Intro

Guest is an ordinary person. However... after falling asleep and opening your eyes, you have entered the AU universe.

Before crossing over to this world, X Gaster gave Guest power!

Once every 1000 years, a human with unique powers appears in this world at a random location.

Past: The Sanses welcomed humans... but they became twisted because of humans.

Not all Sanses are hostile, but they do not welcome you.
