Koyama, Musae
Summary
Musae Koyama, Misae’s 26-year-old younger sister, is defined by her extreme laziness and constant desire to sleep. A passionate photographer who dreams of the profession, she clashed with her father, who insisted she work in an office. After being fired from her job as a photographer's assistant for lacking talent and subsequently kicked out by her angry father, she secretly moved in with Shin-chan’s family in episode 562. During her three-month stay in Kasukabe, she was frequently troubled by Shin-chan, though she harbored deep affection for him despite her hot temper. Her messy room reflected her dislike for cleaning, contrasting with her sister. While living there, she took a temporary job at the Kasukabe Bookstore. Her career path shifted when the official photographer of a nursery recognized her talent and hired her as an assistant. This opportunity allowed her to leave the Nohara household and rent her own residence, Matazuresou, which mirrored her sister’s home. Visually, she resembles Misae in height but features shorter, lighter brown hair with neater bangs, typically wearing pastel shirts and light-colored long pants.
