|Anime||Is the Order a Rabbit? Bunnisode 2|
Chiya has long, straightened dark brown hair vaguely reminiscent of a hime cut but with the forelocks longer and shaped differently. On the side of her head she wears a flower ornament with a ribbon. She has fair skin and green downward curving eyes.
Normally Chiya wears her work outfit, which is a dark green kimono with vertical stripes and a long white frilly apron over it.
A gentle and calming young girl, Chiya is formal and soft-spoken. She always appears to be in a light, airy mood and focuses on keeping the peace, although she can be a little air-headed. Even when she might be upset, she always keeps smiling.
Despite her ladylike behavior, Chiya has many surprising quirks one may not see at first. She finds pleasure in giving the sweets of Ama Usa An overly fancy names, such as "Red Jewel in a Snowy Field" and "Moon and Stars Reflected Upon the Sea". She also enjoys scary stories and disturbing others at times, and she dreams of becoming a samurai. She is genuinely kind, but at times she can be very teasing.
