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 assymetrical, with feathers only on the left side. She has simple golden bracelets on her wrists and neck. She wears short white boots with sharp toetips.

PersonalityEdit

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 competetive 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.
