The Squiggly

Newbie hikers Aya and Sana find a strange cave while they're out hiking. Aya heads inside, curious, and Sana nervously follows after her. Sana finds this more than a little strange, but they manage to leave the cave. Aya begs Sana to take a photo in front of the cave, but when she looks at the camera, she suddenly passes out like her soul has left her body.
