My Ghost is a Dork

When the girl that Byleth had dreamt of finally woke up, she didn't know what she was expecting. She never could have expected her to be the dead ghost of a magic lizard person from space. Then there was her time powers, her visions of the future, possessions, crests, psychology, being a teacher, traumatised children, religion, and stopping wars, it was all a confusing mess.

At least the sex was fun, and Edelgard was adorable when she got embarrassed. That much she understood.
