Cocoa has strawberry blonde shoulder-length hair with loose bangs, decorated with a cherry blossom hair clip on the side of her head. She has purple Tareme eyes.
Her work outfit is a pink and red variant of the Rabbit House Cafe's uniform: a long ankle-length black skirt, white blouse, waistcoat and bow tie. Her school uniform consists of a white skirt and a pink cardigan sweater.
Cocoa is an optimistic girl full of excitement with a bubbly disposition and unbridled enthusiasm that others find infectious and often convinces them to join her. She is very determined but unless it involves food or a topic interesting her, she is likely to become distracted. She also believes that she doesn't have any skill or a talent, with her confidence being so low that she's unaware of her mental arithmetic prowess and claims it's "nothing much".
Cocoa has been accused of having a sister complex and strongly desires to be seen as a mature, dependable older-sister figure by others. But her clumsiness and air-headed side usually discredits her attempts when she has to rely on someone else for help. As the smallest of her siblings she was influenced by her sister and brothers. Not only is she very passionate about baking and enjoys showing her love of bread to others at Rabbit House, but she also dreamed of becoming a magician, a lawyer, and even a novelist after meeting Aoyama Blue Mountain.
Cocoa arrives to Chino's town in order to attend its high school, having been influenced when she was little and visited as a child. She met Chino's Grandfather in this time, and attempted to cast a spell on him when he brought up wanting to become a rabbit to her.
As she is staying at Rabbit House, Cocoa quickly befriends Chino while working there.
