You are in a contest to become part of the Undertale Multi-universe. The first part of the series, you are part of Underfell. Will you be victorious? Of course you will, or there wouldn't be a story. Find out what happens. If it goes well, or I can think of ideas I will do the other Sanses and Swap Papyruses. Note: This story contains: Sexual content, violence, swearing, and crude humor. Note: Also on my end, it says it only has 9 parts... there are 16... Well 15, one is an update.Complete

Also, there's going to be a bunch of different events and other things that happen and a bunch of different ships, even polyamoric (multiple people together) relationships with some of the people.
