Sōichirō Hague

is the Battalion Commander of Special Fire Force Company 4.

Appearance
Sōichirō is an elderly looking man with short light coloured hair and three scars across his face. He wears glasses over his squinted eyes, and while on duty, wears bunker gear.

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. After receiving three scars across his face, he was noted to have changed.

Following the mass outbreak of Spontaneous Human Combustion within Asakusa in Year 196, Sōichirō's 4th Brigade arrived to aid the civilians and to search for any remaining Flame People that might still pose a threat. While his subordinates scoured to the area, Sōichirō approached the exhausted Benimaru Shinmon and Konro. The ageing commander informed the pair of peacekeepers that Raffles III had formally decreed that their group would become the foundation of the 7th Special Fire Brigade. Despite Benimaru's objection and Konro's hesitance, Sōichirō calmly explains the many befits of this change, stating that he saw no reason to refuse for the pair to refuse. As he leaves he leaves, Sōichirō expresses that the powerful duo joining the Special Brigades would put his heart at ease.
