   Summary

   Here in Underground City, things are quite different. Monsters were never banished under Mt. Ebott, instead monsters and humans live together but... no one ever said it was easy. Hopefully, this will just be another day at work for you, but you better hurry, the tables fill up quickly!

   A twist on the traditional Undertale story... or is it?
   You are the main character!
