Jiro Matsumoto is a Japanese manga artist notorious for his dark, provocative, and highly satirical works, often classified under the seinen and ero guro genres. His raw, scratchy, and deliberately crude artistic style perfectly complements his bleak narratives, which unflinchingly explore themes of violence, social decay, and dark psychology.

Matsumoto’s most recognized work is the disturbing psychological thriller Freesia, set in a world where legalized revenge killing has become a government service; the manga was later adapted into a live-action film. Other notable works include the erotic thriller Velvet Kiss. Matsumoto stands out in the industry for his unique punk aesthetic and his uncompromising, underground approach to storytelling.
