Cure Diamond

**Rikka Hishikawa** (or **Rachel** in the English Dub *Glitter Force Doki Doki*) is one of the five main Cures in *Doki Doki! PreCure*.

Her alter ego is **Cure Diamond**, or **Glitter Diamond** in the *Glitter Force Doki Doki* dub.

## Bio

### Appearance

Rikka has dark blue eyes and chest-length hair worn loose with a small amount pulled back to form a braid on the back of the head, held by a ribbon. At times she wears red glasses. Normally, she wears a white long sleeved blouse with a blue bow-tie, light blue pleat dress with light navy detail and buttons, black socks, and short brown boots. For summer she wears a white and blue sailor dress with light blue detail, and dark blue shoes with white socks.

As **Cure Diamond**, her eyes brighten and her hair turns light indigo, growing to knee-length and pulled into a thick ponytail held by a light blue and white piece with a blue diamond in the center. On each side of the head is a curled strand, with her bangs slightly curled. She gains blue diamond earrings and a gold choker to match her bracelets. She wears a light blue dress with white winged sleeves, one with a gold clasp around it, and accents of white frills and dark blue detail, connected to a small blue ribbon. The skirt resembles a fanned out wing, exposing white and milk blue fabric. On the chest is a blue heart with white fabric hanging from it. Her white boots have a milk blue cuff.

### Personality

Intelligent and introverted in comparison to the much livelier Mana, Rikka enjoys things like studying and is one of the top ten scoring students in the national trial exams. 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, if she becomes distracted by other things, like a current hobby, her grades are shown to suffer.

While she is kind and usually calm-minded, Rikka can be bluntly stern and she's not afraid to speak her mind. She strives to lead a quiet school life but is often dragged into various things by Mana, and as her childhood friend she feels obligated to look out for her and keep her out of trouble. But she also cares a lot about Mana and trusts her entirely as Mana has always protected her.

* In the *Official Complete Book* of *Doki Doki! PreCure*, it was revealed that Rikka does not have romantic feelings towards Ira, though there were initially plans to develop it. *"On romantic feelings: I don't feel that Rikka has romantic feelings toward Ira, though there were plans to develop it. But that would be overdoing it for Precure."*
