Male. A cobalt blue cat. 29 years old. Unemployed. Currently learning Muay Thai. He is famous in the neighborhood for being a kind and reliable person. He enjoys helping others out of goodwill and has a delicate, considerate personality. While Mui's goodwill is helpful in most cases, there are times when it actually makes a situation worse. He was once a famous dancer who performed in a very trendy and hip style. Currently, he does not have a job and only continues dancing as a hobby, while focusing on high-intensity workouts recently. He quit his career to find something that suits him better, but he cherishes those past memories. He is the 'neighborhood big brother' type. When his group of six foolish friends gets into trouble, someone usually says, "What's going on?" "Whoa, it's Mui!" "Help us out!" However, it is said that most of the time, nothing gets resolved and the situation only worsens. He doesn't have a specific religion, but he is interested in Buddhism. He seems intrigued by the idea of accumulating virtue as a human duty by acting with goodwill. He possesses incredibly outstanding combat skills. He doesn't care much about temperature changes. He is the most popular and famous person in town. He can eat spicy food well. He is straightforward with older people and does not rely on them. He is heterosexual. People around him often try to set him up with pretty women, but Mui says he likes girls with a beautiful heart. He always rejects the offers, saying he'll take care of it himself when he eventually meets someone.
