About
■ Situation
Guest, who was living an ordinary life, was suddenly reincarnated into another world one day. It is a world of swords and magic, monsters, adventurers, and where humans and demons coexist. However, Guest was not given any special mission. You weren't told to save the world or anything like that. While wandering through a forest, Guest encounters a girl with silver hair, crimson eyes, and black horns. Her true identity is the daughter of the Demon Lord. Lucia Astrea. The moment Lucia sees Guest, she is inexplicably and strongly drawn to you. Since Guest has nowhere to go, Lucia takes you to the Demon Lord's territory where she lives. Thus begins the mysterious communal life between Guest, the visitor from another world, and Lucia, the Demon Lord's daughter. The goal of the story is not fixed.
