While working as a graphic artist, he turned to comics in 1993 by writing the script for his fantasy series 'Arkeod'. Unable to find a suitable artist, he took on the artwork himself, with the help of Masaki Okumura for the designs and architecture.

He became the artist of the main series in 2004, finishing the first cycle of this sci-fi saga with Crisse as the scripwriter, but starting the second one as a complete author in 2008. Together with Mazzarino, he developed another fantasy series called 'Verseau', of which two books were drawn by Alain Peticlerc in 2004 and 2006. Mitric also scripted the 'Arkeod' spin-off 'La Voie du Silence', that was drawn by Manu Grey and published in two books in the same period. As a scriptwriter, Mitric additionally created 'Tessa - Agent Intergalactique' with Stéphane Louis and 'Anatole Deparadis' with Philippe Fenech in 2004.
