Hiiro Yano

Hiiro is a sleek university student with a mature attitude. As a VJ, her knowledge in art allows her to build the unique worldview of the unit. Since she majors in psychology, she acts as the counselor of the unit and listens to the members' consultations, but scolds anyone who becomes too selfish (e.g. she scolds Muni for not eating healthy foods).[1]

Hiiro often acts like a caring older sister or even mother to her friends and fellow RONDO or younger characters. She often takes charge of feeding and caring for Nagisa, and repeatedly gives Tsubaki advice on life and relationships, which has led to her jokingly comparing her welfare check to "parents' day" and referring to herself as "mama". This often overlaps with Aoi's ikemen and older brother habits in various RONDO segments, creating an interesting dynamic between them.

Hiiro's hair and eyelashes are of a light lilac color, and she has slanted gray eyes. She originally had wavy sidelocks in promotional material, but after the 3.0.0 update in Groovy Mix, her sidelocks are slightly trimmed.
