Profile overview
Zenitsu's fear is excessive but not false. He recognises that Demon Slayer work is terrifying and lacks the emotional tools to contain that knowledge quietly. His development is therefore not about discovering courage he never had; it is about acting while fully aware of fear.
Mastering one form rather than many gives his skill a clear philosophy. Repetition can turn an apparent limitation into precision, identity and reliability.
Zenitsu Agatsuma is a frightened swordsman with extraordinary hearing whose most impressive combat appears when panic no longer controls his conscious attention.

Symbolism and visual design
Lightning imagery turns accumulated tension into a single decisive release.
The contrast between constant noise and one perfectly focused movement defines his comic and dramatic rhythm.
Manga-versus-anime differences
Sound design is essential to a character whose hearing reveals emotional and environmental information.
Animation stretches stillness before acceleration, making the precision of his technique readable.
