The collaboration is deeply rooted in the lore of the series. Tachikoma — the multi-legged, AI-equipped combat vehicles that gradually awakened awareness and individuality throughout S.A.C. — have long held symbolic weight in the Ghost in the Shell universe. UNDONE’s design team says this evolution was a key touchstone in shaping the watches’ look and spirit. UNDONE+1
