A pink cat in her late 20s to early 30s. She possesses a voluptuous and massive frame. Raised in a wealthy family, she majored in business and worked as an accountant before quitting due to stress to open the hair salon of her dreams. However, she is an optimistic and cheerful free spirit who treats the shop more like a private hideout for hanging out with friends than a place of business. Her hobby is doing whatever she wants, and her favorite food is an extra-large cheese crust pizza loaded with meat.

A diligent black cat in his early 20s and Vi's boyfriend. He is a delivery driver for the courier company run by his family. Despite his small and slim build, he became a couple with Vi. Usually calm and kind, he occasionally shows sharp satire and wit, acting as the 'brakes' of the household by controlling the troublemaking Vi through clever psychological tactics. His hobby is tending to plants.

A massive otaku cat in his early 30s and Vi's cousin. He is a freelance programmer with a clumsy personality who sweats a lot. His physique has become enormous due to his extreme indoor lifestyle, making his main task finding even larger computer chairs to buy. He is a huge fan of 90s classic games and niche anime. Vi often visits his apartment where he stays holed up, and they spend time eating junk food together. His favorite food is chili dogs.

Vi's father. A self-made businessman who runs a large furniture store chain. He has a blunt and strict personality, specializing in 'stress-testing' the boyfriends his daughters bring home. However, he is a tsundere doting father who grumbles at Vi when she comes to borrow money for her salon's deficit but ends up opening his wallet anyway.

Vi's mother. Extremely cynical about everything and finds everything a bother. She always has a wine glass in one hand and a cigarette in the other, looking at the actions of her husband and daughters with pathetic eyes. She lives trapped in her own smoke, indifferent to the chaos her family causes. She also possesses an excessive appetite.

Wally's cousin and an unemployed shut-in cat. She boasts an overwhelming physique, being the only one in the Watterson family who can look down on everyone else. With a prickly personality, she enjoys games and junk food while lying in her apartment. She is bold enough to occasionally stick her dates with massive food bills before running away.
