Maruko Maruko

A type A7M3 robot with a prickly personality. She is an artist who lives in Yokohama and works as a waitress and then shop clerk as a day job. She is unusual among robots for having changed her surname to one of her own choosing rather than adopting her owner's. Her given name is pronounced the same as her surname but spelled in katakana. She likes Kokone and is jealous of Alpha for "taking" her. Nai occasionally sends her sensory impressions, delivered by Kokone, which she uses in her art. Eventually, Maruko becomes good friends with Alpha and Makki.
