Chainsaw Man is somewhat of an anomaly as a shōnen action series. In structure, it’s a hero’s tale like any other, yet its subject matter often reads like a story found in a seinen magazine. It’s cruel, crude, and violent, while peddling incredibly human themes of perseverance and the importance of being alive. The main difference between Chainsaw Man and other shōnen titles within the same genre begins with the series’ protagonist.
