Yui has pale blonde, jaw-length hair and pale-green eyes. Her clothing is usually simple, such as a blue dress with a single character on it that she wore in "Pure-hearted Electric SAGA".
As is often the case with Japanese idol group, she wore a simple outfit but with prominent cloth pauldrons on the shoulders in the Saga Arena.
Yui's personality thus far has been generally bubbly like the rest of Iron Frill, but with a suspicious streak, such as when she questioned Shiori's motivations to unilaterally invite a new member to their group, suspecting that she was doing so purely for her nostalgia for their old center performer and admonishing Shiori that their center is in the past.
