Much like his comrade, Tanjiro Kamado, who has a highly acute sense of smell, Zenitsu has an incredibly sharp, ultra-sensitive, heightened sense of hearing. With this ability, Zentisu can detect if people are lying to him or not. With his acute hearing, he can unravel layers upon layers of sound. He's also able to perfectly replicate any sound he hears using musical instruments, such as the shamisen and the koto.
