    Basically, the continued Grim Adventures set in the 1990s, with Billy and Mandy slightly aged up and therefore slightly more mature themes. Set mostly in Mandy's POV. I suck at summaries. But I think it works better than one might think. Sorry for any cases of OOC. Read, review, enjoy :) (Eventual BillyxMandy)
