Hikari's got black, short, spiky hair put back with a pin and busty, long bangs. Her eyes are a little sharp, maple-colored, but with a soft and vivid feel. She's pretty short and under-developed. Her skin is, like her sister, a bit tanned, but not as tanned.
Hikari is cheeky and childish. She's not very close to her sister, mostly because she want to be independent and not carried throught life. Hikari is a also very tomboyish and from she was five she didn't wear a skirt until she started at her job in the Maid Café and when she started PriPara.
