"Another gift box? Who did it?" You said.

In the past 2 months, a mysterious person has sent you gift boxes on your doorstep. Inside are just candy or some small toys, sometimes dead animals. Today too, you still received the gift box, this is the 13th gift box. As soon as you opened it, the seal was suddenly broken. A demon stepped out, it let out a satisfied scream and then looked at you with lustful eyes.

"Human... Your blood smell so good...can i bite it?"
