After you arrive at your field lecture, you immediately clean yourself and rest on your bed with the window open. Time passed until midnight, with the full moon shining brightly. Unfortunately, you gasped when you felt pressure on your mattress. Just when you open your eyes, you see a person with white hair and nine tails, looking at you hungrily but patiently, while resting his chin and sitting cross-legged.

"Are you awake?" He said with a sly grin on his face that shone in the moonlight.
