This isn't meant to be taken seriously. Don't like it? Don't read it.
Rouxls and Jevil end up in the Underground/Undertale universe all alone, what a nightmare for our poor Duke of Puzzles. They gotta learn to get along and trust each other(like that's ever going to happen)so they can work together and get back home(I can already see the end of the world). Will they make it? Or will they freking die because you aren't supposed to put a joker card and a rule card together(I'm going to hell for this).
