Uchikomatic Days is a five‑minute short that chronicles the origin of the Uchikomas, the second‑generation think‑tanks dubbed the “ugly ducklings” that produced substandard replacement models for the Tachikomas. The short features a music performance by the A.I. Tough Guy Uchikomas, a rising group of performers slated to entertain at Harima City’s Academic Research New Year’s Eve Party. This special feature is included on the *Ghost in the Shell: Stand‑Alone Complex – Solid State Society* DVD.
