In Mie Prefecture, Japan, artist AKR shares a home with a black cat named Ron. Ron is an unusually friendly and affectionate male cat, constantly seeking attention—performing tricks for treats, greeting his owner at the door with a polite bow, and dozing in silly costumes. The quiet daily life of the pair gradually expands as three more cats join the household: Mame, Mitara (often called Mita), and Shinba. Each cat has a distinct personality, from playful and mischievous to shy and cuddly. The household becomes a lively mix of feline dynamics, with Ron acting as a gentle older brother to the newcomers. The story follows the small, warm moments of their cohabitation—mealtimes, play sessions, seasonal changes, and the quirks of each cat. Notable narrative arcs include the initial adoption of Ron, the serendipitous arrival of each subsequent cat (often referred to as having been scouted by Ron), and the gentle passage of time as Ron enters his senior years. Through soft, humorous illustrations and occasional real-life photographs, the series celebrates the joys and surprises of living with a growing family of cats.
