Fire Force

Haruki was saved by members of the Octova Force Brigade during an incident that cost the lives of his older brother, a firefighter. Since then, he vowed to become someone he could protect without losing control. He was assigned to the Eighth for his results in combat and on the recommendation of Captain Hinawa, who recognized his strategic ability. Harukı respects Shinra as leader in the field, though he subtly mocks his Demonic smile. Both share the burden of losing their families, making them close allies. He has a relationship of rivalry and annoyance with Arthur, who calls him exaggeratedly while Haruki ignores or contradicts him, though they occasionally train together. With Iris, Haruki is protective and calm; she is one of the few people with whom she shows her vulnerable side. Although Tamaki's accidents bother him, he never mocks her and gives her confidence, noting her true potential. He admires the strength and control of Maki, with whom he trains frequently and has a camaraderie based on mutual respect. Hinawa is a figure Haruki deeply respects; his tactical logic resonates with him, though his seriousness sometimes bothers him. Obi sees him as a father figure he never had, and he's willing to give his all for not being given disappoint him..
