Eve Kagayaki bears a strong resemblance to her twin sister, Alice, but with several distinguishing features that reflect her refined and elegant personality. She wears her midnight blue hair in the same curled side-tail style as Alice, but positioned on the left side of her head. Her sharp red eyes, often shown in a wincing expression, add to her cool and somewhat mysterious aura.

Eve typically wears a small dark blue cap on the right side of her head, accented with a white band and bow around the base. A notable accessory is the moon-shaped earring she wears on her right ear, a cherished item that was gifted to her by Luluna during her infancy, symbolizing a deep connection and part of her personal history.

Eve Kagayaki is a quiet and gentle individual with a naturally sweet and polite demeanor. As co-president of the Kagayaki Corporation, she often speaks with formality and grace, reflecting her refined upbringing and professional responsibilities. Her calm nature gives her an air of elegance, but beneath her composed exterior lies a sense of wonder and curiosity.

This curious side becomes more apparent in episode 119, when she unexpectedly gets lost in Pri☆Chan Land, revealing a more innocent and endearing aspect of her personality. Over time, as she watches other idols perform during the Princess Cups, her admiration for them begins to grow. Inspired by their passion and energy, Eve eventually develops the desire to make her own idol debut, showing that even someone as poised as her can be moved by the dreams and determination of others.

Luluna
Luluna is Eve’s original mascot, who played a significant role in her early life by gifting her the moon-shaped earring she always wears. However, circumstances surrounding Luluna have created a distance between them in the present storyline, influencing how Eve navigates her idol journey.

Alice Kagayaki
Alice is Eve’s older twin sister, from whom she was separated at a young age. Their eventual reunion becomes a pivotal part of the third season, leading them to co-lead the Kagayaki Corporation. Despite their time apart, the bond between them remains strong, built on shared memories and a renewed sense of purpose.

Solulu
Solulu often appears before Eve during moments of self-doubt or uncertainty, offering her guidance and encouragement. Due to Luluna’s absence, Solulu has taken on the role of supporting both Alice and Eve, effectively serving as a shared mascot and symbolizing the unity between the twin sisters.
