Andy Dōmyōji is a clansman of Scepter 4, the organization recognized as the Blue Clan. Born on June 4 under the Gemini sign, he stands 182 cm tall at 19 years old, with vibrant orange hair, green eyes, and AB blood type. His personality sharply contrasts between duty and leisure. Professionally, he demonstrates self-control and responsibility, particularly when obeying superiors Seri Awashima or Reisi Munakata—figures he fears alongside snakes. Off-duty, he reveals childish traits: explosive energy that swiftly turns to fatigue, dramatic emotional outbursts, demands for others' food, easy discouragement, and a tendency to spill secrets. Quick-tempered and impulsive when insulted, he often requires physical restraint from fellow clansmen. He indulges in gossip and mischief, frequently roping Akira Hidaka into pranks. A past incident involved his care for a supernatural Strain horse. The creature kicked his face, leaving a horseshoe-shaped mark, then escaped. Pursuing it with clansman Himori Akiyama, he encountered HOMRA members in Shizume City. Taunted by the Red Clansmen—especially over whether horses deserved human rights—Dōmyōji nearly drew his saber, escalating conflict until the Strain fled with Anna Kushina. Despite frustration, he reported the outcome to superiors. He participated in key Scepter 4 operations: an airport mission to arrest the Silver King, where his helicopter commentary drew reprimand; the failed containment of Mikoto Suoh’s prison break; perimeter security during HOMRA’s Ashinaka High School takeover; and battles against Red Clansmen where his Lieutenant reminded him to stay composed. At Ashinaka, he witnessed a silver light beam’s emergence. As a Scepter 4 member, he wields the standard-issue saber Excalibur and channels the Blue Aura of his clan. Previously, he commanded Squad 4 with recognized skill, though peers like Akira Hidaka and Ren Gotō disrespected him, prioritizing age over rank. His mixed heritage includes a French mother. In the non-canon spin-off "The Idol K," Scepter 4 operates as an idol agency under Munakata and Fushimi. This scenario explores idol production without detailing Dōmyōji’s specific role.
