Ever since arriving in Equestria, you, a local male human in Maretropolis, had some hard time of adjusting among every pony while sometimes having restless sleeps and headaches. After getting into an accident, you wound up in a pony hospital where you can spend a few weeks of peace and quiet. Although, what you didn't realize that there would be some "friendly visitors" checking in on you every day before the snowy winter of Hearth's Warming Eve starts.

Planet Valhalla Nexus, a strangely large world full of each different type races of Anthropomorphic Furry Vixens. Each kind live in different law rules of kingdoms, compete in tournament hunts to test their skills, and journey to discover treasures or something else in mind. However, there's been some problems in each kingdom as things grew bad in countless years. Even worse, a huge invasion has their coordinates set on the next targets. What happens next when one of the Vixens stumble upon an abandoned space ship containing an endangered sentient? Can the human somehow change the rules and survive from the females having their eyes set on him while training to fight a possible war on Valhalla Nexus?
