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 Force, and, as a result, it only has a few members and doesn't have a science nor research division. It is tasked to extinguish and purify the souls of Infernals and unravel the secrets of the Spontaneous Human Combustion.

According to Akitaru Ōbi, the role of Company 8 within the Special Fire Force is to overlook 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 was 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 5th Special Fire Fighting Industrial Complex to talk with Princess Hibana, the 5th decide to hold her hostage to attract the 8th, all members of the 8th excluding Akitaru invade the 5th's Industrial Complex to retrieve Iris and locate any documents they could be hiding about the Spontaneous Human Combustion. Takehisa and Maki managed to fight off the runts, Tōru Kishiri and 3 Angels of the 5th, while Arthur managed to kill Setsuo Miyamoto. After struggling against Hibana's abilities, Shinra knocked her out with a punch. After the feud, Hibana chose to cooperate with the 8th.

Missions
The brigade was assigned to stop an Infernal, who was going berserk in a train station. With the help of Maki, who provided defensive support in extinguishing the incoming flames, and Takehisa, who slowed down the being's movement with the Special Fire Extinguishing Bullet, Akitaru managed to impale the Infernal's core with his Core Annihilating Pile Bunker, killing him and allowing Iris to send off his soul in peace.

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.
