Wish, secretly Prince Chris of Fairyland, balances his royal duties with a thriving career as a popular male idol in the human world. He is recognized by his light blue short hair and striking crimson eyes. Sent by his mother, the Fairyland Queen, his critical mission is to gather Happiness Tones – vital energies required to prevent Fairyland's collapse following the disappearance of princesses and their realms.

He initially secured the magic stones enabling three young girls to form the idol group Lilpri. However, Prince Chris labors under a severe curse: physical exhaustion forces him to transform into a rabbit. Extended periods as a rabbit risk permanent consequences, stripping his ability to speak or sing and trapping him forever as an ordinary rabbit. Only his loyal grey cat Ma-Pet, Vivi, shares this dangerous secret.

To manage his curse, the Queen provides him a specialized watch. This device controls his transformations, detects spatial tears in Fairyland, and offers communication features like holographic projections and message recording. Once cheerful and charming, the curse's weight erased his smile until the influence of the Lilpri group helped him gradually rediscover emotional openness.

His journey culminates with the discovery that Lilpri themselves embody the "Ultimate Shine," permanently breaking the curse and restoring him fully to human form. Freed from this burden, Prince Chris continues his dual existence: safeguarding Fairyland while excelling as a human-world idol, embodying his connection to both realms.
