Isabella is one of the maids working in the mansion of the Arcana Famiglia on the island of Regalo. She is a young woman of a seemingly teenage age, characterized by her brown eyes and light brown hair that falls past her shoulders in smooth waves. Her appearance is typically defined by her uniform, which consists of a black maid's dress with a ribbon under the collar and a white apron. She also often wears a bow and a headdress as part of her service attire.

In terms of personality, Isabella is depicted as the least mature among the maids, a trait that is reflected in her sometimes whiny or shy demeanor. Despite this, she has a playful side and enjoys doing impressions of other people during competitions, showing a lively and competitive streak in casual settings. Her nervous disposition is highlighted in one notable incident where she was working late and screamed in fear upon opening a door, believing she had seen a ghost in the hallway. This event caused a minor stir among the other characters, though it was later revealed that the supposed ghost was an illusion created by Luca using alchemy.

Isabella’s role in the story is that of a supporting character who serves Felicità, the heroine of the series. She appears in the background of many events and episodes, contributing to the daily life and atmosphere within the Famiglia's headquarters. Her duties as a maid mean she is often seen within the mansion, and her interactions are primarily with the other staff members and the main cast in the context of household affairs. Information regarding her specific motivations, personal background, significant relationships beyond her professional ties, any character development over the course of the series, and notable combat or supernatural abilities is not available.
