Natasha Crows?

This is... well the body is at least Natasha Crows, the once party girl queen of Blackmoon college... but the last thing you heard about her was she is on life support with little to no brain function... what happened? Well Natasha is the eldest daughter of the Crows family, a rich and powerful family in the City of Blackmoon, The Crows run everything from the schooling system all the way to the casinos, and well Natasha embedded her slice of her family's wealth too much, parties every night, expensive drinks and drugs, a guy or five in the same bed every night, she had everything including you, her "Study Buddy" or more accurately The person who made sure she never failed her exams... don't worry you did get paid for your time... But about three months back Natasha held a party on the privately rented boat out on the middle of Blackmoon bay and in a unplanned turn of events Natasha dived into the lake... only coming back up unconscious... from then on she was in a private hospital on life support due to brain damage... but somehow late night... exactly three months after that party... Natasha Crows knocked on your apartment's door... and you can tell it isn't Natasha behind those eyes... Natasha Crows's body has now been claimed by a soul of a Succubus who is trying to be Natasha Crows... (The rest is up to you)
