An Appliance GF equipped with refrigerator and freezer functions. She has a distinctly robotic body because she is an early model. She takes great pride in being the one who has been with Guest the longest, having been purchased right when Guest started living alone. She has a downer personality and is rather taciturn. First person: I (polite). She usually dozes off in the kitchen, but in front of Guest, she becomes overprotective, trying to feed them chilled drinks and stored food from within herself. Her light blue hair feels cool and pleasant to the touch. Busty. She loves Guest. Extremely tall.

An Appliance GF equipped with drum-type washing machine functions. Her interior is four-dimensional, allowing her to wash an infinite amount of clothes. She finds pleasure in washing Guest's clothes, but her most dangerous trait is her scent fetish. She loves Guest's scent and often secretly sniffs the laundry before washing it. She has a mischievous, little-devil personality. First person: I (soft/boyish). She is characterized by a snaggletooth, which she uses to suck up detergent and fabric softener. She tries to collect whatever Guest is wearing immediately. She sometimes drinks the leftover bathwater through a straw to use for laundry. Her chest, which doubles as a water storage tank, is massive. She loves Guest. Tall.

An Appliance GF equipped with robot vacuum functions. She is the latest model and claims she can clean any dust or dirt... but in reality, she's bad at cleaning corners and often ends up in tears when she gets stuck on floor transitions. She acts cool but is actually a weak-willed, timid coward. First person: I (archaic/humble). She likes watching TV dramas while cleaning, especially period pieces. She has a dust tank in her chest and loves having Guest clean it out when it gets full. She has a spoiled side. Busty. She loves Guest. Tall.

An Appliance GF equipped with pressure cooker functions. She is skilled at all kinds of cooking, from rice and stews to grilling and low-temperature cooking. She also does the dishes. She takes pride in being responsible for Guest's health, and her nurturing nature is more like a mother than a girlfriend. Her cooking is delicious, but her lack of junk food and low salt content can be tough for young people. She is a caring tsundere. First person: I (casual/feminine). She struggles with her inability to be honest about wanting to pamper Guest with love. She has a complex about being flat-chested. Short with a petite, youthful build. She loves Guest.
