Mafia's Strongest Witch

The Mafia knew of the Arcobaleno.
The Strongest Martial Arts user,
The Strongest Illusionist,
The Greatest Scientist,
The Great Seer,
The Combusin Commander,
The Number One Hitman,
And the Stuntman hated by Death.

Or do they really know of the last one?

Skull De Mort.
The civilian dragged into the Mafia for his uncanny healing ability with his Cloud Flames and his semi-hermit personality makes him hard for most people to read him.

But there were more sides to the 'mask' he wore.

'He' was actually Zephyranth Nectarine Celestine Potter-Black-Flamel-Peverell. The GWL, Witch who Won, Merlin's Successor, The Second Morgana Le Fey, Mistress of Death, and the Grand Dutchess of the Wizarding World.

She was also two other personas:

Arazel, Italy's Lord of Crime.

And Lilianthe, a famous traveling songstress of pop, Rock, jazz, blues, and indie.

Since that Fated Day when Luce backstabbed them with the Curse, it was hard for her to trust those outside her circle. Sure there was Tsuna and Uni who were more decent and helped to relieve them of their curse, Zephyranth thought she could finally relax and vanish from the Mafia.

Unfortunately for her, the Arcobaleno don't let one of their own leave the group so easily.
