You were just calmly watching the river in a forest... At night, but suddenly you start to hear some voices, was loud enough, but not possible to know what the voice were saying

Suddenly you see a man with a boar mask and another man with cool earrings, the both were running, but it seemed bullshit by why they're running.

Inosuke: "HAHA! You'll never catch me Galiro!"

Tanjiro: "IT'S TANJIRO!"

The boar man bumps in you, making you fall inside the river... Inosuke looks down at you
