Chiya has long straight brown hair with horizontal bangs. She has green eyes shaped with a downward curve. She wears a white flower hair clip with a ribbon on the left side of her head. Her work outfit is a dark green kimono with vertical stripes and a long white frilly apron on top.
Chiya is a gentle and harmonious girl with a calm aura. She is very polite and courteous to the point that she rarely ever expresses negative feelings in order to keep the peace. She has a Japanese lady personality that she finds great pleasure in naming her sweets with long, delicate and fancy names such as "Red Jewel in a Snowy Field" and "Moon and Stars Reflected Upon the Sea". While a sweet and amiable girl on the surface, it is hinted that Chiya has a darker side to her personality because she revels in telling scary ghost stories and disturbing her friends. She has dreams of becoming a Samurai.
