Tatsuki Fujimoto's Chainsaw Man is known for its over-the-top action and brutal scenes of gore, yet it has always maintained a sense of thematic layering beneath its eye-catching panels. Chainsaw Man tackles various themes including love, change, and most of all, fear. Nowhere is that clearer than the series’ most jaw-dropping panel, which makes no attempt to hide Fujimoto’s message about fear.
