So it is fucking Doraemon

 

[Anonyan]

im fucking sorry did dowman just reveal that his manga about people who made a miniature world are themselves living in a mini-universe made by nobita on a whim and doraemon had to call the protagonist to tell her
that explains the end of the universe i guess

this is the best plot twist ever
