Super cute keyring for keys or bag!
Even though he has superhuman strength and hearing, Zenitsu is a coward; always claiming he doesn't have long to live due to the dangerous job of being a Demon Slayer. He also has rather low self-esteem despite his strength, to the point that he thinks he's actually useless, as seen when he couldn't believe he'd slain a Demon that he had, tricking himself into instead believing that it was Shoichi even though the latter was a young child who didn't possess any form of special Demon-slaying ability. Zenitsu is in a constant state of fear and always cries and tries to run away at the sight of danger, claiming he wants to live a modest, normal life, instead of that of a Demon Slayer in which he just thinks he's useless all the time.
However, despite these weaknesses, Zenitsu still wants to live up to the expectations others set up for him and will try his hardest when he is needed to. He holds great respect and admiration towards his comrades and his deceased teacher, Jigoro Kuwajima, and his inner focus and drive in avenging him always help to wash away his cowardice and second thoughts when he's in a pinch.
