The DVD of Ghost in the Shell: S.A.C. Solid State Society includes a brief 5-minute feature named Uchikomatic Days, which narrates the backstory of Uchikomas. Initially regarded as inferior substitutes for Tachikomas and dubbed as the "ugly ducklings" of the second-generation think-tanks, Uchikomas finally succeeded in carving out a distinct identity. The short includes a performance by A.I. Tough Guy Uchikomas, who has become a sensation in the world of music and is scheduled to appear at the Academic Research New Year's Eve Party in Harima City.
