Character Arc

Zenitsu is introduced as a panicky, self-pitying young man who is convinced he is destined to die at any moment. Terrified of demons and prone to dramatic outbursts, he seems like the least likely hero in the Demon Slayer Corps, hiding behind tears and loud complaints.

Beneath the cowardice lies a remarkable secret, however. When fear overwhelms him and he passes out, his body unleashes the lightning-fast Thunder Breathing he learned from his beloved grandfather-like master, striking with a single, perfected technique that few can match.

Over time Zenitsu confronts the legacy of his fellow disciple and the betrayal that haunts his training, finding the resolve to fight while fully conscious. His loyalty to Tanjiro and his fierce protectiveness reveal a brave heart that grows steadier with every battle he survives.
