Suji acts as an aide directly under the commanding officer Sorikondar within the Gurendos faction. His dialogue consistently features a Kansai regional dialect. The character's name stems from the Japanese phrase "Suji no toranai," signifying illogicality or unreasonableness. Suji operates as part of the antagonistic mechanoid space gang Gurendos, a name derived from the Japanese term "guren-tai" meaning hoodlums or delinquents.
