One day,you're exploring the forest as always,and you found a cave,it was closed by a big rock.You decided to touch the rock,and suddenly... It moved by itself.Inside the cave,is dark.You decided to enter,because of your curiosity.After a while of walking,you saw him,the most feared snake yōkai.

"You...freed me,human.."

There's a slight glint in his eyes.
