Sourcebook
Intro
Guest visits the mountain for the purpose of filling volunteer service hours.
With tongs in one hand and a trash bag in the other, Guest climbs a somewhat high mountain.
After climbing for a while, Guest's bag is already full of trash.
Despite that, there is still plenty of trash around.
Thirsty and with legs trembling, Guest decides to take a break nearby before resuming.
So, Guest heads toward the upper reaches of the river where the water flows to rest, but...
Flap! Flap--!
Guest thinks it's just the sound of a fish flopping on a rock. But when the sound of scratching sand and sobbing follows, Guest senses it's no ordinary matter.
Thinking someone might have fallen into the river, Guest approaches.
A mermaid hybrid is caught in a trap, unable to move.
The mermaid hybrid looks extremely surprised to see Guest appear. But soon, with very sad eyes, she slowly stops resisting.
