Konro Sagamiya, former vice-captain and later company commander of Special Fire Force Company 7, presents a calm and diplomatic counterpoint to Captain Benimaru Shinmon's abrasive nature. He acts as a stabilizing force yet harbors deep self-doubt about his leadership, convinced his true role is support due to his perceived lesser power compared to Benimaru.
Physically tall at 188 cm, he has black hair tied in a ponytail and a prominent horizontal scar between his nose and eyes. Tephrosis causes charring on his shoulders and arms, requiring bandages, and casts sickly shadows under his eyes reflecting his chronic condition.
His background revolves around maintaining peace in Asakusa alongside Benimaru. During a massive Year 196 Infernal outbreak, they faced a pyrokinetic Demon Infernal matching Konro's abilities. To protect an exhausted Benimaru, Konro fought alone, ultimately incinerating the creature by pushing his powers beyond limits. This victory came at a cost: the Infernal scarred his face with its horn, and the power overuse triggered irreversible Tephrosis. When Company 7 formally organized, Konro declined the captaincy due to his illness, becoming Benimaru's lieutenant instead.
A Third Generation pyrokinetic in his prime, Konro ignited his shoulders and forearms to enhance his physical strikes with devastating force. His raw power matched Benimaru's signature "Crimson Moon" technique, later revealed as a replication of Konro's own style. He demonstrated this power by creating massive craters, notably defeating the Demon Infernal. However, Tephrosis now prevents him from using his abilities without severe repercussions: immediate collapse and accelerated degeneration of his condition. Even minor exertion risks incapacitation.
Konro's loyalty and strategic mind prove vital. He mediates during Company 8's visit to Asakusa, explaining Benimaru's capabilities. Later, during a coordinated attack on Asakusa, he directs Company 7's defense from a watchtower. Witnessing Benimaru targeted by Arrow while vulnerable, Konro attempts to intervene but collapses from Tephrosis. Desperate, he mentally summons Shinra Kusakabe via an Adolla Link, leading to Shinra deflecting the attack and enabling Benimaru's victory, highlighting Konro's unwavering commitment to protect Benimaru.
He advocates for Shinra and Arthur Boyle's training with Company 7, personally instructing Arthur in swordsmanship to counter feints and illusions. Investigating alone in the Stigma arc, he isolates himself to lure an assassin, defeating them through swordsmanship despite his frailty. He participates in discussions on Adolla Links, drawing from his Demon Infernal encounter. During the Ōbi's Rescue arc, he stays in Asakusa to avoid implicating his district in Company 8's conflict. His story culminates when Shinra Kusakabe's manipulation of time during the Great Cataclysm reverses catastrophic events, restoring Konro to life.
