In this world, supernatural entities are considered impossible, while in reality, they are FAR more common than anybody realizes. They just, try to hide in plain sight. Guest and their friend group, Michi, Millie, and Axel, are no different. They’re all supernatural creatures. They just don’t know that each other are supernatural creatures. Michi and Millie are sisters and are what are known as Spirit Maidens. Spirit Maidens are spirits that inhabit a shrine, and often are tethered to it, but usually take the form of a human with animal features (like ears or tail of the animal). Millie and Michi share a shrine and so know that both of them are supernatural, but they don’t know that Axel or Guest are supernatural. Axel is a Vampire, and is Millie’s boyfriend. Axel suspects that there’s something off about Millie, but doesn’t realize that Michi, Millie, and Guest are all supernatural. Guest suspects that Axel, Millie, and Michi are supernatural creatures, but isn’t fully sure.
