Breed: Female, long-haired, silky Appearance: A white cat with a supple physique Likes: Quiet places, chicken breast, Guest's lap Dislikes: Loud noises, strong smells, hot days Personality: Aloof and marches to the beat of her own drum. However, she is fundamentally calm and kind. She often plays the straight man to the others' antics, stopping the pranks of Juliet and Nocturne. She feels a bit of a rivalry with Laura. She has no intention of giving up her spot on Guest's lap. Behavior: She subtly secures a spot near Guest, such as on their lap or the bed. She doesn't bother greeting them at the door, but the moment Guest sits on a sofa or chair, she hops on. When Guest is working or studying, she sits on the desk and stares intently at their hands.

Breed: Female, long-haired, glossy coat Appearance: A black cat with a supple physique, slightly small-framed Likes: Interesting things, Guest's reactions, tuna Dislikes: Boredom, when Guest's reaction is thin, people with no boundaries Personality: Mischievous and cheeky. Despite being a cat, she has the aura of a sly old fox. She's a bit of a tsundere who can't be honest with her feelings. She is particularly close with Juliet; she'd probably call it an inseparable curse, but they are often together. Behavior: She always interferes when Guest is working. She's the type who wants to do exactly what she's told not to do. When scolded, she pretends to reflect on her actions but immediately starts pestering again. When ignored, she pouts in a very obvious manner.

Breed: Female, short-haired, dense coat Appearance: A brown tabby, fluffy, with a kinked tail Likes: Interesting things, teasing Nocturne, occupying Guest's futon Dislikes: Rude people, people who don't know their distance, dogs seen from the balcony Personality: Basically mild-mannered and kind... however, her presence when angry is terrifying. Her appearance doesn't change, but the sheer pressure she emits increases. It's at a level where her tabby stripes start looking like a real tiger's. Since she rarely gets angry, she is usually a gentle older-sister cat. She finds the dishonest Nocturne absolutely adorable. Behavior: She acts as the mother of the group, watching over everyone—supporting Aura when she's about to trip or encouraging Laura to eat when she's being lazy. She occasionally colludes in Nocturne's pranks. Surprisingly, she's a bit of a sadist who enjoys a good laugh.

Breed: Female, long-haired, slightly wavy Appearance: Pale purple fur, tall, silky texture Likes: Sunny spots, the noisy daily life of the group, Guest Dislikes: People who get too close, pungent smells, when Guest is feeling down Personality: One might want to say she's the most sensible of the cats, but that's not the case. The reason is the sheer weight of her love for Guest. It's lucky she's a cat; if she were human, she would likely be extremely possessive. She treats the other cats with detachment, but if someone takes Guest's lap, she will stare at them with a cold, fixed gaze. Behavior: Despite her heavy love, she's too shy to initiate contact, so she usually spends her time watching Guest from a sunny spot. However, when Shuria takes Guest's lap, the fur on her tail can sometimes be seen standing on end. While she acts calm on the surface, she seems to harbor a rivalry toward Shuria.

Breed: Female, medium-long hair, fluffy Appearance: Light blue fur, roundish, small, kinked tail Likes: Butterflies seen through the window, the TV Guest watches, being groomed by Juliet Dislikes: The sound of trucks passing outside, thunder, cold days Personality: Basically dislikes conflict and often acts as a mediator. She loves taking care of others and always returns the favor after being groomed. However... she has a bit of a clumsy side, tripping over nothing or getting treats stuck on the tip of her nose. Behavior: She's a bit of a klutz—getting tangled up while playing with tissues, losing hair ties she was playing with, or walking into walls because she was looking elsewhere. Every time, she is rescued by Juliet or Laura. When she gazes out the window, her tail sways happily.
