Taira has brown hair and olive green eyes. His usual outfit is the Jewel Academy's male uniform; a light yellow vest over a white shirt with a red tie, gray trousers and brown shoes.
Taira has a complex about his feminine given name Izumi, which influences most of his behavior. He requests to be called Roger, is rude to Jewelpets and has an overall abrasive personality from wanting to prove to others that he is manly. He mellows out as the show goes on and has meaningful interactions with Jewelpets, such as Flora and Opal.
