Well, it has happened! The laws of the universe is broken by the looks of chapter 40! Teddy bears can now talk. @_@
So possible answers that we, the vampire detectives, have found out:
1. Trapped soul inside the teddy bear. (Like Anju's doll from KARIN)
2. Kayuki's mind has finally gone to "that world". (Nuuuuuuu! )
3. Aliens controlling the teddy bear.
