Ai-chan is a baby fairy mascot hatched from a mysterious egg. Initially bonded to Cure Ace as her companion, she was separated during a clash with the Selfish King, reverting to an egg discovered in a river by Joe. Her true identity is Princess Marie Ange, whose existence split into dual halves: one of purity embodied by Cure Ace, Madoka Aguri, and one of malice manifested as Regina. After prolonged separation, Ai reunited with Cure Ace, restoring their partnership. She has fair skin, large blue eyes accentuated by curled yellow markings, and pink hair styled into heart-shaped buns fastened with yellow flowers. Pale pink heart markings adorn her cheeks, while her attire includes a yellow onesie with a white bib marked by a fuchsia heart, light purple booties, and delicate angel wings. She shares a protective, familial bond with Aida Mana and Kenzaki Makoto, who are playfully dubbed her mother and father. Joe, her discoverer, remains privy to her history. Her speech uniquely concludes with phrases like "~kyupi" or "~kyupirapa." She channels powers typical of fairy allies, summoning Loveads to aid protagonists and conjuring protective barriers. Her name, rooted in the Japanese word for love, mirrors her thematic essence. Her narrative arc tracing her fragmented existence underscores themes of unity and redemption.
