Emiru Aisaki

Emiru is very overprotective and does not like being looked after. She also admires the Pretty Cures because of her wish to be a heroine herself, but often gets carried away when trying to protect others thanks to her exaggerated actions. Flaws aside, she is still caring toward her friends and tries her best to cheer them up. She also has a strong passion for singing and playing the guitar, despite her brother not supporting her at first. Like anyone her age, she still has many childish traits, such as sleeping with stuffed animals and not believing anything until there is evidence. She also has a strong emotional side, which once resulted in her losing her voice. Emiru first befriends Ruru when the latter inadvertently compliments her. They become better friends as Ruru tells off Masato for being sexist towards Emiru and Emiru finds out that Ruru is an android. Eventually, Ruru becomes Emiru's Pretty Cure partner. 11 years later, Emiru has become a guitar idol. She manages to contact Doctor Traum and gets the chance to meet the new Ruru he invented. When she encounters the young android, she has mixed emotions as Ruru is not the same anymore. Trying to reconnect with Ruru, Emiru plays the guitar and sings to her. Ruru evenutally sings along and they slowly bond with each other again.
