B*MO (Bérénice Motais de Narbonne) hails from Berry, studied literature in Paris, then trained at L'Estienne (School of Arts and Graphics) before enrolling at ENSAD (School of Decorative Arts) in the animated film program. In 2016, she wrote her thesis, which addressed the representation of women and feminism in comics.

In 2017, she made Astrale, a stop-motion animated film, a dreamlike depiction of the protagonist's puberty, which won the award for best student film at the Rennes National Animated Film Festival, as well as the special prize at the Ca' Foscari Film Festival in Venice in March 2018.

In 2020, Actes Sud BD released Quitter la baie, the first installment in the Metastation series, which once again uses fantasy to explore adolescence and the changing contemporary world. The latter are at the heart of Metadoggoz (Actes Sud BD, 2023), a story of urban science fiction and a community of young social outcasts, drawn in black and white, capable of originality that fuses styles raging from manga and the most recent french comics.
