell through the storm and uses the surrounding flame to massively accelerate his shot so it has the power to obliterate the demon. Lieutenant Karim Flam then freezes the firestorm solid.

While the rest of the company focuses on containing the Infernals and blaze, Shinra is sent to locate Inca and protect her from danger. Shinra spots the girl from above and interferes in Charon's abduction attempt. However due to Inca's stubbornness and  Charon's power, Shinra is quickly overwhelmed and is almost abducted, as the Preacher plans on using him as the 'Fourth Pillar'. Fortunately he is freed from captivity by  Tōru Kishiri and Takeru Noto and continues the fight. Despite Shinra discovering the nature of Charon's ability and unleashing a powerful attack, his foe quickly recovers and Inca chooses to join the White Hoods of her own will.
