Description
This is my first fanfic so it might not meet your expectations. This is a bnha and undertale crossover where (y/n) is Sans' and Papyrus' younger sibling. (y/n) is enjoying a nice picnic in waterfall with everyone until they get sucked into the bnha universe. BTW (y/n) is going to be classed as gender neural. Of course (y/n) can look however you want like every reader insert and with opportunities to choose, so feel free to describe (y/n) through your eyes it would be interesting to see how many differences there are. apart from (y/n) and this story/plot nothing belongs to me. obviously bnha characters and undertale characters belong to their creators but unless I say so the art is not mine and most of it was found on google so I'm sorry that I can't give credit where it's due.
