[Reborn!] [Mukuro/Hibari] Ten Years Later

This story came from my frustration that the original work had no interactions between Mukuro and Hibari after the age of ten. It was just an idea that popped into my head... I honestly have no idea how to write a blurb... And, well, the title doesn't have much to do with the story either... That's all. The only pairing is Mukuro/Hibari, so please don't start ship wars. The characters are seriously out of character, so read at your own risk. Theme:
