HPxover. With Voldemort in public eyes, Hogwarts can’t get any more interesting, can it? Wrong. Throw in two new ‘students’ and the most unlikely DADA teacher, then add the mafia and a dash of Rokudo Mukuro, and what do you get? AU, w/plot --not crack--

Summary inside. Fem! Tsuna. 00F27 NosaruUni. HarryGinny. DracoHermione

Add the TYL Varia to Hogwarts. Also, the fact that they are going to attempt to defend the castle... with Adult Mammon. Mix it all up and the end result? Total insanity. MamBel26 XS. T for pervertedness.
