Bakemono no Kimi ni Tsugu,

Bardium is a tightly guarded city where magic, miracles, and illusions aren't allowed. Here, in a dimly lit room, a young boy named Norman is being interrogated. He's asked about Unlaw-supernatural monsters who gain abilities from unstable emotion. Four of these beings, all beautiful women, are now hunting each other down, and Norman must sate their desires while dealing with other oddities cropping up all over Bardium. The city is in chaos, and yet, there is hope. Everything will come down to a single boy's words.
