Sōichirō Hague

is the former captain of Special Fire Force Company 4.

Appearance
Sōichirō was an elderly man with short light colored hair and three scars across his face. He wore glasses over his squinted eyes and while on duty wore robe-like bunker gear. Despite his homely appearance, he had a toned muscular frame from years of service as a Fire Soldier.

Personality
While on official business Sōichirō was a calm, formal and polite man despite appearing to be very sinister. As a firefighter, Sōichirō was dedicated and driven to protect the lives of others. This drive caused him to become highly respected by the members of Company 4, but it also meant he was crushed by the guilt that there were people he was not able to save.

His personality took a sharp turn two years ago, where an encounter with the Adolla freed him from his personal guilt and changed his beliefs. As he felt he had uncovered the truth behind life and death, he lost interest in the Holy Sol Temple and grew obsessed over finding the secrets of Adolla, but chose to hide his opinions. Although when pressed about it, he does not deny the appeal of starting a religion of his own based on his beliefs. The encounter also left him desperate to experience an Adolla Link to the point of being willing to let someone with an Adolla Burst strike him, even going so far as to beg for it and respond with ectasy upon experiencing the flames.

Background
As a member the Fire Defense Agency, he rose up the ranks of the organisation before becoming a member of Special Fire Force Company 4 and gaining the respect of all his company. During his service, he taught Pan Ko Paat that the most important life to protect as a Fire Soldier was their own, as it was needed in order to continue saving others. Teaching Pan that he must always be calm and not react to the death of their subordinates, he told him he must also move around the scene of a fire with care and love.

During the Great Disaster in Year 196, Sōichirō received three scars across his face and had an Adolla Link. Following being scarred, he was noted to have changed. Later during the Great Disaster, following the mass outbreak of Spontaneous Human Combustion within Asakusa, Sōichirō's 4th Company arrived to aid the civilians and to search for any remaining Infernals that might still pose a threat. While his subordinates scoured to the area, Sōichirō approached the exhausted Benimaru Shinmon and Konro Sagamiya. The aging commander informed the pair of firefighters that Raffles III had formally decreed that their group would become the foundation of the Special Fire Force Company 7. Despite Benimaru's objection and Konro's hesitance, Sōichirō calmly explains the many benefits of this change, stating that he saw no reason for the pair to refuse. As he leaves, Sōichirō expresses that the powerful duo joining the Special Brigades would put his heart at ease.

Abilities
While Hague displayed no pyrokinetic abilities, he was a capable and dangerous fighter with an expertise with firefighting tools and found ways to formidably use them in combat. He could use safety wires to quickly constrict and restrain targets before they could react and use fire axes with deadly efficiency. Even in his old age, he was able to wrangle an empowered opponent with ease and even jump out of a second story window and land gracefully. He was also quite durable, being able to withstand attacks from Shinra with little injury and withstand injuries from Gold until his body reached its limit.

VS. Special Fire Force Company 4 arc
Through using their connection to Sōichirō's granddaughter, Company 8 are able to send Shinra Kusakabe to meet with the Captain in private. Upon Shinra coming to Sōichirō's office to ask him questions, Sōichirō requests that Shinra immolates him. This odd request helps to trigger an Adolla Link with The First Pillar who appears before Shinra. Once the vision ends, Hauge and the boy have a civil discussion about his scarring and knowledge of the Adolla. Their discussion is interrupted by the mind-controlled 119. Their violence triggers another Link with First Pillar that drives Shinra into a violent brainwashed state. When a primal Shinra lunges forward, Sōichirō interferes by blocking Shira's kick and binding the 119 to the wall (Karin and the others are revealed to be under the control of Haumea). The Captain then uses his cables to grapple Shinra, dragging him through the office window and into the courtyard. Sōichirō's talent with axes and Pan's ability to increase his fire resistances allow him to battle Shinra, however Sōichirō's desire to be burnt results in him deliberately taking several damaging blows. Shinra is driven back by the timely arrive of Ogun and Arthur. When Arthur steps forward to fight Shinra, he uses Hauge as a human shield.

In the aftermath of the battle, Shinra and Sōichirō discuss the possibility that the Evangelist will target this 'Fifth Pillar' like it has targeted Shinra in the past. Asako's treats Karin and the other victims of Haumea's mind control, who have no memory of the events but are now free of her influence.

Stigma arc
Sōichirō is attacked in his office by a member of the White-Clad. Even though he is able to set back his wires and pressing his back against his window, Hauge is stabbed in the back and is ultimately killed. His body is found trust up with his own cables and over a dozen shards of metal driven through his limbs and chest. In his dying moments, Hauge's feelings are transmitted to Shinra. While officially declared as a suicide, members of the Fire Force recognize that he was murdered. He receives a funeral with his comrades in attendance.
