Normal rikka

Rikka outside of PriPara.

She has long, dark blue hair that reaches her waist. Across the top of her head is a small braid which starts behind her right ear and ends across her left shoulder. She has two small silver clips holding her braid on the left side of her head. She has heterochromia iridium, meaning her eyes are two different colours. Her right eye is red, while her left eye is gold. She also wears a pairs of glasses. She is normally seen wearing the Paprika Private Academy uniform or in a long, white dress and grey cardigan with black shoes.

After undergoing PriPara Change her hair becomes shorter and is now styled into a thick braid which rests on her left shoulder. There are two small amethysts at the end of her braid. Inside of PriPara she wears the Nightmare Amethyst Coord, her PriPara Rare.


Rikka is a calm and quiet girl. She spends a lot of time reading books and studying, as well as sketching. She is very polite when speaking to other people. She doesn't have many friends and is very reserved. She learnt judo from her grandfather as a child, therefore she is incredibly strong. As well as self-defence she can also play piano and violin to a certain extent. Although she appears confident, in truth she is very shy and has trouble making friends, resulting in her being alone a lot. She likes designing her own clothes and wants to become a designer like her mother. However because of her shy personality she doesn't have the courage to tell others about it. After undergoing PriPara Change she becomes more confident and outgoing. She designs Holic Trick Coords with Cosmo and occasionally performs. Her signature Coord, the Nightmare Amethyst Coord, was the first dress she made after becoming a PriPara designer. She debuted as an idol before the start of the first episode, and has already reached Kami Idol status. She has her own Making Drama, called "Crystallise! My Phantom Eternal Memories" (クリスタライズ! 私のエターナルメモリーズ Kurisutaraizu! Watashi no etānaru memorīzu ).

A gag between her and Duck-E is that Rikka will whack Duck-E away to quieten him. This whack can be anywhere from a simple knock to a smash that will send him flying over PriParis and across the globe^^



Rikka first wanted to become a designer after her mother opened her store RubyS. Rikka adored her mother's designs and decided that she would too be a designer like her mother. One day, after closing hours, Rikka saw her mother at her desk, struggling over new design. Realising how difficult the road to designing was, she shut out her other ambitions and started designing herself. Her first clothes were for her antique dolls her grandmother gave here and slowly she started designing for herself. Being shy, she was never able to fully tell others about her love for designing.


One day after school, Rikka found Sophie in Fancy Mode in the school yard. When she approached her, Sophie asked Rikka to take her to Prism Stone and PriPara so she could performs ne meet up with her oneesama. Reluctantly, Rikka took Sophie to Prism Stone. After Sophie said she wanted to take her into PriPara, Rikka refused as she did not have a PriTicket, but found one in her notebook shortly after. After being half-forcefully dragged into PriPara by Sophie and Meganee, she met Cosmo, who offered her a job as a designer for Holic Trick. She initially refused, but realised that this was a chance for her to become a designer and became one.

Idol debut

After a few months working as a Holic Trick designer, Cosmo suggested to Rikka that she should debut as an idol. Once again, Rikka refused, believing that her place in PriPara was that of a designer's, and that she would rather see her designs worn by other idols on stage. Not ready to give up, Cosmo made Rikka her own Cyalume Rare coord so she could debut. After rethinking, Rikka debuted with Hirari/Hitori/Kirari and jumped to the "Promising Idol" rank of Debut Class. At the same time, she also told her mother about her designing and PriPara, who supported her and said that this is what she wanted.

Hisako, or Iona

After a year of PriPara, Rikka remembers her old friend Hisako and realizes that she's disappeared. On her way to PriPara after school one day, a commotion breaks out outside of the Prism Stone café. Diving for the spilling trays, Rikka and Hisako reunite. However, Rikka is stunned to know that Hisako has changed into Iona, and now goes to prestigious MR Private Girls' School. Rikka asks Iona about why she changed her name, but Iona refuses to answer. Iona then asks Rikka about PriPara, and Rikka responds by saying she's going to PriPara and is an idol, and invites Iona to join her. Iona initially refuses but eventually enters anyways.

Why, Hisako?

Six months pass since Iona and Rikka entered PriPara. Iona has been out of touch and the two have lost contact with each other. While walking around PriPara, Rikka encounters Iona again. After sitting down next to the river, Rikka once again asks Iona, or rather Hisako, changed her name. This time Iona gives in, and explains to Rikka that Iona didn't want to be known because of her name, but because of her talent. After a long silence Rikka suggests to Iona that she performs. Iona again refuses, but rethinks it and performs anyway. She ranks up to Major Class and she and Rikka become friends again.
