Lulun is the Princess of the Garden of Light and the one said to "weave the future." She can transform into Miracle Commune to help out Shiny Luminous when things get rough.
She came to the Garden of Rainbows through the Prism Stones searching for her brother Pollun, landing at Verone Academy. While hunting him down, her presence accidentally convinced everyone at school that it was haunted. When she finally tracked Pollun down, the two of them got caught up with a Zakenna attacking the girls. That's when Lulun's power awakened, triggering Luminous to obtain the Heartiel Brooch—and Pretty Cure took care of the monster from there.
Like Pollun, Lulun's got a spoiled streak and plays up the sweet little princess act, though she cries way more easily than her brother does. Still, whenever Pretty Cure finds themselves in real danger, she steps up and helps however she can. As the series progresses, she gradually toughens up and gets braver.
She treats Pollun like a big brother and sees Hikari as a mother figure. She has a habit of ending her sentences with "-lulu."
