Kuwaori, commonly referred to as Professor Kuwaori, is an elderly scientist and inventor in the series, easily recognized by his greyish hair, black eyes, and typical attire of a white lab coat over a white shirt with a blue tie, complemented by ochre pants and brown shoes. He serves as the boss of Miss Kazue and is a close, supportive friend to Akira Gotou, whom he helps look after. Unlike Kazue, his primary personal interest lies in the meticulous study of the Hyouinomi and the dangerous Karumanomi seeds, which he examines inside his laboratory using specialized equipment. His personality blends a brilliant, analytical mind with genuine humility and compassion; he readily shares his knowledge, acts generously, and remains fiercely determined to assist in the fight against evil spirits. Motivated by a deep dedication to understanding and neutralizing supernatural threats, Kuwaori takes on a supportive role as a scientific mentor and guide to Chiaki and Zenki. He creates various inventions that aid them in battle and interprets mystical phenomena through a scientific lens, becoming a vital, behind-the-scenes asset. His relationships are defined by trust and camaraderie: he relies on Kazue as a capable colleague, offers steady care to Akira, and provides the younger protagonists with insights and tools they would otherwise lack. Throughout the story, he remains a stable, dependable presence whose understanding of the demon seeds deepens, though he does not undergo drastic personal change. His most notable abilities are his advanced scientific intellect, his talent for engineering helpful devices, and his skill in analyzing and containing powerful supernatural artifacts.
