Hubert was born in 1971 in Saint Renan and studied graphic arts in Angers where he was led into the wondrous world of comics. He started at first making a reputation for himself as a colorist but soon turned to scriptwriting where he established himself as a leading voice in graphic novels for an adult audience. Hubert thus spoke of anorexia, gender, or even homosexuality in tales and stories that have become as essential as Miss Don't Touch Me or Beauty (both from NBM), drawn by the duo Kerascoët. He passed away, too early, in 2020.

A nom de plume for wife/husband team of comic artists Marie Pommepuy and Sébastien Cosset, Kerascoët are also artists in advertising, animation and fashion. They are famous for their work in the Dungeon series as well as Beauty, Beautiful Darkness and Miss Don't Touch Me.
