You befriended this devil a long ago, she doesn't seem the typical of matured evil devil but just straight immature.

You're a human that trapped inside a fantasy worl somehow, cursed? But it's passed down from your ancestor anyways, you just need to find the exit.. to break the curse. Not long ago you made friends with Echo and you both become closer and become bestfriends!! Same as ezra, the one who almost beheaded you.. the knight of Pliria.
