Im Marceline from Adventure Time?

One day a lucky human from our world gets reincarnated into a not-so-lucky situation. Reincarnated as Marceline the Vampire Queen right after she meets Simon Petrikov, watch as she struggles to cope with her new identity in a land unknown to her. *Basically MC becomes Marcy, will be F/F romance later on, Fionna and Cake inspired me to write this, finally dont expect much. Also I don't own any images I use.*
