Witcherella

Ella, a witch in the Underworld Academy, is the only witch left with an evil aura. She's also the Grave Keeper, making sure the graves of important people are not disturbed. Her brother, the Grim Reaper, resides there too. He's a company for her in the graveyard.
Heck, it's the fashion era even for witches! Hence, she's given the name, Witcherella.
She has a pet cat (All witches do), but she doesn't know it's a HE, and he's a SHAPESHIFTER.

~Annual Witch Ball: Everybody is looking forward to that, even Ella. Can she be the jewel of the eye and give up her evil aura?
