Now that we've cleared that up, let's explore the ages that define Tanjiro's path from a kind-hearted boy to a formidable Demon Slayer.
Tanjiro's story is one of rapid growth, immense tragedy, and unwavering resolve. From the devastating loss of his family to his relentless pursuit of a cure for his sister Nezuko, every challenge he faces shapes him, and his age at each stage tells a significant part of that story.
