Lip emerged from a Fairilu Seed during the Birth Festival, initially struggling to open her Door of Birth until encouraged by Nozomu, a human boy whose kindness sparked her success. This moment forged an enduring bond between them, later deepened when she learned Nozomu could transform into Drop, a fellow Fairilu.

She enrolled at Saint Fairilu School, mastering skills like flight and forging lasting friendships with Sumire, Himawari, and Rose. Her dynamic with Rose shifted from rivalry to mutual respect through shared trials. Lip’s compassionate spirit drove her to rescue classmates like Akiakane, a dragonfly Fairilu, during perilous lessons.

Adopting the human alias Yumiri Hanasaki, she pursued an idol career while concealing her true identity from Nozomu to safeguard his emotions. By the third season, her aspirations shifted from stardom to becoming a cupid, prioritizing others’ romantic happiness.

A pivotal moment arrived when she was selected as the Fairilu Diva after performing the Song of Regeneration with Gardenia, a role demanding detachment from personal ties. This compelled her to temporarily withdraw from Nozomu and her idol pursuits. Collaborating to heal Sui and Gardenia, she relinquished the Diva title, reconnecting with Nozomu and reviving her idol path.

Her design features gradient-hued wings, light red hair in curled pigtails, and a signature pink fairy cap. As an infant, she sported smaller wings and a simple dress. Her human guise includes a coral-red tulip-themed dress, while her Diva form dazzles with a golden tiara and ornate gown. Her Fairilu Key, vital for magic, evolves across seasons, gaining crown motifs and richer pink tones.
