Doraemon is her love interest. When Mii-chan is on trouble, Doraemon will always help and rescue her.
Mii-chan get along pretty well with her "mother-in-law", much to Doraemon's dismay.
- In the 1973 anime, Mii Chan has a wider face, and in the 1979 anime, Mii Chan is a grey cat with a white face and ears.
- Viewers should not confuse Mii-chan with a toy cat of the same name, who appears in Oh, Lovely Mii-chan!
