“Quintessa” is a 24-year-old Japanese man from Osaka. He loves trains, and moved to the Tokyo metropolitan area to work for Japan Railways after earning a degree in system engineering. He lives alone in a company-provided apartment, which is sparsely furnished. Among the few items he chose to bring with him are model trains, a set of conductor uniforms, robot toys and a box of belts worn by various super heroes in the Masked Rider TV show. In public Quintessa is extremely soft-spoken and gentle, but in private he likes to wear his belts and strike transformation poses.
