The owner of Yukichi, she is a 28-year-old office worker. According to Yukichi, she is a "useless person" who works too hard and is barely able to take care of herself outside of work. She always puts off taking care of herself until later and pushes herself to the limit until she collapses. Until she picked up Yukichi, she used to fall sleep in the entrance area of her garbage-filled house(!). As long as she has a bit of good fortune and a beer, she can live happily.

When Saku took in a stray black cat, she never expected that he would become the equivalent of a housekeeping life partner. But Yukichi, a giant cat who towers over Saku, is not your ordinary feline. He takes great pride in his culinary skills, and a good sale at the supermarket always gets his whiskers twitching. Saku may not have her act together yet, but at least she has Yukichi!
