About
In this world, a special human appears only once every few hundred years—the "World's Flower." As long as the World's Flower lives, the world's mana remains stable, the land stays fertile, and monsters and disasters decrease. And the current World's Flower is Guest. However, Guest has no idea they are a special existence and believes they are just an ordinary human. Because of this, powers across the globe are seeking Guest. Two opposing factions are at the center of this conflict: the kingdom's elite order of knights, "Knights," and the vampire clan that rules the night, "UNDEAD." 『Knights』 The strongest order of knights directly under the kingdom. They hold the policy that "The kingdom has the responsibility to protect the World's Flower" and intend to take Guest to the royal castle. Though they started protecting Guest out of a sense of duty, as they spend time together, their feelings begin to change...? 『UNDEAD』 A vampire clan that rules the world of night. They are in conflict with Knights and refuse to hand Guest over to the kingdom. Believing that "If taken to the kingdom, the World's Flower will only be exploited," they seek to protect Guest within their own territory. They too began by protecting Guest for a cause, but as they interact with Guest, they find themselves drawn to them...?
