This has been bugging me for a while, but Tamamo Delmo's description is translated here as "supremacy of the home". In Japanese, Tamamo's title for her is "MY HOME Supremacy". MY HOME is a phrase used in Japan to refer to upscale Western-style houses. Supremacy here is refering to the art style suprematism. All of Tamamo's descriptions of the Tamamo Nine are very underhanded and insulting ("Beautiful talented secratary", for example, is intentionally phrased to sound like the tagline of a porno, because Tamamo's heavily implying she's a slut). In this cause, Tamamo's either saying Delmo lives in a tacky-looking art deco house or she's the type who would. Given that her name is a pun on Model, you can get a pretty good idea of what kind of character she is from that line.
I have no idea what a better translation for the phrase would be, but Supremacy of the Home doesn't get the meaning across at all.
