When Sawada Tsunayoshi, Vongola Decimo and the glorified Neo Vongola Primo, died at the tender age of forty-five, he did not expect to wake up thirty-two years ago in his bedroom. Nor did he expect to wake up in a parallel world with absolutely different rules. [Disclaimer: I do not own KHR, its plot, or its characters.] [If any of you saw this under Ithias_Crimes in Archive of Our Own, no worries. That's still me, and I've decided to put the fic there as well.] [This version will still be ahead of the AO3 one in terms of chapters, but the one in AO3 would be edited and may be a little better in quality. A little.]
