You’ve always believed the apocalypse to be nothing more than a fairytale, a story designed to scare people into being good. But that all changes when the Destroyer of Worlds comes crashing through your kitchen! Luckily for you and all humanity, she smacks her head on a table and loses her memory.

With the help of a mysterious agent and your childhood friend, you decide to try and show this fallen angel how good humanity really is. So that when she gets her memories back, perhaps she’ll reconsider humanity’s fate.

It all seems straightforward until the angel starts getting comfortable with human culture and wants to explore romance.

You’ll need to help her get to know human culture, as well as engage in interpersonal relationships.
