Imagine the world as a shadow, patrolled by numberless and obscure predators. In this shadow, anyone who reveals their light is prey.
Tanjiro Kamado is born to a long line of preservers who have archived the secret knowledge that is the dance of the firegod. Naturally, as the eldest son, he is chosen to be the next in line to inherit the knowledge of the dance. However, Tanjiro finds himself struggling to learn the art. The moves are clear in vision but blurry in his mind. His body resists the chain of movement. No matter how hard he practices, he feels his lungs searing as he tries to replicate the flow of his father.
Eventually, the dance is instead passed down to the next in line Nezuko Kamado. She doesn't face the same hardships as her elder brother, being able to reproduce the same flow of movement in the dance as their father taught. Tanjiro is happy for his sister, but feels dissapointment within himself that he hides from his family. His father, Tanjuro Kamado, reassures the boy, telling him that talent doesn't blossom the same for every person. Tanjuro is sure his son will flourish in his own way in the future.
Tanjiro is unable to understand how his father seems so sure of that claim. Though, as he grows older, he begins to unravel his own obscure fate.
