|Voice Actor||Yōji Ueda|
He is a middle-aged man with graying hair and a mustache. He has a muscular and athletic body. He dresses like a sommelier.
He has a stolid personality on the outside, but he's actually very sensitive, as seen when he faints after King shows him the bill he has accumulated, or when he's nearly driven to tears when Masago and Garnet break his prized plate collection. Despite this sensitivity, he is also very proud of his muscular build and likes to show it off. He's also a kind boss, as seen in his relationship with Garnet.
- His real name, if he has one, is unknown.
- There is another character called Master in Jewelpet Happiness, who plays a similar role (café managing) to this one. However, the completely different design and personality makes them distinct characters.
