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.
