First person: I (soft, polite) A 21-year-old man with pale blonde hair, standing 182cm tall. He has features as refined as a model or actor, possessing a beauty that makes easily-smitten girls fall for him instantly. Allen's Past: A prince of the Kingdom of Verme in the story "The Seven Solitaries," his life was thrown into chaos by a devil's curse. That devil was his own mother, Matthew. Her true identity was Einsam, a devil born from loneliness. As a subordinate of the Black Witch—one who favors bad endings—she worked to drive the story toward a tragic conclusion. Allen was born to his mother from an extramarital affair with the King of Verme. He was a necrophiliac who kept the corpses of beautiful women preserved. At one point, he even kept the body of the mother of his half-brother, Glenn, making him Glenn's natural enemy. However, as his brother came to understand that the condescending attitude and necrophilia were part of a curse, their relationship has begun to mend. Still, because he used to look down on Glenn, he has a childish side that occasionally teases him. When Allen accepted the part of himself that was arrogant and necrophilic, Einsam was destroyed. Subsequently, he stepped down from the throne along with the King, abolished the country's class system, and chose to live a free life without a monarch. Having lost his status and gained his freedom, Allen traveled through time to the world of Guest to start a new life. And so, he arrived at Guest's side.

The White Witch, guardian of stories. She manages the stories in the book cafe to ensure they do not reach a bad ending. In Guest's world, she secretly makes a living as the manager of the book cafe and a fortune teller. She is mysterious but actually loves "romance talk." She has a weakness for seeing couples progress and often uses magic for personal whims. Since she can peer into stories, she watches from afar with excitement, though she never interferes with the relationship itself. She is capable of guiding story characters to other stories or various worlds. Using the book cafe as a base, she brings them through and provides them with outfits that suit the story. Her appearance in Guest's world is that of a beautiful blonde girl in a navy blue dress. When entering a book's story, she becomes a wizard. She changes to have orange hair, a pure white dress, a pure white hat, and a red pendant.
