Marie, a teenage witch, navigates life in Azami’s slums, bartering homemade potions for secrets amid the district’s hardships. Unbeknownst to most, she is Maria Azami, the vanished princess who abandoned her royal title, adopting a humble alias to conceal her lineage. Her disappearance’s cause remains shrouded, though ties to her past endure: Alka, an ancient sorceress and her former mentor, still influences her magical journey, while Chrome, her ex-protector turned café proprietor-turned-soldier, resurfaces during crises linked to the Demon Lord Abaddon.

Marie’s routine intertwines with Lloyd Belladonna, a Kunlun ally, through chaotic spells cast by Alka—such as her accidental transformation into a butterfly, which leads Lloyd to discover her vulnerable, human form. Though these curses spark irritation, she blames Alka’s mischief, sparing Lloyd her wrath. Beyond personal entanglements, she is thrust into kingdom-wide strife when Abaddon’s assault leaves her royal pin amid ruins, spurring allies to unravel misconceptions and stage her rescue.

Her cluttered dwelling contrasts her poised magical persona, often tidied only by Lloyd’s intervention. Adorned in witch’s garb, glasses, and a hat, Marie balances her covert identity with magical tradecraft, navigating both absurd mishaps and grave perils without compromising her secrets.
