Publisher's blurb: ...A game about monster hunters on their periods... You’re a demon slayer, a magical warrior blessed by the moon with powers when menstruating. You use these powers to fight corruption wherever it roams, to beat back the foul forces of evil who lurk in the dark. The night is blessed by the moon and her children protect it. In Bloody Demon Slayers you play magical warriors tasked with protecting the world from evil. It draws on popular media such as Buffy the Vampire Slayer and Sailor Moon to create a unique peroid-based gaming system.
