Lulun, the Princess of Light introduced in the sequel series, wields the power to connect with the future while sharing a home with Hikari and Pollun—the latter initially vexed by her affectionate persistence but eventually embraced as a brotherly figure. Her design mirrors Pollun’s, with a white body adorned by a golden crown, pale pink fur accents framing her neck, ear tips, and tail, and a vivid magenta orb embedded at her throat. Heart and diamond symbols grace her head, complemented by heart-shaped markings encircling her eyes.

Beneath her sweet, whimsical exterior lies a timid spirit prone to tears under stress. Yet her journey reveals steady growth: when stranded and mistaken for a discarded toy by young Nozomi, Lulun chooses steadfast loyalty over escape, comforting the girl and later guiding her to reconcile a secret guilt with her parents. This arc underscores her blossoming courage and emotional insight.

In battle, she deploys tactical prowess, conjuring barriers to protect allies like Hikari and Nozomi during clashes with the antagonist Viblis. Her powers also amplify Shiny Luminous’ strength via the Heartiel Brooch, a device tied to her Miracle Commune transformation.

Initially defined by clingy dependence, Lulun’s bond with Pollun matures into playful camaraderie by the series’ end. Balancing her royal poise with a tender protectiveness, she emerges as both a compassionate guardian and a resilient figure, embodying quiet authority alongside her nurturing heart.
