Rana

Rana is the femslash ship between Aida Mana and Hishikawa Rikka from the Pretty Cure fandom.

Canon
When Rikka's parents were talking to Mana's parents at Pig Tail, Mana ran straight to Rikka. They introduced each other and shook hands. Since then, they have been friends with each other for roughly 12 years, where they have looked out for each other.

Upon returning from her first battle, Mana is greeted by her worried classmates and teacher. On the way home, Rikka suspects Mana is hiding something and tries to get her to spill the beans. But when Mana tells her she became a Pretty Cure, Rikka doesn't believe her. The next day at school, another Jikochuu appears and freezes anyone it came across. With no other choice, Mana transforms into Cure Heart, to which Rikka realizes Mana was telling the truth the whole time. During the battle, Mana is hit by the red beam and turns to stone, so Rikka steps in to try and help. In that moment, she notices a button on the back of the Jikochuu. As she reaches out to press said button, the Jikochuu notices her but as she turns to stone, her finger presses the button, freezing it. This allowed Heart to turn back to normal and cleanse the Jikochuu. On the way home, Rikka forces Mana to carry her school bag but forgives her for everything.

After investigating Mana's Lovead, Rikka and Mana head to Pig Tail for dinner. As they part ways, Mana asks Rikka to join her as a Cure, with Raquel thinking she'd be perfect as Mana's partner but she declines the offer. The next day, Mana and Rikka find Joe. Rikka tries to question him, but he forcibly gives Rikka a Lovead and leaves. The two fairies then realize a Jikochuu had appeared, so the girls rush over to its location. Mana transforms but as she struggles to fight the Jikochuu, Rikka remembers when she first met Mana. Her Lovead shines, and with Raquel as a Lovely Commune, Rikka manages to transform into Cure Diamond. She quickly cleanses the Jikochuu with Twinkle Diamond, and accepts her duty as a Cure.

Whenever Makoto was spending time with Mana Rikka used to get jealous easily, Rikka is her secretary as well. They always protect each other. Every time Mana exaggerates helping others, she always tries to stop her which she never succeeded in doing.

Fanon
firstly sailed because whenever Makoto was spending time with Mana Rikka used to get jealous easily making fans interpret it as if Rikka had a crush on Mana, however 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." Instead, it was confirmed by the director of Doki Doki! after the finale aired that Diamond was in love romantically with Heart, in turn how she freed herself after becoming frozen by her own attack is considered as a plot hole. Therefore, in theory Diamond sacrificed herself for Heart. There's multiple works of them together and some artworks when it is seen both of them very close made by Kamikita Futago who both are creating the manga adaptions of Pretty Cure.

It is a very popular though its sometimes overshadowed by its rivals ships such as ManaRegina and Rira.
