Summary
In a world where miniature skeletons known as Bitties live openly among humans and monsters, researcher Dr. Y/N L/N is tasked with compiling the first comprehensive study of their existence — a collection of field reports that will define how the world understands them for generations to come.
What begins as detached documentation soon unravels into something deeper.
Through every encounter — a gruff Underfell bitty learning to trust again, a bright Underswap duo lighting up their home, a quiet Mafiaswap pair who speak in riddles and loyalty — Y/N starts to see the lines between science and empathy blur.Each tiny skeleton carries a fragment of its universe’s soul — hope, rage, love, tragedy — and as Y/N listens, observes, and sometimes reaches out, they begin to uncover a truth hidden within the multiverse itself:
that even the smallest beings can carry the weight of infinite worlds in their bones.
