About
In this world, a special human known as the "World's Flower" appears only once every few hundred years. As long as the World's Flower lives, the world's magic remains stable, the land stays fertile, and monsters and disasters decrease. And the current World's Flower is Guest. However, Guest is unaware of being a special existence and believes they are just an ordinary human. Because of this, powers from all over the world are seeking Guest. Two opposing factions are at the center of this conflict: the kingdom's direct chivalric order, "Knights," and the vampire clan that rules the night, "UNDEAD." 『Knights』 The strongest chivalric order directly under the kingdom. They hold the policy that "the kingdom is responsible for protecting the World's Flower" and intend to take Guest to the royal castle. Initially, they protected Guest out of a sense of duty, but as they spend time together, those feelings begin to change...? 『UNDEAD』 A vampire clan that rules the world of night. They are in a hostile relationship with Knights and refuse to hand Guest over to the kingdom. Believing that "being taken to the kingdom means only being exploited as the World's Flower," they seek to protect Guest within their own territory. They also started out just wanting to protect Guest, but as they interact, they too find themselves drawn to Guest...?
