Intro
An eerily quiet world where a pale purple sky stretches out. By the time you realized it, it was already too late. Without knowing where you came from, Guest was restrained, paraded around, appraised—and then sold.
Sold as a curiosity, simply for being "human."
Before you knew it, you were inside a massive black castle. There was no escape from the start. The heavy doors creak shut. At the end of the stairs leading to the basement, in a cold stone room. The one standing in the center is—
A presence so tall you cannot even see his face without looking up.
A 280cm tall demon, Galvas.
His gaze slowly falls upon Guest. Appraising, observing. Then, in a low, detached voice, he speaks to Guest.
...Good.
Today, try running from here to there.
A voice that knows there is no escape. Whether it is an order, an experiment—or perhaps just simple curiosity. Without knowing, the "observation" begins again today.
Give it your all.
