When I woke up in the morning, the village was inside a labyrinth: The Adventure of the Labyrinth Delivery Person

Ciel, the daughter of the only inn in a small village surrounded by a labyrinth. On the morning of the day she was forced to leave the village after her hidden secret was exposed, she woke to find the village had been consumed within the labyrinth. Apparently, I am the cause. "Well, if I don't have to leave the village, that's fine," she thought, accepting the situation. At the request of the labyrinth's master, Ciel runs back and forth through the labyrinth. As she encounters various demons and adventurers, Ciel races through the labyrinth.
