Benoît Ers won a comic contest in Angoulême. Two years later, he began a study in fine arts in Epinal. He quit after six months, however, because he got a contract to become an independent illustrator in Liège. It was there that he met scenario writer Dugomier. After producing some short stories and illustrations for Spirou, Ers and Dugomier created the series 'Muriel et Boulon' at Lombard. In 2004, they replaced the 'Muriel et Boulon' series for 'Les Démons d'Alexia', a more realistic series that appears at Dupuis from 2004.
