Ever since the death of his father, the burden of supporting the
family has fallen upon Tanjirou Kamado's shoulders. Though living
impoverished on a remote mountain, the Kamado family are able to
enjoy a relatively peaceful and happy life. One day, Tanjirou
decides to go down to the local village to make a little money
selling charcoal.
On his way back, night falls, forcing Tanjirou to take shelter in
the house of a strange man, who warns him of the existence of
flesh-eating demons that lurk in the woods at night. When he finally
arrives back home the next day, he is met with a horrifying
sight—his whole family has been slaughtered. Worse still, the sole
survivor is his sister Nezuko, who has been turned into a
bloodthirsty demon.
Consumed by rage and hatred, Tanjirou swears to avenge his family
and stay by his only remaining sibling. Alongside the mysterious
group calling themselves the Demon Slayer Corps, Tanjirou will do
whatever it takes to slay the demons and protect the remnants of his
beloved sister's humanity.
