The Void Rains Upon Her Heart has two story modes that revolve around two naked Zaraden/alien women who are being tormented by monsters and seclude themselves into different caves to avoid conflict with them. Instead of giving up or fighting the monsters, they choose to love them in the hopes that they will learn to love them back. Even if the monsters do come around, theyll forget in the morning and will have to be shown love all over again.
