Canon
Rikka and Ira are rivals, who make little interactions troughout the season, the two make a major interaction when Ira got hit by a thunder and lost his memory, Rikka took care of him. Ira called her an 'Angel' in episode 26. In the second to final episode, he is shown protecting her from a Jikochuu. His motivation for fighting her is likely because of his own fear of losing.

While traveling in the air, Ira got struck by a lightning bolt, causing him to fall in the sea. The next day, Rikka, along with Raquel were at the beach and found him, washed up on the shore, unconscious. Rikka, decided to helped him, despite knowing how dangerous he was. Suddenly when Ira woke up, he said that he didn't remember anything of what had happened or who he was, from this, Rikka then knew it was amnesia. Seeing the bad condition Ira was in, she took him to her home. Rikka cared for him, made food for him and also fed him. From this, Raquel became jealous. Rikka told her friends about what had happened and that Ira had amnesia. Once Aguri saw him, she transformed and tried to defeat Ira, however Rikka was protecting him, suddenly Gula came attacking them, Cure Ace left.

While the girls tried to avoid Gula's attacks, Ira hit his head hard, leading to him regaining his memories. He knew he was bad, however this time he was in the Cures' side. He protected the Cures from Gula's punch by blowing them away. As he saw that the Cures were in good condition, Ira left. He went in a mysterious place, in which he took off his bandages, meaning that he had recovered from his injuries. In multiple episodes after his memory came back, Ira was shown to either defend Rikka from Marmo and Bel, or prefer fighting her over the other Pretty Cures. In the finale of Doki Doki!, after the Pretty Cures had won the final battle, Ira said maybe it wasn’t so bad that they had, while looking at Rikka.

After the Cures battled Bel, Ira was last seen looking at Rikka longingly before Marmo urged him to leave. He then disappeared with Marmo and mouse Bel into the sunset.

In the Official Complete Book of Doki Doki! Pretty Cure, 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."
