Minette is an automata puppet crafted by the puppeteer Mise Altoise. Awakened during an eru energy meteor shower, she was discovered in a secret room and instantly recognized Leicester Maycraft as her paternal figure upon first encounter due to his status as the initial person she saw. Her physical form resembles a ten-year-old child, radiating an innocent and caring demeanor.

Her core functions through Ale crystals, a mystical energy source. Aberdeen Roland pursued her core to save Miriam Roland, another automaton with a fragile body who became Minette’s close friend. Their bond involved Minette sharing tales of the outside world with the confined Miriam. In the original visual novel narrative, Leicester fashioned a replacement core called the "Blessed Campanella" to sustain Minette while allowing her original core to preserve Miriam.

Residing with Leicester’s adventurer group, Clan Oasis, in Ert’Aria, Minette catalyzed multiple adventures often centered on uncovering her origins or resolving Ale-energy conflicts. A pivotal revelation exposed Miriam as an automaton secretly crafted by the Roland clan to house a human spirit through a hidden art.

Minette’s journey explores artificial life and familial bonds. Her relationship with Leicester anchors her emotionally, while interactions with Agnes Boulange—Mise Altoise’s daughter and apprentice—link her to her creator’s legacy. Her existence bridges human and automata experiences, notably through her bond with Miriam and the core-transfer resolution.
