HikaLala

HikaLala is the femslash ship between Hoshina Hikaru and Hagoromo Lala from the Pretty Cure fandom.

Canon
When Lala first arrives on Earth, she has no idea how to speak like a human, but after she starts to bond with Hikaru, Fuwa grants her the ability to do so.

Her surname is given to her by Hikaru, who believes that it suits how she arrived on Earth through descending from the sky.

Hikaru once said to Lala that she was excited to tell everyone that Lala was her friend and that she still wants to have fun with her at school.

In the beginning, Lala is hesitant to interact with Hikaru. They even had an argument once in episode 3, but she soon forms a close bond with Hikaru. She even starts to learn more about Earth thanks to her.

Hikaru, in episode 13, holds hands with Lala as the two run to school together.

They are usually seen smiling at each other.

The entire movie "Star☆Twinkle Precure: Hoshi no Uta ni Omoi wo Komete" is focused around them.

Trivia

 * Lala's birthday is on July 7th, making her star sign Cancer. Relating to the outer space motif, Lala's birthday happens to fall on Tanabata, the legend of which is related to the stars Altair and Vega.
