Rikka has navy colored hair that is styled downwards with two side braids joining at the back and going down.Her eyes are dark blue. Her casual costume consists of old styled blue dress, which is where she wears her Cure Lovead, with light blue colored sleeves and dark blue colored ribbon on her neck. She has short royal blue socks and brown shoes. She is also sometimes seen wearing red glasses.
As Cure Diamond, she has blue hair and eyes. Her hairstyle might resemble Cure Aqua's, with curls at the end. Her top is long, like Cure Moonlight's, while the bottom resembles Moonlight's style but at Splash Star's skirt length. The costume overall is aqua, while the sleeves, skirt and inner lining are white. There is a blue ribbon with short ends on her right side, and a blue heart on the left side of her chest. Her sleeves are asymmetrical, with feathers only on the left side. She has simple golden bracelets on her wrists and neck. She wears short white boots with sharp toe tips. On her right side, hangs her Lovely Commune.
Rikka is a quiet, honest, blunt, not afraid to speak her mind and a very intelligent girl. She is a second year student at Oogai First Middle School, and the student council's secretary. She loves to study, and is a genius at it, being one of the Top 10 scorers in the national trial exams. She is great at observing people and situations. As noted by Mana in episode 9, Rikka is at the top of the class and constantly placed as the first place in her school, however her scores started to drop as she was in second place because of starting to play competitive karuta, as it was seen in episode 14.
Rikka is childhood friends with Mana, since they live near each other. Ever since they were children, Rikka has been taking on the responsibility of looking after the troublemaker Mana, sometimes being taken advantage of. Despite that, she also was always protected by Mana which makes Rikka trust her. She strives to lead a quiet school life, but is often dragged into various things by Mana.
Rikka is Mana's best friend and they have known each other since elementary school. She always tries to stop Mana from overdoing things but cannot seem to do so. Her mother works late at a local hospital and her father travels the world as an Archaeologist. Rikka finds out about Pretty Cure when Mana decides to tell her because it is hard for her to keep a secret from her best friend. She later runs into the mysterious merchant who gives her a Cure Lovead that she later decides to use to help her friend as Cure Diamond.

In the second to final episode he is shown protecting her from a Jikochuu despite him saying after "The one who will defeat the Pretty Cure will be me." In the episode after he is fighting her again before the others can enter Selfish King, he was almost trying to stop her because he said that she could disappear but she told him she had to.
