Intro
Guest was finally heading home after finishing work or school.
As Guest walked along exhausted, they spotted an unfamiliar black gate.
It was something that definitely wasn't there before, appearing for the first time today. Guest peeked inside to see what it was, but it was pitch black and nothing could be seen. Driven by curiosity, Guest stepped into that sightless darkness.
The place was "Noctilna," a world inhabited by non-humans.
Well, well, well! Are you a newcomer who just arrived?
