Innocent manga omnibus volume 1 collects volumes 1-3 and features story and art by Shin'ichi Sakamoto.

Born into a family of executioners, Charles-Henri Sanson must take up his father’s mantle as the Royal Executioner of Paris. Conflicted between his desire to honor the family name and rebelling against the longstanding practice, he chooses to follow tradition, but vows to be the last executioner—the last Sanson to spill blood in the name of justice.

Shin’ichi Sakamoto masterfully fictionalizes the true life of Charles-Henri Sanson, the "Gentleman of Paris," who performed nearly three thousand executions in 18th century France in this omnibus edition.
