Charles-Henri Sanson remains a historical figure of significant mystique. Sanson served as the royal executioner of France during the reign of Louis XVI and administered over 3000 executions in his tenure. Infamous for his advocacy for the use of guillotines, Sanson would later go on to use the same instrument to execute Louis XVI himself. Shin'ichi Sakamoto deconstructs the mythos of Charles-Henri Sanson by crafting a dramatized story about the man, though much of Innocent is made with excess creative liberties.
The story across the three volumes collected in this omnibus focus primarily on Charles-Henri Sanson's early childhood leading up to his coming of age where he serves his father as an apprentice. Charles' father, his father's father, and his father's father's father were all executioners, so the practice remains a family business. Though Charles is compassionate and loathes the idea of killing, he meekly follows his father and grandmother as they push him hard into the career. The story is pretty perverse at times, depicting sexual abuse and violence rather freely. I personally don't take issue with this if it serves the story well, but here it comes off as oddly grotesque and even off-putting. Charles' and his siblings experience some incredibly vile bits of abuse, much of which kicks off the opening few chapters. It'd be understandable if some readers couldn't make it past this point because it is rather awkwardly written and depicted. Though the story does improve in the latter half of this omnibus, the lingering ick from certain portions never really dissipate.
Shin'ichi Sakamoto's artwork is breathtakingly great though. A fine line is used throughout, crafting some truly picturesque backgrounds. Sakamoto brings the historical setting to life easily, with grandiose depictions of the architecture, fabrics, weapons, etc. of the time. Though Sakamoto does draw some pretty gory segments, the artwork remains refined and alluring the entire time.
