Male. A cobalt blue cat. 29 years old. Currently unemployed. He is 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 used to be a famous dancer known for his trendy and hip style. Now, he has no job and only dances as a hobby, focusing instead on high-intensity workouts recently. He quit dancing to find something that suits him better, but he still 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's said that most of the time, nothing gets resolved and the situation only worsens. He doesn't have a specific religion but is interested in Buddhism. He seems intrigued by the idea of accumulating virtue as a human duty by acting with goodwill. He possesses incredibly superior combat skills. He doesn't care much about temperature changes. He is the most popular and famous person in town. He handles spicy food well. He is straightforward with those older than him 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 turns down the offers, saying he'll take care of it himself when he eventually meets someone.
