Airy, whose full name is Airy Ardet, is a central female character from the Shining Hearts game and its anime adaptation, Shining Hearts: Bread of Happiness. She is a young human girl from the island of Wyndaria, though some sources also identify her birthplace as Crantor. In the anime, she works alongside her two close friends, Neris and Amil, at the Le Couer Bakery. She is one of the three main heroines, and her character class is that of a Priest. Airy is fifteen years old.

Airy has a gentle and kind-hearted personality. She is typically cheerful and friendly, but beneath her caring exterior, she can struggle with feelings of insecurity and self-doubt. Despite this, her big heart makes her always willing to assist those in need. As a skilled baker who takes her craft seriously, she is always experimenting with new recipes to improve her bread, driven by a creative passion for her work.

Her primary role is as a steadfast companion to the protagonist, Rick Elwood. In the story, Rick, who has lost his memory and emotions, washes ashore on the island where Airy lives. She and her friends rescue him and he begins working with them at the bakery. Airy is dedicated to helping Rick recover his lost heart. A key part of her motivation stems from her own past as a lost memory and a fellow drifter, which creates a deep sense of empathy for the protagonist. Her goal is to collect "hearts" to help the mysterious girl who arrived on the island, ultimately hoping to restore what has been lost.

Airy shares a very close and important bond with Rick. They are childhood friends, alongside Neris and Amil. This relationship is marked by deep tragedy. Prior to the events of Shining Blade, their homeland of Crantor was attacked by Imperials. Rick volunteered to fight to protect Airy and the other two, but they were all slain during the invasion, leaving Rick as the sole survivor. After this, Airy continued to exist as a spirit who was unable to ascend to the Spirit World. She was later discovered by a character named Sakuya, who preserved Airy's spirit as a Soul Blade. As a spirit, Airy still longs to help Rick, showing that her compassion transcends death. She pleads with another character, Rage, to help reconcile with Rick, noting that Rage carries a similar sorrow and could help bring Rick back to his former self.

As for her development, Airy undergoes a transformation from a living girl to a spiritual entity, yet she retains her core desire to aid those she cares about. Her journey is one of seeking resolution and peace for both herself and Rick, moving from a tragic past toward a hopeful future. Her notable abilities are tied to her class as a Priest. This grants her healing magic and support skills, which she uses to protect and care for her allies, reflecting her nurturing personality.
