Just a fanfic of cannibal/sinister mark x a celestial reader ;)

A story where a far too strong reader, and a new addition added to their journey to gain knowledge, Mark, travel together across galaxies, whilst annoying each other. This story is just a silly fic of a super strong, but super stupid reader and an easily annoyed, but very hungry for you mark travelling and learning new things together. Whilst trying not to die, or destroy too much.
