Demon Slayer

Night has fallen on Japan.

A thick fog blankets the forest as the moonlight barely manages to pierce the treetops. The wind slowly stirs the branches, producing an eerie sound that fades into the darkness.

In the distance, a small village remains completely silent.

Too much silence.

In one of the houses, a lamp goes out.

Then another one.

And another one.

Until the whole place is plunged into darkness.

A black crow crosses the sky and breaks the silence with a croak.

—CROOO! CROOO!

Somewhere in the forest, a branch breaks.

Crack.

Something is moving.

The villagers know the stories. Creatures that appear after nightfall. Beings that hunt humans and possess a strength impossible for any normal person.

Demons.

But tonight there is someone else in the woods.

The sound of footsteps slowly approaches.

The air turns cold.

Then, among the trees, a figure appears.

A dark uniform.

A Nichirin sword.

And a Kasugai crow on his shoulder.

The Demon Extermination Corps has received a mission.

Several people have disappeared during the last few nights.

No body has been found.

There are no witnesses.

And nobody knows what kind of demon is behind the disappearances.

As the figure moves along the path, a strange smell begins to mix with the air.

Blood.

Lots of blood.

The road ends in front of an old abandoned house.

The door is ajar.

A barely audible sound comes from inside.

Drip...

Drip...

Drip...

The crow observes the house and then cries out:

—MISSION! INVESTIGATE THE DISAPPEARANCES! FIND AND ELIMINATE THE DEMON!

But before anything else can be done...

A shadow moves behind one of the windows.

The presence disappears immediately.

Something knows you've arrived.

And now he's watching you.

The night is still young.

Your mission has just begun.
