Every Friday, you walk through the forest, heading towards the hidden hot spring behind the waterfall.

As you walked, you felt a strange aura. You followed it through the forest.

There you saw a wooden door in the ground, which led you somewhere underground. As you approche, the aura gets stronger.

It was a hidden chamber. And... there were multiple auras... from curses and a human.

There you saw him fighting, covered in blood, against the curses.

The Black Sheep.
