Personality
Below is a brief description of the snooty personality. For more information, click here.
Yuka has a snooty personality, which means she loves makeup and gossiping. As a snooty villager, Yuka will first appear rude and arrogant towards the player, often talking about herself and her own experiences. She also speaks about the style and appearance of other villagers, usually other female villagers such as normal, peppy, and other snooty villagers. She will soon warm up to the player, confiding in them about their own feelings but still keeping subtly rude. Yuka will not get along with lazy villagers due to them not caring about their appearance or the lazy villagers hating what she eats, and she won't get along with jockvillagers because they will question her on her physical appearance and they won't worry about fashion. However, she will get along with cranky villagers due to their similar rude personalities, and usually normal villagers as well.
House[]
In Animal Crossing, her house had the bulk of the furniture from the Elegant Series along with the Ivory Piano, Dainty painting, Pleasant Feelings painting, a turntable, and pothos. She has the Classic Wall and the Parquet Floor. On the turntable she plays Soulful K.K..
In City Folk, she now has things from the Regal series, but not as many pieces of furniture she had form the Elegant series in Animal Crossing. Along with her furniture from the Regal series she has a tea set, a turntable (like her previous house), a caladium, and a blue bench. Her wall is now the Stately Wall, while the flooring is still the Parquet Floor. She still played Soulful K.K..
In New Horizons, Yuka now has most of her furniture from the Antique series. Along with the furniture from the series she has a Double Sofa, a Imperial Low Table, a Pendulum Clock, a Incense Burner, and a Phonograph that plays Soulful K.K. still. She has the Beige Art-Deco Wall and the Simple Purple flooring.
Despite the pleasant face she's always putting on, Yuka can actually be a bit pushy - particularly when it comes to input from others. She tends to forget that she may not always be right.
