Personality
Confident and somewhat playful, Riruka appears to be an impatient, hot-tempered young girl, that unleashes her wrath even towards her comrades if they disagree with her. She claims to be with her group only for her own agenda and not out of any loyalty to Kūgo.

History
Riruka's history is unknown and mysterious although for her own reasons she is following Kūgo, who seems to know secrets about the Kurosaki family. It is unknown if she was involved with that history.

The Lost Substitute Shinigami arc
Riruka appears outside the Unagiya Shop along with Kutsuzawa, claiming that they had failed in their goals and that it was Kūgo's fault for not showing them her face. She claims that Kūgo is not her leader but their comrade, stating that he wasn't any good at wooing people which Kutsuzawa contradicts much to Riruka's annoyance. She still claims otherwise but Kūgo asks her to be quiet and not reveal their plans to those who can hear before walking off.
